Two friends, Colin and Rose are arrested for shoplifting together. They each hire lawyers to represent them, and each is separately interviewed by the police.

Colin and Rose are told the following:

· Because Colin has a prior record, and because a witness saw him shoplift one item, even if neither Rose nor Colin “tells all”, Colin’s sure to get at least a sentence of 3 months. In all likelihood, Rose would go free in that case, as she has no “priors”.

· If Colin gives a full confession (including Rose’s involvement) before Rose does, he will be given probation for his cooperation. In that case, Rose will get 6 months in prison.

· If it should happen that these interviews end with both Colin and Rose confessing, then Colin will get 6 months, while Rose (due to her clean record) will get 3 months.

· If Rose “tells all” before Colin does (including agreeing to testify to Colin’s involvement), she will go free on probation, while Colin will get 9 months in prison.

Get into groups of two.

1. Decide how Rose is likely to rank the four possible outcomes. (1=worst, 4=best). Then decide how Colin is likely to rank the four possible outcomes. Combine these rankings into a 2x2 matrix as we saw Monday.

2. One of you pretend to be Rose while another is Colin. Simultaneously choose which strategy you would choose to follow (confessing everything or staying silent). Record the outcome you end up with, and how you each ranked that outcome. Repeat this 5-10 times, adjusting your strategy as you see fit.
