Well it's not an exact parallel. The scientific method is definitely more accurate than history. The fact that historical records can be tampered with notwithstanding, there's also the numerous factors of any given scenario which one must take into account. What happens when alcohol is prohibited? We can see what happens when it's prohibited in the United States during a certain era but that does not mean prohibiting alcohol will produce the same affect each and every time. Conversely, in the realm of science combining two chemicals together will always produce the same effect. Legalizing marijuana, for example, may work in some countries and not in others. Unfortunately, it's just not as cut and dry as the scientific method. Cultural and geographical factors will play a large part in what works in one place and not in another. The new implementation of a certain law may be wildly successful in one region of the globe and yet result in disastrous consequences in another. It's not as simple as carbon dioxide + water = glucose + oxygen.
