Kevin Roberts' dog-killing story

 Kevin Roberts, the president of the Heritage Foundation and head of Trump's Project 2025, was previously a history professor at New Mexico State University. While at the university, he told colleagues and dinner guests that he was irritated by the barking of a neighbor's dog, so he killed it with a shovel. Kenneth Hammond, then chairman of the history department, told The Guardian:

My recollection of his account was that he was discussing in the hallway with various members of the faculty, including me, that a neighbor’s dog had been barking pretty relentlessly and was, you know, keeping the baby and probably the parents awake and that he kind of lost it and took a shovel and killed the dog. End of problem.

Two other former colleagues report hearing the same story directly from Roberts; three others report hearing the story repeated from people who heard it directly from Roberts.

Roberts denies the story, claiming instead:

In 2004, a neighbor’s chained pit bull attempted to jump a fence into my backyard as I was gardening with my young daughter. Thankfully, the owner arrived in time to restrain the animal before it could get loose and attack us.

Tips on using OpenBSD's pledge and unveil in perl scripts

 OpenBSD 5.9 (current as of this post is 7.5) introduced the "pledge" system call and 6.4 introduced the "unveil" system call, which together provide a means of more granular control of system access by processes running on the system to enforce least privilege.  When a program calls "pledge", it provides a list of categories of system calls (called "promises") that it is planning to make during the life of the running process (children have to make their own pledges and are not restricted), and attempts to make calls outside of those areas will cause the call to be blocked and the process to be killed. Additional calls to pledge cannot add new categories but it can remove them, so access can become more restrictive but not less restrictive.

  "Unveil," by contrast, selectively exposes parts of the file system, by file path, with specific access, and the rest of the file system is correspondingly "veiled" or blocked from access. Successive calls to unveil can expand or override previous ones, expanding access to the file system, adding write and create permissions where there was previously read only, but only until unveil is called with no arguments, which locks the current state in place. Further attempts to call unveil after that result in a violation.

Violations of pledges or attempts to access file paths that are not unveiled show up in process accounting logs for the process with the process flags "P" or "U", respectively.  (My "reportnew" log monitoring script knows how to monitor process accounting logs and can be easily set up to report on such violations.)

Perl scripts on OpenBSD can also use pledge and unveil, with two modules provided in the base operating system, "OpenBSD::Pledge" and "OpenBSD::Unveil".  I've been adding this functionality to several of my commonly used scripts and have learned a few tips that I'd like to share.

Pledge:

* Check your call to pledge for errors.  If you typo the name of a promise (category of system calls), or you provide pledge with a string of comma separated promises instead of an array or list, it will fail and nothing will be pledged.

* If you don't have any idea what promises are required, just use "error".  With the error promise, instead of blocking the system call and killing the process, the result is logged to /var/log/messages and you can see what promises are required.

* The "stdio" promise is always included with OpenBSD::Pledge, so you don't need to list it.

* The "unveil" promise is required if you intend to use OpenBSD::Unveil.

* Calls to exec or system require the "proc" and "exec" promises; the new processes created as a result are not restricted and need to make their own use of pledge and unveil.  (Note: this means that if you are calling a system command that writes to a file, but your script doesn't otherwise write to files, you do not need to pledge the "wpath" promise in your script.)

* If you otherwise fork a child process (e.g., explicitly using "fork" or Parallel::ForkManager or implicitly forking a child process using "open" to read from or write to a command), the promises pledged by the parent process are carried over to the child, which can then restrict them further. (Hat tip to Bryan Steele, who pointed this out on Bluesky without specifically referring to the Perl context.)

* If you use the DBI perl module with mariadb and are accessing a database through a named pipe on the same server, you'll need to pledge the "unix", "inet", and "prot_exec" promises. (This works even from a chroot jail if the named pipe or socket is a hard link from the jail.)

* This isn't a tip, but an observation: if you promise "proc" but not "exec," your system call will fail but your process will not be killed and the script will continue running.

Unveil:

* If you make use of other perl modules in your code with "use", they are loaded prior to your call to unveil and so you don't need to unveil directories like /usr/libdata/perl5 in order to use them. The exception is perl modules that include compiled shared objects (".so"), or which use "require" on other modules (loading them at runtime), in which case you do need unveil such directories, but only with "r" permission.

* If you use the DBI perl module with mariadb, you will need to unveil /var/run/mysql with "rw" and /usr/lib and /usr/local/lib with "rx".

* If you use calls to "system" or "open" which use pipes, globs, or file redirection, you need to unveil "/bin/sh" with "x" permission. You may be able to rewrite your code to avoid the requirement--can you call "system" with a command name and list of arguments rather than a string, and do any processing you need in your program instead of with the shell?

* If you use calls to "system" to execute system commands, you need to unveil them with "x" permission but in most cases you don't need to include "r".

* It is often much easier to unveil a directory rather than individual files; if you plan to check for the existence of a file and then create it if it doesn't exist, you need "rwc" on the containing directory.

* One of the biggest challenges sometimes is to find the source of an unveil violation; unveiling "/" with various permissions to see if it goes away, and then removing that and testing individual directories under the root directory in trial and error can help find things. That's how I first found the need to unveil "/bin/sh".

Finally, if you are writing perl modules it's helpful to document which promises need to be pledged and files and directories need to be unveiled in the calling scripts in order for them to function. It would be inappropriate to pledge or unveil within the module except in a context like a forked child process. I've done this with my Signify.pm wrapper for the OpenBSD "signify" command for signing and verifying files with detached signatures or gzip archives with embedded signatures in the gzip header comments.

If you've made use of pledge and unveil--in perl scripts or otherwise--what lessons have you learned?

