Strategic Alternatives in Social Behaviour
Games like Hawk Dove and War of Attrition represent pure competition between individuals and have no attendant social element to the game. Where social influences apply there are four possible alternatives for strategic interaction that exist for the competitors. This is shown on the adjacent figure, where a plus sign represents a benefit and a minus sign represents a cost.
- In a Cooperative or Mutualistic relationship both “donor” and “recipient” are almost indistinguishable as both gain a benefit in the game by co-operating, i.e. the pair are in a game-wise situation where both can gain by executing a certain strategy, or alternatively both must act in concert because of some encompassing constraints that effectively puts them “ in the same boat together”.
- In an Altruistic relationship the donor, at a cost to himself provides a benefit to the recipient. In the general case the recipient will have a kin relationship to the donor and the donation is one-way. Behaviours where benefits are donated alternatively (in both directions) at a cost, are often called altruistic, but on analysis such “altruism” can be seen to arise from optimised “selfish” strategies
- Spite is essentially a “reversed” form of altruism where an ally is aided by damaging the ally’s competitor(s). The general case is that the ally is kin related and the benefit is an easier competitive environment for the ally.
- Selfishness is the base criteria of all strategic choice from a game theory perspective – strategies not aimed at self-survival and self-replication are not long for any game. Critically however, this situation is impacted by the fact that competition is taking place of multiple levels - i.e.at a genetic, an individual and a group level.
The rationale and the mathematics that lie behind adopting one of these alternative social strategies will be covered in the following sections of this article.

Famous quotes containing the words strategic, alternatives, social and/or behaviour:
“Marriage is like a war. There are moments of chivalry and gallantry that attend the victorious advances and strategic retreats, the birth or death of children, the momentary conquest of loneliness, the sacrifice that ennobles him who makes it. But mostly there are the long dull sieges, the waiting, the terror and boredom. Women understand this better than men; they are better able to survive attrition.”
—Helen Hayes (1900–1993)
“Clearly, society has a tremendous stake in insisting on a woman’s natural fitness for the career of mother: the alternatives are all too expensive.”
—Ann Oakley (b. 1944)
“A man is a beggar who only lives to the useful, and, however he may serve as a pin or rivet in the social machine, cannot be said to have arrived at self-possession.”
—Ralph Waldo Emerson (1803–1882)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
