The spectacle is so incredible that even Steven Laureys, the neurologist who discovered Mr Houben’s potential, had doubts about its authenticity. He decided to put it to the test.
“I showed him objects when I was alone with him in the room and then, later, with his aide, he was able to give the right answers,” Professor Laureys said. “It is true.”
and
This still seems hard to rationalize with the video footage of the typing occurring while he's apparently asleep. Mrs. Wouters admits the possibility of "tak[ing] over" for him:Mr Houben’s “rebirth” took many painstaking months. “We asked him to try and blink but he couldn’t; we asked him to move his cheek but he couldn’t; we asked him to move his hand and he couldn’t,” Mrs Wouters said.
“Eventually, someone noticed that when we talked to him he moved his toe so we started to try and communicate using his toe to press a button.”
It was a breakthrough but much more was to come when a fellow speech therapist discovered that it was possible to discern minuscule movements in his right forefinger.
Mrs Wouters, 42, was assigned to Mr Houben and they began to learn the communication technique that he is now using to write a book about his life and thoughts. “I thought it was a miracle — it actually worked,” she said.
The method involves taking Mr Houben by the elbow and the right hand while he is seated at a specially adapted computer and feeling for minute twitches in his forefinger as his hand is guided over the letters of the alphabet. Mrs Wouters said that she could feel him recoil slightly if the letter was wrong. After three years of practice the words now come tumbling out, she said.
“The tension increases and I feel he wants to go so I move his hand along the screen and if it is a mistake he pulls back. As a facilitator, you have to be very careful that you do not take over. You have to follow him.”UPDATE (November 25, 2009): Neurologist Steven Novella has weighed in. He suggests that Houben may have recovered some brain function and be conscious, but that the facilitated communication in the videos is positively bogus.
I've noted on the discussion page of Dr. Steven Laureys' Wikipedia entry that the paper in BMC Neurology that purportedly included Houben as a subject claims that all patients in the study were in a minimally conscious state (MCS) but had been misdiagnosed as being in a persistent vegetative state (PVS). The criteria of the study say that those that recovered and emerged from MCS were excluded, which seems at odds with claims that Houben's brain function is "almost normal." A story in Nature 443, 132-133 (14 September 2006) by Mike Hopkin, "'Vegetative' patient shows signs of conscious thought," which quotes Laureys, is about a different patient, in a persistent vegetative state, who showed some signs minimal consciousness. When asked to visualize herself playing tennis, for example, she showed corresponding brain activity. But, as that article noted, that kind of neural response isn't necessarily a sign of consciousness:But what that 'awareness' means is still up for debate. For example, Paul Matthews, a clinical neuroscientist at Imperial College London, argues that the brain imaging technique used cannot evaluate conscious thought; fMRI lights up regions of brain activity by identifying hotspots of oxygen consumption by neurons. "It helps us identify regions associated with a task, but not which regions are necessary or sufficient for performing that task," he says.
Matthews argues that the patient's brain could have been responding automatically to the word 'tennis', rather than consciously imagining a game. He also points out that in many vegetative cases, the patient's motor system seems to be undamaged, so he questions why, if they are conscious, they do not respond physically. "They are simply not behaving as if they are conscious," he says.
Owens counters that an automatic response would be transient, lasting for perhaps a few seconds before fading. He says his patient's responses lasted for up to 30 seconds, until he asked her to stop. He believes this demonstrates strong motivation.
He does admit, however, that it is impossible to say whether the patient is fully conscious. Although in theory it might be possible to ask simple 'yes/no' questions using the technique, he says: "We just don't know what she's capable of. We can't get inside her head and see what the quality of her experience is like."
But then again, as someone who's been reading a lot of literature on automaticity and voluntary action lately, it appears to me likely that a lot of our normal actions are automatic, the product of unconsciously driven motor programs of routine behavior.
Laureys is quoted in the article with a note of skepticism:
"Family members should not think that any patient in a vegetative state is necessarily conscious and can play tennis," says co-author Steven Laureys of the University of Liège, Belgium."It's an illustration of how the evaluation of consciousness, which is a subjective and personal thing, is very tricky, especially with someone who cannot communicate."
