 The different goals arguer’s try to achieve via argument may make their success and legitimacy turn on norms and rules that add to (or subtract from) the traditional strictures that guide argument evaluation. In some circumstances, it makes ultimatums, exaggerations, threats and insults a permissible element of arguing. In sharp contrast, they are unacceptable in attempts to determine what is true from a scientific point of view, where such behaviors are instances of the fallacy ad baculum.
