Witch Hunter Sues BHA

The British Humanist Association has announced that they are being sued by notorious Nigerian “witch hunter”, Helen Ukpabio, for half a billion pounds for alleged libel. The only reasonable response to this situation, in my opinion, is to magnify the criticism of Ukpabio as much as possible.

For those who are not aware, I am also being sued for expressing my critical opinions. You can read the full details here. I have always supported my fellow skeptics in the past when they faced being silenced through legal intimidation, but now I have to disclose that I have a personal connection to this issue as well.

In any case – Ukpabio, in my opinion, represents an extreme version of the harms that result from abject superstition. She considers herself (or at least claims to) a “Lady Apostle” and makes a career out of exorcising children she believes are possessed by spirits.

The basis of her suit is particularly absurd. She claims that she exorcises children “possessed with black, red and vampire witchcraft spirits” and that the BHA ...

The Seven Step Method to Better Meetings

Notes designed by Ema Dimitrova from the Noun Project

Notes designed by Ema Dimitrova from the Noun Project

Brainstorming meetings can be disastrous, often eating up time and leading to poor decisions. Google Ventures has a way to avoid the pain of traditional meetings with a seven step method.

Over at Fast Company, Jake Knapp explains:

The next time you need to make a decision or come up with a new idea in a group, call timeout and give the note-and-vote a try.

1. Note: Distribute paper and pens to each person. Set a timer for five to 10 minutes. Everyone writes down as many ideas as they can…

2. Self-edit: Set the timer for two minutes. Each person reviews his or her own list and picks one or two favorites…

3. Share and capture: One at a time, each person shares his or her top idea(s). No sales pitch. Just say what you wrote and move on…

4. Vote: Set the timer for five minutes. Each person chooses a favorite from the ideas on the whiteboard…

5. Share and capture: One at ...

DARPA explores neuromodulation of organ functions to help the human body heal itself

DARPA ElectRx (credit: DARPA)

DARPA’s new Electrical Prescriptions (ElectRx)  (pronounced “electrics”) program aims to develop new high-precision, minimally invasive technologies for modulating nerve circuits to restore and maintain human health, initiated in support of the President’s brain initiative.

“The technology DARPA plans to develop through the ElectRx program could fundamentally change the manner in which doctors diagnose, monitor and treat injury and illness,” said Doug Weber, DARPA program manager. “Instead of relying only on medication, we envision a closed-loop system that would work in concept like a tiny, intelligent pacemaker. It would continually assess conditions and provide stimulus patterns tailored to help maintain healthy organ function, helping patients get healthy and stay healthy using their body’s own systems.”

ElectRx technologies are also expected to help accelerate scientific research aimed at achieving a more complete understanding of the structure and function of specific neural circuits and their role in health and disease.

Potential targets include recently identified circuits involved in regulating immune system function. This could providing new hope for treating a range ...

Causal Analysis in Theory and Practice

In Defense of Unification (Comments on West and Koch’s review of *Causality*)

A new review of my book *Causality* (Pearl, 2009) has appeared in the Journal of Structural Equation Modeling (SEM), authored by Stephen West and Tobias Koch (W-K). See http://bayes.cs.ucla.edu/BOOK-2K/west-koch-review2014.pdf

I find the main body of the review quite informative, and I thank the reviewers for taking the time to give SEM readers an accurate summary of each chapter, as well as a lucid description of the key ideas that tie the chapters together. However, when it comes to accepting the logical conclusions of the book, the reviewers seem reluctant, and tend to cling to traditions that lack the language, tools and unifying perspective to benefit from the chapters reviewed.

The reluctance culminates in the following paragraph:
“We value Pearl’s framework and his efforts to show that other frameworks can be translated into his approach. Nevertheless we believe that there is much to be gained by also considering the other major approaches to causal inference.”

W-K seem to value my “efforts” toward unification, but not the unification itself ...

A brief history of psychedelic psychiatry | Mo Costandi

In the 1950s a group of pioneering psychiatrists showed that hallucinogenic drugs had therapeutic potential, but the research was halted as part of the backlash against the hippy counterculture.

