"But on the other hand, does it really make sense for everyone to do their own diligence in every matter?"

It probably depends on what is at stake. I don't particularly care about superconductors, but I do care about my knees, and when one doctor several years ago wanted to operate me, I sought a second opinion elsewhere. Sure enough, the other clinic told me that this can be treated conservatively.

I canceled the operation and, 6 years later, I have zero problems, zero pain and can walk just fine, even up/downstairs. I am not sure what the operation would do; knees are sensitive joints and don't like to be cut open.
