Be Open
Avoid coming to the table with preconceived assumptions about the user, the problem, the solution you want to build, or what the majority of users are doing or thinking. Instead, consider that opportunities could be present in the minority of users that could offer important insights for new products or features (for example, if 25% of users are unhappy with the common check-out experience, how can it be improved upon?). Be open to being proven wrong during the research stage.
