Action Bias – when taking action feels better than doing nothing

Do you feel the need to take action, even when waiting would be smarter? That’s Action Bias – the tendency to act in any situation, even when inaction would be more effective.
Where it can show up
- Sports – goalkeepers dive during penalties, even though statistics show staying put is often better.
- Finance – traders make moves just to ‘do something,’ even when the market calls for patience.
- Management – leaders introduce new processes and changes, even when things are working fine.
A practical countermeasure
- Ask if the action adds real value – sometimes the best move is no move at all.
- Don’t act just for the sake of action – impulsive decisions often do more harm than good.
- Remember that inaction is a strategy too – sometimes waiting and observing is the smartest choice.
