Social exchange theories exist in various forms but the underlying theme is that people may be selfish.
Social exchange theories argue people may view relationships in a “profit” or “loss” way.
Thibaut & Kelley believed people will look to see how rewarding a relationship is and then how much it costs to be in the relationship. If there is a profit left over (rewards – costs = profit) then that may encourage them to continue the relationship where as if there is a loss – this may motivate them to end the relationship.
Blau argued that interactions are “expensive”, as they take time, energy and commitment and may involve unpleasant emotions and experiences. Therefore what we get out of a relationship must exceed what goes in.
Walster et al believed that social interactions involve an exchange of rewards, like affection, information, status. The degree of attraction or liking reflects how people evaluate the rewards they receive in relative to those given.
SET is therefore an economic theory explaining relationships in terms of maximising benefits and minimising costs. The “Social exchange” is the mutual exchange of rewards between partners; like friendship, sex and the costs of being in the relationship may be freedoms given up, time, effort.
A person may make their assessment of their rewards by using two comparisons:
The comparison level (CL) – where rewards are compared to costs to judge profits. This may be based on past experiences and relationships as well as what we expect to get from a relationship.
The comparison level for alternative relationships (CLalt) – Where rewards and costs are compared against perceived alternative relationships and how they compare.
A relationship is maintained if profit is perceived in both these two comparisons.
Thibaut & Kelley proposed a four-stage model setting how relationships could be maintained, predicting that over time people develop a predictable and mutually
