Governance and AI

We remain in Weeks 3 to 5: Content and Media. Week 3 gave the campaign its visual argument. This week gives it a verbal argument. Every copy decision must trace back to the same canvas, the same hierarchy stage, and the same processing route that governed Week 3.

Today’s Agenda

Lecture: eleven theory and practice sections

  1. Why copy is itself a campaign decision
  2. The theory of planned behaviour: diagnosing the weakest link
  3. ELM and HSM: central/systematic versus peripheral/heuristic
  4. Anchoring and priming: cognitive shortcuts that operate below awareness
  5. Framing theory: gain frames versus loss frames
  6. Cialdini’s six principles: the persuasion mechanism map
  7. Copy structure: hook, claim, evidence, call to action
  8. Tone, readability, and accessibility
  9. Headlines and the first three seconds
  10. Message testing: designing a minimum-viable A/B test
  11. AI copy generation: uses, limits, and evidence standards

Tutorial preview

You will build a real ad mockup in Canva:

  • Diagnose your audience’s TPB weak link and write a four-line copy brief
  • Build the hook, claim, evidence, and call to action in Canva (40-minute sprint)
  • Scroll-test a partner’s phone, then answer three critique questions
  • Fix, write the message test plan, and check readability and contrast
  • Vote live on Hook A versus Hook B, then complete the copy decision record

Learning Objectives (1 of 2)

After studying this chapter, you should be able to:

  1. Apply the theory of planned behaviour to identify the weakest link, attitude, subjective norm, or perceived behavioural control, in an audience’s path from belief to action.
  2. Distinguish the ELM’s central and peripheral routes from the heuristic-systematic model’s systematic and heuristic processing.
  3. Identify anchoring and priming effects in a campaign context and apply each deliberately.
  4. Apply framing theory to write the same core claim in gain-frame and loss-frame versions.
  5. Use Cialdini’s six principles to identify the persuasive mechanism most appropriate to the target segment and hierarchy stage.

Learning Objectives (2 of 2)

After studying this chapter, you should be able to:

  1. Construct a four-part copy structure (hook, claim, evidence, call to action) that passes a tone, readability, and accessibility check.
  2. Write a headline matched to the visual hierarchy and the audience’s processing route.
  3. Distinguish a message test from a creative preference test.
  4. Evaluate AI-generated copy against the evidence standard.
  5. Apply the evidence framework: classify message choices as evidence-based, inferred, or assumed.

Objective 10 applies the module’s evidence discipline to words. An untraceable claim gets labelled as an assumption.

Why Copy Is a Campaign Decision

Digital marketing copy is a strategic decision. The exact words used to frame a claim change whether the audience perceives the offer as a gain or a loss, whether they trust the source, and whether they act or defer.

A message written for the wrong audience state fails structurally, whatever its style.

The Theory of Planned Behaviour

A person’s intention to act, and so the behaviour itself, is predicted by three independent factors: attitude toward the behaviour, the subjective norm they perceive around it, and their perceived behavioural control over performing it.

Ajzen, 1991. A diagnostic tool: it identifies which factor is weakest, so copy can target that link specifically.

Processing Routes: ELM and HSM

Your Week 2 canvas already records an ELM processing route: central for an audience that evaluates arguments, peripheral for an audience that responds to cues. The heuristic-systematic model, developed independently by Chaiken, describes the same split with a different emphasis.

ELM tells you whether to write for argument or for cue. HSM tells you which specific heuristic to supply.

Anchoring and Priming

Anchoring is the tendency to rely too heavily on the first number encountered when making a subsequent judgement. Priming is the tendency for exposure to one stimulus to shape how a person interprets a subsequent, unrelated stimulus.

Both effects were documented in the same research programme that produced prospect theory (Tversky and Kahneman, 1974), and both operate below conscious evaluation.

Anchoring and Priming: The Diagrams

Anchoring in Real Campaigns

Priming in Real Campaigns

Live: Anchoring on a Real Hotel Map

Point out live: the price pin on every marker (an anchor before a single word is read), the “great deal, X% less than usual” badge (an anchor against the site’s own usual price), and the sponsored listing at the top of the list (an authority/priority cue, not a price signal).

Framing Theory

The same information can produce different responses depending on how it is presented. Information presented as a potential loss generates stronger motivation to act than the same information presented as a potential gain.

Kahneman and Tversky, prospect theory (1979). Entman, framing theory (1993).

