If you are feeling overwhelmed by legal language, you are not alone. One common piece of legal lingo you may have come across is post hoc, and it is worthwhile to take a brief moment to understand what exactly it means. Put simply, post hoc is an expression of the Latin phrase, “post hoc ergo propter hoc.” Translated, this phrase means “after this, therefore because of this,” and it is used to describe a logical fallacy where one assumes that because an event follows another, the first event must have caused the second.
For example, imagine that the price of a product is increasing in a store. If someone notices that the store also changed the color of its walls after the price went up, they might jump to the conclusion that the change in price was caused by the change in color. This is an example of post hoc reasoning, as the connection between the two events has not been proven empirically. In some cases, these leaps in logic can lead to false conclusions.
Avoiding Post Hoc Fallacy
The best way to avoid this fallacy is for businesses to use evidence-based methodologies for understanding the relationships between certain events. Turning the example from before, if a business wanted to understand why the price went up, they would need to analyze the data to find out. If the data showed that the color of the walls had no effect on the product’s price, then the business would have avoided the post hoc fallacy.
Ultimately, understanding the post hoc fallacy can help businesses make better decisions and avoid costly missteps. By ensuring that data-driven approaches are taken when forming conclusions, businesses can ward off the sensibility of a gut-feeling and make decisions grounded in evidence.
