Give players a safety net and they will play recklessly enough to need it -- safety features do not reduce risk, they redistribute it.
The Peltzman Effect, named after economist Sam Peltzman, describes how safety features lead to riskier behavior because people compensate for reduced risk by taking more chances. In gaming, it explains why auto-save makes players more reckless than manual-save systems, why respawn mechanics encourage suicidal rushes, and why shields and armor do not actually make players more conservative -- they make them more aggressive. The effect has profound implications for difficulty design: giving players safety features does not necessarily make the experience easier, because players unconsciously recalibrate their risk-taking to match the safety available.
Example
Borderlands players with strong shields play far more aggressively than players in games without regenerating health. Roguelikes without saves force careful play, while games with frequent checkpoints encourage 'YOLO' attempts. In competitive games, players with a life lead often play more aggressively (risking that lead) while players behind play more carefully -- the opposite of what rational strategy suggests.
Why it matters
The Peltzman Effect is a critical insight for difficulty design. It means that difficulty is not just about numbers -- it is about risk perception. A game can be mechanically easy but feel tense if there are no safety nets, or mechanically hard but feel relaxed if death carries no consequence. Understanding this helps designers create the exact emotional experience they intend.
