I literally had an econ professor years ago who directly told us “do not take a genetics test”. This was before the ACA
The reason was simple. It’s information that once a private company gets a hold of it, they will use it to hurt you. Whether it’s a drug company that learns you’re predisposed to addiction, so better to give you it people around you nice temporary discounts on addictive meds, or an insurance company that learns you’re predisposed to cancer, so better to look for ways to deny or drop coverage.
Once these companies know a little bit about your nature, they’ll exploit any aspect possible to increase profits.
This was not a progressive/socialist econ professor. Just someone who knows how capitalism works.
You’re probably affected by this even if you didn’t participate.
The thing about genetics is you can make reasonable predictions about individuals if you have data on their relatives. Heck, you can reasonably make regional predictions with genetic data that will be fairly accurate.
If any of your parents, grandparents, aunts, uncles, cousins, siblings, etc took this test, then you are now at least a little exposed.
