Once more, the team from the Annals of Improbable Research handed out another year’s Ig Nobel Prizes last week. From the New Zealand team who got the Economic Prize for their research determining how to market things to rocks, to The Medical Prize winners who discovered that if the left side of your body itches and you look in a mirror and scratch the right side of your body the itching is relieved, this years winners share a trait in common with each other and all previous winners. First they make you laugh… and then they make you think. Mostly about how gullible some grant organizations may be, but every so often about the real-world problem that inspired the research in the first place. This is probably my favorite annual award in the world of Science.
