2003? Yeah, a little out of date oogee. :)
I was looking for something more current but now I don't feel bad posting these.
Here are a couple of articles I found from 2009 about a study that Google spent 2 and a half years doing on errors in memory.

And, if you like whipped cream and a cherry on your DD, here is a copy of the Google study mentioned in the articles.
