“If we can control the environment in which rapid cognition takes place, we can control rapid cognition.”
A hiring manager, though he loves his wife and daughter very much and wants the best for them, may not hire any women that come in for interviews because to him, women are weaker and more easily distracted. To him, his reasoning is perfectly sound; he is not aware of his bias. He listens with his eyes—he sees a woman and he immediately rejects her—instead of his ears and heart. He does not evaluate the woman on her skills and abilities, only on her gender.
Listen with your heart, not your eyes.
