Therefore A is the cause of B. This fallacy requires that there is not, in fact, a common cause that actually causes both A and B. This fallacy is committed when a person assumes that one event must cause another just because the events occur together.
More formally, this fallacy involves drawing the conclusion that A is the cause of B simply because A and B are in regular conjunction (and there is not a common cause that is actually the cause of A and B).
For example, a problem child might be the cause of the parents being short tempered or the short temper of the parents might be the cause of the child being problematic.
The fallacy of the single cause, also known as joint effect or causal oversimplification, is a logical fallacy of causation that occurs when it is assumed that there is one, simple cause of an outcome when in reality it may have been caused by a number of only jointly sufficient causes.
For instance, after a school shooting, editorialists debate whether it was caused by the shooter's parents, TV violence, stress on students, Hollywood or the accessibility of guns.
In other words, the possible causes are assumed to be "A or B or C" when "A and B and C" or "A and B and not C" (etc.) are not taken into consideration.
