No there's a lot of articles on IQ and intelligence. Less on hard work. Mainly because most people on here are programmers and the job and interview is related to intelligence. People who take pride in there programming skill think they're intelligent.

As a programmer myself I think most programmers are average. Programming isn't a very hard job imo. It doesn't require a huge amount of intelligence hence the reason why it's one of the few occupations that can be entered without a degree, with self training, or a bootcamp.

People think this is a field that requires high intelligence. This is false. It's a field that requires slightly above average intelligence mostly. It depends on your specialty but for the typical web dev software engineer it's more closer to average.
