MIT Visiting Professor Dan Ariely's Door Game demonstrates people's tendency to not let go of options.

The book Predictably Irrational (HarperCollins, 2008) by MIT Visiting Professor of Behavioral Economics Dan Ariely explores how people repeatedly and predictably make the wrong decisions in many aspects of their lives. For example, Ariely’s research shows that people have difficulty dropping options, even if they clearly waste time or money. Don’t believe it? Play the doors game and find out how you fare.

Ariely’s book answers questions such as why people excitedly buy things they don’t really need, why self promises to diet and exercise are so often in vain, and why a headache may vanish after taking a 50-cent but not a five-cent aspirin. His Web site offers numerous games, videos, and demonstrations that explore and expose everyday, irrational behaviors. Check them out and see how irrational you are.
