Numbers have a magnetic effect on people and can anchor their behaviour. Behavioural specialist, Bri Williams discusses a golf study which found that professional golfers tended to take fewer strokes when the same hole was labelled as a par four compared to when it was labelled as a par five. The implications of this research extend beyond golf and into daily business life. It highlights how expectations are framed can significantly influence behaviour. Objective reality may be less important than the subjective perception of difficulty.
