Highly excellent series of posts. However, is there not a need to take account of more/better data on the aspects of human psychology that these Ethical Injunctions are there to protect against? Eliezer derived the hypotheses from evolutionary theory, but is not more solid empirical data needed in order to more accurately determine how severe these psychological effects are and in turn to more accurately design good Ethical Injunctions? Or will good Injunctions likely be so general that such a level of accuracy is not necessary?
