Look for the objective truth before trusting authorities

Evaluate the truth of a statement.
Evaluate it based on its underlying facts, without regard to the authority's personal qualities or social status.

Separate between real and false experts.
Anyone can call themselves an expert.

Always consider reliability, credibility, sensibility, and bias.
Authority may be interested in persuading you to believe something in their interests. To ensure their trustworthiness, authorities often mention weaknesses before strengths and provide information that seems contrary to their interests.
