Overconfidence is a powerful cognitive bias, this is why it happens and how you can avoid it. Research into overconfidence implicates it in impairing judgements across a range of situations including investors’ over-trading behaviour, managers’ poor forecasting, their tendency to introduce risky products, and their tendency to engage in value-destroying mergers. Overconfidence is one of the most powerful cognitive biases because it is so ubiquitous, and causes us to make important judgements and decisions without a sensible degree of consideration. Fortunately, there are some strategies you can use to reduce overconfidence.

Music can make a huge difference in your workday. Feel free to crank up the volume if noise has you working like a snail, you’ve got a case of the Monday’s, or you’ve got something mundane or familiar to do.

Lastly, if you have something to learn, pump up your mood with music before you get started.
