In response to the 1999 study involving the relationship of watching wrestling on television and engaging in date fighting, Vince McMahon issued the following statement:
 
"We regret that this seven year old junk science was re-issued. It was junk science then, and is junk science now. It took them seven years to get someone to actually read it and it hasn't even been subjected to a peer review. There is nothing new in the study, and we think it is recycled garbage put forward by some obscure professor who finally got someone to read his paper and is trying to get his name in the media."

Below is link to the 1999 study as well as an article from 2001 Media Life that quotes the head of Syracuse University's Center for the Study of Popular Television who debunks it.
