Barnum Effect
Have we all been fooled by type tables? We organize people by categories and ask them to talk about their experience and then point out how this proves type? Isn't this a kind of circus act in which we create an expectation and then reinforce it without really testing it? How can we "tease" out what is real in these kinds of activities?

This is very timely, Roger. I have been thinking about the Barnum Effect and type quite recently, as well as related concerns about confirmation bias. I too have concerns about the lack of controls in how we validate type.
