The scientific method is useful, but highly overrated. The scientific method is a powerful tool, but it is a general technique that simply does not function, or does not function well in many, perhaps most real life situations. Many trivial questions like “is this person (my child, my spouse, my government representative, that policeman) lying to me?” or “are their motives good?” as well as very complex questions like “do gods exist?”.
It is of no use when complexity is too high to make a scientific analysis, and if pushed in such situations, produces authoritative garbage. It is of little use when a timely decision is required. One of our strengths as humans is out ability to make good decisions, even, at times, based on bad data. Sometimes we can successfully make good quick decisions based on wrong assumptions and bad data data, by using our cognitive biases with good intentions.
