MKTG90003 Chap.4 Public Segmentation and Influence
Public Segmentation and Influence
Situational Theory of Publics distinguishes latent, aware and active publics through recognition, involvement and perceived constraints. Influence theories then explain how opinion leaders and networks carry interpretation between organisations, media and publics. This chapter shows how to diagnose readiness from behaviour, choose credible intermediaries and design the next reachable step without mistaking exposure for action.

Use trusted intermediaries for a reporting service
- 1Diagnose that exposure may not be the main barrier and identify confidence or process understanding as research questions.
- 1Recognise building managers and committee members as trusted intermediaries with contextual access.
- 1Provide verified steps, response standards and a two-way feedback route rather than a promotional script.
- 1Keep direct organisational information available for accuracy and accountability.
- 1Measure completed reports, recurring questions and resolution confidence rather than intermediary reach alone.
Key terms
- Latent public
- A latent public shares a consequence but has low recognition or involvement in the issue.
- Aware public
- An aware public recognises that a problem exists but has not organised to act.
- Active public
- An active public sees an issue as relevant and seeks information, communicates or acts.
- Constraint recognition
- Constraint recognition is the extent to which people believe barriers limit meaningful action.
- Opinion leader
- An opinion leader interprets information for others through credibility and network relationships.
Public Segmentation and Influence FAQ
How do latent, aware and active publics differ?
Latent publics share a consequence but may not recognise or care about it. Aware publics recognise the problem but have not organised. Active publics perceive relevance and participate in communication or action. Use case behaviour and perceptions to support the classification.
What moves a public toward activity?
Higher problem recognition and involvement, combined with lower perceived constraints, make information seeking and participation more likely. A triggering event or credible intermediary can change readiness, but structural barriers may still need operational correction rather than more messaging.
Why can a small intermediary be more useful than a famous creator?
Influence depends on credibility for the issue, audience overlap, network position, explanatory ability and feedback. A local trusted person may answer practical questions and return concerns to the organisation. Large reach without trust or service response may only spread disappointment faster.
How should segmentation change the actual strategy?
A useful segment predicts a different barrier, influence route or response; it is not merely a more detailed description of the same audience. Start with issue state. Latent publics face a consequence without recognising it, aware publics recognise the issue, and active publics communicate or organise. Then examine involvement, information seeking, constraints, readiness, trust and media behaviour.
Do not infer these qualities from age or postcode alone. Choose criteria that explain why people respond differently and that can be observed or researched. Next identify the starting state and the next feasible state. One group may need problem recognition, another may need a trial, and another may be ready to advocate. Match the tactic and indicator to that movement.
Reach cannot prove adoption, and registration cannot prove continued use. Where influence matters, distinguish opinion leaders, formal gatekeepers, peers and credible intermediaries. Explain why the selected source is trusted for this issue and whether the route creates access or merely visibility.
Treat non-participation carefully: silence can reflect low recognition, weak involvement, fear, inaccessible channels or practical constraints. Test the explanation before escalating message volume. Finally, consider how the segment can move or split as circumstances change. State the evidence that would trigger a revised strategy.
In timed work, present five linked elements: segment definition, diagnosed barrier, influence route, intended next action and matching measure. If two segments receive identical recommendations, the segmentation probably has not earned its place.
Exam move
For each practice scenario, write three columns labelled recognition, involvement and constraints. Place every case fact into one column before choosing a public state. Then write the next reachable communication or operational step. For influence questions, compare two possible intermediaries on issue credibility, audience access, explanation and feedback. Avoid deciding from follower count.
Add a measure for movement to the next stage, such as correct understanding, trial or completed use. During revision, challenge your own diagnosis: silence can reflect low recognition, low involvement, high constraints or poor access. Naming the alternative explanation and evidence needed will make the answer more credible and prevent automatic awareness campaigns.
