With those semantics people not only have a "gut feeling probability" but also a "heart feeling probability" and various similar "probabilities". Those don't have to be the same and depending on the context the person is going to use a different one.
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.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
