Life stages and risk-avoidance: status- and context-sensitivity in precaution systems.

Human typical life history involves specific tradeoffs, resulting in the selection of specific cognitive adaptations, among which a suite of age- and gender-specific precaution systems sensitive to variations in the physical and social environment. Precaution systems take into account the individual's status and life-stage, information about specific threats, as well as the fact that the organism can or cannot address those threats unassisted. Systematic variation in individual decision-making and behavior in risky situations provide insights into the operation of those precaution systems. The literature survey is completed by data gathered among the pastoral Turkana of Kenya showing how variations in precautions and risk avoidance correlate with age, sex, and social conditions.
