In a recent Radio Lab podcast on the subject of Choice , there was a segment on Harrahs Casino’s method of tracking and customizing the experience of it’s customers. Using a frequent players card, which players put into the slot machine while playing, they can track all the attributes of the players betting patterns and especially what your pain point is. With your losses at the slots mounting the casino knows when you are likely to get up and walk out of the casino. It is at this time that a casino employee drops by and gives you some comps (free show tickets etc) which makes you feel like you are winning and you are more likely to stay put, pulling the lever.

How much will you go down before you call it quits?
