Smart people can end up with retarded opinions and incorrect priors, but generally speaking, one of the most critical talents that you need as a solo indie game developer is the ability to learn new things very quickly, since there is a shit ton of skills that you'll need to learn, and there's not enough time in your lifespan if you learn too slowly. How quickly you can learn a topic is most directly measured with IQ.

You'd be surprised. The barrier to entry is quite low. There also appears to be a bimodal distribution of developers who have gotten to the point of downloading an engine and trying. There are the <115IQ midwit "kenyan helicopter flopdev NGMIggers" who don't have the level of introspection necessarily to figure out they're producing worthless garbage, and thus can remain delusional enough to persist in their fruitless endeavor. In the 115-145 range or so, you'll be smart enough to figure out what a truly monumental task creating an good game that people actually want to play is. This is the range where many neverdevs rot away in. It's not really until the 145+ range where you're really able to filter out all the noise and follow a realistic path to success.
