The ‘sour-grape effect’ Let’s first examine the sour-grape effect , discovered by Hallgeir Sjåstad, a professor of psychology and leadership at the Norwegian School of Economics, and colleagues. He says he was intrigued by people’s tendency to abandon their dreams prematurely. “The research was an attempt to understand why we sometimes give up too early, even though we could have succeeded if we had been a bit more patient and willing to give it a second try,” he says.

They were asked to estimate how much 20 apples would weigh, for example – and they were told that a guess falling within 10% of the real answer would be considered a sign of strong intuition. High performance on several questions, they were told, correlated strongly to “positive outcomes in life, such as extraordinary achievements in work and a well-functioning social ...

Alternatively, we may simply fail to notice our errors and blithely continue as if nothing has happened, something that prevents us from learning a better strategy to improve our performance in the future.
