All behaviour is a result of people trying to maximise rewards and minimise costs
We enter relationships with the expectation of 'earning a profit'
We maintain relationships if they are profitable but will not be maintained if costs outweigh the benefits
What are Comparison Levels?
A standard, based on social norms and our previousrelationships, by which the the current relationship is judged
A relationship will be maintained if the potential profitexceeds our comparison level
What are Comparison Levels for Alternatives?
We compare our current relationship with to any potential alternatives - including being single
We weigh up the potential increase in rewards from an alternative partner (or being single) against any costs associated with ending the current relationship
We end the current relationship if an alternative could have a better outcome
Limitation of SET - The 'economic' metaphor is incorrect:
Clark and Mills - Identified two types of relationships
Exchange relationships (e.g. work colleagues) - Do involve an expectation of profit
Communal relationships (e.g. romance) - Involve giving and receiving without keeping score
Limitation of SET - Not a complete explanation:
Miller
Showed Ps photos of attractive people
The Ps in committedlong term relationships spent less time looking at the picture
This suggests we don't weigh up costs and benefits, or consider alternatives, unless we are already dissatisfied with the relationship
Comparison is a symptom of unhappiness
Limitation of SET - Culture Bias:
Moghaddam argues that SET only applies to relationships in individualistic cultures
In individualistic cultures it is about what profit YOU get whereas in collectivist cultures they value everyone involved
Limitation of SET - Equity Theory:
Relationships aren't just about you and the profit you can get out of a relationship they are about being fair for both partners
