Natal Aspects & Murder - a new study
Posted: Sat Mar 12, 2022 3:02 pm
In the early 1950s, Garth Allen (Donald A. Bradley) published a statistical study of the nativities of 42 murderers. Though the sample size was small, this study unlocked many important general principles and has been a basis of considerable interpretive practice in the intervening 70 years.
I recently noticed that my compilation of murderer horoscopes numbered 71 - two-thirds more than Allen's study. This is still a modest number, but seemed worth breaking down for a comparison. It has the weakness (perhaps shared with Allen's original study) that the examples aren't from a consistent source - they're literally what I had on hand and was able to grab over the years.
Garth Allen didn't detail his procedures, but I'm pretty sure (from some half-obscure statements) that he was using an early version of the angularity curve and aspects curves he worked on (on and off) through his life, probably through a special chi-square way of calculating that Gary Duncan showed him. Eventually (perhaps somewhere around TMSA 1.1 <g>) we'll be able to do the same sort of thing but, for now, I've worked out methods that give comparable results: Since aggregate statistical significance of aspects drops off just after 3°, we get much the same results by straight tabulations (head counts) of Class 1 aspects. I've found it useful to tabulate trines and sextiles separate from the hard aspects and then add them in for comparative results (I know Allen used all five in his tabulations). For this particular study, in order to better emulate the effect of a graduated curve, I had the inspiration this morning to add an extra point if the aspect is partile.
I'll show these in three stages. First, though, a review of what was found in Garth Allen's original study: Overwhelmingly, Venus-Mars aspects overwhelmed everything else. (They were so numerous and prominent that he had to show the results as a broken bar; otherwise, it would have flowed off the right edge of his bar chart.) The other highly distinctive aspects were Moon-Saturn, Sun-Mars, Sun-Neptune, Mercury-Neptune, Mars-Neptune (and Venus-Jupiter looks longer than most). There was a distinct shortage of Moon-Venus aspects (different from the charts I have in the present set), Mercury-Jupiter, and Sun-Pluto. We won't necessarily copy these results (since we have different data), but it's good to know what was found before.
I have added Eris and Sedna aspects, which have something to teach us here.
