Sailor Kenshin said:"Scientists" like this change their minds with every new research handout.
It's called empiricism. Science is not dogma. It is not (or at least, it ought not be) a doctrinal faith fanatically adhered to and defended by wild-eyed zealots. In the course of rigorous investigation and testing, the truth will out. Those that stick to their guns in spite of countervailing evidence are the bad scientists, not the good ones.
