Well, you might have different priors, leading to different posterior beliefs from the same data; or you might have different values, leading to different decisions or policy prescriptions from the same descriptive beliefs.

Note that I said someone who is more biased in an arena will disagree with me, not that someone who disagreed with me in an arena was exhibiting more bias.
