One of the things that contribute to this effect is, if you’ve believed something to be false for a long time, your culture is going to have lots of plans and extrinsic values that it drew up on the basis of that, but if you just found out about this thing, you’re still going to have most of those plans, and you’re going to say “well look at these (extrinsic) values we still need to satisfy, this wont change our actions, we are still going to do exactly the same things as before, so it doesn’t matter”
Only once you start going back and questioning why it is you have those values and whether they still make sense, in light of the new observation, only then will you start to see that your actions need to change. Since there isn’t a straight connection between habit/action and beliefs in humans, that update still might not happen.
