We all have a bias. I do and so do you. How conscious you are of it and what we do to mitigate it it, is another thing. Tall, short, fat, thin, glasses, bald, hairy, tattoos, blonde, brunette, ginger, shoes, dress, suit, piercings, accent and more and more types of bias are entirely legal. But all they do is limit your ability to hire talent because they get in the way of finding out if the person in front of you has the skills and competency for the job as opposed to triggering a decision based on conscious or unconscious bias.
