Happiness, charity, religiosity, and liberals vs. conservatives

In a recent paper, Jamie Napier and John Jost argue that the reason conservatives are happier than liberals is that they are, for ideological reasons, not pained by observing high levels of income inequality. They draw this conclusion on the basis of responses to a survey item about attitudes about meritocracy that ranges from a scale of "hard work generally doesn't bring success--it's more a matter of luck" to "hard work pays," which Will Wilkinson shows cannot do the job of supporting their explanation:
I strongly agree that success, understood as a significant upward move on a valued status dimension, is largely a matter of luck. But I also strongly agree that hard work (in a society with decent institutions) usually brings a better life. It’s possible to work hard and achieve a better life without ever winning anything you’d count as success. So I haven’t a clue how I’d answer this question. Do I believe in meritocracy or not?
He observes that there's also a much better explanation for the answers to that question than assuming a blindness or lack of care about inequality:
If one wants to see a meritocratic bent as a common cause of conservative leanings and higher happiness, here’s a less tendentious explanation. (1) Those with a greater sense of the efficacy of their behavior — with a greater sense of being in control — will tend to (a) think hard work brings a better life, (b) be happier, (c) see policies that seem to penalize hard work as unjust. (2) People likely to see high taxes as an unjust penalty on hard work tend to identify as “conservative.”
And a further problem about attributing a blindness to inequality to conservatives is that conservatives give more to charity than liberals, as Wilkinson's commenter John Thacker points out (and I've previously observed at this blog). Thacker attributes the difference to religiosity; again, I've previously pointed out that he is apparently correct on this point (also see this post and the previous reference on conservatives vs. liberals), that the religious give far more to charity than the secular, even if you don't count donations to churches. (But apparently Christians are well-known in the service industry as lousy tippers.)

The same Napier and Jost paper is discussed at Marginal Revolution, where commenter DocMerlin points out that:

A rather simple answer follows with (A) and (B) being true statements that result in the same statistics without the rediculious "conservatives are happy with evil" result that the study got.
1)
A) Women are much more likely to self report depression and unhappiness than men are.
B) Men are more conservative than women.

2)
A) Divorced/unmarried women are on average more liberal than married women
B) Married people are happier.

3)
A) Conservatives are more likely to attend church regularly
B) People who attend church regularly are found to be happier and healthier than those who don't (on average).

4)
A) Liberals feel guilty for their own success.
B) Conservatives don't feel guilty for their own success.

Another possible explanation is that liberals and the secular value truth over happiness, but it seems to me that the Napier and Jost paper is an example of trying to explain away an unpalatable truth. It's better to dig deeper to understand the causes of these differences before offering public policy prescriptions (or even arguments for what is individually better to do). Wilkinson, who has done extensive review of the literature on happiness and proposed public policy prescriptions, seems to me to have the better psychological explanation for the happiness difference in terms of sense of control over outcomes. That explanation also comports well with a charitability difference--if you don't feel that your contribution could make much difference, you're probably less likely to make a contribution.

A measure for crackpots

Last night at a party, a few of us were discussing some recent self-published books by crackpots that we've seen or had pushed on us. We noted that these books seem to have in common a few features. They seem to often have long rambling introductions that are missing key elements like thesis statements or an indication of what the book is about. They use words in non-standard ways, yet don't bother to explain how they are being redefined. They claim that the author has some special knowledge, yet don't provide any reason to believe it is the case.

I had a dim recollection of having come across a "crackpot index" before somewhere, and a little bit of searching yielded Fred J. Gruenberger's December 1962 publication from the RAND Corporation titled "A Measure for Crackpots" (PDF), which offers the following scoring mechanism for distinguishing the scientist from the crackpot:

1. Public verifiability (12 points)
Scientists promote public verifiability; crackpots rely on revealed truth.

2. Predictability (12 points)
Scientists promote predictability and track their record of failure as well as success; crackpots promote wild predictions and count only successes, not failures.

3. Controlled experiments (13 points)
Scientists promote controlled experiments; crackpots avoid them.

4. Occam's razor (5 points)
Scientists prefer the simplest explanation that covers all the facts; crackpots enjoy wildly complex theories.

5. Fruitfulness (10 points)
Scientists prefer theories that generate new ideas and new experiments; crackpots prefer theories that produce nothing of value for further research.

6. Authority (10 points)
Scientists seek the endorsement and validation of known authorities and tend to obtain it if their work is valid; crackpots usually fail to obtain it.

7. Ability to communicate (8 points)
Scientists tend to promote clear (if sometimes dull) communications through approved channels; crackpots tend to be incomprehensible and self-published.

8. Humility (5 points)
Humility is a desirable (if sometimes lacking) trait in scientists; it is rare in the crackpot.

9. Open mindedness (5 points)
Scientists tend to qualify and carefully couch their statements as tentative based on the current evidence; crackpots tend to make absolutely certain statements that may not be challenged.

10. The Fulton non sequitur (5 points)
I'm more familiar with this as the "Galileo Gambit," or the common crackpot claim that "They laughed at Galileo; they're laughing at me; therefore I'm right just as Galileo was." Gruenberger uses steamboat inventor Robert Fulton in place of Galileo. This logically invalid argument is refuted by the Bozo rejoinder, which is that "they also laughed at Bozo the clown." This is a negative test, lack of the characteristic is 5 points, presence is 0.

11. Paranoia (5 points)
Another negative test--crackpots tend to be paranoid about their ideas being actively suppressed by conspiracy.

12. The dollar complex (5 points)
Another negative test. The crackpot claims immeasurable value for his discoveries as revolutionary, worthy of the Nobel prize, and world-changing.

13. Statistics compulsion (5 points)
The crackpot tends to use and continuously explain statistics allegedly supporting his claim, while the scientist tends to use standard methods and assume the reader is familiar with them.

Gruenberger's index is focused on science crackpots rather than philosophy crackpots, but a number of the above features do apply to the books we were talking about.

A more recent "Crackpot Index," also focused on physics, was created by John Baez, a mathematical physicist at the University of California, Riverside:

A simple method for rating potentially revolutionary contributions to physics:

A -5 point starting credit.

