Indoctrinating someone with the 'right' idea is as much of a trap, I think, as failing to think for yourself. We are all cosmic Schmucks (the S bit of TFYS), as Schmucks we often end up believing that we now what is right/best/most important... those are, however, assumptions based on some mix of knowledge, ignorance and subjective experience.
Encouraging people to think for themselves should be, IMO, independent of any attempt to teach them your personal beliefs of right, wrong, good or bad.
Mixing the two seems like a trap on both sides. The convincer is falling into a trap of believing they are right and should pass on the true knowledge... while the other schmuck is getting told what to believe within the trapping of being taught to think freely.
