Sounds like a textbook example of restriction of range.
If you hire based on, say, STEM expertise, all of your employees will have lots of it. If you then do a study on what explains performance differences among your employees, STEM expertise will look useless, whether it is or not, because your employees all have similar levels of it.
The only real lesson you can draw from that is "don't do studies that have no theoretical chance of revealing any information".
Following your link, I notice that the top two replies are both making the same point.
