What's Scarier?

Lots happening over the weekend but I did, of course, make some time to watch TV and happened to catch A&E's top scary movie moments. I completely agreed with all of them (The Shining, Carrie, Texas Chainsaw Massacre) and then came the top 3.
Jaws and Alien were 1 and 2 while The Exorcist was number 3. There is probably something wrong with the list makers over there because there is NO WAY that Jaws is the scariest movie moment. No possible way.
That said, who gets to make those lists and where do I apply? I think I would do a great job in the list making arts.
