Thinking, Fast and Slow

by Daniel Kahneman

As you become skilled in a task, its demand for energy diminishes.

Studies of the brain have shown that the pattern of activity associated with an action changes as skill increases, with fewer brain regions involved.

Laziness is built deep into our nature.

Too much concern about how well one is doing in a task sometimes disrupts performance by loading short-term memory with pointless anxious thoughts

If you have recently seen or heard the word EAT, you are temporarily more likely to complete the word fragment SO_P as SOUP than as SOAP. The opposite would happen, of course, if you had just seen WASH. We call this a priming effect and say that the idea of EAT primes the idea of SOUP, and that WASH primes SOAP.
