Correlation Vs. Causality and the Flawed Use of Science

I've had exchanges with PhDs and Medical Doctors who clearly either didn't read the research they were quoting, or they simply didn't understand it. In either case, that's a frightening scenario.  If you do not have a detailed understanding of a study, then you have no business quoting it as evidence of your opinion. More importantly, you have no business making specific recommendations, or drawing hard conclusions based on research you do not fully understand.

Here is an excellent video that illustrates one reason why people who do not have a background in science and scientific research should be very careful about quoting studies as evidence for anything. Too many people regularly quote studies that only show a correlation as proof of causation.
