Yes, it’s true… anecdotal evidence sometimes turns out to be untrue. However, it’s also true that science-based evidence sometimes turns out to be untrue. Thus, whenever you hear someone argue that something is true because it is based on science, rather than anecdotes, remain suspect… at least until you have studied the information yourself and the manner in which it was gathered and analyzed. Remember, science is a process, a methodology. It is only as reliable as those conducting it and the purity of the system under which it is undertaken. If the conductors are idiots or compromised or of weak character, then so will the science likely be. If the system is impure and corrupt, then so will the science likely be. In short, do not always disregard anecdotal evidence and do not always assume science-based evidence is valid. Exercise your brain.
