Psychologists studying courtroom behavior noticed that the most persuasive expert witnesses are rarely the most credentialed — they're the ones who visibly update their position when challenged. This maps onto something the pragmatist philosopher William James argued in his lectures on 'The Will to Believe': genuine intellectual credibility comes not from projecting certainty, but from demonstrating that your conclusions are responsive to evidence. James called this the difference between a belief held as a live hypothesis versus one held as a dead dogma — the first stays tethered to the world, the second floats free of it. In trial science terms: a witness who says 'that's a fair point, and here's how I account for it' signals to jurors that their testimony is constructed from reality rather than advocacy. The practical move is to rehearse not just your strongest points, but your most honest concessions — and deliver them with the same preparation and calm as your direct examination.

Think of a position you've argued recently — what would a genuine, well-reasoned concession to the opposing side actually sound like, and why haven't you said it aloud?
