From the article it felt like nobody had called BS because they didn't understand the math at all, not because they were afraid of their careers or something. It is extremely rare that a researcher tries to debunk an article because they realise they don't understand differential mathematics.

This is actually almost a bigger problem! Being scared of debunking others can be somewhat easily corrected if there's enough will, but if the bulk of psychology researchers don't understand enough mathematics to design unbiased studies and interpret data, the results are random at best.
