Here is a test to decide whether you are biased or neutral: Do you have a phone? Yes. Use text messaging? Yes.
Are your messages filled with phenomenal energy for your best friend and zero interest for someone you admire a little less?
If yes, then you are biased.
By no means I am asking you to love your enemies and friends equally, yet there is something in your aura, some effect that you radiate, a joy that is unique only to you, a grace that belongs only to you.
When you use that aura, you raise it higher. When it gets higher the power is discernment automatically gets better.
