If scientists held a belief about our world religiously, would they necessarily recognize the fact? I have asserted my perception that belief in evolution is religious in nature (not scientific.) Obviously, this perception is itself not scientific. How would one go about conducting a controlled study? Still, I am open to the possibility that I may be wrong. I have even stated what would convince me. Show me a study (really, for a scientific theory there should be several) in which the evolutionary hypothesis predicts one outcome, previous observation together with the assumption that evolution is wrong predict a different outcome and that second outcome is agreed in advance that it will be recognized as a disconfirmer (a falsifier.) Conditions in which there is an "out" do not count. Evolution predicting a type of fossil cannot be used as there is always an excuse ready if no fossil is found. Declaring something a "potential falsifier" after it is confirmed not to occur (or would be considered highly unlikely to occur given previous observations) will not persuade me. For that matter, such things should not persuade scientists. Ordinarily, scientific theories go around with bullseyes on their backs. Evolution appears to have been coddled.
People have told me that their belief in evolution is not a matter of "faith." I have little doubt that they have convinced themselves. But their actions strongly resemble those produced by religious faith. They will tell me I need to do more research. It's very similar to the question posed by christians, "is it possible there is evidence for god in what you don't know?" It is quite impossible to exhaust all studies, and telling me to "do more research" seems more an effort to keep me busy and shut me up. When do I stop looking for the purple cow and simply conclude it is not there? I have not changed what will convince me. Yet people only point me to studies that fail the criteria. (One other failure that people cite as a potential falsifier is the proof of a universal negative, e.g. a persistent trait that provides a benefit only for a species other than the one in which it is found. These are not possible results because no observation could be proven to meet the condition.)
