What credentials does this author have to cite social science research in their determination of the competency of other people? Their only other article is about eschewing native apps - why am I supposed to take their opinion about measuring competency seriously if they are a software engineer, not a psychologist? They are clearly outside of their domain of expertise and therefore incapable of producing work with any value whatsoever, according to their own arguments.
oh, believe me, I can just tell from the way they're talking about stuff, just like a webapp/psychology double major is well-versed in evaluating data systems
