I'm not arguing that we should try to exaggerate our biases, or even to center them, but rather, we can become more honest by making our biases clear and explicit to those we're communicating with. Many organizations avoid openly addressing their biases, which makes them less honest overall, and more prone to being deceptive. If you're aware of your biases you can actually account for them, as opposed to letting them blind you. Further, if you're public with that awareness, others can account for them as well, and be less likely to be deceived (even accidentally) by your communication.
Too often, bias is ignored. It always exists. If we name it and make it visible, then we can have a chance at reducing its potential for deception.
