Eh, the more I think about it though the more I can think of times that "Going by my gut" when my brain and gut disagreed where my gut was wrong.

Like suppose you're talking to somebody over text and your gut says they're being an asshole, but your brain is rereading what they say and can't find anything specific to call out.

Which is correct?

Well, I've found that the gut is systematically unreliable in a number of situations... Are you in a bad mood for example? They say never go food shopping when you're hungry.

Not to say mind > gut, because that's just as stupid as saying gut > mind. The point is that there are dozens of variables (variables like mood) we need to learn in such evaluations, and generalizations can rarely be useful.
