Now Svetoslav Stoykov, the perpetrator of the crime, has been sentenced to 2 years and 11 months in jail after being convicted of causing grievous bodily in a German court (see here and here).
The perpetrator was reportedly a Roma Gypsy from Bulgaria, who was in Germany only because of the EU open borders policy, but this an issue for another post and time.
In his defence, it was claimed that Stoykov was under the influence of alcohol, marijuana, cocaine and crystal meth when he committed this attack.
But, importantly for our purposes, a psychiatric expert testified for him and claimed that Svetoslav Stoykov has an IQ of about 63 (see here).
An IQ of 63 is very low, and even 70 is considered border-line mentally retarded.
Presumably, Svetoslav Stoykov’s lawyers invoked his low IQ as a defence and as evidence that he was not fully responsible for his actions, and so therefore in support of the view that he deserved a more lenient sentence.
Now leftists and liberals quite often do invoke low IQ as a defence against law and order Conservatives who push for the death penalty for violent criminals.
But, at the same time, leftists and liberals have a schizophrenic hostility to the very idea of IQ as a meaningful concept, or as a reliable measure of the general intelligence of human beings.
But you can’t have it both ways.
(1) culturally-fair IQ tests are a meaningful and accurate measure of the human trait of general intelligence (also called Spearman’s g), which is also a meaningful and real phenomenon, orSo which is it? You can’t have it both ways.
(2) IQ is meaningless and does not constitute a meaningful measure of general intelligence, since the latter concept is also not a coherent, meaningful nor real phenomenon.
Either (1) is true and (2) false, or (2) is true and (1) is false.
If you think (2) is true, then you cannot invoke IQ as a defence for low-IQ criminals, because you actually think IQ is meaningless.
By contrast, if (1) is asserted as true, then you can in fact defend low IQ criminals as not being cognitively normal, and not necessarily having the same level of agency nor control as human beings with a higher IQ.
But, once you have acknowledged that IQ is meaningful and an accurate measure of the human trait of general intelligence, this opens up a whole world of issues that are normally ignored by the Left and Liberal Left, e.g., the issue of differences in the distribution of IQs of men and women, as described here.
