Peltzman Effect – when feeling safe makes you take more risks

Electric editorial collage illustrating Peltzman Effect

Do you act more recklessly when you feel safe, even though the risk remains? That’s Peltzman Effect – the tendency to offset increased safety by engaging in riskier behavior.

Where it can show up


- Driving – people drive more aggressively in cars with advanced safety features than in older models.
- Sports & outdoor activities – skiers or cyclists go faster when wearing protective gear, assuming it will save them.
- Finance – investors take bigger risks when they believe their losses are insured.

A practical countermeasure


- Safety doesn’t make you invincible – protection reduces risk but doesn’t eliminate it.
- Monitor your behavior – don’t let a sense of security lead to reckless decisions.
- Think about consequences – if you’re taking bigger risks because of added safety, ask yourself if it’s really worth it.
