Distinguishing a clinically pathological "fixed false belief" from a deeply held cultural, religious, or ideological conviction. The standard definition—a belief firmly held despite incontrovertible evidence to the contrary—could technically apply to a devout religious person (belief in an afterlife), a political ideologue, or even a scientist clinging to a paradigm before a revolution (like pre-Copernican astronomers). The line between delusion and non-delusion is often one of social consensus, not a purely objective psychiatric criterion. This makes "delusion" a slippery, culturally-loaded diagnosis.
Example: A man believes government agents are replacing his thoughts with beams from a satellite. This is diagnosed as paranoid delusion. A man believes an omnipotent, invisible being is listening to his thoughts and guiding his life through signs. This is often called faith. The hard problem: The cognitive mechanisms—strong belief resistant to counter-evidence, interpretation of events to fit the belief—may be similar. The differentiation rests on the content's alignment with a society's dominant reality, revealing delusion as partly a social status, not just a brain state. Hard Problem of Delusion.
