Prospect Theory

People evaluate outcomes as gains and losses from a reference point, feel losses more than gains, are risk-averse for gains and risk-seeking for losses, and overweight small probabilities and certainty.

An everyday example

Taking a sure $500 over a 50% chance of $1,100, but gambling on a 50% chance of losing $1,100 rather than accepting a sure $500 loss.

What it can cost you

Every one of these curves is a handle a seller can turn: set the reference point, frame the loss, promise certainty.

Warning signs

  • My risk appetite flipped when the framing flipped.
  • I did not choose the baseline I am comparing against.

One thing to do

Ask three questions of any offer: what is the reference point, who chose it, and what does the choice look like if I reframe it as its mirror?

Is this happening to you right now?
