Emotion and decision making

Emotion and decision making

  • Case: Phineas Gage

  • Experiment 1:

    • A group of people, some normal and some suffering from prefrontal deficiency was

    • Exposed to a fire alarm

    • Shown value laden pictures

  • Experiment 2:

    • Choice of card decks

Rationality f llesdal 1992

RationalityFøllesdal 1992

  • Four dimensions of rationality

    • rationality as logical consistency

      • pertains both to values and beliefs

    • rationality as well-foundedness of beliefs

      • beliefs are well supported by available evidence

    • rationality of action

      • application of decision theory

    • rationality as well-foundedness of values

      • reflective equilibrium that gives a stable set of convictions that are relevant for the decision situation

Fred Wenstøp


The rational decision model

The rational decision model

  • Frame

    • A set of mutually exclusive decision alternatives has been identified

    • A set of relevant objectives has been identified by which to evaluate the alternatives

  • Well-founded scores (x) have been established

    • Predicted consequences of the altenatives, beliefs

  • Well-founded weights (w) have been established

    • Importance of the objectives, represent values

  • Decision Table

    • Contains all the information above

Fred Wenstøp


Rational choice

Rational choice

  • An evaluating function that is in accordance with the decision maker’s preferences has been identified

    • U(x1,x2,..) = f(w1,w2,…,x1,x2,..)

  • The alternative with the highest expected value is chosen

Fred Wenstøp


Common evaluating functions

Common evaluating functions

  • Linear model

    • U(x1,x2,x3) = w1u1(x1) + w2u2(x2) + w3u3(x3)

  • Multiplicative model

    • U(x1,x2,x3) = w1u1(x1) + w2u2(x2) + w3u3(x3) +

      kw1u1(x1)w2u2(x2) + kw1u1(x1)w3u3(x3) + kw2u2(x2)w3u3(x3)

      + k2w1u1(x1)w2u2(x2)w3u3(x3)

  • These models ensures consistency of preference

    • Assumptions

      • Value and preference independence

  • The Panel

    • Governmental advisor on AIDS matters

      • Svein-Erik Ekeid

    • Deputy minister, Ministry of Social Affairs

      • Emil Hansen

    • Director of National Institute of Public Health

      • Bodolf Hareide

  • Decision context

    • Identification of viable program target groups

  • Value focusing

    • Essential values were identified without discussing consequences of alternatives

HIV Case: Weights

  • Weight elicitation

Hiv case conclusion

HIV Case: Conclusion

  • The viability study showed that

    • in order to be efficient, any program directed against an immigrant group must prevent new HIV cases at least:

      • Europeans665

      • Americans & orientals510

      • Sub-Sahara Africans100

  • A simulation study showed that

    • if left to themselves they would at the maximum infect

      • Europeans 20

      • Americans & orientals266

      • Sub-Sahara Africans376
