Otherwise, it is unsound, as in the "bats are birds" example. If the premises of an inductive argument are assumed true, is it probable the conclusion is also true.
Argumentation schemes have been developed to describe and assess the acceptability or the fallaciousness of defeasible arguments.
Or perhaps counter-examples that raise questions about how the argument is viewing basic issues. A crucial part of critical thinking is to identify, construct, and evaluate arguments. In everyday life, people often use "argument" to mean a quarrel between people.
