Memories of dry cleaning, hot irons, etc.
Share this Content

I basically called myself OCD on the air today.  I copped to our guest, Christopher Pittenger of Yale, that I sometimes go upstairs five times to check and make sure the iron's off.  Maybe that's an exaggeration - it might be more like four.  Either way, our conversation about memory, and why we forget to do some things that aren't "automatic" was pretty interesting.  He's obviously concerned about curing serious mental illness and addiction.  

While this is important work, I'm personally really fascinated about what he calls the "dry cleaning effect" - why you don't remember to pick up your dry cleaning on the way home.  He suggests that we spend a lot of our day on "auto pilot" and that scares me....

I'm also kicking myself for not asking about another phenomenon - why is it that a group of 3 to 4 people, when given a question they all know the answer to, all "blank out" and forget at the same time.  I'm pretty sure there's a term for this...but I forget.
