Analytical design and human factors

Please elaborate on the differences between your analytical information presentation principles and the human factors design approach. I thought the latter was to present information in a way that was within the human capabilities to perceive and process. If true, wouldn’t that design imperative completment the content drives and cognative needs which you stress underlie your univeral principles. But I understood you to say your approach and human factors’ were opposites in an answer at UCLA. Thank you.
