The problem with experiments has always been that human beings make the decisions on whether or not the animals have benefitted from the treatment.
James RandiScience is a search for basic truths about the Universe, a search which develops statements that appear to describe how the Universe works, but which are subject to correction, revision, adjustment, or even outright rejection, upon the presentation of better or conflicting evidence.
James RandiTo make sure that my blasphemy is thoroughly expressed, I hereby state my opinion that the notion of a god is a basic superstition, that there is no evidence for the existence of any god(s), that devils, demons, angels and saints are myths, that there is no life after death, heaven nor hell, that the Pope is a dangerous, bigoted, medieval dinosaur, and that the Holy Ghost is a comic-book character worthy of laughter and derision.
James RandiReligion is based upon blind faith supported by no evidence. Science is based upon confidence that results from evidence - and that confidence can be modified and/or reversed by further observations and experimentation. Science approaches truth, closer and closer, by hard dedicated work. Religion already has it all decided, and it's in the book. It's dogma, unchangeable, and unaffected by reality and whatever facts we come upon in the real world.
