Pseudocertainty Effect – when you avoid risk in gains but chase it in losses

Do you prefer a guaranteed win but take risks to avoid losses? That’s Pseudocertainty Effect – the tendency to be cautious when things are good but take risks when things go bad.
Where it can show up
- Investments – you sell profitable assets too soon to ‘lock in gains’ but hold onto losing ones, hoping to recover.
- Health – you choose safe treatment when the prognosis is good but take risks when things get worse.
- Business – you opt for steady profits over new opportunities but take big risks to save a failing project.
A practical countermeasure
- Assess risks the same way in all situations – don’t fall into the trap of being cautious in success but reckless in failure.
- Don’t chase losses – if you’re already losing, making an emotional bet won’t fix it.
- Focus on long-term outcomes – don’t let fear or short-term thinking drive your decisions.
