"Liar" and "expert" are on different axes.

• josephorjoe 6y ago
  Exactly. An expert is someone whose statements are valued because they are trusted to offer valuable insight and expertise. A liar is someone whose statements have no value because they cannot be trusted. A person with expertise (useful domain knowledge) cannot be considered an expert if they are not trusted. Their expertise can still be acknowledged, but once they have lied, their statements cannot be trusted and the listener has to be concerned about the motivation behind the statement rather than reassured by the expertise of the person making the statement. It does not matter how brilliant a car mechanic is if my first thought after him telling me "your car needs new brakes" is "does my car really need new brakes or does my mechanic have a boat payment he needs to make this week?"

  An expert is just someone who can be trusted to lie. Or perhaps that's just a professional. Otherwise you are just a practitioner.
