Who is actually smarter - Paul who prefers stocks over ETFs and overthinks and overanalyzes everything and who is so confident that he thinks in the long term he can select the right stocks at the right time and sell them at the right time,
or Daniel, who knows that always selecting the right stocks in the long term is very hard even for high IQ people, so he prefers to just buy a world index fund.
Its often said that smarter people are bad at investing (Paul), but is Paul really the smarter one? After all, he fails to think further, he doesn't realize that his plan is pretty naive and that an EFT would probably be better for him in the long term.