The article goes on to note that this woman, who is possibly somewhere between PVS and MCS, "seems to have been much less severely injured than the permanently vegetative Terri Schiavo" (as the report from her Guardian Ad Litem (PDF) made clear).
If Houben is in a minimally conscious state, which he apparently was in order to be included in Laureys' paper that his Wikipedia page says published the Hoeben case in 2009, that appears to contradict news claims that Houben's brain function is "nearly normal," unless he has recovered further function since that paper was written.
UPDATE (November 26, 2009): This footage of Houben and Mrs. Wouters from Belgian (Dutch) state television seems to be the most extensive footage of the facilitation process, and while it starts out looking slightly more plausible, it also clearly shows fairly rapid typing while his eyes are closed (and the camera zooms in on his face).
UPDATE (November 28, 2009): Dr. Laureys and Dr. Novella have had some interaction, which demonstrates that Laureys doesn't get it.
UPDATE (February 15, 2010): Dr. Laureys almost gets it now, and has done additional tests, which have shown that the communications are coming from the facilitator, not Houben.
UPDATE (February 20, 2010): David Gorski at the Science-Based Medicine blog has a bit more from the Belgian Skeptics, who were involved in the test.

I’ve just completed Mike’s Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) and from 1961 for Keith’s to hide the decline.Gavin Schmidt at RealClimate explains:
The paper in question is the Mann, Bradley and Hughes (1998) Nature paper on the original multiproxy temperature reconstruction, and the ‘trick’ is just to plot the instrumental records along with reconstruction so that the context of the recent warming is clear. Scientists often use the term “trick” to refer to a “a good way to deal with a problem”, rather than something that is “secret”, and so there is nothing problematic in this at all. As for the ‘decline’, it is well known that Keith Briffa’s maximum latewood tree ring density proxy diverges from the temperature records after 1960 (this is more commonly known as the “divergence problem”–see e.g. the recent discussion in this paper) and has been discussed in the literature since Briffa et al in Nature in 1998 (Nature, 391, 678-682). Those authors have always recommend not using the post 1960 part of their reconstruction, and so while ‘hiding’ is probably a poor choice of words (since it is ‘hidden’ in plain sight), not using the data in the plot is completely appropriate, as is further research to understand why this happens.In other words, "hiding" in this case is using temperature measurement records instead of tree rings as a proxy for temperature records for a period of time where the tree rings are known not to be an accurate proxy, for whatever reason.
If all of this sounds incompatible with the process of scientific investigation, it shouldn’t. One of the biggest misconceptions the public has about science is that research is a straightforward process of making measurements, and then seeing whether the data support hypothesis A or B. The truth is that the interpretation of data is seldom that simple.
There are all kinds of subjective decisions that must be made along the way, and the scientist must remain vigilant that he or she is not making those decisions based upon preconceived notions. Data are almost always dirty, with errors of various kinds. Which data will be ignored? Which data will be emphasized? How will the data be processed to tease out the signal we think we see?
Hopefully, the scientist is more interested in discovering how nature really works, rather than twisting the data to support some other agenda. It took me years to develop the discipline to question every research result I got. It is really easy to be wrong in this business, and very difficult to be right.
Skepticism really is at the core of scientific progress. I’m willing to admit that I could be wrong about all my views on manmade global warming. Can the IPCC scientists admit the same thing?
Another noteworthy comment, from Real Climate, is this one from caerbannog and Gavin Schmidt's reply:
Just a reminder: CRU is just one of many organizations focusing on climate research. The fact that its director has reacted badly (i.e. appearing to go for the “bunker” mentality) to repeated scurrilous attacks has no bearing on the validity of the science.
Hansen’s approach has been quite different — he’s basically said to his detractors, “here are all of the source code and data — go knock yourselves out”.
Under Hansen, the NASA/GISS data and source code have been freely available on-line for years. And all of the sceptics’ scrutiny of said data has uncovered only one or two minor “glitches” that have had minimal impact.
Just a quick question (or two) to Gavin, if you feel the need to spend even more of your weekend downtime answering questions here.