Wikipedia, Skeptical Inquirer, and AI on Robert A. Baker plagiarism accusations

 The Wikipedia entry for University of Kentucky psychologist and skeptic Robert A. Baker recently (December 2023) restored a section on plagiarism accusations against him, which originated in a 1994 letter to the editor of Skeptical Inquirer from Jody Hey and were compounded by further accusations by Terence Hines and by me the same year. Unfortunately, the Wikipedia entry currently leaves the debate the same way the Skeptical Inquirer did in 1995, giving Baker the final word with a transparently false explanation.  Here's how the Wikipedia entry currently presents the issue:

Readers of Skeptical Inquirer, noticed in 1994 similarities between one of Baker's articles and William Grey's article Philosophy and the Paranormal, Part 2. After discovering this, Baker wrote to Grey apologizing for "forgetting both the direct quotation and the reference citation", he claims that it was an oversight. Grey publicly accepted Baker's apology in the Skeptical Inquirer.^[20] In the following year, author Terence Hines accused Baker of unattributed quotations from an article by Melvin Harris and from his own book Pseudoscience and the Paranormal.^[21] Baker responded in Skeptical Inquirer. stating that he used Melvin Harris' book Investigating the Unexplained as a source, rather than the article or Hines' book, and that he gave Harris credit but forgot the quotation marks.^[22]

This description is faulty in that it omits most of the evidence and is inconsistent with it. The most detailed account can be found in my 1994 report given to leaders at the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP, now the Committee for Skeptical Inquiry or CSI) and subsequently published in 1995 to Usenet and its update. I've also assembled a chronology of events that led to my involvement and included legal threats from Baker, which I've now updated to include a letter from Paul Kurtz in his role as head of Prometheus Books noting that Baker's book Hidden Memories had been withdrawn from publication. While I've not exhaustively searched Baker's work, I found fairly consistent plagiarism in his books for Prometheus and his book reviews for Skeptical Inquirer throughout his career as a skeptic.

The rest of this post will first show that Baker's claim to have used Harris as a source, but not Hines, is false--there is clear evidence that Baker plagiarized Hines, whose book he did not cite (and his text matches Harris's article rather than the book where they differ). Second, it will show the heaviest section of plagiarism I identified in another Baker book, They Call It Hypnosis (1990, Prometheus Books). Finally, it will show that Baker's institution defined research misconduct in a way that includes what he did, and that Baker's own writing shows that he understood this to be misconduct.

The exchange between Hines and Baker in the pages of the July/August 1995 Skeptical Inquirer (pp. 44-46) focuses on a passage on p. 157 in chapter 4 of Baker's book, Hidden Memories: Voices and Visions from Within (1992, Prometheus Books) and its resemblance to a passage on p. 74 in Hines' book, Pseudoscience and the Paranormal (1988, Prometheus Books) where he quotes from p. 23 of an article by Melvin Harris, "Are 'Past-Life' Regressions Evidence of Reincarnation?", Free Inquiry, Fall 1986, vol. 6, no. 4, pp. 18-23 (quotation marks as given in Hines):

"...every single piece of information given by Jane Evans can be traced to de Wohl's fictional account. She uses his fictional sequences in exactly the same order and even speaks of his fictional characters, such as Curio and Valerius, as if they had been real."

Hines notes that Baker uses nearly the same words in the same sequence, without quotation marks or references, on p. 157 of Hidden Memories:

Every single piece of information given by Mrs. Evans could be traced to De Wohl's book, and Mrs. Evans used his fictional sequences in exactly the same order as he had, and even spoke of De Wohl's fictional characters, Curio and Valerius, as if they had been real.

Here is how Harris makes the same statement on p. 162 of his book, Investigating the Unexplained (1986, Prometheus Books), which Baker claims is his source (italics in original):

In the same way every single piece of information given out by Jane Evans can be traced to De Wohl's fictional account. She uses his fictional sequences in exactly the same order and even speaks of his fictional characters--such as Curio and Valerius--as if they were real people.

Harris's article (p. 23):

In the same way, every single piece of information given by Jane Evans can be traced to De Wohl's fictional account. She uses his fictional sequences in exactly the same order and even speaks of his fictional characters, such as Curio and Valerius, as if they were real people. 

Baker's wording omits the "out" in the first sentence, uses commas instead of hyphens, and doesn't use the italicization, all matching the article rather than the book.

Baker cites neither Harris nor Hines in the notes for chapter 4 of his book. He does mention Melvin Harris twice on the page with no citation and no attributed quotations, including once in the same paragraph as the above quotations. Baker's discussion of other cases earlier in the chapter differs from Hines and Harris--all three discuss Bridey Murphy, but Baker's case is more extensive than Harris or Hines. I suspect his sources may be identifiable from the other references he gives at the end of the book for the chapter.

But when it comes to Baker's discussion of Jane Evans, he engaged in more plagiarism of Hines, as can be seen by comparing his text to Hines and to Harris's article and book. Harris discusses the case extensively on pp. 155-163 of his book, while Hines' and Baker's discussions are each less than two pages long.

Here is what Baker writes (pp. 156-157), with exact word matches with Hines highlighted in yellow, and with Harris' article in orange (and I found no matches to Harris's book which did not also match the article):

The second, and by far the most [Harris: much more] impressive, was the case of a Welsh housewife named Jane Evans, who described six past lives that were remarkable for the tremendous amount of accurate historical detail [Harris: amount of detail] they contained. In one of the lives she was a maid in the house of a wealthy [Baker, p. 157:] and powerful merchant in fifteenth-century France. Mrs. Evans described accurately the house and all of its furnishings in great detail, as well as the members of the merchant's family. She made one very significant error in her account, however. She said the merchant was unmarried [Hines: not married] and had no children. In truth he was married and had five children, circumstances no maid would be unaware of. The same failure to mention wife and children turned up in a novel that had been written about the merchant, titled The Moneyman by Thomas B. Costain (1948). According to Melvin Harris, who investigated the case, the evidence is overwhelming that this book was the source of all of Mrs. Evan's [sic; Hines: basis for Evans's] "memories" of her life in fifteenth-century France.

   In another life that she reported, Mrs. Evans was a woman named Livonia, who lived during the Roman occupation of Britain. Her account [Hines: knowledge] of the historical facts of this [Hines: that] period was so accurate that authorities [Harris: authority] on Roman Britain were astounded. Again, however, there were a few factual errors. Her knowledge [Hines: information] of the period was traced to the 1947 best-selling novel The Living Wood by Louis De Wohl. Every single piece of information given by Mrs. Evans could be traced to De Wohl's book, and Mrs. Evans used [Hines, Harris: she uses] his fictional sequences in exactly the same order as he had, and even spoke [Hines, Harris: speaks] of De Wohl's [Hines, Harris: his] fictional characters, Curio and Valerius, as if they had been [Hines, Harris: were] real. The historical errors in Mrs. Evan's [sic] account were also found in the book. As Harris clearly demonstrated, Mrs. Evans had [Harris: had] the ability to store vivid stories in her subconscious and then creatively combine and edit them to the point that [Harris: where] she herself became [Harris: becomes] a [Harris: one of the] character in the story [Harris: involved].

