During his recent visit to the office of 37 Signals, Jeff Bezos said, "to be consistently objective, one has to be objectively inconsistent." I find this perspective very refreshing that is applicable to all things and all disciplines in life beyond just product design. As a product designer you need to have a series of point of views (POV) that would be inconsistent when seen together but each POV at any given time will be consistently objective. This is what design thinking, especially prototyping is all about. It shifts a subjective conversation between people to an objective conversation about a design artifact.
As I have blogged before I see data scientists as design thinkers. Most data scientists that I know of have knowledge-curse. I would like them to be consistently objective by going through the journey of analyzing data without any pre-conceived bias. The knowledge-curse makes people commit more mistakes. It also makes them defend their POV instead of looking for new information and have courage to challenge and change it. I am a big fan of work of Daniel Kahneman. I would argue that prototyping helps deal with what Kahneman describers as "cognitive sophistication."
The problem with this introspective approach is that the driving forces behind biases—the root causes of our irrationality—are largely unconscious, which means they remain invisible to self-analysis and impermeable to intelligence.This very cognitive sophistication works against people who cannot self-analyze themselves and be critical to their own POV. Prototyping brings in objectivity and external validation to eliminate this unconscious-driven irrationality. It's fascinating what happens when you put prototypes in the hands of users. They interact with it in unanticipated ways. These discoveries are not feasible if you hold on to single POV and defend it.
Let it go. Let the prototype speak your design—your product POV—and not your unconscious.
