risk

You over-allocate resources to eliminate a minor, symbolic risk.

The zero-risk bias leads people to prefer the complete elimination of a small risk over a greater total reduction in risk elsewhere.

Research indicates that when presented with safety trade-offs, individuals choose options that reduce a negligible threat to zero. They ignore larger, more significant threats that remain partially unaddressed. You value the psychological comfort of 'zero' more than statistical safety.

Peace of mind often comes at the cost of actual security.
