AI can help marketers draft and adapt content faster, but faster production does not by itself mean stronger strategy or better campaign results. The claim that marketing got faster without getting better is a useful practitioner thesis—not a conclusion established across marketing teams. The evidence is mixed by task: some studies find productivity and quality gains in bounded work, while another finds weaker results when people use AI beyond its capabilities.
What “faster” and “better” mean in marketing
Speed can mean less time to produce a first draft, more variations from the same brief, or quicker repurposing across channels. It does not necessarily mean less time from brief to launch: review, approval, coordination, and measurement still take work.

Quality also has more than one meaning. A piece of copy can be clear and on-brand yet fail to influence the intended customer behavior. Output quality is not the same as campaign effectiveness, and neither alone establishes business impact.
Kath Pay’s commentary makes a workflow argument: AI can accelerate execution while leaving the decisions that shape a campaign unresolved. Her line, “The output quality still depends on the thinking quality that went into it,” is an argument about the importance of the brief and judgment, not a measured industry-wide result.
#1 Best Overall
What the studies do—and do not—show
| Evidence | What was studied | What it supports | What it does not establish |
|---|---|---|---|
| Gastmann and Bastos (2025) | Interviews with 20 social media professionals and a follow-up experiment using ChatGPT to devise strategies for two companies. | The authors report productivity potential and high-quality strategy output on brand fit, fit to business challenges, and strategic flexibility. They also flag intellectual-property and data-protection requirements. | A general improvement in marketing effectiveness across companies or campaigns. |
| Noy and Zhang (2023) | A randomized experiment involving 453 college-educated professionals completing occupation-specific writing tasks. | In those tasks, average completion time fell by 40% and assessed output quality rose by 18%. | Those figures do not measure campaign performance or marketing quality overall. |
| Organization Science field experiment (2026) | A preregistered field experiment with 758 knowledge workers performing different tasks. | Participants using AI performed better on tasks judged to be within the tested capability frontier, but were less likely to produce correct answers on a complex managerial task outside it. | A marketing-wide verdict; the result shows performance can depend on the task and the tool’s capabilities. |
These results measure different people, tasks, and outcomes, so they should not be combined into one estimate of marketing performance. Taken together, they challenge both extremes: AI is not merely a faster typing aid, but speed or success on a bounded task does not prove that an entire marketing operation is better.
Why producing more can leave the real bottleneck untouched
Unclear briefs generate more options, not necessarily better choices
If a team has not agreed on the audience, proposition, or intended behavior, AI can generate many plausible directions without resolving which one matters. More variants may then create additional review and approval work. That is a practical risk identified in Pay’s commentary, not a measured finding about every team.
Production is only one part of the workflow
Drafting is visible and easy to accelerate. But a campaign also requires agreement on what is being promised, who needs to approve it, which claims can be supported, and how the result will be judged. Automating copy creation cannot settle those questions on its own.
More content does not automatically mean more strategic capacity
Time saved on routine drafting becomes useful only if the team uses it for higher-value work—such as customer understanding, testing assumptions, or interpreting results. Otherwise, it can simply increase the volume of content moving through the same decision process.
How to use AI to strengthen the brief before generating copy
- Define the communication’s job. State where it fits in the customer journey and what the audience should think, feel, or do next.
- Describe the audience’s starting point. Specify what customers already know, what they may doubt, and what constraints shape their decision. Separate evidence from assumptions.
- Make the proposition explicit. Identify the offer or idea, why it should matter to this audience, and what evidence supports the claim.
- Set decision criteria before asking for options. Choose the standards that will distinguish a useful response—for example, customer relevance, brand fit, strategic fit, and substantiated claims.
- Set the success measure. Decide how the team will tell whether the communication influenced the intended behavior. Choose a measure that fits the campaign’s objective rather than treating content volume or speed as a result.
- Ask AI to find gaps before it drafts. Have it surface missing assumptions, likely customer questions, and places where the brief relies on unsupported claims. Treat its questions as prompts for human review, not proof that the brief is complete.
- Generate alternatives against the criteria. Once the brief is clear, use AI to explore different approaches. Ask it to explain how each option serves the audience and objective; then have people choose and revise.
- Review claims and customer fit. Check factual assertions, context, tone, and fit with actual customer needs before publication. Keep humans accountable for strategic choices.
- Interpret outcomes, not just outputs. Use AI to organize campaign evidence if useful, but examine what changed and whether the campaign created demand, captured existing demand, or merely discounted it.
Where human judgment remains essential
AI can help expose gaps, organize information, and produce options. It cannot take responsibility for whether the evidence justifies a claim, whether an audience insight is sound, or which strategic trade-off a team should accept. As Pay puts it, “AI can’t resolve these judgment questions. But it highlights the need for humans to step in.” That is her commentary on the role of human judgment, not an empirical conclusion that AI has no strategic use.
The practical test is not simply whether a team can make more assets in less time. It is whether faster work leaves more room for sound decisions—and whether the chosen communication produces the outcome the team set out to influence.
