>It obviously takes more brain power to manage a company than it does to flip hamburgers.
Two problems with that.
1. Rich people pay others to manage their company, or, if they're rich enough, "manage" their company while paying or using their position to threaten other people into fixing or at least taking the blame for their constant fuckups, then they lie so much and with such conviction that they start living that lie; suddenly, they don't have to actually think anything through, if they have an idea they just demand that idea be realized and when it doesn't work or can't be fulfilled or creates more problems they just tell themselves it's not their fault and demand as well it be fixed.
For example: I had a boss once who would regularly spend more money bribing lawyers to avoid paying taxes than what it would've taken to just pay an accountant and the taxes properly. And he's not the worst, nor the richest, I've worked for or met.
But more often than not the richest will literally just pay someone else, often multiple people, to make all the important decisions while they are nothing more than a figurehead who also takes home the biggest check home (those are actually the smart ones, even if they'll act dumb when confronted).
2. people who flip burgers don't use their entire brainpower to do their burger flipping job. Like the taxes guy? He has literally no hobbies, no interests, and no topics of conversation besides whats most immediately relevant to the goings on of his business. Except for rich people gossip, what's needed for him to network for the promotion of his business. And even other rich people hate him because he has nothing to bring to a social interaction except promoting his business. Burger flipper guy might as least have 1 other thing going on in his life.
>People aren't going to be intelligence and then become stupid because they took a vacation for a year
No, but people are going to act stupider if they're, for example, nervous or anxious, if they haven't slept well, If something upsetting happened to them that morning, if they're ill or hungry, or not interested in the test, etc.
And sure, maybe you don't feel like these or any other number of things could affect IQ test scores significantly, but how could you know?
> it's the best test we have.
The best... but for what, exactly? For giving you a number with no real meaning that you can make fun graphs with, yeah. For actually telling how smart people are, specially to find trends in populations? nah.
Only one curious trend I find in IQ is that people who care a lot and claim to trust IQ tests more tend to be conservative older demographics, yet these same people also complain about how all young people are ignorant imbecilic retards for generally disagreeing with them on social and political issues or having different interests and skills. Yet the real trend in IQ is that younger people consistently score higher with each passing generation.
