Well said. Just because it may be hard to pin down the consequences of the wrong-but-attractive narrative, there probably are consequences, especially on the long term.

Is it really so surprising that these simplistic narratives don't actually accurately describe how the brain works? We should be prepared to admit that the brain is complicated and we don't really know it's functioning at a fundamental level.
