An extreme example of not listening to instinct
I clearly remember Captain Oddenes saying that going north at this time of the year is quite contrary to what his sailor experience would have recommended. But since the routing agency had all sorts of satellites and computers to help them to predict the weather, – Captain Oddenes decided to take their advice and go north, instead of following his own instincts and years of experience! – from The Storm in context of going straight through a hurricane. Complete with 22+ meter waves. There are a bunch of other great pictures there too.
The moral of the story? Have faith in your instincts; especially when you have trained them appropriately. The main difference between a new tester and one that has been doing it for 10 years is that they have had time to train their intuition. To think like a tester.
