To try and get a handle on what may be the most important scientific theory to arise in the 21st century, I thought I would go to an expert. Dr. Henry L. Roediger is one of the foremost experts on false memories in North America, so I wrote him about the Berensteinites to get his thoughts. His response made it clear he believes what's happening is more Occam's Razor than X-Files.
"I'm not sure that misremembering one letter in a long name is a major league false memory," he wrote VICE in an email. "My guess is that in this case that "stein" is remembered because it is a common ending of many names—Einstein, Frankenstein, Goldstein, etc."
