Jonah Lehrer's Blog

Apologies for the light blogging: I'm enjoying a little vacation from my computer. But here is a recent little article about willpower in the WSJ:

Willpower, like a bicep, can only exert itself so long before it gives out; it's an extremely limited mental resource.

Given its limitations, New Year's resolutions are exactly the wrong way to change our behavior. It makes no sense to try to quit smoking and lose weight at the same time, or to clean the apartment and give up wine in the same...

My latest Wired article is now online and on the newsstands. It's about the messiness of experimental science, the blind-spots created by knowledge, Thorstein Veblen, European Jews and the background static created by the Big Bang.

Earlier this week, I wondered if all of our new knowledge about the brain, which is too often presented in a lazy causal fashion - if x lights up, then y - might undermine our sense of self and self-control. I've since riffled through the literature and found some interesting answers.

The first study was done by Kathleen Vohs and Jonathan Schooler. The experiment itself was simple: a group of undergraduates was given two excerpts from Francis Crick's The Astonishing Hypothesis. The first...

James Surowiecki has the smartest take I've read on the Woods sex scandal:

Woods's appeal was based, ultimately, not on his physical abilities but on his mental toughness, his extraordinary capacity for focus and discipline. He was the man who always made the key putt, who never cracked under pressure. That's why Gatorade, introducing a new drink with his face on the label, called the drink Tiger Focus. And it's why the most powerful Nike ad about him is the one in which his father, in a...

The always fascinating Ed Yong, over at Not Exactly Rocket Science, highlights a recent study on testosterone, aggression and the placebo effect.

If ever a hormone was the subject of clichés and stereotypes, it is testosterone. In pop culture, it has become synonymous with masculinity, although women are subject to its influence too. Injections of testosterone can make lab rats more aggressive, and this link is widely applied to humans. The media portrays "testosterone-charged" people as...

I recently learned that many professional graduate schools - law schools, business schools, even medical schools - continue to provide "test accommodations" to students with attention deficit hyperactivity disorder, or ADHD. These accommodations usually take the form of extra time on the exam, when time is a crucial resource.

Of course, it's not just grad schools who are struggling with the question of how to treat students with ADHD. Princeton is currently embroiled in a lawsuit:

A...

The latest McSweeney's production is a marvel. It's in the form of a daily newspaper - The San Francisco Panorama - and is yet another reminder that the newspaper remains an essential literary form, a potent mixture of breaking news and obscure stories. (If your local indie bookstore stocks the Panorama, be sure to buy a copy.) I was fortunate enough to write for the Panorama Magazine on the cognitive benefits of travel, which I've pasted in below.

It's 4:15 in the morning, and my alarm...

In the latest Mind Matters, Adam Waytz (an old college friend, co-author of my favorite book on basketball, The Macrophenomenal Pro Basketball Almanac, and now a post-doc at Harvard) writes about a fascinating new paper by PJ Henry on social status and aggression. If you've read Gladwell's excellent Outliers, then you're probably familiar with the work of Richard Nisbett and Dov Cohen. They argued, in an influential series of papers, that landscapes more conducive to herding were more likely ...

I found this minor anecdote, from Peter Baker's authoritative NY Times article on Obama's decision-making process for Afghanistan, to be quite fascinating:

On Oct. 9, Mr. Obama and his team reviewed General McChrystal's troop proposals for the first time. Some in the White House were surprised by the numbers, assuming there would be a middle ground between 10,000 and 40,000.

"Why wasn't there a 25 number?" one senior administration official asked in an interview. He then answered his own...

Jon Stewart on the stolen Climategate emails:

I have two responses to the release of these admittedly unflattering emails. Firstly, they shed virtually no light on the actual climate science. Tyler Cowen says it best:

I see science, including climate science, as very much a decentralized process, based on the collective efforts of thousands of researchers. The evidence for our current understanding of climate change also comes from a wide variety of disciplines, including chemistry...
