Why do some people want to find out about the world and others not? In reading about North Korea (nothing to envy) one of the stories was about an a high ranking individual who was able to obtain an officially sanctioned TV set. These sets are limited to only being able to receive one channel (official state media). The TV set can be randomly checked by state minders to ensure it stays that way. He fiddled with the set so it could receive South Korean TV and spent night after night crouched in front of it, the screen dim and sound barely audible. Why did he have to know? at such terrible risk?

The need to know the facts probably varies considerably between people.

I think first the person has to be able to enter a state of not knowing. This is an uncomfortable state and so (s)he is motivated to fix the discomfort by researching.

However, if the person cannot enter the state of not knowing then they will remain in the state of "knowing" everything (e.g. via religion)

The Dawkins' crushing argument approach is probably failing at this first step, though I don't know what the answer is.

Certainly the widespread availability of articles and books in the west means a person can go on a quest for knowledge (perhaps secretly) with little risk of being found out by their faith group. Its hard to see what more can be done.
