To refute assertion you need to claim negation of that assertion, which is assertion in itself, as every negation can be rewritten to become affirmation, and vice versa.

It doesn't make it's own claim about all cats, it just adds an anecdote that doesn't conform to the first statement.
- bulbar 6mo agoThe second statement implies the negation of the first though. So OP is correct assuming the term "claim" includes "implies". However, the original argument regarding smoking bias is correct of course.
- wolvesechoes 6mo agoIt negates original assertion. There is no difference between assertion and negation in logic.
- Maxatar 6mo agoThis is not true. Producing a counter example to an assertion refutes the assertion. While you can certainly argue that such a counter example entails the negation of the original assertion, that is not the same thing as claiming the negation of the assertion. Putting forth an argument or demonstrating a counterexample is not the same as asserting all of the logical consequences of that argument.
