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.
How do you know this person isn’t at least somewhat well versed in the related fields? For all we know they have a double major?
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
