What is the term Sam used to describe the phenomenon when you have expertise in a niche subject and see how misinformed everyone is?

Sam described a phenomenon where when you have expertise in a certain domain it's glaringly obvious how misinformed the media and public is, but then on other topics you forget and start to trust that everyone knows what they're talking about.

I know someone else asked this recently but I was trying to find the term and my google fu isn't bearing fruit.
