Then who is the skepticism going to be mainly applied to?

I recently posted in Critical Thinking - Much talk and little action, that there was a gap between how widely we praise critical thinking and how little we do as a society to cultivate and encourage critical thinking.

Carl Sagan in Wonder and Skepticism has an explanation.

If skeptical habits of thought are widely distributed and prized, then who is the skepticism going to be mainly applied to? To those in power. Those in power, therefore, do not have a vested interest in everybody being able to ask searching questions.
