Humor is a great tool, especially among designers who have a tendency to take themselves too seriously at times. Dan Saffer, from Adaptive Path, demonstrated this in his talk on “How to Lie with Design Research” which you can view on his blog. Designers can have great intuition, making it hard sometimes to look at things objectively. This certainly happens at ID; you think you know exactly what’s going to happen, and what the research is going to show. Intuition is important and can help in beginning a project, but keeping an open mind to new insights from seeing what really happens is much more important.