  1. 1 point for every statement that is widely agreed on to be false.
  2. 2 points for every statement that is clearly vacuous.
  3. 3 points for every statement that is logically inconsistent.
  4. 5 points for each such statement that is adhered to despite careful correction.
  5. 5 points for using a thought experiment that contradicts the results of a widely accepted real experiment.
  6. 5 points for each word in all capital letters (except for those with defective keyboards).
  7. 5 points for each mention of "Einstien", "Hawkins" or "Feynmann".
  8. 10 points for each claim that quantum mechanics is fundamentally misguided (without good evidence).
  9. 10 points for pointing out that you have gone to school, as if this were evidence of sanity.
  10. 10 points for beginning the description of your theory by saying how long you have been working on it.
  11. 10 points for mailing your theory to someone you don't know personally and asking them not to tell anyone else about it, for fear that your ideas will be stolen.
  12. 10 points for offering prize money to anyone who proves and/or finds any flaws in your theory.
  13. 10 points for each new term you invent and use without properly defining it.
  14. 10 points for each statement along the lines of "I'm not good at math, but my theory is conceptually right, so all I need is for someone to express it in terms of equations".
  15. 10 points for arguing that a current well-established theory is "only a theory", as if this were somehow a point against it.
  16. 10 points for arguing that while a current well-established theory predicts phenomena correctly, it doesn't explain "why" they occur, or fails to provide a "mechanism".
  17. 10 points for each favorable comparison of yourself to Einstein, or claim that special or general relativity are fundamentally misguided (without good evidence).
  18. 10 points for claiming that your work is on the cutting edge of a "paradigm shift".
  19. 20 points for emailing me and complaining about the crackpot index, e.g. saying that it "suppresses original thinkers" or saying that I misspelled "Einstein" in item 8.
  20. 20 points for suggesting that you deserve a Nobel prize.
  21. 20 points for each favorable comparison of yourself to Newton or claim that classical mechanics is fundamentally misguided (without good evidence).
  22. 20 points for every use of science fiction works or myths as if they were fact.
  23. 20 points for defending yourself by bringing up (real or imagined) ridicule accorded to your past theories.
  24. 20 points for each use of the phrase "hidebound reactionary".
  25. 20 points for each use of the phrase "self-appointed defender of the orthodoxy".
  26. 30 points for suggesting that a famous figure secretly disbelieved in a theory which he or she publicly supported. (E.g., that Feynman was a closet opponent of special relativity, as deduced by reading between the lines in his freshman physics textbooks.)
  27. 30 points for suggesting that Einstein, in his later years, was groping his way towards the ideas you now advocate.
  28. 30 points for claiming that your theories were developed by an extraterrestrial civilization (without good evidence).
  29. 30 points for allusions to a delay in your work while you spent time in an asylum, or references to the psychiatrist who tried to talk you out of your theory.
  30. 40 points for comparing those who argue against your ideas to Nazis, stormtroopers, or brownshirts.
  31. 40 points for claiming that the "scientific establishment" is engaged in a "conspiracy" to prevent your work from gaining its well-deserved fame, or suchlike.
  32. 40 points for comparing yourself to Galileo, suggesting that a modern-day Inquisition is hard at work on your case, and so on.
  33. 40 points for claiming that when your theory is finally appreciated, present-day science will be seen for the sham it truly is. (30 more points for fantasizing about show trials in which scientists who mocked your theories will be forced to recant.)
  34. 50 points for claiming you have a revolutionary theory but giving no concrete testable predictions.
    Here's a nice crackpot response to that index.

    Atheism and the difference between consistency and entailment

    A Christian rural psychologist has posted on his blog about "some psychological aspects of atheism," where he claims that:
    [Atheists] tend to not be able to understand that their position means “anything goes,” with respect to morality. If there is no God, then there is no objective thing as morality. It’s all subjective… They always find some way to justify the fact that they practice at least some moral principles. Whether they think it’s biologically ingrained through millions of years of evolution or morality is simply “adaptive in allowing the species to survive.” Most often; however, they have never even considered the logical consequences of atheism and morality.
    He also engages in some armchair theorizing about atheism being caused by absent fathers, being intolerant, etc., all without any reference to empirical evidence. (And given the recent Pew Forum survey results where one in five self-reported "atheists" say that they believe in God or a higher power, I think any study of atheists needs to make sure that it's dealing with people who actually know what the word means.)

    But the quoted passage is completely off-base. Atheism is a denial of the existence of gods. That entails the falsity of divine command theory as a basis for morality, but not much else. Most philosophers have rejected divine command theory as an adequate basis for morality since Plato wrote the "Euthyphro" and asked the critical question, "is the pious [or right] loved by the gods because it is pious [right], or is it pious [right] because it is loved by the gods"? Either fork of the dilemma leads to bad consequences--if the former, then there must be some other ground for moral rightness than because the gods will it to be so, and so the gods themselves are unnecessary. If the latter, then the gods could make acts that we consider to be clearly immoral into right actions according to whim. The latter seems more consistent with the morality of the Bible, since God is depicted therein as commanding murderous acts including the killing of women and children, but it is simply a "might makes right" philosophy of morality. But I think the former is clearly the right horn of the dilemma to grasp--morality is not something which requires gods.

    Now, there are certainly atheist philosophers who have argued that atheism precludes more than the divine command theory. The atheist philosopher J.L. Mackie, in his book Ethics: Inventing Right and Wrong, argues against morality being objective properties of the world on the basis of their "queerness." And I think he is probably right at least to the extent that moral properties are not human-independent properties. My view is that there are certain basic values, held by most human beings and evolutionary in origin, essential to social organization and beneficial to our survival and thriving, which objectively entail moral consequences for us, composed as we are and in the environment (physical and social) we find ourselves in.

    But my view is not important for confronting the claim of the quoted passage. All atheism means is the denial of the existence of gods. It is not a complete worldview, it is simply a single component in an infinite number of possible consistent worldviews. An atheist can, like J. M. E. McTaggart, believe in reincarnation and immortality. An atheist can believe in the paranormal, in ghosts, in supernatural beings other than gods. An atheist can be a nihilist, a relativist, a utilitarian, a contractarian, an existentialist. An atheist can be a conservative, a liberal, a socialist, an anarchist, a monarchist, a libertarian, a Marxist, or hold any other possible view of political philosophy that doesn't entail the existence of gods. All of these views are consistent with atheism, meaning simply that no contradiction is produced by the combination of the views.

