As are its failures, but you would rather these weren't mentioned as they undermine your reliance on it. As for answering SKoS's question, I've explained in a number of places across this board, and then briefly explained again in my last post. It's all about 'testing' or asking questions.
errm what are these failures exactly?
People make an observation.
They develop an hypothesis of what the principle factors might be.
They then test the hypothesis against previously untested data (in a way that is independent of the person carrying out the test and in which the variable(s) under scrutiny have been isolated.
If it fits, the hypothesis is accepted (on a provisional basis).
If the model doesn't match reality then the model is refined of rejected.
If the model matches reality then it becomes our best understanding until further data comes along that refines or destroys the model.
What is wrong with that approach?
Can you outline a similar method for you on-naturalist stuff? i.e. following on form the previous thread can you give me the name and adrees of an academic who has published a paper that says that scientific explanations to spontaneous healing CAN be ruled out.
I did a search of Elsevier and ScienceDirect the other day (as part of my professional subscription) but failed to find one.
