The error of privileging formal, deductive logic above all other ways of knowing (empathy, intuition, experiential knowledge, moral reasoning) and dismissing any argument that doesn't fit into a neat syllogism as "illogical" and therefore invalid. It's a bias that mistakes a specific tool for the entire toolbox of human understanding, often to coldly justify inhuman conclusions.
Example: "Logically, a corporation's only duty is to maximize shareholder value. Therefore, laying off 10,000 people to boost stock price is not just permissible, it's illogical not to do it." This Logical Bias uses a narrow, amoral logical framework to justify a human catastrophe, dismissing ethical concerns as sentimental "illogic."
