I presented the paper on violence. Bear Braumoeller presented another one similarly critical of Pinker. After our session, the audience was split into:
1) Those who thought that Pinker was wrong
2) Those who thought that Pinker was not even wrong (i.e. not worth discussing).
And the agreement was to not talk about his thesis any further. Further, the organizer was told by Pinker that he did not wish to rebut our papers.
Pinker builds his thesis on works by Richardson in a way that is NOT compatible with the way Richardson [which is compatible with our result] and without showing the derivations. This it turned out is a CRITICAL flaw. Words and words and the central point is pulled out of nowhere.
In our paper: “As we also find out in our data analysis, consistent with Richardson (1960), there is no sufficient evidence to reject the null hypothesis of a homogenous Poisson process, which denies the presence of any trend in the belligerence of humanity. Nevertheless, Pinker refers to some yet-unspecified mathematical model that could also support such a decline in violence, what he calls a “nonstationary” process, even if data look the way they look.”
