On regulating perceived risk

Area of Science:

• Risk assessment and management
• Public policy and regulation
• Science communication and media studies

Background:

• Societal reliance on government regulation for technological risk management has grown.
• Risk evaluation, once technical, is now politicized due to public controversy and media influence.
• The role of experts in risk assessment is increasingly questioned.

Purpose of the Study:

• To explore the nature of technical risks in aircraft, nuclear energy, and medicines.
• To analyze the impact of public controversy and media on regulatory decision-making.
• To examine the shift from minimizing actual harm to minimizing perceived harm in risk regulation.

Main Methods:

• Review of technical risks associated with aircraft, nuclear energy, and medicines.
• Case study analysis of media influence on public perception of risk.
• Examination of regulatory approaches and their effectiveness.

Main Results:

• Intensive regulation of aircraft has demonstrably improved safety records.
• Calls for regulation in medicines and nuclear energy are often driven by public controversy, with less clear evidence of safety improvements.
• Media plays a significant role in shaping public perception and influencing regulatory actions.

Conclusions:

• Public pressure, amplified by media, is a primary driver for regulatory intervention in risk management.
• Regulatory decision-making regarding risk has become more anecdotal and less systematic due to unpredictable public controversy.
• Regulators must prioritize minimizing perceived harm over actual harm, with a strong case for medicines due to lack of alternatives.
