The fallacy of believing that a conclusion derived from a formally valid logical structure is necessarily true or meaningful in the real world. This bias venerates the syntactic correctness of an argument while being blind to the factual inaccuracy of its premises or its deliberate abstraction from reality. Perfect logic, perfectly wrong.
Example: "Premise 1: All birds can fly. Premise 2: A penguin is a bird. Conclusion: Therefore, penguins can fly." The logical bias is the insistence that the airtight logic of the syllogism somehow challenges biological reality, or that pointing out the false premise is "cheating" at the logical game. Form is prized over substance.
