Yes and no. You can sometimes take a decent guess at an author's inner motivations by looking at repeated themes. Heinlein was notoriously fixated on sexuality, and increasingly on child sex and incest as the years went on. MiaHM is apparently one of the tamer reads, though I have basically given up on him after reading three of his novels.

Another classic trope of his is the "hyper-competent" man, who is incredibly self-assured, is smarter and can do everything better than the average person. Hard to say exactly what drives this, but my guess is it's either a superiority (I'm better than these fools) or inferiority (I wish I was better than these people) complex.

I agree, for some authors it can be hard not guess at their state of mind after reading several of their books.

The hyper competent man trope is fairly ubiquitous, maybe part of what drives this one is pandering to the target audience.

It’s also pretty convenient in a story - the protagonist (if said hyper competent) doesn’t hit roadblocks they can’t overcome eventually, regardless of what they run across.

And who wouldn’t want to be hyper competent in everything?
