"Where is my mind? The question - memorably posed by rock band the Pixies in their 1988 song - is one that, perhaps surprisingly, divides many of us working in the areas of philosophy of mind and cognitive science. Look at the science columns of your daily newspapers and you could be forgiven for thinking that there is no case to answer. We are all familiar with the colorful "brain blob" pictures that show just where activity (indirectly measured by blood oxygenation level) is concentrated as we attempt to solve different kinds of puzzles: blobs here for thinking of nouns, there for thinking of verbs, over there for solving ethical puzzles of a certain class, and so on, ad blobum. (In fact, the brain blob picture has seemingly been raised to the status of visual art form of late with the publication of a book of high-octane brain images. ) There is no limit, it seems, to the different tasks that elicit subtly, and sometimes not so subtly, different patterns of neural activation. Surely then, all the thinking must be going on in the brain? That, after all, is where the lights are. As our technologies become better adapted to fit the niche provided by the biological brain, they become more like cognitive prosthetics. But then again, maybe not. We've all heard the story of the drunk searching for his dropped keys under the lone streetlamp at night. When asked why he is looking there, when they could surely be anywhere on the street, he replies, "Because that's where the light is." Could it be the same with the blobs?"

"The behavioral revolution in economics and psychology has successfully identified and named close to three dozen biases (my favorite behavioral folk song defines them in verse). I had thought that these biases transcended issues of culture. Indeed, both neoclassical and behavioral economists were united in a belief that cultural variables were of secondary importance when it came to the deep drivers of behavior. But a series of experiments now has me thinking that the underlying heuristics are less universal."

"Here's a little ditty that catalogs and musically explains a useful list of cognitive biases uncovered by behavioral psychologists. It was created by Bradley Wray, a high school teacher in Maryland, as a study aid for students preparing for their AP Psychology exam. How are you biased? Let Bradley Wray count the ways."

I think I've linked this one already, but it's good enough to list twice!

"When you take a sip of Cabernet, what are you tasting? The grape? The tannins? The oak barrel? Or the price? Believe it or not, the most dominant flavor may be the dollars. Thanks to the work of some intrepid and wine-obsessed economists (yes, there is an American Association of Wine Economists), we are starting to gain a new understanding of the relationship between wine, critics and consumers."

Thanks to Felix (TAS2010) for passing this one on!

"In the past few weeks, the blogosphere has been abuzz about the dangers of non-replication and the "decline" effect, triggered by Jonah Lehrer's interesting piece in the New Yorker (mostly behind a firewall). The central claim in the piece is that initially strong or provocative findings diminish in strength over time. The decline might well come from more stringent methodology or better experimental controls rather than via mysterious forces, but that's not what concerns me today. My concern is about media reporting and even blogging about new and provocative scientific findings, the very findings that tend to decline. Following a murder, the arrest of a suspect is broadcast on the front pages, but when that suspect is exonerated, the correction ends up on the back of the local section months later (if it appears at all). The same problem holds for flawed scientific claims. The thoroughly debunked Mozart Effect still receives media coverage, just as other unsupported findings remain part of the popular consciousness despite a lack of replicability."

"Gift-giving makes economists crazy. It's so inefficient! So we wondered: Is there a way to make the holiday season both more efficient and more joyful? On today's Planet Money, we try to answer that question by conducting a wildly unscientific experiment. We go into a seventh-grade classroom and give a bunch of kids some small gifts - candy, raisins, fig newtons. Then we ask them how much they value what they got, and if they can think of a way to make everyone better off, without buying any more gifts. They quickly arrive at a solution: trade. Behold, the power of economics!"

This is the better version.

"There's a tiny island called Yap out in the Pacific Ocean. Economists love it because it helps answer this really basic question: What is money? There's no gold or silver on Yap. But hundreds of years ago, explorers from Yap found limestone deposits on an island hundreds of miles away. And they carved this limestone into huge stone discs, which they brought back across the sea on their small bamboo boats. It's unclear if these stones started as money. But at some point the people on Yap realized what most societies realize. They needed something that everyone agrees you can use to pay for stuff. And like many societies, the people of Yap took the thing they had that was pretty - their version of gold - and decided that was money."

An interesting exploration of the definition of the word "money".

"Giving and receiving gifts can be a joyful thing - unless you're an economist. From an economic perspective, all those books that will never be read and ties that will never be worn are a huge waste."

"UPDATE: Fox News senior vice president for news Michael Clemente has responded to the study which found that his network's viewers are more misinformed about American political issues than any other channel. In a statement to the New York Times' Brian Stelter, Clemente disparaged the University of Maryland, where the study was done. "The latest Princeton Review ranked the University of Maryland among the top schools for having 'Students Who Study The Least' and being the 'Best Party School' - given these fine academic distinctions, we'll regard the study with the same level of veracity it was 'researched' with," Clemente said."

The Fox News VP responds to the study of FoxNews viewers misinformation status by making a textbook ad hominem on the university making the study, University of Maryland.

"AS hundreds of thousands of students rush to fill out college applications to meet end-of-the-year deadlines, it might be worth asking them: Is where you spend the next four years of your life that important? Harvard can give you advantages, but not everything. The sluggish economy and rising costs of college have only intensified questions about whether expensive, prestigious colleges make any difference. Do their graduates make more money? Get into better professional programs? Make better connections? And are they more satisfied with their lives, or at least with their work?"

Think we all have dif­fer­ent tastes where beauty is con­cerned? Well, cog­ni­tive psy­chol­ogy shows us that an aver­age face (made from sev­eral other faces) is almost always judged as more attrac­tive than its con­stituent faces… Why? It may be for the sim­ple rea­son that an aver­age face is closer to the men­tal idea we have of a pro­to­typ­i­cal face and thus eas­ier for the brain to process. Want to expe­ri­ence it? Fol­low this link to the the Face Research Lab and cre­ate your own aver­age faces. Enjoy.

"In recent years popular science writing has bombarded us with titillating reports of discoveries of the brain's psychological prowess. Such reports invade even introductory patter in biology and psychology. We are told that the brain - or some area of it sees, decides, reasons, knows, emotes, is altruistic/egotistical, or wants to make love. For example, a recent article reports a researcher's "looking at love, quite literally, with the aid of an MRI machine." One wonders whether lovemaking is to occur between two brains, or between a brain and a human being. There are three things wrong with this talk."

"Lies, Damned Lies, and Medical Science Much of what medical researchers conclude in their studies is misleading, exaggerated, or flat-out wrong. So why are doctors-to a striking extent-still drawing upon misinformation in their everyday practice? Dr. John Ioannidis has spent his career challenging his peers by exposing their bad science."

"Guy Deutscher is that rare beast, an academic who talks good sense about linguistics, his chosen field. In his new book, Through the Language Glass (Heinemann), he fearlessly contradicts the fashionable consensus, espoused by the likes of Steven Pinker, that language is wholly a product of nature, that it does not take colour and value from culture and society. Deutscher argues, in a playful and provocative way, that our mother tongue does indeed affect how we think and, just as important, how we perceive the world. An honorary research fellow at the University of Manchester, the 40-year-old linguist draws on a range of sources in the book to show language reflecting the society in which it is spoken. In the process, he explains why Russian water (a "she") becomes a "he" once you have dipped a teabag into her, and why, in German, a young lady has no sex, though a turnip has."
