In the case of SSC I really worry that NYT would be trying to exercise control. They probably like many things written on the blog, but also hate other things like diving into statistics of gender based pay discrimination or statistics of racial motivation in police violence.
These are topics which the modern left (which I’m a million percent a part of) is increasingly pushing out of scope of the Overton window and treating them like they are not allowed to be subject to statistical evidence or neutral discussion.
There is only One Right Thing To Believe about police violence (that is targets blacks and minorities, even if this is simply not supported by data). There is only One Right Thing To Believe about gender-based pay discrimination (the popular notion of “women make 70 cents on the dollar” which is not close to the real effect size, and requires a ton of uncomfortable nuance to discuss properly because of confounding effects of women staying at home more often and choosing to stay home after maternity leave).
I think they want SSC to write about things that comply with their moral narrative, and see doxxing as a way to turn the screws and essentially promote a vague threat that if he writes something controversial about IQ or sexism or income inequality or whatever, and it doesn’t stick to liberal talking points, they can do a damaging hit piece.
