I agree with Christopher that rapid cognition is “real and useful”, but is not in and of itself gospel and should be “taken with a grain of salt.” It is finding that right grain of salt that is the most challenging. Christopher further points out that “rapid cognition can be useful given the right preparation” but then he discusses the question of bias.
I believe that bias cannot be avoided, but if it is understood and you understand how it is coloring your perceptions, you are less likely to fall into the trap as experienced in the Bronx shooting of Amadou Diallo. While it is politically incorrect to even discuss, we must investigate precisely what the biases are, how they are created, and then seek for ways to eradicate them. I am speaking about negative stereotypical biases, but there is a fine line in our perceptions between archetype and stereotypes.
I also work as an IT worker and so I also use rapid cognition for “quickly analyzing a situation and suggesting a profitable direction of inquiry” I believe this must be due to the volume of unorganized data that is presented for my attention, so in a sense, my mind is organizing it through previous experience of what has been profitable or not. I agree that in my scholarly field, I also am hoping that as I read more and work in the field, my thin slicing and rapid cognition will become more profitable.
On the reference to the research by Ekman and Tomkins, I never thought about how the research must have been. Seven years is a long time, I must have overlooked this in my reading. I do agree that a lot of our internal state is shown by our faces unintentionally.
