Logic Fallacy =  Bad Argument.


If you have every argued with another human (and if you read this blog then I bet that you have) at some point you have certainly heard logic fallacies.

Recognizing and discrediting them is an easy way to win almost any debate. Even when you are in the wrong. But, like a timely joke, it’s so hard to remember them when you need them.

No longer! In this series we present the most common logic fallacies in their most basic forms

Here’s number five in our “Easy-Peasy guide to Winning Arguments and Losing Friends”. But don’t worry, most of your soon to be ex-friends are fallacious losers anyways.

Number 5

No ‘True’ Scotsman

(frequency: rare)
(aka: No true…, Claim of Ambiguity)

Simply put: All A are B.

(opponent gives example of an A that is not B)

Then A is not a real A!

A No ‘True’ Scotsman is when someone has made a universal claim about something that you then refute with an example that contradicts their claim. They then dismiss your example as not representative of their universal claim.  Sound confusing? It’s not. Just look at the examples…




John: “All Atheists hate Jesus!”

Susan: ” I’m and Atheist and I like the things that Jesus said!”

John: “Well, you aren’t a ‘real’ Atheist!”



John: “All Yale graduates are very smart!”

Susan: “George W. Bush graduated from Yale and he was a dumbo!”

John:: “Well, he wasn’t a ‘real’ graduate!”



John: “No Real American would ever torture prisoners!”

Susan: “What are you talking about, what about Guantanamo Bay?”

John: “Those aren’t prisoners!”




Defense: You’re opponent is already on the defense so just keep giving contradictory examples. Eventually their universal argument will crumble.



WARNING:  At some point in order to avoid defeat your opponent will likely try to change the topic. This is called a “Red Herring” and we will discuss it next week!
