Availability, Affect, and Decisions to Seek Information about Cancer Risks.

Area of Science:

• Psychology
• Risk Perception
• Health Communication

Background:

• Individuals often lack comprehensive information about various health risks.
• Decisions about which risks to learn more about are influenced by cognitive processes.
• The availability and affect heuristics are known to shape risk perception.

Purpose of the Study:

• To investigate the role of availability and affect heuristics in selecting cancer information.
• To understand how personal networks and emotional responses influence information-seeking behavior.
• To examine the interplay between heuristics, judged risk, and information choice.

Main Methods:

• Participants (N=100) chose which cancer information brochures they wanted.
• Assessed cancer occurrences in social circles (availability heuristic).
• Measured emotional dread towards each cancer type (affect heuristic) and judged cancer prevalence.

Main Results:

• Participants preferred information on cancers more frequent in their social network (availability).
• Information choices were also driven by the level of dread associated with specific cancers (affect).
• Judged risk partially mediated, but did not fully explain, the influence of availability and affect on information selection.

Conclusions:

• Availability and affect heuristics significantly guide decisions about seeking health information.
• These heuristics operate in information choice, extending beyond risk perception.
• Findings can inform strategies to ensure critical health information reaches relevant audiences and prevent risks from being ignored.