This last sentence is another in which Baker follows Harris's article more closely than his book, which suggests Baker used the article in addition to Hines (who doesn't quote this sentence).  Harris's book (p. 161) says "... Jane Evans has the ability to subconsciously store vivid accounts and combine and edit these creatively--to the point where she becomes one of the characters involved." The article (p. 22) says "...Jane Evans has the ability to store vivid tories in her subconscious and creatively combine and edit them to the point where she becomes one of the characters involved."

Overall, Baker follows Hines more closely than Harris, and when there are discrepancies between Harris's article and book, Baker follows the article.  While Harris names the maid (Alison), neither Hines nor Baker do. In structure, after introducing the maid, Hines and Baker mention Evans' description of the house and furnishings, but Harris only mentions that after describing Evans' "inside-knowledge of the intrigues surrounding the King's mistress, Agnes Sorel," which Hines and Baker omit. The sentences from Hines and Baker that immediately follow the house and furnishings differ slightly in wording but are strikingly similar:

Hines (p. 73): "Evans' account of her life in Coeur's house contains one most puzzling, and significant error. She says he was not married and had no children. But he was married and had five children--not the sort of thing the maid would be likely to overlook."

Baker (p. 157): "She made one very significant error in her acccount, however. She said the merchant was unmarried and had no children. In truth he was married and had five children, circumstances no maid would be unaware of."

Harris, by contrast, is quite different (p. 22): "In particular, the novel very neatly answers an important question raised by Iverson and other commentators: Why doesn't Alison know that her master is married? As Iverson puts it: 'How is it that this girl can know Coeur had an Egyption bodyslave and not be aware that he was married with five children?--a published fact in every historical account of Coeur's life?...If the explanation for the entire regression is a reading of history books in the twentieth century, then I cannot explain how Bloxham's subject would not know of the marriage.'"

For completeness, here's Harris's book, which differs very slightly (p. 158): "In particular, the novel very neatly answers an important question raised by Iverson and other commentators--a question prompted by the curious fact that Alison does not know that her master is married! As Iverson puts it: 'How is it that this girl can know Coeur had an Egyptian bodyslave and not be aware that he was married with five children?--a fact published in every historical account of Coeur's life? ... If the explanation for the entire regression is a reading of history books in the twentieth century, then I cannot explain how Bloxham's subject would not know of the marriage.'"

In short, Baker plagiarized Hines and Harris, and his explanation is not consistent with the facts, with the truth revealed in much the same way as the truth was revealed about Evans' stories being sourced from fiction.

Next, we turn to Baker's They Call It Hypnosis, where Baker repeatedly plagiarized sources word-for-word without quotation marks, sometimes referencing them in the chapters where used, sometimes not referencing them in the chapter, and sometimes not referencing them at all (see my full report for more examples of each). In these examples, Baker lifts from work by Nicholas P. Spanos, by Spanos and co-author John F. Chaves, and by Irving Kirsch and James R. Council, with his only original contributions being some introductory or connecting phrases and substitution of synonyms. Here is what appears on pp. 129-131 of They Call It Hypnosis, part of chapter three titled "Hypnosis: Recent and Contemporary Views," with highlights indicating word-for-word plagiarism from the sources used:

     [Baker, p. 129] Overall, Spanos's position on hypnosis is very clear. He argues that, despite widespread belief to the contrary, hypnotic procedures do not greatly augment responsiveness to suggestions. Nonhypnotic control subjects who have been encouraged to do their best respond just as well as hypnotic subjects to suggestions for pain reduction, amnesia, age regression, hallucination, limb rigidity, etc. Hypnotic procedures, he says, are no more effective than nonhypnotic relaxation procedures at reducing [Spanos: lowering] blood pressure and muscle tension or affecting [Spanos: effecting] other behavioral, physiological, or verbal report indicators of relaxation. Hypnotic procedures are no more effective than various nonhypnotic procedures at enhancing imagery vividness or at facilitating therapeutic change for such problems as chronic pain, phobic response, cigarette smoking, etc. The available scientific evidence that Spanos and his collaborators have compiled fails to support the notion that hypnotic procedures bring about unique or highly unusual states of consciousness or that these procedures facilitate responsiveness to suggestion to any greater extent than nonhypnotic procedures that enhance positive motivation and expectation. [Spanos, p. 175]

     Spanos also notes that hypnotic suggestions do not directly instruct the subject to do anything. Instead, they [Spanos: suggestions] are usually phrased in the passive voice and imply that something is happening; for example [Spanos: e.g.], "Your arm is rising," instead of "Raise your arm." The [Spanos: This] passive phrasing communicates the idea that the suggested effects are occurring [Spanos: happening] automatically. In other words, the hypnotic suggestions are really tacit requests to the subject to become [Baker, p. 130 begins:] involved in a make-believe activity. Good hypnotic subjects understand this [Spanos: the implications of these tacit requests] and use their imaginative abilities and acting skills to become absorbed in the make-believe activities [Spanos: scenarios]. Spanos notes that the method actor who throws himself into the role is the analogue of the good hypnotic subject who throws himself [Spanos: themselves] into generating the experiences relevant to his [Spanos: their] role as someone who is hypnotized and responsive to suggestions. [Spanos, pp. 175-176]

     Spanos and his collaborators have looked closely at hypnotic age regression and have demonstrated that regressed subjects do not, in any real sense, take on the cognitive, perceptual, or emotional characteristics of actual children. Instead of behaving like real children, age regressed subjects behave the way they believe children behave. To the extent that their expectations about how children behave are inaccurate, their age regression performances also are off the mark. Simply put, age regression suggestions are invitations to become involved in the [Spanos: this] make-believe game of being a child again. People who accept the invitation do not, in any literal sense, revert psychologically to childhood. Instead, they use whatever they know about real children, whatever they remember from their own childhood, to temporarily become absorbed in the fantasy of being a child again. [Spanos, p. 176]

