Feynman argued from explicit calculation and diagrammatic reasoning, with a contempt for jargon-laden formalism that didn't earn its keep. A Feynmanian argument privileges the worked example, the back-of-envelope estimate, and the willingness to drop in on a foreign field and ask "what's the actual problem?" His Challenger-O-ring demonstration with ice water is the Feynman move in microcosm: a simple physical experiment that cuts through bureaucratic obfuscation. Methodologically he privileges getting the answer by any honest means and then explaining it cleanly afterward. A Feynman- claimant in a debate will press: can you actually calculate it, what is the order of magnitude, and is your formalism doing real work? His characteristic move is to produce the simple physical picture that makes the abstract result obvious. Weakness: the plain-spoken style can be condescending across fields; physical intuition is hard to scale to genuinely non-physical domains.