This article appears in the September 2014 issue of The Psychologist magazine and has been republished here with permission from the editors. The whole issue is devoted to the use of hallucinogenic drugs in therapy and research, and is freely available online.

On 5th May, 1953, the novelist Aldous Huxley dissolved four-tenths of a gram of mescaline in a glass of water, drank it, then sat back and waited for the drug to take effect. Huxley took the drug in his California home under the direct supervision of psychiatrist Humphry Osmond, to whom Huxley had volunteered himself as a willing and eager guinea pig.

The Unpersuadables

We would like to believe people are rational. We would like to believe that if they have formed a false belief based on inaccurate information and poor reasoning, they will change that belief when they are provided with accurate information and better reasoning. We are frequently disappointed.

An Example of What Should Happen:

I recently talked with a college professor who believed chiropractic treatment could lower blood pressure. His belief was based on a media report of a chiropractic study. He thought it was plausible that neck manipulation could somehow relieve obstructions to blood flow to the base of the brain, thereby somehow correcting the cause of high blood pressure. I told him that rationale was anatomically and physiologically implausible. I pointed out that the researchers used NUCCA,  a form of manipulation that is rejected by most chiropractors. He did not know what NUCCA was. I provided him with information, including links to the study itself and to chiropractor Sam Homola’s excellent critique of the study.  My friend changed his mind and thanked me ...

Looking Back at a Year (Almost) Without English

A few days ago I came back to Vancouver, marking the end of this project Vat and I started over a year ago. Together we lived in Spain, Brazil, China and Korea, all while trying to speak as little English as possible.

In this post, I’m going to recap the successes and stumbles of the project, along with what I think it means for travel and language learning.

Side note: I haven’t forgotten about the final update for Korea. I was hoping on releasing that article first, but we hit some delays editing the interviews, so I’m switching the order and putting this one first.

Was the Project a Success?

There were three dimensions of success I was interested in throughout the project. The first, was simply how well we avoided speaking English—the namesake and primary constraint of the project. Second, what level did we reach in each language? Finally, what was the overall experience of travel, did not speaking English improve the journey?

Krishnamurti on The Singularity

A couple of videos of Jiddu Krishnamurti talking about artificial intelligence and the future of humanity have come to my attention and I thought they might also be of interest to h+ Readers.

Screen Shot 2014-09-01 at 9.16.11 AM“Jiddu Krishnamurti (12 May 1895 – 17 February 1986) was a speaker and writer on philosophical and spiritual subjects. In his early life he was groomed to be the new World Teacher but later rejected this mantle and disbanded the organisation behind it. His subject matter included psychological revolution, the nature of mind, meditation, inquiry, human relationships, and bringing about radical change in society. He constantly stressed the need for a revolution in the psyche of every human being and emphasised that such revolution cannot be brought about by any external entity, be it religious, political, or social.”

Where Do You Fall on the Creativity Spectrum?

The Creativity Spectrum from Kevan Lee at Buffer

We often hear the advice “just start,” but it comes without a clear explanation as to how. Visualizing the gap between mediocre and great work in this way makes it evident that the only way to get on that scale is to overcome the bigger gap between nothing and something.

Over at Buffer, Kevan Lee gives us an answer by taking creative author Shirky’s notes to create The Creativity Spectrum.:

What holds you back from creating something?

For many of us, it’s fear. Fear that something might not be good enough, unique enough or novel enough.

Overcoming this fear is a huge and important step… Author Clay Shirky noted the importance of the simple act of creating—creating anything, even a silly thing—in his book Cognitive Surplus: “The stupidest possible creative act is still a creative act. On the spectrum of creative work, the difference between the mediocre and the good is vast. Mediocrity is, however, still on the spectrum; you can move from ...

Surviving Statistics

How the survivor bias distorts reality
magazine cover

When I purchased my latest vehicle, I was astonished to get the license plate 6NWL485. What are the chances that I would get that particular configuration? Before I received it, the odds would have been one in 175,760,000. (The total number of letters to the power of the number of letters on the plate times the total number of digits to the power of the number of digits on the plate: 263 x 104). After the fact, however, the probability is one.