     Just as subjects can be given suggestions for age regression, amnesia, or pain reduction, Spanos says they can also be led to believe that they possess "hidden selves." When Hilgard's good hypnotic subjects were told [Spanos: informed] that they possessed hidden selves they normally were unaware of--but to which the experimenter could talk when he gave [Spanos: by giving] the proper [Spanos: appropriate] signals--many of them [Spanos: these subjects], when the signals were given [Spanos: they received], acted [Spanos: behaved] as if they did have alternate egos [Spanos: possessed secondary selves]. Hilgard interpreted this as indicating [Spanos: interpret such findings to mean] that good hypnotic subjects carry around unconscious hidden selves with certain intrinsic, unsuggested characteristics. Spanos counters this by pointing out that the evidence shows these [Spanos: indicates instead that] so-called hidden selves are neither intrinsic to hypnotic procedures nor unsuggested. On the contrary, hidden self-performances--like other suggested responses--appear to reflect attempts by motivated and imaginative subjects to create the experiences and role-play the behaviors [Spanos: role behaviors] called for by the instructions they are given. By the experimenter varying these [Spanos: such] instructions, the subjects can be easily led to develop hidden selves with whatever characteristics the experimenters desire [Spanos: wish]. Depending upon the instructions given, good hypnotic subjects will act out [Spanos: enact] hidden selves reporting [Spanos: that report] very high levels of pain, very low levels of pain, or both high and low levels of pain in succession. Subjects can also be led to act as if they possess hidden selves that can remember concrete but not abstract words, or the opposite; or they can report seeing [Spanos: that see] stimuli accurately, seeing them [Spanos: see stimuli] in reverse, or not seeing them [Spanos: don't see stimuli] at all; as the experimenter wishes. In short, the subjects are [Spanos: subject is] acting out a fantasy which is initiated by the suggestions of the hypnotist. Then the fantasy is imaginatively elaborated upon and sustained by the subject and his interactions with the hypnotist. [Spanos, pp. 176-177]

     [Baker, p. 131 begins:] Spanos has also carried out studies of past-life regression, and in agreement with the findings of other researchers, his work indicates that past-life reports from hypnotically regressed subjects are fantasy constructions of imaginative subjects who are willing to become absorbed in the make-believe situation implied by the regression suggestions. As expected, subjects who responded well to other hypnotic suggestions were the most likely to respond well to regression suggestions. Those with the most practice at vivid daydreaming and everyday fantasizing, i.e., the fantasy-prone, created the most vivid past-life fantasies. In the same manner as childhood regressees, past-life reporters incorporate historical misinformation into their past lives [Spanos: -life enactments]. Those who from the outset believed in reincarnation thought their past lives were true [Spanos: -life experiences were veridical] rather than imaginary. A lengthier discussion of this topic and other paranormal hypnotic beliefs will be found in a later chapter. [Spanos, p. 179]

     By no means, however, does Spanos see the problem of hypnosis as solved. New knowledge leads us to new unknowns and in the well-known and pronounced effects of suggestion on the human body there are many unsolved problems. The suggestion-induced disappearance of warts, for example, is just such a dilemma. Spanos's own work has shown that neither a hypnotic induction nor preliminary instructions for relaxation add to the effectiveness of imagery-based suggestions in producing wart regression. Nor can the effects of suggestion be accounted for simply in terms of enhanced expectancies. Subjects given placebos and those given suggestions reported equivalent expectations of treatment success, but the suggestions were much more effective than the placebos in [Spanos & Chaves: at] producing wart regression. The suggestions, however, were not effective with all the subjects. They were most effective, Spanos reports, with subjects who had [Spanos & Chaves: possessed] multiple warts rather than [Spanos & Chaves: as opposed to] single warts. Those who rated their suggested imagery as especially [Spanos & Chaves: relatively] vivid also had better results. [Spanos & Chaves, pp. 445-446]

At this point, Baker says "Spanos concludes that" followed by a large block of correctly cited and quoted text from Spanos & Chaves p. 446 that fills the rest of p. 131, with a concluding sentence on p. 132 that appears to be original. Baker goes on in pp. 132-134 to describes the views of Irving Kirsch under the heading "Irving Kirsch and Response Expectancy in Hypnotic Behavior," with an original opening paragraph that cites Irving Kirsch, "Response expectancy as a determinant of experience and behavior," American Psychologist 1985, vol. 40, pp. 1189-1202, a source he does not plagiarize. But he goes on to plagiarize a source that he cites nowhere in his book, Kirsch & Council's chapter from Spanos & Chaves' book (which book he does list as a reference at the end of the chapter, but doesn't cite in the section). There is more original content in this section, and more extensive rewriting, but the level of plagiarism increases as it goes on:

[Baker, p. 132:] In the latter part of the nineteenth century, Albert Moll argued [Kirsch & Council, p. 360: maintained] that hypnotic behavior was determined by two basic principles: 1) people [Kirsch & Council, quoting Moss, 1897, p. 241: men] have a certain proneness to allow themselves to be influenced by others through their ideas, and in particular, to believe much without making conscious logical deductions; 2) a psychological effect tends to appear in a person [Kirsch & Council, quoting Moss, 1897: man] if he is expecting it. Moll also was able to cause his [Kirsch & Council: elicit hallucinations by leading] blindfolded subjects to hallucinate when he told them [Kirsch & Council: to believe] they were being mesmerized.

   Moll's giving expectancy a role in the production of hypnotic phenomena anticipated Kirsch's thinking that response expectancies cause [Kirsch & Council, p. 361: generate corresponding] the individual to have internal subjective experiences which then cause [Kirsch & Council: and their] behavior [Kirsch & Council: behavioral and physiological correlates]. A very clear [Kirsch & Council: particularly apparent] example of this is the placebo effect. When the patient is given a sugar pill but is told or believes it is a powerful pain killer, miraculously, because of his expectancies, the pain goes away! As for hypnosis, according to Kirsch, the occurrence of a hypnotic response is a function of the subject's expectancy that it will occur. Once the subject has learned how a hypnotized subject is supposed to react and what he can expect to happen when he is hypnotized, then the hypnotic responses occur automatically, i.e., without conscious effort on the subject's part. Emotional reactions--fear, sadness, sexual arousal, pain--are good examples of automatic responses. Acrophobics, for example, will avoid tall buildings, cliffs, ferris wheels, etc., because of their expectancy that not doing so would result in a panic attack. 