    Amorality and nihilism are consistent with atheism--it is certainly possible for an atheist to hold that there are no moral truths, that there is no difference between right and wrong. But mere consistency is not the same as entailment--it does not follow that if you are an atheist, it logically follows or is necessary to hold such views. Yet that's what the quoted author is falsely claiming to be the case.

    Note that amorality and nihilism are also consistent with theism--and in my opinion, both are possible for theists whichever horn of the Euthyphro dilemma is grasped. If the ground of what is morally right is something independent of the gods that does not exist, even while gods do, then that's an amoral theism. And if all there is to morality is what the gods will it to be, that makes morality dependent upon the values of the gods--if the gods choose to be amoral or nihilists, then again there's amoral theism.

    The Christian psychologist goes on to write (citing this very blog for the quote):
    Now, I have only seen or read about one logically consistent atheist…..Jeffrey Dahmer. There have been philosophers, I know, who have come to this logical conclusion. But I’m talking about someone who logically practiced what he believed.
    “If a person doesn’t think there is a God to be accountable to, then—then what’s the point of trying to modify your behaviour to keep it within acceptable ranges? That’s how I thought anyway. I always believed the theory of evolution as truth, that we all just came from the slime. When we, when we died, you know, that was it, there is nothing…” (1)
    So said Dahmer.
    The "what's the point" question is easy to answer--there are clearly consequences for us to our own behavior regardless of any accountability to God. Sane, rational people desire to live good and happy lives, rather than follow the example of Dahmer. Even leaving God out of the picture, where is the slightest appeal in following Dahmer as a model of rational living? I see none.

    But the position this psychologist takes opens up an obvious question that he doesn't notice--God isn't accountable to anyone. Why should God be good, instead of acting maliciously, callously, and evilly, in the absence of any accountability to anyone? According to this psychologist, the answer should be that God should rationally act as an omnipotent Jeffrey Dahmer. Having no greater God to hold him responsible, he should not be bound to any code of morality, his word should be valueless, and every action based on the whims of the moment without regard to any future consequences.

    That should be considered a reductio ad absurdum of his position. Either there are rational reasons to not act like Jeffrey Dahmer independently of being held accountable to a higher being, or God behaves irrationally by not acting like Jeffrey Dahmer. (Or perhaps, given the content of the Old Testament, God does act like Jeffrey Dahmer.)

    UPDATE: I've engaged in further argument with the psychologist in the comments of his blog, as have others.

    UPDATE: After a few back-and-forth exchanges, I don't think the psychologist means to talk about logical consequences of beliefs. I think probably the best reconstruction of his actual argument is something like this:

    1. Human beings find it psychologically necessary to believe in an objective external source of morality. (In order to be happy, function well psychologically, etc.)
    2. Atheism doesn't provide such a source by itself.
    3. Those whose worldview is composed entirely of atheism, without augmenting it with some objective external source of morality, have no psychological reasons to act in moral ways.

    This is a much more plausible argument. He says something very much like (3), and goes on to say something to the effect that none of these substitutes are sufficient, and his reason seems to be along the lines that people's choices for these substitutes are arbitrary or that they are not externally imposed. But his reasoning is faulty--the fact that people choose for themselves doesn't mean that their choices are arbitrary (they can have good reasons), and external imposition seems to be irrelevant. Presumably he would agree that someone who converts to Christianity as an adult can have all of the psychological benefits he's claiming for theism. And what of the thousands of other religions, sects, and interpretations that can be acquired from one's parents or others? His argument doesn't have any way of singling out Christianity (or any particular version thereof) as special in this regard. It seems to me that it really comes down to an argument about the social and psychological benefits of adopting the beliefs of one's culture that most people accept--though I'm sure he doesn't want to accept the cultural relativism that seems to me to be implied by his position.

    UPDATE: The "Country Shrink" has resorted to "let's agree to disagree" without even attempting to respond to the criticism of his claim that morality requires theism, nor has he responded to my attempted reformulation. Instead, he has asked whether my impressions of atheists differ from him--claiming the moral high ground, intellectual superiority, etc., to which I responded that I see that as most prevalent among atheists who were previously evangelical Christians, and that he's likely attributing causes to the wrong place. I don't think it's caused by atheism as much as by reaction to Christianity.

    UPDATE (July 6, 2008): The "Country Shrink" has made a followup post in which he takes a stab of sorts at addressing some of the philosophical arguments I made, but mostly by engaging in argument from ignorance and attempting to shift the burden of proof to me, even though he is the one maintaining that it is impossible for there to be any objective meta-ethical framework without gods. He also asserts (rather than argues) that incompatibilism is the correct position in the free will debate and that consciousness cannot be explained naturalistically. I don't discern any actual arguments for either of those positions other than failure of imagination.

    The Amazing Meeting 6 summarized, part three

    This is part three of my summary of The Amazing Meeting 6 (intro, part one, part two, part four, part five).

    Friday night was my one late night out, as I went with a group of Denver and Boston skeptics (and one local friend) to Gallagher's Steakhouse at the New York, New York Casino. On the walk down the strip, we passed some 9/11 truthers holding signs promoting a website promoting their views. I told one that he should check out 911myths.com, to which he responded, "That's funny." He ended up going off on a rant about how I was sticking my head in the sand, to which Iunproductively responded in an off-color manner about where he was sticking his head. We had a fantastic, though expensive, meal, and I ended up leaving my camera at the restaurant. Fortunately, I was able to retrieve it even though the restaurant had closed.

    Saturday morning I had breakfast with an attorney from Florida and a regular attendee of hacker's conferences from Pennsylvania; we talked a bit about criminal hacking on the Internet and copyright law.

    Michael Shermer on the Skeptologists and why people believe in unseen things
    Michael Shermer gave the first talk of the day. He began by talking about how he recently accepted some money from the Templeton Foundation in return for editing a booklet of thirteen essays on the question "Does science make belief in God obsolete?", which he agreed to do on the condition that he could pick at least some of the people to write answers to the question. Respondents included Kenneth Miller, Victor Stenger, Christopher Hitchens, Stephen Pinker, and Stuart Kauffman.

