Use ChatGPT Work to turn an approved research question, population definition, sampling or recruitment plan, instrument, and existing findings into a study brief or findings review that separates observations, estimates, limitations, and decisions still open. It can organize evidence and challenge the design; it cannot invent a population, recruit or contact participants, obtain consent, fabricate responses, turn a convenience sample into the market, or state a finding as causal when the study cannot support it. The attached figures are projected role-task priors, not measured ChatGPT adoption by marketing managers, so they support a controlled research-planning trial rather than a claim about current practice.
