The Mind is Flat: The Shocking Shallowness of Human Psychology

At the end of the first week I wrote that I found this course 'frustrating, infuriating, unconvincing'. I still felt that way at the end. Halfway through the course I gave up posting any comments because they were all negative.
The impression given was that we always think in the same way. We were not given the results of experiments, so we couldn't see how many subjects did NOT produce the majority reaction. There was no explanation given for these exceptions. Perhaps we can indeed think deeply, producing reasoned decisions based on good evidence, even though sometimes we may not bother.
It was a marketing trick to pretend that we ought to be able to sense things in absolute terms and then to show that we can't. There was a quick reference at the end of that section to why we are much better off using comparisons instead, but it seemed to be stuck in as an afterthought. There was some interesting stuff in the course, particularly when we got away from the flat mind, but it was difficult to find amid all the hype and the attempts to be sensational.

I found this course disappointing. I can accept the 'flat mind' idea, but as I see it, it implies that we are influenced by others much more than we think, and our trust may be misplaced. I was expecting illustrations of this, e.g. we trust banks even if they are gambling with our money, we tend to trust people similar to us leading to racism, sexism and so on. We are also very bad at putting forward persuasive arguments, relying instead on authority and emotional appeal.
The course didn't really deal with anything like this. Instead we were supposed to think it strange that not everyone has perfect pitch and that if house A is twice as big as house B then it will cost about twice as much. Then at the end we saw how people put a lot of mental effort into coordinating their behaviour with others, going against the idea of a flat mind.
