I'm intrigued, do you have a source for that? It's a phenomenon I came across daily (say Covid) and because the world is becoming increasingly complex I would argue that so does the appeal of 'simple' explanations, or 'why the experts are wrong'.
I think the counterpoint to it is that it's also somewhat common for specialists to get stuck in local Maxima, as their expertise provide a deep but potentially narrow framework for thinking about the problem, and people with more broad experience may be more able to find more imaginative solutions.
There was a piece that I can probably dig up about the theory that this has quite seriously affected e.g. theoretical / particule physics - for decades we have spent more and more money trying to prove more and more complex versions of superstring theory etc., and what might be needed is more whacky out-of-the-box ideas that could lead to simpler explanations that fit our subatomic observations better.
