Use when the user invokes "best practice", "standard approach", "everyone does X", "the industry does Y", or when the default answer smells like received wisdom rather than evidence. Also use when hunting for contrarian advantage — "why does nobody do X", "is the conventional answer here actually right". Inventories beliefs, audits the evidence behind each, rebuilds from ground truth, and surfaces where convention is wrong. Invoke whenever you catch the default answer being a cliché.
