Most theories would argue that a good model needs testing. How do you test your Persona's? Testing means that you need to measure the output of your model, and compare it to the real world. I really do not see how you can do this with Personas. How can I be certain that the model has no confirmation bias in it? > This is simply an example of a bad persona set How do you know if it is a bad persona set? What test can I do see if it is a good one, or a bad one? John von Neumann said, 'with four parameters I can fit an elephant and with five I can make him wiggle his trunk.'"

It may help the conversation if you try to building a Persona from the example originally given by Jared.
