Judgment and Decision Making
Prof. Bertram Malle
Fall 1995
1. Facts about relationships today
In light of the above facts, a decision-making perspective on current human relationships must address two main questions:
The answer to both questions is: by making more conscious choices. That is, we need to learn about out preferences and beliefs and about the mechanisms (evolutionary/genetic, social) that guide our behavior. This does not guarantee good outcomes, but we can make informed, responsible decisions that reflect more accurately what we really want.
3. Initial processes in mate selection
Assumptions, predictions, and studies within Buss' evolutionary framework.
Lykken & Tellegen (1993)
The four major antecedents of liking and attraction:
The choice of a long-term partner sometimes requires a decision not to
stay with someone. This is an understudied, underappreciated decision
that is very difficult to make for many people and therefore not
practiced well. Rather than seeing all break-ups as "mini divorces"
one could consider them as acts of preventing a divorce.
Sunk costs: The more people invest in something (emotionally, financially, temporally), the less willing they are to give up that investment-in order to save their reputation of being "consistent," because admitting a lost investment makes them feel foolish, because they always hope it will get better (which would then make the overall investment seem worth it...)
Social exchange: People decide to leave a relationship only if
their net rewards in that relationship are markedly lower than their
subjective standard ("comparison level") and if there is an
alternative. In early stages of relationships, alternatives are
easily conceivable and often available (e.g., other dating partners).
But with every further investment (living together, engagement,
marriage, children) alternatives are less likely to be available and
people therefore tolerate more discrepancies from their comparison
level. Breakups become increasingly difficult, and if they finally
happen, they are very painful and consequential for the partners and
often for children.
2. Conscious choices
In particular, how can we learn not to stay together with someone?Evolutionary influences on mate selection
Genetic influences on mate selection
Social influences on mate selection
4. Long-term partner choiceThe difficulty of breaking up
People often stay in bad relationships even though they recognize their own dissatisfaction. Why?