This is what Pomona College economist Gary Smith calls the “survivor bias,” which he highlights as one of many statistically related cognitive biases in his deeply insightful book Standard Deviations (Overlook, 2014). Smith illustrates the effect with a playing card hand of three of clubs, eights of clubs, eight of diamonds, queen of hearts and ace of spades. The odds of that particular configuration are about three million to one, but Smith says, “After I look at the cards, the probability of having ...

People sometimes confuse me with Scott Aaronson because of our similar-sounding names. I encourage this, because Scott Aaronson is awesome and it can only improve my reputation to be confused with him.

But in the end, I am not Scott Aaronson. I did not write Quantum Computing Since Democritus. To be honest, I wasn’t really even able to understand Quantum Computing Since Democritus. I knew I was in for trouble when it compared itself to The Elegant Universe in the foreword, since I wasn’t able to get through more than a few chapters of that one. I dutifully tried to do the first couple of math problems Democritus set for me, and I even got a couple of them right. But eventually I realized that if I wanted to read Democritus the way it was supposed to be read, with full or even decent understanding, it would be a multi-year project, a page a day or worse, with my gains fading away a few days after I made them into a cloud of ...

Privacy vs Omniveillance

Media discussions of privacy, freedom and the information age are starting to get more interesting, as folks finally start to realize a core truth... that everything eventually leaks. That the reflex of whining and demanding shadows to hide-in will never work. The data we entrust to banks and retail chains?  The trade secrets that companies rely on for competitive advantage? The cherished spy programs of our governmental professional protector caste (PPC)? If these do not leak because of hackers, or accidents, then would-be (or self-styled) whistle-blowers will see to it, sooner or later.

It has long been pointed out that information is not like other commodities.  It can duplicate itself at virtually zero cost, and those copies can escape even without you noticing it's happened.  That is Fact Number One. Everything eventually leaks.


Fact number two is one I've tried to point out for decades.  That this is fundamentally a clash of values and civilizations.  The Western Enlightenment (WE) has always been the rebel and underdog, versus the 99% standard human (and zero-sum ...

There’s a Reason They Call Him “Amazing”

The Miami Herald‘s Glenn Garvin had a wonderful profile of James Randi in yesterday’s paper:

Hesitantly, I wondered aloud whether what the mediums were doing was really so bad, if it wasn’t simply bargain-basement psychological counseling. Letting heartbroken children think that the spirits of their dead parents live on and are happy, in return for a few dollars? Helping them let go and move on, is that so wrong?

“It’s wrong because it’s never just a few dollars, they’ll continue to spend money,” insisted Randi. “They’ll want to know more, talk more. But the message will never get beyond ‘I’m here and I’m fine.’ If you ask mom’s spirit a question like, ‘Where did you leave the will?’ you’ll never get an answer like ‘It’s behind the kitchen cabinet.’ Instead, it’ll be ‘Oh, golly, honey, I have to go now.’ Because the medium can’t answer it…

If you are like most people, the relative status of fields A and B will likely influence your choice. If the other field has higher status than yours, you are more likely to be cautious, while if the other field has lower status than yours, you are more likely to speculate more freely. In both cases your subconscious will have made good guesses about the likely status consequences to you if an expert in B were to speak up and challenge your speculations.

How To Detect Fictional Evidence

Based On: The Logical Fallacy of Generalization from Fictional Evidence

Some fictional evidence is explicit – “you mean the future will be like Terminator?”. But it can also be subtle. Predicting the future can be done “in storytelling mode”, using the tropes and methods of storytelling, without referring to a specific fictional universe like the Matrix; one obvious example is Hugo de Garis. How can we tell when “predictions” are just sci-fi, dressed up as nonfiction?

1. The author doesn’t use probability distributions.

Any interesting prediction is uncertain, to a greater or lesser extent. Even when we don’t have exact numbers, we still have degrees of confidence, ranging from “impossible under current physics” through to “extremely likely”. And many important predictions can be done as conditionals. We may have no idea how likely event B is, but we might be able to say it’s almost certain to follow event A.

But stories aren’t like that. An author creates an “alternate world”, and any given fact (“Snape kills Dumbledore!”) is either true or ...

