Well, if a person is unwilling to read and learn, then nothing will
change his mind.

I think that's a bit unfair. Whether a person was taught correctly or
incorrectly is a matter of chance; when someone later seeks to change
his mind, what authoritative evidence is available?

Many people want to learn, but they aren't sure whom to trust. In the
end, most are persuaded by the highest status individual with a firm
opinion.
