News and Memory

Easier to Recall
Frequency Substitution
People estimate frequency by the ease with which examples come to mind.
Distortion
Media prominence and personal experience can replace actual statistics.
Disaster Cycles

Memory of Catastrophe
Immediate Vigilance
After earthquakes or floods, victims buy insurance and prepare intensely.
Fading Concern
As memory weakens, protection declines and complacency returns.
Availability Cascade

Fear Becomes News
Reinforcing Coverage
A minor event attracts concern, which attracts more reporting and still more concern.
Policy Distortion
The issue grows politically urgent while quieter risks disappear.
Love Canal and Alar

Public Scares
Dramatic Symbols
The Love Canal affair and Alar scare turn fear into national environmental action.
Ambiguous Legacy
The responses may have protected people, yet also redirected resources inefficiently.
Terrorist Salience

The Image of Danger
Tiny Probabilities
Repeated images make terrorism feel more urgent than common traffic deaths.
Emotional Policy
A rational policy must address both actual danger and debilitating fear.
