# How Loss Aversion Creates Self-Defeating Moratoriums

The $2 billion problem hiding in your underwriting restrictions

Within 48 hours of a major wildfire, insurance carriers begin imposing moratoriums. Entire ZIP codes are shut down. Applications are frozen. The logic seems sound: we just experienced a loss event, so we should reduce exposure. But this instinct, driven by loss aversion, is one of the most expensive cognitive biases in the insurance industry.

Loss aversion, first described by Kahneman and Tversky in 1979, explains why the psychological pain of losing $100 is roughly twice as intense as the pleasure of gaining $100. In underwriting, this could manifest as an extreme overreaction to realized losses.

What if blanket ZIP code moratoriums were eliminating nearly half of profitable policies along with the risky ones? Industry analyses suggest that as many as 47% of addresses blocked by moratoriums may sit in moderate or lower risk areas according to granular geospatial data.

The behavioral mechanism is predictable. After a loss event, the 'availability' of that loss in decision-makers' minds makes future losses feel more probable than they statistically are. This combines with loss aversion to produce an oversized response: shut everything down in the affected region.

But wildfires don't follow ZIP code boundaries. A single ZIP code can contain addresses ranging from 'Very Low' to 'Extreme' risk. Consider ZIP code 91350 in Santa Clarita, where roughly 40% of the population lives in moderate-risk areas, areas that would be perfectly insurable but could be blocked by a blanket moratorium.

The financial cost could be staggering. Estimates suggest that overly broad moratoriums may cost the US P&C industry $2 billion annually in foregone premium, premium that could be written profitably with better risk selection tools.

What if carriers used address-level risk data instead of ZIP-code-level restrictions? They could replace the emotional, binary decision ('block everything') with a calibrated, granular one ('block the specific addresses above our risk threshold'). This approach could reduce wildfire losses by 30-40% while maintaining 60-70% of the premium that blanket moratoriums would destroy.

Loss aversion will always be part of human decision-making. The goal isn't to eliminate it. It's to build systems that route around it. When the data speaks at a granular level, the emotional impulse to 'shut everything down' loses its grip.

Your competitors are already using these insights to write better risks.

Don't fall behind.
