Bias, Asabiyah, and Oman's Three Monkeys

The recent Human Trafficking Report labeling Oman as an unchanged Tier-3 country has caused some back-and-forth on Oman's blogs. There are links to the right under "Interesting Posts." Interestingly, an unrelated blogger, EmiratesEconomist recently posted a quote from the Overcoming Bias blog (which I can't get to open for some reason): "being more aware of biases makes us more willing to assume that others' biases, and not ours, are responsible for our disagreement."

So, while highly educated people should be more aware of biases, they could just as easily turn that knowledge about biases around to assume that the other person's bias is the root of disagreement. I think this works both ways in the recent debate. And how would Ibn Khaldun's concept of "asabiyah" or in-group solidarity play into this quote about biases?
