gambler’s fallacy | believing that a coin toss is more likely to come up heads if the previous five flips were tails |
anchoring | the tendency to rely heavily on one piece of information—usually the first thing we learn—when making a decision |
the Ikea effect | disproportionately valuing things that you’ve labored over |
unit bias | assuming that a “portion” is the right size, which accounts for our tendency to finish off an opened bag of cookies |
