In fact the above is so prevalent that I'm specifically admiring leaders who are exceptions, actually take responsibility and care more about their workers, clients and the many other people they impact as opposed to their individual gains via compensation and social currency at the top (board, shareholders etc.)
Also CEOs generally work hard regardless of the quality of their work. But they generally have a ton of responsibilities and people to talk to. In terms of time invested per day, it is not uncommon for them to do several hours more work than say an engineer.
(It's not the same _kind_ of hard though, I personally find social activities, reading and communication much less exhausting than technical work, but it's also less fun.)
CEOs have specific education and/or experience to help them make better decisions. They suck just as much as anyone else at unknowns.
> the CEO will probably do better at flipping burgers than the average employee
this is the same old magical thinking "CEO's are special people" bullshit
The following study shows this connection for low skilled job. It also shows that the connection has to do with IQ correlating with better understanding of the role, so wont show until after the worker has learned it, but the connection is still there so you'd expect the CEO to learn the role better than an average employee.
> As others have pointed out, statistical corrections are no magical compensation for weak data and that it is risky to reach conclusions about test validities from those currently available (Oswald & McCloy, 2003; Russell & Gilliland, 1995). The only solution is properly conducted primary studies, with larger representative samples, better measures, and so on.
Here's the important bit that basically advises not using IQ tests in the exact way that you're using them:
> Until they are available, investigators should be extremely cautious about disseminating conclusions about IQ test validities, from correlations between IQ and job performance.
CEO is a job title, not a measure of intelligence, or even job performance. There are no shortage of shitty CEOs, just as there are no shortage of shitty performers in just about every possible job.
