Meh. Not really. There is a strong connotation in American English for "gut feeling" that means essentially instinct or intuition.
Here's a definition I found via Google's first page results: "an instinct or intuition; an immediate or basic feeling or reaction without a logical rationale"
This is what I meant. I think that would be clear to a high percentage of readers.
Here's again the problem that you don't look at the way humans reason but against the abstract concepts defined in the dictionary.
The way terms are defined in the dictionary has little to do with the empiric reality that some people give different intuitive answers when they feel into their gut or when they feel into their heart.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
