"I don't understand what you mean here. If this is a commentdon my "exponential growth again" remark I find it strange. If you call that to be " incorrect about some underlying principles" I would say you are wrong, that is not an underlying principle at all, and everyone should be able to understand it cannot go on, yet a lot of people lose money every time."

Lets say I buy a stock that appears to be in a bubble situation. I believe that the stock will keep rising because the frenzy shows no signs of letting up. I am making some assumptions when I place my buy (e.g., the frenzy will continue, the economic situation hasnt changed, etc.). My assumptions may be wrong but it doesnt mean that I was irrational.

Maybe I can explain with another example. When I buy stock I assume the books arent cooked. Now, if it comes out that the books are cooked and the stock drops dramatically, it doesnt mean that I was irrational. It only means that my information is incorrect.
