I agree with everything except your last sentence. Much CAN be done to ensure those biases do not manifest in the results of their work. More generally, this is the power of our institutions.
Turtles would be so much simpler, tho. A tortoise will copulate with a boot for hours with no pretense about what he's doing or why. No justifications or excuses.
Us hairless apes on the other hand, we'll act contrary to all our good sense in the firm belief that "the job requires it" or "the boss wants it this way" or worst yet "the rule book specifies it thus". We can knowingly compound our stupidity and decry the results. Then expect praise for following the rules.
At least the tortoise gets the idea, at the bottom of the hole, "dig up, stupid!"
