One example heavy in my mind is El Reno. I broke away from the storm before the wedge came down, as I just had a strong gut feeling that it was too much for my experience level and the traffic and proximity to the city freaked me out. I still wonder what would have transpired for me if I had not listened to that voice.
That's a good example for discussion. I feel that you indeed made a logical (and a good!) decision based on specific evidence. You weren't so much going off your gut, but reasoning why you felt uncomfortable with your situation by recognizing the dangers present with the state of the storm, the traffic, and proximity to urban areas.
While in my original post I was thinking more along the lines of forecast decisions, I feel that a number of chasers may be putting themselves in danger by relying on their guts when making maneuvering and safety decisions underneath supercells. It seems to be a habit of many (myself included) that when they sense danger they immediately act on some default exit path. This is usually toward clear air, or simply south. It's a knee jerk decision. It's a gut decision. The two step thought process usually goes something like, "Danger! Way out!" There's little consideration for the way out. In the case of El Reno, dozens of chasers were racing the tornado across its path or driving straight into the tornado, mainly because they were acting on a knee jerk escape route. Stopping to think and using a little reasoning could have saved many from vehicle damage and injuries. Pausing to use some reasoning, the thought process would go something like: "I'm in danger! I'm northeast of the tornado. The tornado is moving east. While there is clear air to the south, heading north would take me directly away from the tornado."
There are times during the chase when gut decisions are great. Moments that rely on creativity and artistic expression and not logic and reasoning, such as framing a photograph, are moments when you're using specific reasoning, but also relying heavily on your emotions, subconscious, and other miscellaneous influences.
The forecast is a scientific process. There's no voodoo involved. If it seems that there is, it's because the atmosphere is overly complex and we don't have all the variables. It's usually possible to make a forecast decision from the few variables we do have a grasp on, however. Underneath the storm, making a decision that your safety depends on based only on emotions or reflex is almost as dangerous as panicking.
