Back when I was in junior high school (ca. age 13-14) I was in couple of "small enrichment classes" for social studies that engaged in a number of strategy/role-playing exercises. After a few go-rounds, they taught me to be deeply suspicious about buying in to the overt premises of such scenarios, because I discovered that not only were all the games deliberately corrupt (i.e., interactions that were presented as random and fair were actually being manipulated by the facilitator), but they were designed to lead you into acting unethically in order to teach "gotcha" lessons.

My newfound cynicism has carried over into adult life when presented with "team building" exercises that either teach entirely different lessons than the ones they purport to teach, or that simply reinforce my lack of team spirit.