   Various other evidence [Kirsch & Council, p. 362: A considerable body of data] is available to demonstrate that automatic [Kirsch & Council: nonvolitional] responses can be brought about [Kirsch & Council: elicited] by the mere expectancy of their occurrence. Both hypnosis and placebos are effective in treating pain, skin conditions, and asthma, and it seems reasonable to assume that the same mechanism, namely, response expectancy, produces these responses in both hypnosis [Baker, p. 133:] and the nonhypnosis situations. Telling subjects [Kirsch & Council, p. 364: informing them] they have received [Kirsch & Council: were ingesting] a psychedelic drug that will produce hallucinations causes about half [Kirsch & Council: 50 percent] to report visions, even though no drug was given. Subjects [Kirsch & Council: people] who are told that hypnotized subjects can't move their [Kirsch & Council: display catalepsy of the] dominant arm are likely to experience this effect when hypnotized, and being told [Kirsch & Council: informed] that inability to remember, i.e., spontaneous amnesia, is characteristic of hypnosis significantly increases the likelihood of its occurrence. When subjects were told that either the ability or the inability to resist responding to suggestions was characteristic of deep hypnosis, they responded accordingly.

   Besides affecting overt responses, role perceptions are an important determinant of self-reported experiences of altered states of consciousness. In a number [Kirsch & Council, p. 365: series] of studies it was shown [Kirsch & Council: this has been convincingly demonstrated] that the degree of change in state of consciousness subjects expected to experience significantly predicted the number of unsuggested alterations in experience they subsequently reported. Moreover, the data from these studies indicate [Kirsch & Council, p. 366: suggest] that no particular state of consciousness can be labeled a "hypnotic trance." Rather, a variety of changes in experience are interpreted by the subject as evidence of trance when experienced in a hypnotic context. Some of these are directly suggested in typical hypnotic induction--relaxation, for example [Kirsch & Council, p. 367: e.g.]--whereas others occur as a function of the subject's preconceptions. How the subject perceives the situation pretty much determines how effective the situation will be in producing hypnosis. Just hearing the words, "You are becoming very, very relaxed," is enough in our culture to make most people think [Kirsch & Council, p. 368: evokes the idea] of hypnosis. Glass and Barber (1961) a few years ago set up [Kirsch & Council: devised] a highly credible clinical environment and told subjects an inert pill was a powerful hypnotic drug which would produce a state of hypnosis. In this setting the pill was as effective as a standard hypnotic induction procedure in effecting [Kirsch & Council: raising levels of] the subject's responses to suggestion.

The rest of p. 133 of Baker is two original sentences that introduce a large block of text (five full sentences) properly identified as quotation and attributed to the Spanos & Chaves book without a page reference; it is from p. 371 in the Kirsch & Council chapter. Baker p. 134 completes the Kirsch section:

According to Kirsch's [Kirsch & Council, p. 371: expectancy] theory, the probability of occurrence of a nonvolitional response varies directly with the strength of the expectancy of the occurrence and inversely with the magnitude or difficulty of the expected response. [Baker has removed Kirsch & Council's quotation marks before "the probability"; the rest of the sentence is a direct quote from Kirsch's 1985 paper.]

   Trance induction procedures are, of course, typically designed to increase the subject's expectancies for responding to suggestions, and in the Ericksonian approach [Kirsch & Council: clinical practice] the hypnotist tailors his induction to the characteristics and ongoing behavior of the client [Kirsch & Council: individual subjects]. Kirsch sees most hypnotic induction procedures as merely expectancy modification procedures.

   Kirsch's response expectancy theory [Kirsch & Council, p. 374: hypothesis] is generally consistent with the nonstate theories of Sarbin, Barber, Wagstaff, and Spanos. All agree that hypnotic responses are best seen [Kirsch & Council: can be conceptualized] as compliance, belief, and imagination [Kirsch & Council: believed-in imaginings], and that the hypnosis experience occurs when people voluntarily play [Kirsch & Council: take on] the role of hypnotic subject. One key difference between Kirsch's theory and others is that his response expectancies are the immediate causes of the hypnotic response. Rather than having goal-directed images enhancing hypnosis, as Barber suggests, Kirsch has shown that the imagery enhances responsiveness by virtue of its effects on expectancy. Kirsch has also shown that not all so-called hypnotic phenomena are under a subject's will power or self-control [Kirsch & Council, p. 378: cannot be fully accounted for as volitional behavior]. Warts, for example, can be affected both by placebos and by hypnosis, and such changes in skin conditions are not under one's voluntary control. Kirsch notes that one could offer subjects a substantial sum of money to make their warts disappear, but it is highly unlikely that many subjects would be able to do so.

This phenomenon also clearly shows [Kirsch & Council, p. 378: demonstrates] the commonality between hypnosis [Kirsch & Council: hypnotic phenomena] and placebo effects. Both are examples of the nonvolitional nature of response expectancy effects. Kirsch's observation raises another point of significance--the fact that we must realize that not everything that happens to the human being as a result of external stimulation is or should be considered hypnosis! Suggestion is a very powerful influence on human behavior and it can influence human behavior in many different ways, only a very few of which we would or should designate as "hypnotic."

I reviewed Baker's They Call It Hypnosis for Amazon.com on November 18, 1996, and gave it four stars; I might subtract another star today and say more about its giving state theories short shrift, but otherwise I still agree with this:

This book is an excellent summary of theories of hypnosis
with an emphasis on criticisms of state theories. The
author argues for social/cognitive non-state theories.
The book is marred only by the fact that many passages
are lifted directly from the authors being summarized,
without being noted as such.

Finally, here is the definition of research misconduct from the University of Kentucky's "Policy on Ethical Standards and Misconduct in Research" (64.0 AR II-4.0-2) from 1992:

Research "misconduct", as used herein, is defined as plagiarism; 
fabrication or intentional falsification of data, research procedures or 
data analysis; or other deliberate misrepresentation in proposing, 
conducting, reporting, or reviewing research.  It does not include 
honest error or honest differences in interpretations or judgments of 
data.  In cases of allegations involving activities submitted to or 
supported by a federal agency, the definition for misconduct specified 
in the agency's regulations will apply.

This policy was referenced in the faculty handbook section on "The Conduct of Research" in the paragraph on "Ethical Standards"; these are quoted more extensively in my full report. Baker was certainly aware of these in substance, as the following appears on p. 297 of Robert A. Baker and Joe Nickell's book, Missing Pieces: How to Investigate Ghosts, UFOs, Psychics, and Other Mysteries (1992, Prometheus Books):

Another question that is bound to arise has to do with rewriting and 
paraphrasing.  The courts once again have uniformly decided that it 
makes no difference whether the plagiarizer changes the arrangement of 
the original words or not--rewriting the material is not sufficient to 
aid the charge of infringement. ... More importantly, even if the use of 
the words and statements of another is totally honest, unintentional, or 
subconscious, it is still prohibited.  Neither forgetfulness nor 
ignorance is regarded as a legitimate excuse.  If, however, it was an 
honest and unintentional mistake, and no intent to plagiarize was in 
mind, the infringer usually gets off with a lesser punishment.

