This would also be true in e.g. M&A. Even if Cravath's fieriest new partner looked like that I'd hesitate to hire him. Patent law might be an exception, but if I needed to actually go to court, WilmerHale's top guy would still be a liability. Even in a bench trial the judge could see it as disrespectful or look down on my representation because of it. You see my meaning here?
On the table, the surgeon's appearance has little or nothing to do with his ability; in court, a lawyer's appearance can be crucial.
Your surgeon paradox says that if someone is successful despite not looking the part, they must be all the better. But are there lawyers with face tattoos or crazy hair that are considered successful in high stakes criminal law in front of juries? For corporate or patent or tax law, that is so much about a deep intimate understanding of hundreds of thousands of pages of ultra specific “loopholes” and optimization strategies, I would not be surprised if there were lawyers who look very alternative. But criminal law lives and dies on persuading people who are not legal experts.
