Logical Fallacy of the Week, Week 24: Circular Cause and Consequence

...

This is one of the most important fallacies we should be looking at. This is one used unendingly by the greenies and their junk scientist allies. There is a lot more to this one so please follow the link. It is imperative that we understand this fallacy and immediately recognize it when it is used. This is not science; it is easy to recognize; it is easy to overcome.  We need to get that!

Correlation does not imply causation (Circular cause and consequence)

"Correlation does not imply causation" (related to "ignoring a common cause" and questionable cause) is a phrase used in science and statistics to emphasize that correlation between two variables does not automatically imply that one causes the other (though correlation is necessary for linear causation in the absence of any third and countervailing causative variable, and can indicate possible causes or areas for further investigation; in other words, correlation is a hint).

The opposite belief, correlation proves causation, is a logical fallacy by which two events that occur together are claimed to have a cause-and-effect relationship. The fallacy is also known as cum hoc ergo propter hoc (Latin for "with this, therefore because of this") and false cause. By contrast, the fallacy post hoc ergo propter hoc requires that one event occur before the other and so may be considered a type of cum hoc fallacy.
