It’s quite amazing how many scientific facts about human beings that primitive people have learned through the centuries by trial and error and observation. Most traditional wisdom about the human condition has a large aspect of truth to it. Humans are not stupid. Human groups do not learn lies as traditional wisdom over the centuries. Instead they tend to learn truths.
I call this, “Your grandmother was right!” It is important even in our modern era to pay attention to the traditional wisdom of ages that groups of humans have. My experience has shown that traditional wisdom, while not necessarily PC, often has a huge Slab of Truth packed into its Knowledge Sandwich. The fact that traditional wisdom is so often not PC is why the Cultural Left hates traditional wisdom so much.
