Not All Experts Are Equal

Being an expert in one field does not make someone an expert in all fields. A physicist commenting on climate science is more credible than a physicist commenting on economics. Domain expertise matters.

Evaluating Expert Credentials

  • Is their expertise in the relevant domain?
  • What are their credentials (degrees, publications, positions)?
  • Do they have a track record of accuracy?
  • Are they recognized by peers in their field?
  • Do they have conflicts of interest?
  • Are they representing the consensus view or a minority position?
Domain Expertise:Deep knowledge and skill in a specific field, as opposed to general intelligence or expertise in other areas.

When Experts Disagree

Expert disagreement is normal in science — it drives progress. But there is a difference between genuine scientific debate (where evidence is contested) and manufactured controversy (where a small minority of experts are amplified to create the impression of more disagreement than exists).

Manufactured Controversy:The deliberate amplification of minority expert views to create the false impression of widespread scientific disagreement.
False Balance

Media sometimes gives equal coverage to majority and minority expert views, creating a false impression of balance. 97% of climate scientists agree on human-caused climate change — giving equal time to the 3% creates false balance.
