There’s a nice little experiment undertaken by
Christopher Chabris and
Daniel Simons at Harvard University in which subjects were asked to count
the number of times a basketball was passed back and forth in a short
video.
Half of the subjects tested were
so absorbed in their assigned task that they did not even notice a person in a
gorilla suit walking into the middle of the action, thumping its chest, and
leaving.
This experience of missing what
is right before your eyes because you are focused on something else has come to
be known as inattentional blindness.
How does a person snap out of inattentional blindness? You don’t need an argument to show you that a
gorilla was in the scene, you just need someone to point it out to you. Both the demonstration of your inattentional
blindness and the “cure,” as it were, is a simple re-orientation of
perspective. Maybe you will need to
watch the video again, or maybe the simple prompt, “Did you see the gorilla?”
will be enough to make the missed phenomenon snap into place.
I want to suggest that there are forms of collective
inattentional blindness, which are harder to discern and even harder to snap
out of, but that a socially-engaged practice of phenomenology can help us with
both. My example will be – not
surprisingly for those who have read any of my previous blog posts – the
invisibility of mass incarceration in the US.
Every chance I get, I remind people that the US incarcerates
more people than any other country in the world. It can get pretty annoying, actually, both
for me and for them. But it’s a point
that still seems to float, like a gorilla pounding its chest, into the middle
of each and every scene of everyday life in the US, without being noticed.
Look at this image, for example. It’s a planner’s sketch for proposed
developments in a part of Nashville that they are trying to get people to call
“SoBro.” (You can click on the image to see more of the details.)

What would it take to see this sketch as a scene of mass
incarceration?
