From “8 Rare Gems from Heidi Roizen on Building a Fulfilling Life and Career” (I highly recommend the full article):
3. Your gut has more information than you do.
Increasingly, tech culture is about the opposite — making decisions driven by exhaustive data. “There’s this idea that the more data you have, the better the decision you can make. That may be true for some things, but not everything,” says Roizen. “Gut instincts are built on years of experience and subconsciously what you observe about human nature from every interaction. They are informed in ways we don’t even understand.”
A wise friend and oft-time advisor of mine once told me: “Your gut is taking in all the input from the external world and constantly computing that into an interpretation or a decision for you, so trust it.” As much as I read about cognitive biases (and I believe they are real), I have found my gut to be surprisingly keen through my own experiences and mistakes.
Yes, there is no scientific theory in favor of the gut. But then, there was no theory why hot water often froze faster than cold water, which had been an observed phenomenon for decades and only recently explained scientifically.
