Where Do Babies Come From?

According to European folklore, popularized by a fairy tale, storks are responsible for bringing babies to new parents. This probably came from observation in certain European countries, such as Norway, Netherlands or Germany, that storks nesting on the roofs of households were believed to bring good luck, as the possibility of new births. People love stories, but correlation simply means that there is a relationship between two factors that tells nothing about the direction of said relationship, if any. Another possibility is simple coincidence. Let us say that it’s possible that one factor causes another. It’s also possible that the inverse occurs. And maybe both are being caused by a third. The main point is that there is a fundamental confusion between correlation and causality. A correlation doesn’t prove a cause by itself. During these times of abundant fake news, it is necessary to warn folks of the fallacy of mistaking correlation for causation.
