At the end of the day, people always make decisions based on emotion, because every decision involves assessing risk, including the risk of things that were not thought of testing. Data only tells you about the past while decisions only affect your future.
There's a difference between making a decision based on emotion, and making a decision based on wisdom and data. Frequently, when I have a hard decision to make, I wait a while until I'm feeling "less emotional", so that my normal knee-jerk reactions don't dominate.
