  1. Evolution of Risk Mechanisms Stimulus-Response action Emotional System Rational System

  2. Stimulus-Response action

  3. Emotional System • Fear - Mechanism for avoiding predators. • Anger - Mechanism for combating rivals. • Disgust - Mechanism for avoiding disease. Mechanisms for avoiding danger in the African Savannah.

  4. Rational System

  5. Dual Systems / Process theories • Emotional system • Heart / gut feelings • Evolutionarily old • Rational System • Head / logical thought • Evolutionarily young, • probably arising with language

  6. Risks have changed • Human bodies, adapted to the African Savannah, now live in very different places. • In the modern world technological advances have changed the landscape of risk. • We rely on our rational system to protect us from these modern risks, which are evolving faster than our emotional system has evolved to deal with them.

  7. Modern Risk

  8. Voluntary - Involuntary

  9. Natural - Man Made

  10. Single Large Scale – Numerous Small Scale

  11. Reversible – Irreversible

  12. Chronic – Catastrophic

  13. Processing information about risk • Systematic Processing • Detailed understanding • Slower • Relatively stable and persistent attitude towards topic • Heuristic Processing • Superficial understanding • Faster • Attitude towards topic may change • Efficiency at the cost of sometimes drawing the wrong conclusions

  14. Heuristics and Cognitive Biases • Availability heuristic • Representativeness heuristic • Affect heuristic • Loss Aversion • Confirmation bias • Negative bias

  15. The role of the media, advertisers and other companies. • Journalists “Seek Truth and Report It” but they also have to sell newspapers to keep their jobs. • They implicitly exploit our evolutionary worries and interests e.g. more bad news than good. • They attempt to present a balanced argument which can distort non 50/50 arguments • What is the motivation of the person selling the idea?

  16. Advertisers do the same Selling things by association and emotion, not logic and rationality.

  17. Food Manufacturers Food labels that provoke an emotional response are more likely to stop us buying a product than labels that provoke a rational response.

  18. Summary of Main Points • We evolved to deal with risks that no longer present us much danger. • We have 2 main mechanisms for dealing with modern risk (the Dual Process theories): Emotional and Rational systems. • These mechanisms shape our interests and where we pay attention. • Media and advertisers sell us news and products that feed these interests.
