If we're rewriting the quote I'd say that Power's action doesn't even involve a gun. She glances at Science, sees that labcoat + talk = belief + status, and puts on a labcoat and starts talking. Because she is optimizing for status rather than truth the things that Power declares are much more comfortable to believe, and if pressed for proof she just points out that people who wear labcoats brought us prosperity, and who are you to question them?
