Articles like this seem reasonable on their face, but in practice I really think what they come down to is "I have prejudices, I don't want to admit them, so I have all sorts of soft criteria like 'happiness' that allow me to exercise my prejudices with a good conscience." It's not necessarily simple racial prejudice, it's usually something more subtle around age or social class, etc.. It's a lot like "cultural fit", which often comes down to "something about this person made me uneasy and I don't want to quantify it". Compare this to Amazon's famous first job ad, which was just "we want top developers". Top devs are going to learn the tech skills that are needed. And hiring managers don't have the magical ability to peer into peoples' souls to determine what makes them happy.
