Correlation and causation get confounded because our brains rely on our “vision”, what we see is what we believe. (BTW, this discussion began yesterday with this post- there will be two more in a row.) And, most of our causal explanations are naïve (even if they seem complex)- they rely on the fallacy of a single cause (or two). These oversimplifications help us understand phenomena, so we are positive they are correct.
