My son was underperforming at school, and I was gently encouraging him to try harder (if gesticulating like an over caffeinated Italian qualifies as gentle encouragement). He could not understand why I was upset: “Dad, most of my friends are doing drugs and engaging in unprotected sex. You should be rewarding me for being such…
Lots of us eat when we are stressed. But did you know that even when we are not currently under stress, the amount of food we eat might be influenced by the stress we experienced as children? That’s the conclusion Sarah Hill, a psychologist at TCU, wants us to draw from several studies she ran…
Put our brains into the modern food environment, and you have a recipe for disaster. Our brains are hardwired to crave calorie-dense foods, this craving no doubt arising from our evolutionary time spent on the Tundra where calories were often scarce. But our modern food environment surrounds us with calorie-dense foods, forcing us to deplete…
It is notoriously difficult to change physician behavior. When it’s discovered that primary care physicians are, say, prescribing too few cholesterol pills or too many antibiotics, it will not be easy to change those behaviors. Physicians are strong-willed people, with lots of things competing for their attention and with many well ingrained habits. That’s why…
Here is a great graphic from the Center for Science in the Public Interest laying out how supermarkets lay out food to encourage impulse purchases: So much for “free” markets!
Very interesting article in the Lancet recently, from the nudge unit in the United Kingdom. They give physicians feedback on how much they prescribed antibiotics compared to their peers, and found that such feedback reduced antibiotic prescriptions. I hope to see more of this work!
I have absolutely no confidence that this approach will work, but I don’t even care because it is so hilarious. Thanks to Pelle Hansen (@Peguha) for tweeting this image.
I recognize that correlation does not prove causation. But here is a picture illustrating the correlation between income inequality and the percent of a country’s population that is obese. The findings are provocative, to say the least. Making the relationship somewhat plausible is all the evidence we have now of the toll that income inequality…
Pizza is pizza, and a full stomach is a full stomach. But when restaurants slice pizza into smaller pieces, you are probably likely to consume less pizza:
I love behavioral science. I love public policy. And I am obsessed with music. So you can see why I think the nudge pictured below may be the coolest thing on the planet! It encourages drivers to drive at an appropriate speed, so they can hear music created by their passage over the road: I…
