WE ARE BOTH INFORMED AND DECEIVED BY SUGGESTION
We should not be surprised, if experience is transferred by the process of using names of properties by means of suggestion, that those who would master deception would do so by the same process of suggestion.
Meaning, that one can seek to inform or to deceive by the same means. And that some of us should specialize in the suggestion of truth, some in the suggestion of honesty, some in the suggestion of error, and some in the suggestion of falsehood, should not surprise us.
What should surprise us is how willingly susceptible to suggestion we humans are if suggestion confirms our natural cognitive or moral biases. Nor should it surprise us if others develop specialization in suggestions that invoke our moral biases.
