Yes, that's (overly reductively stated) the point of TFA. Except for the part where it was highlighting a survey result to the contrary, and explaining why this is irrational and doesn't likely reflect what people would actually do.

The idea behind claiming you'd choose the blue button is to appear noble and altruistic, I suppose; but I struggle to even understand that instinct. Risking one's own life to possibly save the lives of others who are demonstrably completely capable of saving themselves doesn't strike me as particularly noble.
