The Monty Hall problem: going with your gut will get your goat

By Adrian Dudek

Suppose you’re on a game show, and you’re given the choice of three doors. Is it to your advantage to switch your choice?

The game show host adjusts his bow tie and flashes you an oh-so-wicked smile as he brings your attention to three closed doors.

By John Cook

John Cook set out to debunk two climate myths by exploiting the psychology of misinformation.

Debunking myths requires an understanding of the psychological research into misinformation. But getting your refutation out in front of lots of eyeballs is a whole other matter.

Lies, Damn Lies, and Science

By Stephan Lewandowsky, Gilles Gignac & Klaus Oberauer

Prince Phillip runs the world drug trade, the 9/11 attacks in the US were an “inside job” of the Bush administration, and US President Barak Obama’s Hawaiian birth certificate is a forgery. Oh, and climate change is a hoax perpetrated by corrupt scientists who just want more government grant money.
