Friday the Thirteenth

20438510.jpgI’m not particularly superstitious, so this day doesn’t cause me undue angst. Nevertheless, I still find myself thinking about it due to the general chatter in the media, at the office water cooler, and so forth. And despite my disbelief, it’s still hard not to think about it, at least momentarily, if something goes wrong. I find that I have to mentally reaffirm that I think it’s just coincidental. That’s my personal mental model.

Now, a University of Oregon study indicates that people on average can retain only four items in active memory at once. Whatever the number, the clarity with which items can be remembered varies from person to person. And even the people who can remember more items do not necessarily remember them more precisely.

Now I have a new reason to forget about this day. If I have to remember that it’s Friday the thirteenth does it follow that I can only keep three other items in my memory? Being that’s it’s hard enough to remember things as it is, this adds fuel to my mental-model fire if you will.
