A "thin argument" refers to a type of reasoning that lacks depth or substantial evidence. It often relies on superficial claims or generalizations rather than detailed analysis or robust support. This can make the argument less convincing and may lead to misunderstandings or oversimplifications of complex issues. In discussions, thin arguments can be identified by their reliance on clichés or emotional appeals instead of logical reasoning. For example, a thin argument about climate change might state, "It's just getting warmer," without addressing the scientific data or the implications of rising temperatures on ecosystems and human life.