    He then showed a segment from a TV show pilot, "The Skeptologists," that is now being pitched to the TV networks. The show features Yau-Man Chan, Mark Edward, Steven Novella, Phil Plait, Kirsten Sanford, Michael Shermer, and Brian Dunning investigating claims using the tools of skepticism. The segment shown was of Shermer, Sanford, and Novella investigating health claims made for wheat grass, such as that because it contains chlorophyll which is molecularly similar to hemoglobin, it turns into hemoglobin when you consume it.

    Shermer then went on to give a talk about "why people believe in unseen things," arguing that we engage in learning by association (something illustrated by Banachek's memory workshop) and have a tendency to make type II errors (incorrectly accepting a belief in something false) over type I errors (incorrectly rejecting a belief in something true). He gave a brief review of some evidence that when we process a sentence in order to understand it, we go through the same steps as entertaining that it is true, and to exercise skepticism about it requires additional effort; disbelief requires a subsequent process of rejection after the process of comprehension. This kind of acceptance of knowledge presented by others makes sense for a child growing up, especially in a hostile environment where survival is at stake.

    Humans also tend not to be persuaded by or even remember being told that something is false--the negation can be forgotten while the statement being denied is remembered as true. A flyer put out by the CDC to rebut myths about flu vaccines turned out to have the opposite of the desired effect, at least by certain groups of people--after 30 minutes, they remembered 28% of the false statements as being true, and after three days the percentage jumped to 40%. (Also see Sam Wang and Sandra Amodt's op-ed in the June 27, 2008 New York Times, "Your Brain Lies to You.")

    Shermer didn't mention the study I've linked to, but rather later near the end of his talk referred to some fMRI studies by Sam Harris, Sameer Sheth, and Mark Cohen (PDF) about evaluating statements as true, false, or undecideable, comparing reaction times to different types of statements.

    Agency and the intentional stance
    Shermer talked about the work of Pascal Boyer and Daniel Dennett on agency and the intentional stance--that we tend to assume by default that everything that happens not only has a cause, but is caused by an agent, and particularly one that means us harm. Such an assumption may make evolutionary sense to enable survival, though it clearly doesn't work well for accurate explanations of the world. But such appeal of agency lies behind intelligent design theory, and attributing supernatural intentions to natural phenomena. Shermer called this "The God Illusion" rather than "delusion," because he, like Boyer and Dennett, see it as a normal cognitive illusion rather than something delusional or pathological.

    He went on to talk about folk intuitions as being the engines of all sorts of beliefs. He gave examples from folk astronomy, folk biology (the elan vital), folk psychology (mind/brain dualism), and folk economics (centrally planned economies). He compared natural selection and Adam Smith's invisible hand, observing that many people misconstrue one or the other as being something magical or directed. He observed that we have folk intuitions that have evolved for a particular environment, yet do not work well at the huge or tiny scales.

    Then, more controversially, he referred to folk politics, viewing societies as an extension of the family, and referred to "intelligent government theory," the "God of the government" theory, and "the government illusion," drawing an analogy to intelligent design, God of the gaps, and the God illusion, respectively. But where intelligent design says "I can't imagine how X could have evolved, therefore it must have been designed," he described "intelligent government theory" as based on the faulty reasoning that "I can't imagine how X could be done privately, therefore a government must do it." The difference here, as I've already mentioned, is that we know that governments exist and do provide services. The libertarian argument about private provision of services vs. government provision of services is one about whether government is necessary, or moral, or more efficient than private provision of services. To my mind, such arguments are well worth having, but come down to questions of competing values (e.g., liberty vs. justice) and empirical evidence about costs and benefits of competing approaches. It's not really analogous to the question of the existence or nonexistence of gods, unless perhaps one takes that to partly be an issue about the pragmatic value of belief in an illusion vs. truth.

    Sharon Begley
    Newsweek science writer Sharon Begley gave a talk titled "Creationism and Other Weird Beliefs: The Role of the Press," with a subtitle "hint: don't get your hopes up." She was very pessimistic about the press being helpful in promoting critical thinking. She began by telling the story of the Tichbourne Claimant. In 1854, Roger Tichbourne was lost at sea off the coast of Brazil. He had been raised in France to the age of 16, then in England. He was very thin, and had blue eyes and tattoos. His mother refused to accept that he was dead, and placed ads in newspapers seeking him. Some 20 years later, a man from Wagga Wagga, Australia contacted her, claiming that he had not previously contacted her because he wanted to achieve success on his own accord, under the name "Mr. Castro," but had failed to do so. This man, the Tichbourne Claimant, was obese, spoke no French, had no tattoos, had brown eyes, and was an inch taller than Roger Tichbourne, yet she accepted him as the genuine article.

    According to Begley, the role of the newspaper is not to educate. In the early years of the AIDS crisis, public health officials asked for the press to run informative stories, and they complied, but this was not helpful because:
    • The scientific ignorance of the American public.
    • The capacity for rational thnking is not identical to the disposition to employ rational thinking.
    • There is a disconnect between factual knowledge and belief, as exhibited in the case of Mrs. Tichbourne.
    • Public attitudes towards the press are negative.
    • The press has a commitment to "balance."
    • Common sense is not common.
    She gave some statistics on polls of Americans' agreement or disagreement with the statement that "Human beings as we know them developed from earlier species of animals":

    1985: 45% agreed, 48% disagreed, 7% unsure.
    2005: 40% agreed, 39% disagreed, 21% unsure.

    By comparison the percentage of agreement in Iceland, Denmark, and Sweden was over 80%; of OECD nations only Turkey had a lower percentage of acceptance than the U.S.

    Evolution, gay marriage, and abortion are all highly politicized in the U.S. in a way that they aren't in Europe or Japan.

    But if the question was "Can natural selection explain appearance and change over time of animals," 78% of Americans agreed. Yet 62% agree that "God created humans as they are today." This, according to Begley, is because Americans have a view of human exceptionalism.

    She went through a list of facts that are beyond dispute, which were presented to Americans for acceptance or denial. Two examples:

    More than half of all genes in humans are identical to those in mice. 33% agree
    More than half of all genes in humans are identical to those in chimps. 38% agree

    Only 9% of Americans know what a molecule is. Because of this, while sports writers can use abbreviations such as ERA and RBI without explaining them, Begley says she cannot assume her readers know anything at all, and recently learned that she can't even refer to DNA and expect her readers to know what she's talking about.

