I was thinking about another problem with experts. Though it’s still worth it to trust them over your own intuition, in all too many fields (including medicine), at least 10% even if not intending to defraud you outright (that is another separate 10-20%) are just ridiculously wrong and might as well have bought their degree at some diploma mill for all the good it did them.

I don’t really understand why or how this happens, but it seems invariably true no matter the field.

Generally, I trust experts. But it always pays to get a second or third opinion as you never know when you’ll get an “expert.”
