Decision-making is difficult because, by its nature, it involves uncertainty. If there was no uncertainty, decisions would be easy! The uncertainty exists because we don't know the future, we don't know if the decision we make will lead to the best possible outcome. Cognitive science has taught us that relying on our gut or intuition often leads to bad decisions, particularly in cases where statistical information is available. Our guts and our brains didn't evolve to deal with probabilistic thinking.

I have never seen a proton or electron spinning around it. I have never actually seen a chromosome. I trust that they exist because people who I trust tell me they do.

We really are living in an age of information overload. Google estimates that there are 300 exabytes (300 followed by 18 zeros) of human-made information in the world today. Only four years ago there were just 30 exabytes. We've created more information in the past few years than in all of human history before us.

The constant nagging in your mind of undone things pulls you out of the present--tethers you to a mind-set of the future so that you're never fully in the moment and enjoying what's now.

When a language advances and adds a third term to its lexicon for color, the third term is always red.

People are trying to build a society where they can talk across the aisle so to speak, and have civil discourse. At the same time we're trying to inform ourselves about what's really true so that we can make evidence based decisions that is better than superstition or rumor. But the fact is that people who use evidence based decision making have much better life outcomes, greater life satisfaction, they live longer, they make better personal and medical decisions, better financial decisions. But parallel to that is you can't reason somebody out of a position they didn't reason themselves into.

Although I don't know Paul McCartney, a mutual friend told me that Paul was reading my book, This Is Your Brain on Music, and stopped after chapter two. McCartney said he was concerned that if he learned more about how he does what he does (as far as composing music), he may not be able to do it anymore!