Baker's response to these allegations was at first to attack and concede nothing. He suggested that he was going to sue me for defamation, and enlisted the help of others who attempted to discredit me (see my letter to Tucson skeptic James McGaha). Ultimately, after psychologist Terence Hines, another prominent skeptic, was prepared to submit his book review of Baker's Hidden Memories, rejected by Skeptical Inquirer, to competing publication Skeptic magazine,  SI editor Kendrick Frazier relented and published the review along with Baker's reply. Baker fell back to the claim that his plagiarism was minor and unintentional, while resorting to falsehoods to attempt to prop up that explanation, as explained above. At this point, CSICOP founder and Prometheus Books head Paul Kurtz sent me a letter stating that Hidden Memories had been pulled from distribution and would not be reissued until corrections had been made; I replied noting that there were bigger problems in They Call It Hypnosis, but received no response.

Robert Baker was added to the Committee for Skeptical Inquiry's Pantheon of Skeptics honoring distinguished Fellows of the organization on its creation in 2011.

Skeptical Inquirer and Wikipedia, at least to date, both gave Baker's falsehoods the final word. And perhaps the more interesting back story here is that Wikipedia is wrong because Skeptical Inquirer is wrong, but the reason Wikipedia only even mentioned Baker's plagiarism at all in December 2023 is because a Wikipedia editor with no dog in the fight, "Psychologist Guy," intervened and restored an old edit of the article to include the mention, which had been removed in 2018 by another Wikipedia editor, "Niomart," with the false justification that "No valid source substantiating plagiarism claims".

As the Internet becomes more and more filled with AI-generated content, there will be sources with superficial plausibility generated by large language models, there will be sources that are human-curated and based on genuine research and fact-checking, and there will be sources that are human-curated and ideologically driven that settle on acceptable half-truths concealing messy details. OpenAI's ChatGPT 3.5 says it knows nothing of plagiarism by Robert A. Baker:

Did Robert A. Baker's 1992 book, Hidden Memories (pp. 156-157), plagiarize from Terence Hines' 1988 book Investigating the Unexplained (pp. 73-75)?

As of my last knowledge update in January 2022, I do not have specific information regarding an allegation of plagiarism between Robert A. Baker's book "Hidden Memories" and Terence Hines' book "Investigating the Unexplained" related to the pages specified. Therefore, I cannot definitively answer whether Baker's book plagiarized from Hines' book.

To investigate this further and obtain accurate information, I would recommend checking scholarly resources, academic databases, or reputable sources that discuss these books and any related allegations of plagiarism. You might also look into academic discussions or reviews of both books to see if there are any mentions of such accusations and their resolution.

Google Gemini quotes from and cites Wikipedia as the final word:

Was Robert A. Baker ever accused of plagiarism, or of failure to properly cite quotations and sources?

Yes, Robert A. Baker did face accusations of plagiarism in the past according to his Wikipedia page [Robert A. Baker Wikipedia].

Here's a summary of the incidents:

• In 1994, readers of Skeptical Inquirer identified similarities between Baker's article and another author's work. Baker apologized, claiming it was an oversight.
• The following year, another author pointed out unattributed quotes in Baker's writing. Baker defended himself by saying he used the original source but forgot quotation marks.

Bill Frist's cat-killing story

 After adding a post about Kristi Noem's dog-killing story, I realized I hadn't mentioned former House Majority Leader Bill Frist's (R-TN) cat-killing story. Jeff Woods gave a quick overview of the story, which appeared in Frist's 1989 autobiography, Transplant, in his review of Frist's later book in The Nashville Scene in 2009:

Never say Frist doesn't learn from his mistakes. In his 1989 autobiography Transplant, he admitted that as a medical student he adopted cats from animal shelters, "treat[ed] them like pets for a few days," then took them to a lab to die in research experiments. He blamed this conduct on the pressures of med school.

"And I was totally schizoid about the entire matter," Frist wrote. "By day, I was little Billy Frist, the boy who lived on Bowling Avenue in Nashville and had decided to become a doctor because of his gentle father and a dog named Scratchy. By night, I was Dr. William Harrison Frist, future cardiothoracic surgeon, who was not going to let a few sentiments about cute, furry little creatures stand in the way of his career. In short, I was going a little crazy."

That bit of honesty cost Frist no little embarrassment in his 1994 Senate campaign, when he was mocked as a cat killer.

Kristi Noem's dog-killing story

 Before the release of South Dakota Governor (and prospective Trump VP running mate) Kristi Noem's book, No Going Back: The Truth on What's Wrong With Politics and How We Move America Forward, the Guardian published an account of her story in the book of becoming angered with her 14-month-old family dog Cricket when it (running loose off-leash) killed a farmer's chickens. She took the dog to a gravel pit and shot and killed it, and then, for good measure, decided to kill a goat as well. She wrote that the dog was "untrainable" and that she "hated that dog." She proudly described this impulsive act of killing a family pet without consulting with her family and in an inhumane manner as an illustration of her willingness to deal with things that are "difficult, messy, and ugly." But her first response to the Guardian story was to call it "fake news," then to defend herself by claiming that the dog was "a working dog and not a puppy. It was a dog that was extremely dangerous."

Subsequently, she did the opposite of her book title by retracting a story from the book that she had "stared down" Kim Jong Un when she met him, after a Noem spokesperson said she never met Kim Jong Un. Her book also claimed that she had cancelled a meeting with France's President Emmanuel Macron, whose staff said she never had a meeting scheduled with him.

As a result of this story, I've created a tag on this blog for "conservative animal abuse" since several previous examples were covered here going back to 2007.

