Correlation is Not Causation

I ran across yet another article that confuses correlation with causation. This time it is KSL saying Why You Should Rethink Your Netflix Binge There was a study done that noticed a strong correlation between people who watched a lot of television and those who had less cognitive function later in life. The trouble is the study has no way to show that the television watching caused the lower cognitive function. It could just as easily be true that people who have lower cognitive function are more likely to watch lots of television. I know that for me one of the biggest signs of depression is that I binge watch Netflix. When the depression backs off, I’m just not interested in watching that much. I’d rather be doing other things. For me it is definitely the depression that causes the binge watching not the other way around. One anecdotal example is not proof of anything, yet it may lead to a line of inquiry. What if we treated habitual binge watching television as a symptom? What if when we saw it in a person’s life and sought out where else they might need help or healing? Symptoms vanish without any work if the core condition is healed.
