We believe that the schools must serve as the principal medium for developing in youth the attitudes and skills of social, political and cultural criticism. No. That is not emphatic enough. Try this: in the early 1960’s, an interviewer was trying to get Ernest Hemingway to identify the characteristics required for a person to be a ‘great writer’. As the interviewer offered a list of various possibilities, Hemmingway disparaged each in sequence. Finally, frustrated, the interviewer asked, ‘Isn’t then any one essential ingredient that you can identify?’ Hemingway replied, ‘Yes, there is. In order to be a great writer a person must have a built-in, shockproof crap detector.’
It seems to us that, in his response, Hemingway identified an essential survival strategy and the essential function of the schools in today’s world. One way of looking at the history of the human group is that it has been a continuing struggle against the veneration of ‘crap’. Our intellectual history is a chronicle of the anguish and suffering of men who tried to help their contemporaries see that some part of their fondest beliefs were misconceptions, faulty assumptions, superstitions and even outright lies. The mileposts along the road of our intellectual development signal those points at which some person developed a new perspective, a new meaning, or a new metaphor. We have in mind a new education that would set out to cultivate just such people – experts at ‘crap detecting’.
We are talking about the schools cultivating in the young that most ‘subversive’ intellectual instrument – the anthropological perspective. This perspective allows one to be part of his own culture and, at the same time, to be out of it. One views the activities of his own group as would an anthropologist, observing its tribal rivals its fears, its conceits, its ethnocentrism. In this way, one is able to recognize when reality begins to drift too far away from the grasp of the tribe.

Through their training, scientists are equipped with what Sagan calls a “baloney detection kit” – a set of cognitive tools and techniques that fortify the mind against penetration by falsehoods:
> The kit is brought out as a matter of course whenever new ideas are offered for consideration. If the new idea survives examination by the tools in our kit, we grant it warm, although tentative, acceptance. If you’re so inclined, if you don’t want to buy baloney even when it’s reassuring to do so, there are precautions that can be taken; there’s a tried-and-true, consumer-tested method.
But the kit, Sagan argues, isn’t merely a tool of science – rather, it contains invaluable tools of healthy skepticism that apply just as elegantly, and just as necessarily, to everyday life. By adopting the kit, we can all shield ourselves against clueless guile and deliberate manipulation. Sagan shares nine of these tools:

Like many a science communicator after him, Sagan was very much concerned with the influence of superstitious religious beliefs. He also foresaw a time in the near future much like our own. Elsewhere in The Demon-Haunted World, Sagan writes of “America in my children’s or grandchildren’s time…. when awesome technological powers are in the hands of a very few.” The loss of control over media and education renders people “unable to distinguish between what feels good and what’s true.”
