Patholighting

A vicious form of gaslighting that involves pathologizing the other person—labeling their thoughts, feelings, or behaviors as symptoms of mental illness, thereby dismissing everything they say without engaging with its content. Patholighting happens when you express a legitimate concern and are told you're "being paranoid," when you disagree with someone and are told you're "delusional," or when you question authority and are told you're "schizophrenic." The goal is to make you doubt not just your perception of reality, but your own sanity. Once you've been pathologized, nothing you say matters—it's just the illness talking. Patholighting is especially common in online arguments, where "touch grass," "seek help," and "you're clearly mentally ill" serve as conversation-enders that require no engagement with the actual argument.

Example: "She pointed out logical flaws in his argument, and he patholighted her immediately. 'You're so obsessed with this,' he said. 'It's not normal. You might have some kind of disorder.' Her points remained unaddressed, her logic unanswered, but now she was also worried that maybe she was too invested. The patholighting had worked: she was defending her sanity instead of her argument."