    She observed that a disposition to critical thinking is associated with being more curious, open-minded, open to new experiences, conscientiousness, being less dogmatic, less close-minded, less authoritarian, and likely to rely more on epirical and rational data than on intution and emotion when weighing information and reaching conclusions. But you have to both have the skills and want to think critically in order to apply them. In addition to Tichbourne as an example of someone who had the skills but didn't want to apply them, she noted that Sir Arthur Conan Doyle's son was killed two weeks before the end of WWI, and he went to a medium who claimed to contact his son, which he very much wanted to believe. Alfred Russell Wallace, who formulated evolution by natural selection parallel to Darwin, was also a believer in ghosts, levitation, spirit photography, and clairvoyance. And she noted that a statement Penn Jillette made the previous day sounded like he was rejecting climate change on the basis of a dislike for Al Gore. (UPDATE, July 4, 2008: Sharon Begley wrote about this at the Newsweek blog, and Penn Jillette responded in the Los Angeles Times. I think Penn more accurately reports what happened than Sharon Begley did--he really did say that he didn't know, and that people he knows and considers reliable tell him that anthropogenic climate change is real. One thing Penn gets wrong is that Teller didn't mention Gore's name when he said that carbon credits are "bullshit modeled on indulgences.")

    She commented on some of the negative letters she has received any time she writes about evolution or critically about claims like alien abductions. When she wrote an article for the Wall Street Journal about the discovery of Tiktaalik, she received several letters which she read excerpts of, three examples of which were the standard argument that "evolution requires more faith" than believing that God did it, a letter asking "where are the billions of 'transition fossils,'" and one asking, "if you are terminal will you call on Darwin or God?"

    Don't count on the press
    The "reality-based community" must contend with contrarian politicians, the masses' distrust of elites, and new sources of news. With regard to the last point, she pointed out that Googling evolutionary biology terms often brings up Answers in Genesis sites prior to sites with accurate information.

    The journalistic conceit of objectivity, she said, is imported from political disputes where there are two contrary sides. (I actually think that notion of balance is as often mistaken in politics as it is in science--there may only be one side with any valid support, or there may be more than two sides deserving of representation, though the latter is more common in politics than in science. But dualism is a misrepresentation in both circumstances.)

    Uncommon common sense
    Begley made the following points, which had some overlap with Shermer's talk:
    • Evolution is not intuitive.
    • Common sense can mislead us about the physical world.
    • Our brains are driven to see patterns.
    • We have a habit of imputing consciousness to inanimate objects.
    • Someone is staring at me from behind. (People tend to have and respond to such feelings. I can't remember if she actually discussed Rupert Sheldrake's studies of this, or of the skeptical critiques by Robert Baker or Richard Wiseman.)
    She gave the example of an experiment with a sweater at Bristol University. Students were shown a ratty old sweater and asked who would be willing to put it on in return for a payment of twenty British pounds. Most indicated a willingness to do so. But if they were then told, oh, by the way, this sweater belonged to a murderer, many of the hands would go down--as though evil were a property that contaminated the object. What she didn't mention is that similarly, the value of something associated with someone of status has the reverse effect--e.g., if the sweater were claimed to belong to Einstein. The effect of status on objects is one that is clearly prevalent even among skeptics, who are as likely as anyone to enjoy collecting autographs and memorabilia, or objects like ping pong balls used on a television show (see Adam Savage's talk, below).

    Derek and Swoopy
    Derek and Swoopy, the hosts of the official Skeptics Society podcast, "Skepticality," gave a short talk about their show and noted that they now have about 35,000 listeners per program, and that the top two skeptics' podcasts, "Skepticality" and "The Skeptics Guide to the Universe," have over 4 million downloads between them. They reported that after some successful skeptical panels at science fiction conventions, Dragon*Con 2008 in Atlanta this Labor Day weekend, a conference so large that it occurs at four hotels, will have four full days of skeptical content, a "Skeptrack" featuring James Randi, Michael Shermer, Phil Plait, Ben Radford, Alison Smith, George Hrab, and others.

    Steven Novella
    Dr. Novella gave a talk on "Dualism and Creationism" covering the history of dualism in philosophy of mind, evidence from neuroscience, and a discussion of modern dualism. In his discussion of dualism in philosophy, he attributed to Descartes a notion of computation occurring in the brain and a position he called "consciousness dualism." I think perhaps that gives Descartes too much credit, though he did think that "animal spirits" flowing in the brain caused signals from perception to be projected on the surface of the pineal gland, which was the seat of the soul and consciousness.

    He referred to the advocacy of property dualism/epiphenomenalism by David Chalmers, and observed that his views would not be acceptable to most of those who advocate dualism. Chalmers's position is that most mental activity is physical brain activity, but there's a remaining hard problem of consciousness posed by the conscious properties of perception and feeling known as qualia, which distinguish unconscious zombies that could behave just like us from real people. He gave Deepak Chopra as an example of an individual who is essentially a denialist about contemporary neuroscience, an anti-materialist who supports "quantum woo," Eastern mysticism, and what he called "substrate consciousness," a feature of the universe itself.

    Evidence from neuroscience
    Novella gave the following points to summarize the evidence from neuroscience:
    • Brain anatomy and activity correlates with mental activity.
    • There is no mind without the brain.
    • Brain development correlates with mental development.
    • If you damage the brain, you damage the mind.
    • Different states of consciousness correlate with different brain states.
    • Turn off the brain and you turn off the mind.
    • The mind does not survive the death of the brain.
    • MEG (magnetoencephalography) can be used to provoke specific mental effects, including inducing out-of-body experiences at will.
    My notes on the last point suggest that Novella said that MEG could be used to induce OBEs. There were a couple of recent studies about two different methods for inducing OBEs, but I don't recall either of them using magnetic induction (e.g., this 2007 Science paper). I'm skeptical of Michael Persinger's claims of magnetic induction of religious experiences (also see this 2004 Nature article).

    We're in the process of reverse-engineering the brain, and the materialist model of consciousness is working pretty well. The elements of consciousness are increasingly identifiable and localizable, and our ability to reconstruct them in artificial intelligence will be the ultimate test.

    Novella defined consciousness as the moment-to-moment functions of the brain, when it is processing information reflectively, and presenting it to the part of the brain that is paying attention. (Is it really commonly accepted that attention is localized to a particular part of the brain?) We are trying to assess our consciousness with our consciousness.

