It can be reliably and reproducibly measured that diversity is more profitable. It’s as “always” as tylenol helps against headaches, trains for travel, google for searches, gravity for keeping you on the ground. Yes, there technically are times these don’t work, but it works more often than not, and typically there’s other factors when it doesn’t.
And similarly, yes you might not always pick the best candidate, but applying robustly provable best practices will lead you to doing it more often.
Do you go through anything else in life in this manner? That if you can’t do it perfectly, you’d rather not try? I’d wager not, as trying gets you closer to your goals, even when not meeting them immediately.


Then you’re lacking in imagination.
Similar data have outed people’s pregnancies, relationships and locations, which has been used to let people be stalked and even murdered.
Car data can be sold and amalgamated to create a very precise profile of you, available to be purchased by anyone. Anyone with about $100 can purchase access to your daily/weekly schedule, including physical locations, and can easily steal your identity, if not rob or murder you.
Also, foreign propaganda can similarly profile you and hyper target influence campaigns.
