1 – Reciprocity is an evolutionary necessity for any species that is capable of voluntary cooperation.

2 – The test of reciprocity is prior investment (cost/expenditure)

3 – Reciprocity is decidable independent of preference.

4 – Local allocations of decidability over property (investments) evolved to preserve reciprocity and prevent retaliation cycles.

5 – The principle determinants of property allocations are marriage and inheritance structures, which in turn are dependent upon agrarian, pastoral demands, and hunter gatherer phases.

6 – The six moral intuitions can be divided into defense of private investment, and defense of commons.

7 – Male and Female brain structures and reproductive strategies, and moral biases vary (predictably), producing the demonstrated distributions that exist everywhere.
