You make better remote associations when:
A. You are tired.
B. You have had a drink.
This sounds crazy, but apparently, there has actually been research done on this.
I enjoyed this infographic on beer vs. coffee.
But what do I know?
(Interesting fact: we get better at solving insight problems when we are tired or intoxicated. Why? Our executive function is inhibited, so information that would normally be deemed distracting is allowed to filter in. We thus become better at seeing remote associations.