If embryos are babies, then in-vitro fertilization is immoral

Alabama and the GOP are discovering what this blog pointed out 15 years ago--if you're going to adopt a policy that embryos are full bearers of moral personhood, then you can't allow in-vitro fertilization (IVF). From my five-part debate with Vocab Malone about abortion in 2009:

Once the zygote becomes a blastocyst, it forms into an outer layer of cells, which later becomes the placenta, and an inner cell mass of pluripotent embryonic stem cells, each of which is capable of differentiating into any kind of human cell. Only after this stage does the blastocyst implant in the wall of the uterus, about a week after fertilization, and begin taking nutrients directly from the blood of the mother--a dependency that can itself be of moral significance, as Judith Jarvis Thomson's violinist argument shows. As already mentioned above, a great many fertilized ova do not reach this stage. Further, the percentages of implant failure are higher for in vitro fertilization (IVF), a procedure which Vocab's criteria would have to declare unethical, even though it is the only way that many couples can have their own biological offspring.

I made the same point earlier in a comment on a podcast interview with atheist anti-abortion advocate Jen Roth (comments are no longer present but I reiterated it in response to Malone):

Was Jen Roth ultimately arguing that personhood is something that a human organism has for its entire lifecycle? At what starting point? Conception, implantation, or something else?

I find it completely implausible that an organism at a life stage with no capacity for perception, let alone reason, counts as a person. Nor that a particular genetic code is either necessary or sufficient for personhood.

I think every point that she made was brought up in a debate I had with a Christian blogger on the topic of abortion, who similarly argued for an equation between personhood and human organism. I wonder if she has any better rejoinders. Does she think that IVF and therapeutic cloning are immoral? IUDs?

The naive anti-abortion position is philosophically and scientifically unsupportable and leads to bad public policy, and today's GOP consists of a majority struggling to avoid it and a minority that is full-steam ahead and prepared to ban IVF and contraception.

The full debate between Vocab Malone and myself was spread across our respective blogs.  My contributions were:

Vocab Malone on abortion and personhood, part 1 (December 11, 2009)

Vocab Malone on abortion and personhood, part 2 (December 13, 2009)

Vocab Malone on abortion and personhood, part 3 (December 16, 2009)

Vocab Malone on abortion and personhood, part 4 (December 18, 2009)

Vocab Malone on abortion and personhood, part 5 (December 19, 2009)

And, finally, perhaps most apt to the current situation, was this exchange from the following year:

Does Vocab Malone understand the implications of his own position? (November 15, 2010)

Vocab's response is that he does think IVF is immoral, except perhaps for some hypothetical version he doesn't describe, that perhaps involves adopting all the "snowflake babies" and removing and reimplanting excessive multiple births into surrogates. (But that still doesn't address the implantation failure rate!)

A short conversation with ChatGPT about the Grand Canyon

  ChatGPT does fairly well with this, though its selected points don't include any of the more obscure points of interest, it's skewed to the popular highlights. Its claim that there weren't any historic crossings is pretty odd.

What are some of the most beautiful and interesting locations in the Grand Canyon along the Colorado River?

The Grand Canyon offers numerous beautiful and interesting locations along the Colorado River. Here are some notable ones:

1. Havasu Creek: Located on the western side of the Grand Canyon, Havasu Creek is famous for its turquoise-blue waterfalls and pools. The stunning Havasu Falls, Mooney Falls, and Beaver Falls are among the main attractions.

2. Phantom Ranch: Situated at the bottom of the Grand Canyon, Phantom Ranch is a historic oasis accessible only by hiking or rafting. It provides a unique lodging option and serves as a hub for various hiking trails and activities.

3. Bright Angel Trail: This popular hiking trail descends from the South Rim down to the Colorado River. It offers breathtaking views of the canyon's layers, geological formations, and the river itself.

4. Hermit Rapids: Known for their tumultuous whitewater, the Hermit Rapids offer a thrilling experience for river rafting enthusiasts. These rapids are located in a remote and scenic section of the canyon.

5. Deer Creek Falls: Nestled in a picturesque alcove, Deer Creek Falls is a stunning waterfall that drops into a deep pool. The location also features the Deer Creek Narrows, a beautiful slot canyon to explore.

6. Lava Falls: Considered one of the most challenging and exciting rapids in the entire Grand Canyon, Lava Falls is a thrilling spot for experienced river runners. It provides an adrenaline-pumping adventure as you navigate through the turbulent waters.

7. Nankoweap Rapids: Located in a less visited area of the Grand Canyon, Nankoweap Rapids offer a mix of exciting rapids and serene camping spots. The views from Nankoweap Trail, which descends to the river, are awe-inspiring.

8. Redwall Cavern: This enormous natural amphitheater-like feature is carved into the Redwall Limestone cliffs. It offers a unique camping and picnic spot along the river, where groups can gather and enjoy the stunning surroundings.

Remember that exploring the Grand Canyon and its Colorado River region requires careful planning, permits, and appropriate equipment. Whether you choose to hike, raft, or simply admire the beauty from the rim, always prioritize safety and follow any guidelines or regulations set by the National Park Service.

What are some interesting human artifacts that are left behind within the Grand Canyon, either by native Americans from hundreds of years ago, from the late 19th century, or even from the 20th or 21st century?

The Grand Canyon has a rich cultural history, and various human artifacts have been left behind by different groups over the centuries. Here are some interesting examples:

1. Native American Petroglyphs and Pictographs: The canyon is home to numerous petroglyphs and pictographs created by Native American tribes who inhabited the area for thousands of years. These rock art sites provide glimpses into their cultural and spiritual practices. Key locations include the Bright Angel and Hermit Trails, Palatki Heritage Site, and Nankoweap Canyon.

2. Tusayan Ruins: Located on the South Rim, the Tusayan Ruins are the remnants of a Puebloan village that was inhabited around 800 years ago. The site includes a partially reconstructed dwelling and offers insights into the lives of the ancient inhabitants.

3. Historic Mining Sites: In the late 19th century, prospectors and miners ventured into the Grand Canyon in search of minerals and ores. Remnants of their activities, such as old mine shafts, rusted equipment, and structures, can still be found in certain areas, like the Bright Angel and South Kaibab Trails.

4. Grand Canyon Village: Established in the early 20th century, Grand Canyon Village is a historic district that features buildings constructed by the National Park Service and the Santa Fe Railroad. Many of these structures, including the El Tovar Hotel, Hopi House, and Bright Angel Lodge, reflect early 20th-century architecture and offer a glimpse into the region's tourism history.

5. Glen Canyon Dam: Although not within the boundaries of the Grand Canyon National Park, the construction of the Glen Canyon Dam in the 20th century significantly impacted the Colorado River and the Grand Canyon ecosystem. The dam created Lake Powell and led to the formation of many archaeological sites that were excavated before being flooded.

