Bias is an obstacle to judgement. Only those who aren't hungry are able to judge the quality of a meal.
Bias is something we should keep tabs on in ourselves. The more one is conscious of one's bias, the more chance one has of acting without sacrificing one's aesthetic and intellectual integrity.
Bias is difficult to see past. We rarely ever perceive others as being sensible, except for those who agree with us.
Bias is seeing things through a filter. If one's only tool is a hammer, everything starts to look like a nail.
Bias is inevitable — If a man can see both sides of a problem, you know that none of his money is tied up in it.
Bias is the cost we pay to experience the world. Though we think we can have our visions for nothing, even the finest and most self-sacrificing visions have to be paid for. Strangely enough, that is what makes them fine.
Bias is the reflection of ourself we place in our external world. We see things as we are, not as they are.
