The weekend before Thanksgiving, we spent a morning exploring the Exploratorium. We especially enjoyed the Science of Sharing exhibit.

Briana and Helen check out the Prisoner’s Dilemma. They got it right for the one-off: both defected. What happened when it got real?

Rules of engagement and payoff matrix: You can give your partner a drink or a squirt:

Helen and Briana decided to give it a try. Helen chooses; notice that Briana has already made her choice.

What did they choose? Helen goes for a drink; Briana doesn’t even bother….

And… Helen gets a squirt! Look at that smirk on Briana’s face. And, she would have gotten a drink. What will this do to lab morale?