Given that all of your climate-modeling source-code has been available for public scrutiny for quite a long time, and given that anyone can download and test it out, how many times have climate-model critics have actually submitted patches to improve your modeling code, fix bugs, etc? Have you gotten *any* constructive suggestions from the skeptic camp?
[Response: Not a single one. - gavin]
I think this illustrates that it's far better to be completely open with your data and methods.
UPDATE (November 26, 2009): There's now an official response from the Univ. of East Anglia, the Climate Research Unit, and Phil Jones. Jones notes, regarding the Freedom of Information requests:
We have been bombarded by Freedom of Information requests to release the temperature data that are provided to us by meteorological services around the world via a large network of weather stations. This information is not ours to give without the permission of the meteorological services involved. We have responded to these Freedom of Information requests appropriately and with the knowledge and guidance of the Information Commissioner.UPDATE (December 4, 2009): The journal Nature has weighed in on the controversy.
We have stated that we hope to gain permission from each of these services to publish their data in the future and we are in the process of doing so.
UPDATE (December 11, 2009): PolitiFact gives its analysis of the CRU emails, which is fairly balanced.The key lesson to be learned is that not only must scientific knowledge about climate change be publicly owned — the I.P.C.C. does a fairly good job of this according to its own terms — but the very practices of scientific enquiry must also be publicly owned, in the sense of being open and trusted. From outside, and even to the neutral, the attitudes revealed in the emails do not look good. To those with bigger axes to grind it is just what they wanted to find.
This will blow its course soon in the conventional media without making too much difference to Copenhagen — after all, COP15 is about raw politics, not about the politics of science. But in the Internet worlds of deliberation and in the ‘mood’ of public debate about the trustworthiness of climate science, the reverberations of this episode will live on long beyond COP15. Climate scientists will have to work harder to earn the warranted trust of the public - and maybe that is no bad thing.
But this episode might signify something more in the unfolding story of climate change. This event might signal a crack that allows for processes of re-structuring scientific knowledge about climate change. It is possible that some areas of climate science has become sclerotic. It is possible that climate science has become too partisan, too centralized. The tribalism that some of the leaked emails display is something more usually associated with social organization within primitive cultures; it is not attractive when we find it at work inside science.
It is also possible that the institutional innovation that has been the I.P.C.C. has run its course. Yes, there will be an AR5 but for what purpose? The I.P.C.C. itself, through its structural tendency to politicize climate change science, has perhaps helped to foster a more authoritarian and exclusive form of knowledge production - just at a time when a globalizing and wired cosmopolitan culture is demanding of science something much more open and inclusive.

Philadelphia, PA – 9/4/2009: Grassroots Skeptics today announced the official launch of its website, GrassrootsSkeptics.org. The website is the centerpiece of the group's planned outreach and advocacy in the skeptical community.You can also follow Grassroots Skeptics on Facebook and Twitter.
“There are a lot of passionate advocates and community groups working diligently to advance critical thinking,” said Grassroots Skeptics founder K.O. Myers. “We want to help increase their effectiveness, by making it easier for them to find new members, share resources, and identify methods for getting their message out.”
The group plans to use the site to gather and organize information about skeptical advocacy. At launch, the site will feature an index of local skeptics groups, information on many skeptical blogs and podcasts, discussion forums, and a calendar of skeptical events. The events calendar is a joint project, maintained in collaboration with the prominent skeptical website Skepchick.org.
“There is an amazing amount of information out there that could be helpful for people who want to start or join a skeptical organization,” Myers said. “We want to collect and organize it, to make it more useful for the dedicated individuals who volunteer their time to promote an evidence-based lifestyle.”
“Widespread misinformation about vaccines has lead to a resurgence in preventable illnesses; scam artists posing as 'psychics' prey on the grieving; 'alternative medicine' companies sell billions of dollars of dubious treatments, with almost no government regulation,” said Myers. “Critical thinking is more important than ever, and local skeptics groups are working hard to spread that message. With GrassrootsSkeptics.org, we hope we can make their outreach more effective.”
