The debate over vaccination is raging (c.f. Wired article) and it smacks of one of those conundrums that is unlikely to get resolved by scientific inquiry.  I offer the following hypothesis and a way out of the dilemma. Hypothesis: Vaccination is something that is good at the societal level but bad at the...

Via the indispensable Tyler Cowen, a new paper from Johnson and Fowler explores whether overconfidence is, in fact, adaptive. They show that it it is under some very reasonable assumptions.  They model competition for resources as a two-player game and then analyze the evolutionary dynamics of populations...

In listening to this account of Hemant Lakhani, convicted in 2005 of illegal arms dealing, I was reminded of another This American Life episode about Brandon Darby.  Underlying both stories are accounts of seemingly incompetent, misguided, would-be bad guys who were actualized on a path of evildoing by...

The old philosophical theory says that reason is conscious, can fit the world directly, is universal (we all think the same way), is dispassionate (emotions get in the way of reason), is literal (no metaphor or framing in reason), works by logic, is abstract (not physical) and functions to serve our...

Here is a fascinating discussion on NPR's Forum from earlier this year on the subject of mercury and fish: [audio:http://www.kqed.org/.stream/anon/radio/forum/2009/02/2009-02-26b-forum.mp3] If you've listened to this the whole way through (which you should), I'm curious as to how it will affect your...

What's fascinating to me about this is not that it works so well and or that there might actually be support in the Obama administration for doing it on a national scale, but rather that there has not been a backlash against it yet.  What are the odds that something like this will actually get implemented?...

Thanks to a pointer from Sandeep Baliga over at Cheap Talk, I recently Kindled Matthew Alexander's How to Break a Terrorist. If this were a novel, it would be in the top 10% of thrillers I've read in the last 5 years.  But it's a true story. Alexander (a pseudonym) is an Air Force interrogator with a...

As I mentioned in this post, one of the three primary planks of my worldview is that, "...the human brain is a woefully inadequate decision making substrate." I started adopting this posture in graduate school and have refined it with constant input from the cognitive psychology and neurobiology literature...

This is one of the most important medical "breakthroughs" in recent memory.  You should read the entire article, because it makes some subtle points, but the upshot is that placebo has (at least) two components, one that is triggered by conscious belief in a putative cure, and another that is triggered by...

Debbie Maier asks us on the Upcoming Topics page to address Crohn's Disease. I don't know too much about it except that it's an autoimmune disease and has a complex, multi-causal etiology and pathology.  In my reading on autoimmune diseases in general there seems to be a direct link between latitude an...

Kevin just posted about a great article by Felix Salmon in Wired.  I underlined three quotes in my reading of it: "Correlation trading has spread through the psyche of the financial markets like a highly infectious thought virus."

Until recently, Artificial Intelligence research has been grounded on a theory of cognition that is based on symbolic reasoning.  That is, somewhere in our heads the concepts are represented symbolically and reasoned about via deduction and induction. At long last, AI researchers are truly learning from...

By all accounts, the ability to empathize with others is the hallmark of social behavior.  Indeed, when we come across those rare individuals whom we view as anti-social, or those even more rare individuals that we label as sociopaths, the diminished or missing feature of their personality is...

Arnold Kling blogs about a recent video discussion between Robin Hanson and Will Wilkinson.  I commented on one of the points Arnold picked out of the debate and then realized that I could construct a matrix of epithets based on my analysis.  As it involves evolutionary psychology, I thought some of you...