    The vitalism analogy
    Novella stated, referencing Daniel Dennett, that just as life is an emergent property of living things, consciousness is the sum of the easy problems about consciousness, leaving no remaining residue of a hard problem, just as there is no elan vital for biology.

    Egnorance
    Novella then talked about neurosurgeon Michael Egnor, who he said makes the mistake of confusing the question of "does" with "how." That is, because we don't know the details of how consciousness is physically generated, it must not be the case. He compared this to the "God of the gaps" argument--whatever is currently unexplained must be caused by something supernatural.

    Defenses of dualism
    Novella then went through a few rhetorical strategies used to defend dualism. One is that any day now, evolution (or materialism) will collapse. But they've been saying this in the evolution case for 100 years. (Glenn Morton has a nice article titled "The Imminent Demise of Evolution: The Longest Running Falsehood in Creationism," which offers 178 years of such quotes.)

    Another is to generate false controversy, and say that until the argument is resolved, it's legitimate to accept dualism.

    Then there's the claim of impending acceptance, the converse of the imminent demise argument--that Deepak Chopra's views are about to be accepted by the entire world, for example.

    The need to change science--Novella said that B. Alan Wallace, a Buddhist, has argued that we need to reintroduce subjective evidence into science. Novella suggested that subjective evidence can't be scientific evidence, which I think is a slight overstatement--a self report is a valid source of data, we just need to have a way to correlate those self reports with other evidence.

    In his conclusion, Novella stated that the purpose of modern Cartesian dualism is to provide intellectual cover for a belief system--presumably including various religious views about immortality as well as Deepak Chopra's views.

    It's worth noting that Keith Augustine of the Internet Infidels has done a lot of work presenting the evidence against survival of death and the possibility of immortality, as well as critical of claims that near-death experiences are evidence of survival. He has recently published a four-part series of articles in the Journal of Near-Death Studies on the subject, which have been accompanied by responses from NDE researchers. He is also working on an anthology which will respond to recent arguments for dualism. I urge Novella to contact Augustine, as he might have some contribution to make to that anthology.

    Jeff Wagg
    Jeff Wagg of JREF stated that there is a possibility of a future TAM in the UK, and that TAM7 will be in Las Vegas on July 9-12, 2009 at the South Point Casino. There will also be a JREF Mexican Riviera cruise in March, 2009, which still is looking for speakers.

    Jim Underdown
    Jim Underdown of the Center for Inquiry, Los Angeles reported that the Independent Investigations Group, a skeptical group that does paranormal investigations, would be giving an award for best TV show or movie that debunks pseudoscience to Penn & Teller's Bullshit!, and a lifetime achievement award to James Randi.

    Randi came up and said that some years ago he had terminated his relationship with CSICOP because they had asked him to stop going after Uri Geller, who was suing him repeatedly (and had also sued CSICOP as a result). Randi said that Geller only won once, in the Japan case, where the judgment was lowered from slander to insult, and that while Geller was suing for millions he was only awarded a small amount. The amount was 500,000 yen against Randi, and a larger amount against the Japanese magazine which reported Randi's erroneous statement that Dr. Wilbur Franklin of Kent State University had killed himself after Randi discredited Geller, who Franklin had endorsed as genuine. Franklin had actually died of natural causes, and Randi attributed the Japanese magazine statement to a mistranslation of the phrase "shot himself in the foot," though Randi had been quoted in a U.S. publication in English making the same statement about Franklin killing himself out of embarrassment over Geller's exposure. Geller also won a case in Hungary for a statement by Randi that called Geller a swindler, though Randi was not named in that suit. After Geller sued Victor Stenger in Hawaii, CSICOP and Prometheus in England, and CSICOP and Prometheus in Miami, Prometheus Books added errata slips to Stenger's Physics and Psychics and to Randi's The Truth About Uri Geller regarding an incident where Geller was sued in Israel for breach of contract and not, as those two sources stated (Stenger relying upon Randi), "arrested." The Miami suit was eventually won by Prometheus and CSICOP on the grounds that Geller had knowingly filed after the statute of limitations had expired, and Geller paid them slightly less than half of the fees, costs and sanctions that were originally awarded and dismissed his appeal. Contrary to the impression Randi has sometimes given, the vast majority of Geller's lawsuits were not about paranormal abilities, but about accusations of other kinds of impropriety, such as fraud, criminal acts, plagiarism, and so forth. Geller gives his version of events on his web page.

    Now, apparently as a result of this award, Randi said he would like to forgive and forget, and resume his relationship with CSICOP (now CSI).

    The Skeptologists
    During lunch was a showing of the full pilot episode of "The Skeptologists," which also included a segment on the tools used for ghost hunting, testing them aboard the Queen Mary in order to see what they actually measure. I missed all but the ending, but it was shown again on Sunday, about which more later.

    There were several more speakers on Saturday--Phil Plait, Adam Savage, Matthew Chapman, Richard Wiseman, and a panel discussion ostensibly on "the limits of skepticism," but I'll save that for further summary tomorrow.

    On to TAM6 summary, part four.

    Liberaltarianism

    Will Wilkinson has an interesting post about how his market liberal views are very like the views of Hayek, Friedman, and Buchanan, and that the libertarian-conservative alliance against a slippery slope to socialism isn't justified by what's actually occurring in the world today.

    In a subsequent post, he writes about how economic regulation and tax/transfer policies are logically separable, but most people think about them as if they aren't; a comparison of levels of inequality and poverty across the EU shows that the common thought that less regulation and taxation goes hand-in-hand with higher levels of poverty and inequality (of the sort seen in the U.S. and UK) doesn't hold. Thus you could have a regime with very low levels of regulation yielding more wealth, combined with more redistribution for a better safety net and less poverty and inequality.

    And in another post, he calls for greater empirical grounding for proposals in political philosophy, of the sort that has started to yield fruitful results in moral philosophy:
    But shouldn’t it impossible to take seriously an argument to the effect that, say this or that policy is required in order to secure the conditions for the development of some capacity, in the absence of (a) a well-empirically-grounded theory of the nature of that capacity and its development, and (b) some kind of actual evidence that this or that policy in fact has the kind of effect on it that one hypothesizes? I wouldn’t mind so much if political philosophy arguments were more often in the form of “Hey, here’s a conjecture! I suggest somebody competent to do so try to find out if it’s true.” I would be quite happy if I saw more “Hey, here’s a conjecture, and here’s a my attempt to honestly synthesize the relevant literature in a first pass at getting the answer.” That would be terrific. But usually, the argument aims to establish something substantive with an armchair, a Joe Stiglitz op-ed, and something remembered from the Tuesday Science Times.
    Let's hear it for empiricism.

