In this case, can anyone explain how the old favourite: 'Extraordinary claims require extraordinary evidence' works here?
These people have made some extraordinary claims, but do I require extraordinary amounts of evidence, or just evidence that is extraordinary in a subjective manner (For example, going 'Wow!' when presented with it)?
Is the correct (yet not very sexy) phrase 'Extraordinary claims require ordinary amounts of extraordinary evidence'? When someone says a deer has appeared in my garden, and shows a photo of a deer, I regard that as sound evidence and accept it. Yet if someone says an Alien appeared in my garden and backs it up with a photo, I regard that as not enough evidence. Isn't it unscientific to demand more evidence in order to establish it as correct, simply because my mind cannot accept something like that?
