>>14153292according to psychiatric science, it is fundamentally impossible to convince a person with narcissistic personalty disorder that they are a person with narcissistic personalty disorder no matter how much evidence is available.
for example, the scientists who put up the now infamous glacier park signs would never in a million years go out in public and say "sorry, we were wrong about that, our science isn't as omniscient as we thought it was" instead they sneak away like embarrassed children trying to avoid responsibly for their past actions while still trying to assert their imaginary "scientific" omniscience, omniscience which the scientific method itself says is irrational, but they ignore that part.