    Ben Stein thinks science leads to killing people

    In an interview in Christianity Today:
    I believe God created the heavens and the earth, and it doesn’t scare me when scientists say that can’t be proved. I couldn’t give a [profanity] whether a person calls himself a scientist. Science has covered itself with glory, morally, in my time. Scientists were the people in Germany telling Hitler that it was a good idea to kill all the Jews. Scientists told Stalin it was a good idea to wipe out the middle-class peasants. Scientists told Mao Tse-Tung it was fine to kill 50,000,000 people in order to further the revolution.
    In an interview on the Trinity Broadcasting Network with Paul Crouch, Jr. (video is available if you follow the link):
    Stein: When we just saw that man, I think it was Mr. Myers [i.e. biologist P.Z. Myers], talking about how great scientists were, I was thinking to myself the last time any of my relatives saw scientists telling them what to do they were telling them to go to the showers to get gassed … that was horrifying beyond words, and that’s where science — in my opinion, this is just an opinion — that’s where science leads you.

    Crouch: That’s right.

    Stein: …Love of God and compassion and empathy leads you to a very glorious place, and science leads you to killing people.

    Crouch: Good word, good word.
    Note that he offers no qualifiers. He doesn't say science must be complemented with ethics. He doesn't say that science (like any knowledge of truths about the universe) may have negative as well as positive consequences. He simply says that science leads to mass murder.

    If Stein really believes this, then he must be a genuine opponent of the practice of science, and his promotion of "Expelled" can be seen as an aspect of that anti-scientific attitude, despite the fact that he certainly takes personal advantage of many of the positive contributions of science. If he doesn't genuinely believe it, then he's not only engaging in a defamatory slur against scientists, he's also dishonest.

    Either way, he's demonstrated that he is a despicable character.

    And some people claim not to understand why scientists are angered by this film and its creators.

    Larry Moran at The Sandwalk

    David Berlinski, King of Poseurs

    Jeff Shallit talks about Discovery Institute Fellow David Berlinski, notable as one of the few advocates of intelligent design who is not an evangelical Christian. He's also not a scientist or a mathematician; he has a Ph.D. in philosophy from Princeton. Although that's a top school for philosophy in the U.S., Berlinski hasn't been working as a professional philosopher, either.

    Of course, he was touted as an expert in "Expelled."

    An argument in support of Matt Nisbet

    I thought I'd try to come up with an argument *for* Nisbet's general position (though I don't support the claims that all publicity is good publicity or that particular people should shut up), and came up with this (posted as a comment on Nisbet's blog):

    Suppose U.S. demographics on belief and nonbelief were reversed, so that atheists made up 80%+ and those who explicitly believed in God were about 4-5% of the population (with the difference filled by agnostics, closeted believers, etc.). Suppose further that demographics of believers in science were reversed--with most physicists and biologists being religious believers, who commonly said things like "the Big Bang shows evidence of a beginning of time, started by a creator God," and "the intricate design of biology shows the hand of God."

    Presumably Nisbet would tell those religious scientists that they shouldn't say things like that in public, even if they firmly believe them to be true, because they would cause the atheist majority to stop listening to the part that's actually science. And I think he'd have a point. To the extent that Dawkins and Myers go beyond the science into areas like philosophy and normative ethics, they are making non-scientific claims that are not entailed by the scientific evidence (though I happen to agree with them that atheistic views fit much better with the evidence than religious views). A division *can* be drawn, and if your goal is persuasion, *somebody* needs to draw the division and communicate with the audience that otherwise wouldn't listen without including the nonscientific parts that will turn them off.

    But, contra Nisbet, that somebody doesn't need to be everybody, or Dawkins or Myers in particular.

    As I've said elsewhere, I'm glad that the National Center for Science Education doesn't take a position on theism vs. atheism and involves many religious believers who support the promotion of good science.

    Matt Nisbet and Chris Mooney have been getting support in their statements from people like intelligent design advocate William Dembski and "Expelled" co-writer Kevin Miller, but I suspect that they would not really agree with Nisbet's position if the demographics were reversed as above--they would be defenders of the religious version of P.Z. Myers. Their position strikes me as opportunistic rather than principled.

    Which raises the question--if you support P.Z. Myers' approach and think that it's beneficial for the promotion of science, but you wouldn't support a religious counterpart's approach in the reversal scenario, does that show an inconsistency or lack of principle in your position? I don't think so, and my parenthetical comment is a start of the answer I'd give to why. (I think the underlying causes of the demographics are of relevance, and it's interesting that only Nisbet seems to have tackled that subject in this discussion.) But I'm interested in hearing what others have to say, either way. I suspect that John Lynch and John Wilkins would argue that it does show an inconsistency.

    UPDATE (April 2, 2008): James Hrynyshyn at The Island of Doubt ScienceBlog offers a critique of Nisbettian framing. Somehow, I get the impression something's missing here, though. Claiming that scientists are completely objective and trained to be so is to miss the fact that Kuhn, Latour and Woolgar, and the sociologists of science aren't completely wrong about everything. (I'm still a big fan of Philip Kitcher's book, The Advancement of Science: Science Without Legend, Objectivity Without Illusions.)

    UPDATE (April 3, 2008): John Wilkins offers a defense of "the f-word" in terms of simplification for the purposes of pedagogy.

    Simon Blackburn on respecting religion

    Via Chris Hallquist, an interesting paper by the atheist philosopher Simon Blackburn, titled "Religion and Respect" (24pp. PDF).

    Worth noting as an abbreviated summary of the paper is the H.L. Mencken quote referenced by a commenter on Hallquist's post:

    "We must respect the other fellow's religion, but only in the sense and to the extent that we respect his theory that his wife is beautiful and his children smart."

    Interesting articles in The Economist

    A few articles of interest from the last couple of issues of The Economist:

    February 23, 2008: "Moral thinking," a summary of recent research that sheds light on human moral reasoning processes. Video here. (A related, more in-depth story is Steven Pinker's "The Moral Instinct" which appeared in The New York Times Magazine on January 13.)

