According to a study by the American Medical Association, men with bald spots have three times the risk of heart attack as men with a full head of hair. Strange as it may seem, it looks as if baldness is a cause of heart attacks. Kind of Reasoning: Flaws (if any) in Reasoning:

This is an example of causal reasoning.

Explanation:

It is an example of causal reasoning because the statement is relating two facts as if one would be the cause of the other. In this case, being bald is the cause, and the effect is a heart attack. The flaw in this reasoning is that there is not enough evidence to prove that baldness can increase the risk of heart attacks. That is something that science has to investigate to check that this statement is not a fallacy of false cause.
