I disagree. We keep having disagreements on the "nature of man" brutish v. noble savages. Maybe there is no single type.<p>Maybe its our population that has two natures and a static percentage of us are brutish (37%) and short and the rest are noble (63% or vice versa). I think the nature of man has probably been ill-defined since it was conceived so long before statistics and psychology. Surveys and statistics are already attacking the concept of us as rational humans. Can't we just test for range of altruism v. jerkiness in the general population?<p>So I'm getting philosophical on Hacker News... whatever.
