What is the Cum Hoc Ergo Propter Hoc Fallacy?

Cum Hoc Ergo Propter Hoc is Latin for “with this, therefore because of this”. This fallacy involves assuming a causal relationship between two events or variables based solely on their temporal coincidence. In other words, we mistakenly conclude that one event causes the other simply because they happen at the same time.

Examples:

1. Coincidence: “I wore my lucky socks to the interview and got the job! Those socks must be good luck!” (This assumes a causal relationship between wearing the socks and getting the job, without considering other factors that might have contributed to success.)
2. Superstition: “Every time I forget to knock on wood, something bad happens. Knocking on wood must prevent bad things from happening!” (This assumes a causal relationship between knocking on wood and preventing bad events, based solely on a coincidence of timing.)
3. False attribution: “I started taking vitamin C supplements and my cold went away! Vitamin C must be the cure for the common cold.” (This assumes a causal relationship between taking vitamin C and recovering from the cold, without considering other factors that might have contributed to recovery.)

Why is this fallacy so common?

The Cum Hoc Ergo Propter Hoc Fallacy is a common mistake because it’s easy to confuse correlation with causation. Our brains are wired to look for patterns and connections between events, which can lead us to mistakenly assume causal relationships.

How to avoid the Cum Hoc Ergo Propter Hoc Fallacy:

1. Look for alternative explanations: Consider other factors that might have contributed to the coincidence.
2. Seek out empirical evidence: Look for scientific studies or data that support a causal relationship between the two events or phenomena.
3. Be cautious of anecdotal evidence: Don’t rely solely on personal experiences or stories to establish a causal connection.

Real-world implications

The Cum Hoc Ergo Propter Hoc Fallacy can have significant consequences in various domains, such as:

1. Medicine: Failing to recognize the fallacy can lead to misattributed causes of diseases and ineffective treatments.
2. Business: Incorrectly attributing success or failure to specific actions or events can lead to poor decision-making and resource allocation.
3. Environmental management: Misunderstanding causal relationships between human activities and environmental changes can hinder effective conservation efforts.
