Do You Know the Razors?Read Now
In this post we are going to go over the several razors available for us to use. These razors, while commonly used by philosophers and scientists, in fact are often used by regular people, sometimes without even knowing that they are using them! However, these razors have nothing to do with the removal of bodily hair. They are called razors because they allow us to deal with the complexity of the world around us by reducing (cutting) the amount of possible explanations to various phenomena. We use them to simplify our thought processes and focus on meaningful explanations without getting lost in a bog of deceiving alternatives. We will examine several of these razors and see how they can be used to deal with the amount of bilge that is often found among claims of conspiracy theories, the pseudosciences, and the paranormal.
1) Occam’s Razor. This is the most well-known of all razors. It was developed by the English philosopher William of Ockham back in the fourteenth century. This razor posits that when faced with choosing between two competing alternatives that explain a phenomenon, we should choose the simplest one. In other words, we should not make things needlessly complicated. Many conspiracy theories such as those which claim that 9/11 was a US government-supported operation or that the US never landed on the moon run afoul of this razor. The sheer number of moving parts that would have to operate just right under a mantle of secrecy to bring about the events alleged in these conspiracies is just too complicated. The simpler explanation is that there was no conspiracy.
2) Hitchens's Razor. The late author, critic, and journalist Christopher Hitchens promulgated the dictum which states that what can be asserted without evidence, can be dismissed without evidence. The implication of this razor is that the burden of proof of a claim is with the claimant. You often hear many proponents of the occurrence of paranormal events declare that these phenomena have not been disproven. By this razor’s criteria, this argument is irrelevant. If you want people to accept a claim, YOU have to prove it is true, and you had better do a very damn good job at it to be taken seriously.
3) Sagan’s Standard. The late astronomer Carl Sagan popularized this aphorism which postulates that extraordinary claims require extraordinary proof. This standard recognizes that not all claims are created equal. Fantastical claims which run counter to scientific laws or mountains of evidence should only be accepted upon the production of truly remarkable evidence. By the metrics of this razor, claims for psychic phenomena, faith healers, and other such things fall short of the level of proof required to accept them.
4) Alder’s Razor. The Australian mathematician Mike Alder published an essay describing this razor, although at the time he called it “Newton’s Flaming Laser Sword” (which is a cooler name). The brutal postulate of this razor (or sword) states that what cannot be settled by experiment or observation is not worth debating. If you have ever had an exchange with a flat Earth proponent and regretted afterwards having lost one hour of your life, you have experienced in the flesh what Alder was talking about.
5) Popper’s Falsifiability Principle. The great philosopher of science Karl Popper coined this famous principle which states that for something to be considered scientific it must be falsifiable. What this means is that there must be a way of proving that a claim is false if it indeed is false, otherwise said claim is not scientific. And if a claim is not scientific, its truthfulness will never be settled by observation or experiment (see Alder’s Razor above). A classical feature of the thinking of those making fantastical claims is that they always move the goalposts. No possible observation or experimental result can prove them wrong. Therefore they can’t be right. On the other hand, science can be right because it can be wrong.
6) Hanlon’s Razor. This particular razor of uncertain origin deals with the motivations behind those who propose fantastical claims. It states that one should never attribute to malice that which is adequately explained by stupidity. While it is true that within the ranks of those who believe in and peddle fantastical claims there are many liars and cheats, this razor reminds us that there are also scores of honest individuals who are just guilty of self-delusion or who have been bamboozled into accepting and defending these claims.
In a recent post I reminded my readers about the dangers of keeping one’s mind too open (i.e. it can easily be filled with trash). Well, I guarantee that if you put these razors between you and the vast vortices of irrationality and trickery that swirl about us, your mind will be spared!
