Wisdom in diagnosis, then, involves not only deep knowledge about human biology and an understanding of the array of diseases that plague humankind but also knowledge and understanding about how the mind works in coming to conclusions. Discerning when these biases are operating in our minds is called metacognition, the ability to think about our thinking. The attribute of humility is embodied in the concept of metacognition; we recognize that our minds are imperfect, that there are limits to the validity of our assumptions, that we are subject to biases, and that therefore we must have the sharp sense to doubt our judgments and question whether we considered everything that should have been considered.

Designers and marketers (not to mention politicos and entertainers) have become adept at manipulating these biases in consumers and users, but I wonder how many are aware of how their own biases may affect the design process itself — or simply the question of which problem to solve…
Here is the book the launched the “heuristics & biases” paradigm and here is a list of cognitive biases that have probably influenced things you’re working on right now.
