Deductive Fallacy


A deductive fallacy, or logical fallacy, is defined as a deductive argument that is invalid. The argument itself could have true premises, but still have a false conclusion. Thus, a deductive fallacy is a fallacy where deduction goes wrong, and is no longer a logical process.

Statement 1: Most of the green circle is touching the red circle.
Statement 2: Most of the red circle is touching the blue circle.
Logical fallacy: Since most of the green circle is touching the red, and most of the red circle is touching the blue, most of the green circle must be touching the blue. This, however, is a false statement.
