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.
Daniel LevitinYou'd think people would realize they're bad at multitasking and would quit. But a cognitive illusion sets in, fueled in part by a dopamine-adrenaline feedback loop, in which multitaskers think they are doing great.
Daniel LevitinThe most important, the longest lasting, the strongest emotional, and the most practiced memories are the ones that are embedded the deepest in the brain, and because we have retrieved them so many times previously, they are the most able to be retrieved. We all hear about people who can remember their youth, their phone number, or street address from 70 years ago, but they cannot recall what they had for breakfast. The memory of this morning's breakfast wasn't rehearsed, and wasn't very important, so it fades away quickly.
Daniel LevitinLove is about feeling that there is something bigger than just ourselves and our own worries and existence. Whether it is love of another person, of country, of God, of an idea, love is fundamentally an intense devotion to this notion that something is bigger than us. Love is ultimately larger than friendship, comfort, ceremony, knowledge, or joy. Indeed, as the Four Wise Ones once said, it may be all you need.
Daniel LevitinThe mammalian brain evolved exquisite place memory because that was essential for survival. This is why squirrels have such a good memory for where they buried their nuts.
Daniel LevitinThe brain has an attentional mode called the "mind wandering mode" that was only recently identified. This is when thoughts move seamlessly from one to another, often to unrelated thoughts, without you controlling where they go. This brain state acts as a neural reset button, allowing us to come back to our work with a refreshed perspective. Different people find they enter this mode in different ways: reading, a walk in nature, looking at art, meditating, and napping. A 15-minute nap can produce the equivalent of a 10-point boost in IQ.
