Because DNA won't tell you whether the genetically-genius person smashed their head on a rock and is now totally unfit for your high-paying engineering job. No

Because DNA won't tell you whether the genetically-genius person smashed their head on a rock and is now totally unfit for your high-paying engineering job.
Nor will it tell you whether the genetically-average intelligence person spent 14 hours per day for the last 8 years in the code mines building awesome stuff.
I.e. it won't tell you the types of things that interviews are designed to suss out.
- londons_explore 2y agoAny test mixes signal with noise (Maybe that superstar candidate is just awful at interviews? Maybe the super lazy coder puts their laziness aside only for the interview day?) Combining many noisy factors into one, with the correct weighting, will always, on average, give better results than a single test. That means that as soon as DNA tests give even a weak prediction of 'iq' or 'leadership abilities', companies will integrate them into hiring processes if legal and cheap.