Future plans for the site include a skeptical speakers' bureau, a searchable map of skeptics groups and skeptic-friendly attractions, and a development kit for skeptics who want to start new groups. “We're excited about this launch,” said Myers, “but we're already looking forward to making GrassrootsSkeptics.org a richer, deeper resource for the organized skeptical community.”
Grassroots Skeptics is a volunteer organization that promotes critical thinking and a reason-centered worldview by helping local skeptics groups to share tools, information and strategies, and connect with skeptical individuals and activists both locally and globally.

Social proof is a simple way for people to decide what actions would be appropriate in a given situation, based off what others like them have done in similar situations, Cialdini said. Those kinds of norms have been very powerful in moving people to conserve energy, recycle and refrain from littering, he said.This morning, I read the following passage in Steven Pinker's The Blank Slate (p. 63):
...Cialdini and his colleagues have recently done research on energy conservation in several hotels in the Phoenix area. The hotel managers allowed Cialdini to place different signs inside hotel rooms and depending on what the signs said, the colleagues were able to significantly increase the willingness of people to hang up their bath towels.
By simply stating that the majority of guests who stay in the hotel hang up their towels at least once during their stay, Cialdini and his colleagues were able to get 28 percent more people to follow that suggestion.
Social psychologists have amply documented that people have a powerful urge to do as their neighbors do. When unwitting subjects are surrounded by confederates of the experimenter who have been paid to do something odd, many or most will go along. They will defy their own eyes and call a long line "short" or vice versa, nonchalantly fill out a questionnaire as smoke pours out of a heating vent, or (in a Candid Camera sketch) suddenly strip down to their underwear for no apparent reason.Here, Pinker is referring to the Asch conformity experiments. He notes that there are two reasons for this kind of imitative behavior, "to benefit from other people's knowledge and judgment" and "the desire to follow the norms of a community."
... the modern world is one of strident cultural diversity, where you are constantly made aware that people live in different circumstances, have different values, worship other gods, have different rituals. ... fundamentalists want to return to a (largely mythical) past when local values and identity were taken for granted, when no one was aware that there were other ways of living. (p. 293)This could also explain the creation of distinctly Christian media (music, books, clubs and groups arranged around particular interests offered by megachurches) offered as a substitute for their secular counterparts, as a mechanism to insulate believers from contrary ideas. By keeping the believer in a community that is, at least to some extent, isolated from the broader world, the danger is reduced that a believer will be exposed to alternative views and practices which he might be likely to imitate through peer pressure, social proof, or social conformity.

Inspired by the annual The Open Laboratory, the Skeptical Blog Anthology is a printed anthology of blog posts voted the very best of 2009, managed by the Young Australian Skeptics in conjunction with the Critical Teaching Education Group (CTEG). The anthology is an attempt to bring a greater awareness of the skeptical content on blog sites and showcase some of the range and diversity in the blogosphere.There's a submission form at the Young Aus Skeptics website.
With an aim to provide text-based resources to classes and readers who may be interested or intrigued by what skepticism has to offer, entries from January 1st to December 1st 2009 are eligible for submission. Both a print and Portable Document Format (pdf) will be made available for purchase via Lulu.com, with estimated printing early in 2010.
Entries can be self-nominated or proposed by readers of skeptical blog sites. The guidelines proposed by the popular Skeptics’ Circle are a fine indicator of the kind of content suitable for the anthology, including urban legends, the paranormal, quackery, pseudoscience, intelligent design, historical revisionism, critical thinking, skeptical parenting/educating skeptically, superstitions, etc.

Hi out there...now I know why Banacheck was "the card handler". I have been cheated. I did find the right cards. And there is one more thing. At the stage, Banacheck said to me BEFORE he even looked in the envelope I had cut...and here is spade ace, the one you looked for!!!! I first hit me now about that ....but maybe you can see it yourself if someone get the video. I don`t care about the money, that wasn`t the reason why I came. So no matter what you think out there......I was CHEATED!!!!!It was a typical response to the Randi challenge from an honest proponent of a claim who doesn't understand why the claim failed under test conditions, resolving the cognitive dissonance by placing blame on the experimenter.
