        Another interesting line would be “how much I need to know to make a good decision”. People who understand the point of your chart often get decision paralysis, and always believe they need more info. But beyond a certain threshold more info increases confidence but not accuracy.

        Wait, so if the customer (client?) is the expert, why did they hire you as a designer? ...Or do you really mean customer as in somone using the app or site and making purchasing decisions?
