Have you ever made a decision, only to find yourself second-guessing it moments later? Maybe you spoke up in a meeting and immediately wondered if you said the wrong thing, or left a social gathering feeling confident, only to replay your actions in your head and feel uncertain. For many of us, reflecting on our choices doesn’t always reassure — sometimes it fuels self-doubt.
As a cognitive scientist, I am fascinated by this gap between what people objectively know and how confident they feel. Indeed, your level of confidence can affect so many things – whether you speak up or act on your ideas, how much you study for an exam or stick with your decisions. And yet, the way confidence develops — or erodes — can vary dramatically between people.
