The scientific literature pretending that gut feeling does not exist, is, in my own opinion, a legend. Most discoveries/invention were stumbled upon by collective efforts, a bit of intuition, lots of work, and a share of luck. Once something is found/made, then we clean up so as it can be shared and taught.

Scientists always had gut feelings, routinely shared and share their feelings, it's what makes most of discussion between scientists. It was always ok to have feelings. However, to build something somewhat reliable, feelings are not enough, so you do the work to turn a feeling into a falsifiable theory that ypu put to the test.
