Philosophers have theorized about causation since well before Aristotle, who distinguished several types of causation: For example, a wood carving is made by an artist the efficient cause by chiseling a piece of wood the material cause for the purpose of creating a beautiful object the final causearriving at something that has the properties of a wood carving the formal cause. Although Aristotle's typology framed discussions of causation until the scientific revolution and in some circles even until David Humethe focus settled onto analyzing efficient causation and in particular on understanding the kinds of substances that might interact causally. Discussions of causation thus became entangled with the metaphysics of substance, and positions ranged all the way from Baruch Spinozawho claimed there is only one type of substance, to Gottfried Wilhelm Leibnizwho claimed there was an infinity of unique substances, one per monad.

Mistakes in Thinking About Causality

Usage[ edit ] In logicthe technical use of the word "implies" means "is a sufficient circumstance for". Indeed, p implies q has the technical meaning of the material conditional: That is "if circumstance p is true, then q follows. The idea that correlation and causation are connected is certainly true; where there is causation, there is a likely correlation.

Indeed, correlation is used when inferring causation; the important point is that such inferences are made after correlations are confirmed as real and all causational relationship are systematically explored using large enough data sets.

For any two correlated events, A and B, the different possible relationships include[ citation needed ]: A causes B direct causation ; B causes A reverse causation ; A and B are consequences of a common cause, but do not cause each other; A and B both cause C, which is explicitly or implicitly conditioned on; A causes B and B causes A bidirectional or cyclic causation ; A causes C which causes B indirect causation ; There is no connection between A and B; the correlation is a coincidence.

Thus there can be no conclusion made regarding the existence or the direction of a cause-and-effect relationship only from the fact that A and B are correlated.

Determining whether there is an actual cause-and-effect relationship requires further investigation, even when the relationship between A and B is statistically significanta large effect size is observed, or a large part of the variance is explained.

Examples of illogically inferring causation from correlation[ edit ] B causes A reverse causation or reverse causality [ edit ] Reverse causation or reverse causality or wrong direction is an informal fallacy of questionable cause where cause and effect are reversed.

The cause is said to be the effect and vice versa. Example 1 The faster windmills are observed to rotate, the more wind is observed to be. Therefore wind is caused by the rotation of windmills. In this example, the correlation simultaneity between windmill activity and wind velocity does not imply that wind is caused by windmills.

Wind can be observed in places where there are no windmills or non-rotating windmills—and there are good reasons to believe that wind existed before the invention of windmills.

Therefore, high debt causes slow growth.

This argument by Carmen Reinhart and Kenneth Rogoff was refuted by Paul Krugman on the basis that they got the causality backwards: Example 4 In other cases it may simply be unclear which is the cause and which is the effect. Children that watch a lot of TV are the most violent.

Clearly, TV makes children more violent. This could easily be the other way round; that is, violent children like watching more TV than less violent ones. Example 5 A correlation between recreational drug use and psychiatric disorders might be either way around: Gateway drug theory may argue that marijuana usage leads to usage of harder drugs, but hard drug usage may lead to marijuana usage see also confusion of the inverse.

Indeed, in the social sciences where controlled experiments often cannot be used to discern the direction of causation, this fallacy can fuel long-standing scientific arguments. Example 6 A historical example of this is that Europeans in the Middle Ages believed that lice were beneficial to your health, since there would rarely be any lice on sick people.

The reasoning was that the people got sick because the lice left. The real reason however is that lice are extremely sensitive to body temperature.Breathing secondhand smoke can cause coronary heart disease, including heart attack and stroke.

The raison d’etre of strategy is the idea that our the statements describing the causes of disease make very different arguments.

Dec 14,  · Quasi-causation is “possible causation”, and includes negative causation-type events (e.g., omissions, preventions, or just complete non-occurrences). The doctor rushing to his code-blue patient and resuscitating him caused him not to die. For example, say a person dies when two bullets pierce his heart at the same time. Or two radios, tuned to the same station and both turned on, begin playing the same music when the station begins its broadcasting day. Cardiovascular Stress: Increased heart rate and blood pressure.