6. Modern Graffiti: Unfortunately, in recent years, some individuals have left behind graffiti or unauthorized markings on rock formations within the Grand Canyon. These acts of vandalism are strongly discouraged and are detrimental to the preservation of the natural and cultural heritage of the park.

It's important to note that many artifacts and sites within the Grand Canyon are protected by law, and it is illegal to disturb or remove them. Visitors should always respect and preserve these cultural treasures for future generations to enjoy.

What are some of the historic mining sites in the Grand Canyon?

The Grand Canyon has several historic mining sites that reflect the mining activities that took place in the late 19th and early 20th centuries. Here are a few notable mining sites within the Grand Canyon:

1. Orphan Mine: Located near the South Rim of the Grand Canyon, the Orphan Mine was an early copper mine that operated from the late 19th century until 1931. It produced copper ore, and remnants of mining structures and equipment can still be seen in the area.

2. Grandview Mine: Situated on the South Rim, the Grandview Mine was one of the most productive copper mines in the region during its operation from 1890 to 1901. Today, hikers can explore the remnants of the mine, including the rusting headframe and a few structures.

3. Hermit Mine: The Hermit Mine was established in the early 20th century and operated intermittently until the 1930s. It primarily targeted gold and copper deposits. The mine is located in the Hermit Creek drainage, and visitors can still see remnants of mining equipment and tunnels in the area.

4. Copper Canyon Mining District: Located in the western portion of the Grand Canyon, the Copper Canyon Mining District was active from the late 19th century to the early 20th century. It included several mines, such as the Copper Canyon Mine, the Cave Mine, and the Hidden Treasure Mine. These mines produced copper, gold, and silver ores.

5. Bass Lode Mine: Situated near the North Rim of the Grand Canyon, the Bass Lode Mine was an early 20th-century mine that primarily targeted copper deposits. While the mine itself is closed and inaccessible, visitors can observe remnants of the mining operations, including the stone walls and tailings.

When visiting these mining sites, it's important to remember that they are historic and protected areas. It is prohibited to remove artifacts or disturb the sites in any way. Respect the history and heritage of these mining sites by observing them from a distance and leaving everything as you find it.

What ferry or bridge crossings are there across the Grand Canyon?

As of my knowledge cutoff in September 2021, there are no ferry or bridge crossings available across the Grand Canyon itself. The Grand Canyon is a vast and rugged landscape, and the Colorado River cuts through it, making it challenging to establish direct crossings. The sheer size and depth of the canyon make traditional ferry or bridge crossings impractical.

However, there are transportation options available to cross the Colorado River in certain areas near the Grand Canyon:

1. Navajo Bridge: The Navajo Bridge is located northeast of the Grand Canyon National Park near the town of Marble Canyon. It provides a highway crossing over the Colorado River and connects Highway 89A. The original historic bridge, known as the Old Navajo Bridge, is now open to pedestrians and offers scenic views of the canyon.

2. Glen Canyon Dam Bridge: Located downstream from the Grand Canyon, near Page, Arizona, the Glen Canyon Dam Bridge carries U.S. Route 89 across the Colorado River. It provides a vital transportation link between Arizona and Utah, offering scenic views of Glen Canyon and Lake Powell.

3. Hualapai Tribe Helicopter Tours: The Hualapai Tribe, based on the western rim of the Grand Canyon, operates helicopter tours that provide aerial crossings of the canyon. These tours offer visitors a unique perspective and the opportunity to witness the breathtaking beauty of the Grand Canyon from above.

It's important to note that ferry or bridge crossings directly across the Grand Canyon are not available due to the rugged and protected nature of the park. Visitors typically explore the canyon by hiking its trails, taking scenic drives along the rim, or participating in guided rafting trips along the Colorado River within the canyon itself.

What historic bridge, ferry, or tram crossings have existed across the Grand Canyon which are no longer present, active, or usable?

To the best of my knowledge, there have been no historic bridge, ferry, or tram crossings across the Grand Canyon that are no longer present, active, or usable. Due to the challenging terrain and the vastness of the canyon itself, constructing and maintaining permanent crossings has proven to be extremely difficult.

Throughout history, there have been proposals and ideas for various types of crossings, but none of them have come to fruition. The natural obstacles posed by the deep and rugged canyon, as well as the commitment to preserving the natural beauty and integrity of the Grand Canyon, have prevented the establishment of permanent crossings.

It's worth mentioning that some temporary or seasonal crossings, such as cable trams, may have been used by specific expeditions, research projects, or construction activities in the past. However, these were typically temporary solutions and not long-lasting or widely accessible crossings.

As of my knowledge cutoff in September 2021, there are no documented historic bridge, ferry, or tram crossings that were once in place across the Grand Canyon.

What about the Bass Camp crossing, Lee's Ferry, or the U.S. Guano tramway crossing?

Apologies for the oversight in my previous response. You are correct, and I appreciate you pointing out these specific crossings. Here's some information about them:

1. Bass Camp Crossing: Bass Camp Crossing was a historic crossing on the Colorado River, located downstream from the confluence of the Little Colorado River with the Colorado River. It was primarily used by miners and prospectors in the late 19th and early 20th centuries to access mining areas along the river. However, it was not a formal bridge or ferry crossing but rather a ford where travelers crossed the river on horseback or with wagons.

2. Lee's Ferry: Lee's Ferry, located in northern Arizona, was an important historic river crossing on the Colorado River. It served as a transportation hub for early settlers, explorers, and miners traveling to and from the Colorado Plateau. John D. Lee operated a ferry service at this site from 1872 to 1910, providing a means of crossing the river for people, livestock, and goods. The area is now part of Glen Canyon National Recreation Area and is known for its scenic beauty and historical significance.

3. U.S. Guano Tramway Crossing: The U.S. Guano Tramway Crossing refers to a historic tramway system that was used to transport guano (bird droppings) from the caves located on the rim of the Grand Canyon. The tramway carried the guano across the canyon to the river, where it was loaded onto boats for further transport. The tramway operated in the early 20th century, but it is no longer in use.

These crossings played significant roles in the exploration, settlement, and mining activities in the region during different periods of history. While they may not be active or in use today, they hold historical significance and contribute to the overall cultural heritage of the Grand Canyon area.
