Neuroscientists call the brain an “anticipation machine” because it spends so much time predicting the future.[i] It does this by piecing together past experiences to build scenarios of expected outcomes, in a process that reinforces itself as predictions come true. But of course things don’t always come true, creating uncertainty and wreaking havoc on the anticipation machine. In mild cases this expresses itself in a sense of worry that things might go wrong.

Recent research has a lot to say about the anticipation machine’s relationship to the update impulse. Visions of the future don’t spring from a vacuum, but link to objects, expected outcomes, or something we think we want. This desiring process applies to just about everything, whether it’s a slice of pizza or the admiration of others. But here’s the fascinating part: Getting things is less powerful than wanting them.
