Yes, and it is not science.Strawman. Sorry. Your understanding of human behaviour is facile. The purpose of orthoganal explanation is to avoid this. There is not stronger form of argument, please don't pretend to lecture.
On the data, you're argument is from Ignorace. The author of that book is one of the most knowledgeable people on the planet on that subject. Like it or not, your opinion has not been substantiated by any form of counter argument.
I don't need "objective" argument when I have intersubjective authority. You're argument about "science" is laughable in its in-applicability and ultimate irrelevance.
Which is obvious as well from your trivial citation of correlation/causation.
You don't understand how to create an argument and verify it using empirical data. The practicum on this is evidenced by the techniques of Special Forces operatives and all kinds of actual professional killers. These people don't have the inclination, the incentive, or the bandwidth to develop techniques which are failures.
The fact that you think Academics hold a superior position to actual killers on the subject points to the double weakness in your argument: (1) Academics have no actual experience; and (2) academics have all kinds of conflicted incentives to lie, the least of which is there pre-held political beliefes and naive understanding of actual human nature.
Try again. Or actually, don't. Actually, just read that book. The link to this discussion was not the motivation or the functional purpose of that series of working papers. The latter just became obvious and self/evident later (much of the background material, for example pre-dates the mid-1980s).[1]

[1] Edit: As an aside, where do you think Andres Breivek got his idea to prepare for the massacre on Utoya? You should do some research on that as well. Both before and after there is relavent data on the record about it. The data there are also in distinct contradiction to your "argument" here.
