I too was surprised. My gut reaction is this is "my guy" syndrome where people are still reasoning in the third person even though the problem says "you" - if you were to mad-scientist this experiment I bet you'd have a near 100% self-preservation response.

On the other hand, some of the responses have a small contingent disagreeing, and to explain those I would remind you of the Lizardman Constant [1]. That is, some pollsters just want to watch the statistics burn.