Pritchard on pragmatics of knowledge ascriptions

I'm working on a review of Duncan Pritchard's book Epistemological Disjunctivism. I'll probably try out a few ideas here over the next couple of months. I want to start out by focusing on something from near the end of the book—§8 of Part III. Here, Duncan is trying to deal with what he considers to be a challenge to the particular form of neo-Moorean disjunctivist response to the skeptical paradox he's been developing. The salient element of the view is that, contrary to skeptical intuitions, one does typically know that e.g. one is related in the normal way to the world, rather than being a brain in a vat. This, even though one lacks the ability to discriminate perceptually between being related in the normal way to the world and being a brain in a vat.

The challenge Duncan considers in this section is that Moorean assertions like "I know I'm not a brain in a vat" seem conversationally inappropriate. As he puts it earlier in the book ...

Imagine making a picture using film so insensitive to light – so slow, in photographic parlance – that to burn an image onto it required an exposure of twenty-five centuries.

It would be a world where plants and people, seasons and civilizations, had come and gone, quite untouched, and unbothered, by mankind. And yet, here it is, a world, unmistakably shaped by human hands.

Perhaps one of humanity’s greatest weaknesses is that our power of imagination tends to be dwarfed by our power of transformation. Twenty-five centuries ago, Rome was little more than a small town; Confucius had just resigned from his government post; Olmec society had slid into decline; and none of the languages we speak today had yet evolved.

Study: Fish Oil Prevents Brain Shrinkage and Cognitive Decline in Older Adults

Three more cases of Alzheimer’s disease will have been diagnosed by the time you finish reading this article. More than 5 million people have Alzheimer’s in the United States alone (44 million worldwide), and the rate of new diagnosis is about one patient every minute, with no cure on the horizon. Now a new study adds evidence to the argument that fish oil supplementation could be one of the best preventives we have against the disease--at least for people not at genetic risk of developing it.

Researchers from Rhode Island Hospital studied three groups of older adults, ages 55-90, using neuropsychological tests and brain magnetic resonance imaging (MRI) every six months. The group included 229 adults with no signs of the disease; 397 who were diagnosed with mild cognitive impairment; and 193 with Alzheimer’s. All participants were part of the Alzheimer’s Disease Neuroimaging Initiative (ADNI), which began in 2003 and ended in 2010.

Results showed that adults taking fish oil, who had not yet developed Alzheimer’s, experienced significantly less cognitive ...

Handwritten Notes Lead to Better Learning

In response to the trend to abolish teaching of cursive in schools, about a year ago I posted an article on what I thought were the developmental benefits of handwriting (http://www.psychologytoday.com/blog/memory-medic/201303/why-writing-hand-could-make-you-smarter). That post has generated over 230 comments.

Now there is evidence that handwriting of lecture notes, compared to typing on a laptop, improves learning by college students. Following up on prior studies that indicated relative ineffectiveness of taking notes by laptop, researchers Pam Meuller and Daniel Oppenheimer provide clear evidence that handwritten note-taking produces better learning in college students.

They reported three experiments that compared the efficacy of college students taking notes by handwriting or with a lap top. Those who used handwritten notes that they studied later scored significantly higher than students using laptops, including fleet typists who took vastly more copious notes. Handwriters took fewer notes overall with less verbatim recording. There are many possible explanations, beginning with the "less is more" idea in which too much information produces cognitive overload. Notably, when the typing ...

Unbeknownst to the casual reader perhaps, the role of science fiction in society has changed to some extent over this period of time, with new styles, mediums and subgenres developing, each with differing goals and appeals.

Exploring possible future technologies and their implications is only one aspect of the science fiction genre, but in regards to this facet writer and futurist Dr. Thomas Lombardo has said that science fiction speaks to the total person about the future, believing that it resonates with all the fundamental dimensions of the human mind and human experience.

Meet the mother and father of cognitive neuroscience | Mo Costandi

Independently and almost single-handedly, husband and wife Uta and Chris Frith have transformed the way we view autism and schizophrenia.

Chris Frith sits at the kitchen table in his northwest London home, cutting slices of smoked salmon into irregularly-shaped pieces and then placing them in a meticulous tiling pattern onto pieces of buttered brown bread.
