Intuition vs. data, experience vs. process, delay vs. risk. There are lots of opinions on whether (or not) to trust your gut. This author cites a number of studies and papers (including some of her own) that justify the concept that using your gut is not necessarily wrong.

She advocates taking into account the situation, what's available to you (time, data), as well as your experience. The more experience you have, the more likely you will have done or seen something in the past that is adding to your gut feel.

In the end, it's about intelligent decision making, and then making it work. It's not always the data.
