By using counterexamples to show that certain conjectures are false, mathematical researchers can then avoid going down blind alleys and learn to modify conjectures to produce provable theorems.en.wikipedia.org/wiki/CounterexampleA counterexample is a specific example for which a statement is untrue. The existence counterexample proves the statement is false, even if it is often, mostly, or almost entirely true.www.storyofmathematics.com/counterexample/This proof structure allows us to prove that a property is not true by pro-viding an example where it does not hold.www.math.toronto.edu/writing/Counterexample.pdfThe "counterexample method" is a powerful way of exposing what is wrong with an argument that is invalid. If we want to proceed methodically, there are two steps: 1) Isolate the argument form; 2) Construct an argument with the same form that is obviously invalid. This is the counterexample.www.thoughtco.com/prove-argument-invalid-by-co…
