The guy is a hack.
As it turns out, Kanazawa is a repeat offender, with years of roundly criticized and heartily debunked pseudoscience-based shock-jockery under his belt. Despite this, he is still posting on the blog of a reputable mainstream publication, still teaching at a respected university and still serving on the editorial board of one of his disciplines peer-reviewed research journals. Though, possibly not for long: this particular posts racist hypothesis offended many, unleashing serious righteous outrage across the internet: social media users raced to blog, tweet and even petition demanding that Psychology Today remove Kanazawa as a contributor to their Web site and magazine. Psychology Today removed the post late Sunday night, and Monday morning the largest student organization in London (representing 120,000 students) unanimously called for Kanazawas dismissal.

I have it on good authority that “satoshi kanazawa” is Japanese for “bull sh!t.”
