I was just wondering if anyone had any opinion on this article that came up in the New Scientist, especially the comments on hypnosis (quoted below) which came up near the end?

Another controversial forensic technique is hypnosis. Its reliability was tested experimentally in the 1980s by psychologist Jane Dywan of Brock University in Ontario, Canada, at a time when hypnosis was increasingly being used, with little opposition, to "refresh" eyewitness memory. She showed people pictures and then tested their recall over the following days. After a week, she hypnotised the same people and asked them again what they could remember. They all "recalled" more, but almost all the newly volunteered information was wrong.
Dywan says that hypnosis increases the focus of our attention and so increases the vividness and the ease with which information comes to mind. This may give us the sense of confident familiarity for false memories that we would normally only get with true ones. Hypnosis seems to interfere with our ability to judge what is real and what is not. Combine this confidence with increased recall, and you have set up a very dangerous situation, she says.
