Everybody needs a good placebo to get them through the day. For Behavioral economist and Predictably Irrational author Dan Ariely, it used to be Airborne. Even though he was mainly sure it didn’t work, that faint glimmer was enough to keep him taking it and cold-free. Then he read new studies that said it was totally placebo. His placebo stopped working thereafter. Luckily, his mom has sent him a new placebo! And he feels right as rain. What’s your favorite placebo? [via BoingBoing] [More]