    March 1, 2008: "Winds of change," a summary of research to use breathalyzer technology to diagnose medical conditions.

    "Telltale hairs," about new methods of forensics to use hair analysis to identify a person's location at a given time (based on water consumption--could drinking imported bottled water be used to thwart this?).

    Who's Who in Hell is now online

    Warren Allen Smith's massive Who's Who in Hell (2000, Barricade Books) is now online as a wiki, provided by the organization Philosopedia (not yet a 501(c)(3)), which manages a wiki of the same name.

    Unfortunately, they're not allowing the public to edit the content. I hope they will at least open it up to registered users in some way. It's also somewhat disappointing that the organization of Who's Who in Hell puts all the entries into 26 wiki pages, one per letter of the alphabet, rather than having a separate entry for each person. My entry on the L page is woefully out of date.

    UPDATE: But they're quite responsive... I have a new entry already.

    John Allen Paulos comes out with an atheism book

    John Allen Paulos, the mathematician and author of such excellent books as Innumeracy, A Mathematician Plays the Stock Market, and A Mathematician Reads the Newspaper (all three of which I recommend), has a new book coming out on January 3, 2008 titled Irreligion: A Mathematician Explains Why the Arguments for God Just Don't Add Up. Here's the review from Publishers Weekly:
    Few of the recent books on atheism have been worth reading just for wit and style, but this is one of them: Paulos is truly funny. Despite the title, the Temple University math professor doesn't actually discuss mathematics much, which will be a relief to any numerically challenged readers who felt intimidated by his previous book Innumeracy: Mathematical Illiteracy and Its Consequences. In this short primer ("just the gist with an occasional jest") Paulos tackles 12 of the most common arguments for God, including the argument from design, the idea that a "moral universality" points to a creator God, the notion of first causes and the argument from coincidence, among others. Along the way, he intersperses irreverent and entertaining little chapterlets that contain his musings on various subjects, including a hilarious imagined IM exchange with God that slyly parodies Neale Donald Walsch's Conversations with God. "Why does solemnity tend to infect almost all discussions of religion?" Paulos asks, clearly bemoaning the dearth of humor. This little book goes a long way toward correcting the problem, and provides both atheists and religious apologists some digestible food for thought along the way. (Jan. 3)
    I hope the IM exchange described is as witty and funny as Raymond Smullyan's dialogue with God, "Is God a Taoist?" (also found in his excellent book The Tao is Silent and in Daniel Dennett and Douglas Hofstadter's anthology, The Mind's I).

    UPDATE (January 14, 2008): Jim Holt reviews Paulos' book for the New York Times.

    Draper vs. Plantinga on Evil and Evolution

    Part two of the Internet Infidels' "Great Debate" project has been posted at the Secular Web, on "Evil and Evolution." Draper makes an argument for atheism on the basis of a version of the problem of evil informed by evolution, and Plantinga gives a version of his argument that evolution undermines naturalism. Each offers an objection to the other, followed by a reply.

    Reader questions are being solicited for the next couple of months, which the authors will respond to on the site.

    Radical Honesty

    There's an interesting and entertaining article at Esquire about Brad Blanton's Radical Honesty movement, which seems to me to take a good idea--being honest--too far into inappropriate sharing or "too much information." I think even little white lies (and especially "bullshit") can be extremely insidious, and should be avoided, but that doesn't mean removing all filters between thought and speech.

    James Morrow wrote a 1992 novel called City of Truth in which he described a world where everyone always speaks the truth in a way quite similar to the radical honesty movement, but the main character finds a need to lie in order to save his son's life.

    Plato and Machiavelli would agree with each other that no political leader could survive by adopting the radical honesty approach. I think that's disappointingly true.

    Why is there something rather than nothing?

    The latest issue of Skeptic magazine (vol. 13, no. 2, 2007, pp. 28-39) has an article by Robert Lawrence Kuhn which supplies a nice list of possible explanations for the answer to the question "Why is there something rather than nothing?" The article, titled "Why This Universe? Toward a Taxonomy of Possible Explanations" (PDF), briefly sets out descriptions of each explanation, but the meat of the article is found in the footnotes, which provide extensive references for each offered explanation.

    Here's the list, minus the footnotes and descriptions:

    1. One Universe Models
    1.1 Meaningless Question
    1.2 Brute Fact
    1.3 Necessary/Only Way
    1.4 Almost Necessary/Limited Ways
    1.5 Temporal Selection
    1.6 Self Explaining

    2. Multiple Universes
    2.1 Multiverse by Disconnected Regions (Spatial)
    2.2 Multiverse by Cycles (Temporal)
    2.3 Multiverse by Sequential Selection (Temporal)
    2.4 Multiverse by String Theory (with Minuscule Extra Dimensions)
    2.5 Multiverse by Large Extra Dimensions
    2.6 Multiverse by Quantum Branching or Selection
    2.7 Multiverse by Mathematics
    2.8 Multiverse by All Possibilities

    3. Nonphysical Causes
    3.1 Theistic Person
    3.2 Ultimate Mind
    3.3 Deistic First Cause
    3.4 Pantheistic Substance
    3.5 Spirit Realms
    3.6 Consciousness as Cause
    3.7 Being and Non-Being as Cause
    3.8 Abstract Objects / Platonic Forms as Cause
    3.9 Principle or Feature of Sufficient Power

    4. Illusions
    4.1 Idealism
    4.2 Simulation in Actual Reality
    4.3 Simulation in Virtual Reality
    4.4 Solipsism

    One of the most entertaining philosophical books I've ever read was David Lewis' On the plurality of worlds (pretty much everything Lewis wrote was entertaining as well as brilliant), which falls in category 2.8 (Multiverse by All Possibilities), cited by Kahn in note 43. The same category includes another very entertaining philosophy book, Robert Nozick's Philosophical Explanations, which is cited in note 44.

    This taxonomy shows that there are a lot more possibilities than "God did it."

    UPDATE: Thanks to John Lynch at stranger fruit, who pointed out that the article is available online.

    Scott Adams' lame arguments for copyright

    Scott Adams' lame arguments for copyright are taken apart by Kevin Carson at the Mutualist Blog. There are good arguments to be made for some form of copyright protection, but Adams doesn't make them.

    I guess it's not just the subject of evolution where Adams goes off the rails.
