I use my intuition a lot and have learned to listen to it. Sometimes though, it sucks when you intuit something, turn out to be correct, and you don't really have a good explanation to your peers as to why you knew it was correct. I remember one time in my career, we knew we had a rogue server somewhere (out of probably 100k+) we had to decommission but no one in the org knew where it was and everyone that did had long been gone. All we knew was that it was out there in the stack somewhere, because we'd see the effects of its existence elsewhere in the metrics, but this thing was like a complete ghost. All we had to go on in the end was nginx logs that had hundreds of thousands of IP addresses in them, go through them one at a time with a script and run a certain curl to it, and hope we got lucky it was the one we wanted. Even then there was a ton of false positives.

I was skimming through it on a call and a certain address just popped out to me. I said "that's the one, I'm pretty sure I've seen that before." I had no real reason to believe this, I just had a very strong feeling that I recognized it from somewhere and felt like it was the right one. Sure enough it was. People on the call wanted to know how I knew, and I couldn't really describe it, it was just pure gut. That doesn't really translate well in a professional setting, people will think you're weird or withholding/hiding something.
