It's back to Kahneman - we find truisms and easy answers to get us through large swaths of life, and then at some point we end up re-evaluating if this and that, and the answers can be quite surprising. Scientology calls it "stable data", some place to hang your hat, but quick & convenient solutions tend to wear out their welcome.

I give the example of the ostrich quite often - we probably don't think they really bury their heads as protection, and at 70km/h running, they're far faster than most of their predators. But we hear the expression early on and it's never explained in school (that they stick their heads into the ground to turn their eggs to keep from overheating), so we have a completely contrived wrong piece of info in our heads. In this case the info is useless and unused, and the analogy serves a bit of purpose anyway, so it doesn't matter. But we have so many false and detrimental "facts" that do over time distort our reality and decision making. When we blow off suspicious data, it's often a big relief (along with embarrassing and possibly disorienting), but it doesn't happen enough with rigor.
