A good mic doesn’t make an opinion true. Confidence isn’t evidence.

Clear audio, a steady voice and an unhesitating delivery are all things you can buy or practise, and none of them touch whether the content is right. Your brain treats fluency as a signal of competence, because in ordinary life it often is, which makes this an easy trick to fall for. The people who sound most certain are frequently the ones who have examined it least.

When something sounds obviously true, ask what would have to be the case for it to be wrong. Look for the number or the source underneath the claim. Notice whether anybody you listen to ever admits to being unsure.