Gain Frame vs Loss Frame

A Textbook Framing Example

Vote: which label would make you pick up the pack? Both describe the identical product.

Cialdini’s Six Principles of Influence

Six principles describe the psychological mechanisms through which persuasion operates: reciprocity, commitment and consistency, social proof, authority, liking, and scarcity.

Cialdini, 2007. A diagnostic: deploy the one or two principles that fit the stage.

Applicability Across the Hierarchy

Cialdini’s Six Principles: Reference Wheel

Copy Structure: Hook, Claim, Evidence, Call to Action

Every effective campaign message has four functional parts. A message with three of the four fails at a specific, predictable point.

The four-part structure is a decision sequence: write each part on purpose, in order.

The Four Parts

Part Central-route version Peripheral-route version
Hook Surfaces a specific, articulated problem Creates a visual or social cue
Evidence Named statistic, testimonial, accreditation Partner logo, award badge, user count
Call to action “See the programme structure” (Knowledge) “Find out more” (Awareness)

Tone, Readability, and Accessibility

The four-part structure governs what a message says. Tone, readability, and accessibility govern whether the audience can receive it at all.

A message with all four parts still fails if the sentence is too dense to parse in the three seconds a scrolling audience gives it.

Before and After a Readability Pass

Free tools, no sign-up: Hemingway Editor (hemingwayapp.com) for reading grade level; WebAIM Contrast Checker for the call-to-action colour pair.

Headlines and the First Three Seconds

The audience’s decision to continue or stop is made in the first few seconds of exposure, driven by whether the opening line answers: “Is this for someone like me, in my situation, with my concern?”

A headline performs three functions simultaneously: identifies the audience, names the problem, promises a resolution.

What Makes a Headline Work

Function Example
Identifies the audience “For marketing officers in Maldivian hospitality…”
Names the problem or desire “…who need a credential that travels…”
Promises a resolution “…a fifteen-week programme that produces a portfolio you can show at any interview.”

Context adaptation: a Google Search headline answers a query the audience already typed. A Facebook Feed headline must create the need before it can address one. A headline optimised for one context tends to underperform in the other.

Message Testing

A message test measures audience response to two or more versions of a message. It settles the question with data, not with a team vote on preference.

A hypothesis paired with a decision rule is an experiment; a hypothesis alone is an interest.

Five Components of a Minimum-Viable Test

  1. One variable changed. Test the hook only, or the call to action only, or the frame only.
  2. A stated hypothesis. “Variant A will produce a higher click-through rate because [rationale linked to TPB, framing, or hierarchy stage].”
  3. An outcome metric matched to the hierarchy stage. Awareness: reach. Knowledge: click-through. Preference: engagement with comparison content. Conviction: conversion rate.
  4. A minimum sample size. 300 to 500 impressions per variant is typical for a campaign this size.
  5. A decision rule, fixed before the result is known. “If Version A achieves a higher click-through rate at 95 per cent confidence, we adopt Version A.”

AI Copy Generation: Uses, Limits, Evidence Standards

Permitted and useful Restricted
Generate structural variants (same claim, different framings) Generate audience facts that lack documentation
Draft opening lines for review and selection Generate testimonials or social proof never collected from real customers
Check whether a message stays internally consistent with the brief Insert specific claims that lack verification from a cited source
Generate a list of audience objections to test against Submit AI copy without human review against the evidence standard

Every AI-generated copy element used in any submission must appear in the prompt log, with the exact prompt, the output, and the student’s decision about what was accepted, rejected, or revised.

Worked Example: Villa College Certificate

Vote: Which One Stops You?

Hands up: which one would make you stop scrolling? Why?

Two More Worked Examples

The same decision sequence applies to any campaign category. Two condensed examples from this week’s chapter:

Decision Community Marathon Guesthouse vs Resorts
Stage / route Awareness / peripheral Preference / central
TPB weak link Attitude (“not a real runner”) Attitude (assumes a resort is better)
Frame Loss Gain
Call to action “See the beginner training plan” “Compare our rooms and rates”
Cialdini principle Social proof, commitment Authority, social proof

Whichever category your own campaign is closest to, hold your draft next to the matching worked example in the chapter before the tutorial’s build sprint.

Applying the Evidence Framework to Copy

A claim derived from documented audience research is evidence-based. A claim derived from a reasonable interpretation of that evidence is an inference. A claim representing an untested belief about the audience is an assumption.

“Our audience values flexibility above all else” is an assumption unless traceable to a documented source.
