The process I follow for this was taken from an anthropologist criticizing his field's inability to reflect on their own perceptions and biases when "observing" other cultures. When you make observation involving a suspicious/strange/ironic/troubling/etc. element of a situation, the next step is to attempt an analysis of your known biases and influences. Try to identify how they affect the manner in which you express the observation. I think this area is the true value of conversation/discussion/debate. You then take your observation, on which you genuinely attempted a self reflection to purge biases and succeeded somewhat, and express it to those with differing perceptions to test the extent of validity. The end result should be between a focused and refined expression of an observation that is difficult to refute or yeah that is a peculiar coincidence.
