I didn't mention Brexit, I was talking about the election that made this Wylie character famous. Nevertheless, again, despite the claims in random Twitter posts here and there, mountains of evidence point to psychographic profiling being largely ineffective regardless of what type of vote it is being used on. “Swinging the vote by a few percent” is a major undertaking. It is not “trivially easy to do,” as you put it, certainly not through scientifically dubious methods that (in the case of the 2016 election) are not even actually used. Mr. Wylie is a programmer that violated confidentiality agreements with his employer to try to gain notoriety and presumably raise his income. That will make him difficult to employ ever again in any traditional setting, even among those that are sympathetic to his political beliefs. He seems to believe, or at least wants others to believe, that he is today’s Edward Snowden - even though the two couldn’t be more different. I don’t know how well his monetization efforts are working out, but based on the fact that he is now making clickbait-type public statements that can be easily debunked to get media coverage, it seems that it may not have worked out as he planned.
