I remember the moment I unlocked the critical thinking I do have.<p>It was 7th grade, and I was in a home-ec-like class. The day before we had learned how to order from mail order catalogues (showing my age there). This day the teacher passed out magazines, told us to pick an ad, and then find 5 ways it was misleading.<p>Easy, right? Sex, money, Fame, these associations are in a bunch of ads, and everyone knows about them. But it turns out that 5 is a pretty high number for some ads. You had to really look. And even that didn't change anything for me.<p>Then we presented to others. And one girl showed an ad for Bayer, and said "4 out of 5 doctors recommend. Who picked the 5 doctors?".<p>My mind was blown. I think it was the moment where I considered myself a good judge and then was shown a point I had never even considered. I had thought all about having careful wording on the survey, not mentioning any negative results, but I had never considered that the very basis of it could be manipulated to the point of meaninglessness.<p>I think that moment of fundamental distrust, in both what I'm being told, as well as in my own certainty, did the trick.<p>Perhaps too well - I'm hypersensitive to being manipulated. I rejected any career that involved deliberate group manipulation, such as military, law enforcement, and legal. I recognize that EVERYTHING is manipulative to some degree and can't be avoided, but I try to avoid anything that does it very explicitly, so I can't for example, watch most documentaries. The moment the vocal pacing and background music starts something in my brains starts shouting "YOU ARE BEING MANIPULATED!" and I try to fight that manipulation, which is largely impossible so I generally end up turning it off. Ditto political speeches (I'll skim the transcripts, thanks), most anything out of marketing, etc.<p>I don't really think we can "teach" critical thinking, but we can provide opportunity for it again and again. I think our school system in the US (no experience elsewhere) is very poorly set up to do that, be it college or pre-college.
