If rationality is about accomplishing your goals, then it takes many forms, including intuition and habits. We are not trying to copy Spock. We are trying to make good sense of the world, and to make good decisions to achieve our goals.
The reason is that we operate under deeply unscientific environments like partial-information, uncertainty and unpredictability.
On the contrary, we developed tool of thoughts for working in environments of vast uncertainty. Consider the battlefield, for example, commanders must make decisions in the fog of war. They are certainly interested in trying to make the winning decisions to achieve their strategic or tactical goals.
Technically you can try to be always rational in your life and play the 'risk minimization' game, but you will probably have a very mediocre life with limited success.
If a mediocre life isn't what you're looking for, then it isn't very rational to make choices that result in a boring life.
