When something goes wrong, our minds often search for complicated reasons when a simple one is right in front of us. This idea is known as Occam’s Razor. It says that when there are several possible explanations for something, and they all fit the facts, we should choose the one with the fewest assumptions. It does not mean that the simplest answer is always correct. It simply tells us not to add unnecessary complications.
The name comes from William of Ockham, an English philosopher and Franciscan friar who lived around 1287 to 1347. He was one of the most influential thinkers of the Middle Ages and wrote extensively about logic, knowledge, language and how we should reason about the world. Ockham believed that we should not assume more than necessary when trying to explain something. This approach became an important part of his philosophical thinking. However, he was not the first person to express the idea.
The term “Occam’s Razor” came into use several centuries after his death. The famous saying, “Entities should not be multiplied beyond necessity,” is also not a direct quote from Ockham, although similar ideas can be found in his writings.
Here is an easy example: You come home after work and find your front door open. One possibility is that you forgot to close it. Another is that someone entered your house, opened the door from inside, and left without taking anything. Yet another possibility is that your wife, who was on vacation, returned home without informing you. Unless you find evidence of a break-in or know that your wife has returned, the simplest explanation is that you forgot to close the door. It requires the fewest assumptions. That is why it is called a “razor”: it helps cut away unnecessary explanations.
Occam’s Razor is useful in everyday life. If your phone is not charging, check the charger and power socket before assuming the phone has a serious internal problem. If your car does not start, check whether there is enough fuel or whether the battery is working before assuming there is a major engine problem. If a colleague does not reply to your message, consider that they may simply be busy before assuming they are deliberately ignoring you. If the Wi-Fi suddenly stops working, check the router before assuming that your internet connection has a serious technical problem. The lesson is simple: start with the explanation that requires the fewest assumptions, then look for a more complicated explanation if the facts demand it.
