No True Scotsman
In one line When a counterexample appears, weaken the claim instead of redefining the group to shut it out.
The no true Scotsman move protects a sweeping claim by redrawing its group. “No real artist works for money.” Then someone names an artist who does. “Then she is not a real artist.” The counterexample is ruled out by definition.
The name comes from the philosopher Antony Flew. He imagined a Scot who reads of a crime and says no Scotsman would do such a thing. Shown a Scot who did, he replies that no true Scotsman would. The claim can now never be wrong, and so it says nothing about real Scots.
The honest options are to weaken the claim, to “most” or “many,” or to give it up. If a group needs a definition, set it out before looking at the cases, and apply it evenly.
The real runner
Noor says, “Real runners never walk during a race.” Her friend mentions a coach who walks through the water stations in every marathon.
“Then she is not a real runner,” Noor says, and stops. The coach has run thirty marathons. Noor rewrites her claim: “Many runners try not to walk, but walking breaks are a common and sensible plan.” It is a smaller claim, and a true one.
Try this today When you hear “no real” or “no true,” ask what would count, decided before looking at the cases.
