Nope. Nothing on uxmovement is ever backed up by any data, just vague assertions. The worst part is that they always frame their articles as "why X is true", but then the article is essentially "x is true because x is true".
Wish this was its own comment and was upvoted to the top. I stopped going to UXMovement after the author continually attacked visitors in the comments section that questioned his posts to the point of calling them assholes and idiots. He seems to just post his own assertions about what UX is without any valuable data points.
