What does the conversation imply?

M: Have you ever heard the saying, "Clothes make the man"? It might be truer than we imagine.
W: When a police officer or firefighter puts on their uniform it must affect their psychology. It probably gives them a sense of responsibility and authority.
M: Absolutely. When a judge puts on that heavy black robe it transmits an image of power, but it also serves a reminder to the judge of the responsibility of their position.

W: I’ve got a question. How do you know a gene is a disease gene?
M: Well, as I say, after an analysis we have a list of candidate genes that could be a disease gene. We then send off these results to biologists who will confirm our findings.
