In reply to EZ:
Interesting that whilst an argument completely unrelated to the Internet Forums thread is raging on that thread... nobody is up for arguing this one! It surprises me (to a point). Maybe it's a bit too close to home? Maybe it's not a valid debate?
So it seems that by default Daily Mail is out and New Scientist is in? Peer reviewed studies shall not be questioned (let alone the peer review process) but personal experience shall not be admitted because there is no 'evidence' to back it up?
Maybe it is just not possible for the people who debate other topics to view the subject objectively?
Recommended reading: Manufacturing Consent - Noam Chomsky and Ed Herman. Admittedly it is written from a quote unquote leftist position though that discounted it still gives a good format for appreciating some of the criteria for assessing the validity of sources.
