Priming is a technique used in behavioral economics to influence the behavior of another person or group of people. It involves providing them with a stimulus that will activate a desired future response. For example, exposing someone to images of money will, in theory, make them more likely to behave selfishly afterwards.Unfortunately, this line of research has come under heavy scrutiny and does not seem to be valid. Chapter 4 of Daniel Kahneman’s book, Thinking Fast and Slow, covers priming and has largely been discredited.
