All good points listed in the comments. My view is that most of these depend on the ability and practice of thinking for oneself. I once pondered if/when I had a clearly original thought that wasn't connected or influenced by something closely related. It was surprisingly difficult to come up with strong concrete examples. I did come up with a good one though--back in grade 7 long before the Tau manifesto I came to the conclusion that Pi was dumb: why make a ratio vs a diameter that's made up of 2 R's? It was an epiphany at the time (so was able to remember the actual moment in time and place when we were being shown constructing the area by adding the two semidiscs sliced in wedge ribbons). Clearly a ratio of full arc vs 1 R is more 'pure' in a sense. The fact that so many people can't even imagine Pi being so awesome and perfect today despite the Tau manifesto shows how clearly influenced they are and incapable of thinking differently from the masses (at least on this point).
