The logical fallacy of innuendo, or implication, occurs when a conclusion is suggested to be true without directly stating the point. This is a fallacy because it is a deceptive tactic. Innuendo is generally used as a substitute for evidence. In other words, the innuendo technique is used as the only proof for a claim. It is often more persuasive than a straightforward statement because a clear statement is easier to evaluate for logical fallacies, to realize that a claim (implied) has no basis, no proof. Note that this is different from simply being unclear. What makes this a fallacy is that there is no evidence and the use of innuendo is a mechanism to hide the fact that there is no real evidence.
