Behavior is strengthened by satisfying outcomes and weakened by annoying ones

Evidence

Thorndike sees here the makings of a bigger, more general law of nature. As he puts it, the results of our actions are either “satisfying” or “annoying.” When the result of an action is “satisfying,” we tend to do it more. When on the other hand the outcome is “annoying,” we’ll do it less. The more clear the connection between action and outcome, the stronger the resulting change. Thorndike calls this idea, perhaps the most famous and durable of his career, “the law of effect.” — Brian Christian, The Alignment Problem, 539
