Why This Matters

1
Every day, managers try to move people: adopt a process, support a hard call, change a habit.
2
Most of us default to “explain harder” — but the research shows that’s often not what changes minds.
3
This course gives you the actual mechanics of influence — and a clear line between persuasion and manipulation.

MODULE 1

How People Actually Change Their Minds

Source: Ch. 7 — Attitudes and Attitude Change

4

The Elaboration Likelihood Model

Two different routes to changing someone’s mind

CENTRAL ROUTE
  • Careful evaluation of the actual arguments.
  • Produces stronger, more durable attitude change.
  • Requires the audience to have both motivation and ability to engage.
  • Best for: high-stakes, technical, or long-term decisions.
PERIPHERAL ROUTE
  • Reliance on cues: credibility, likability, confidence, social proof.
  • Faster, but more easily reversed by a counter-message.
  • Dominates when the audience is busy, distracted, or disengaged.
  • Best for: low-stakes asks, time-pressed audiences.
5
EXERCISE • 15 MIN

Route-Match Exercise

1
Describe your real workplace influence scenario to your partner (from pre-work).
2
Assess the audience’s motivation (do they care?) and ability (do they have time/expertise?).
3
Decide together: does this call for a central-route or peripheral-route approach?
4
Report one example back to the full group.
6

KEY TAKEAWAY

Match the route to the audience: careful arguments only change minds when people are willing and able to engage with them. Otherwise, credibility and delivery are the message.

MODULE 2

Getting Buy-In Without Coercion

Source: Ch. 6 — Cognitive Dissonance & the Justification of Effort

8

Effort Creates Belief — Not the Other Way Around

1
Cognitive dissonance
People feel discomfort when actions and beliefs conflict — and resolve it by shifting beliefs to match what they’ve already done.
2
Justification of effort
The more effort or discomfort someone voluntarily invests, the more they come to value the outcome.
3
Counterattitudinal behavior
Freely choosing a small action against your current attitude tends to shift the attitude toward the action.

Practical translation: don’t just argue that a change is good — get people to choose and do something related to it, even in a small way.

9
CASE STUDY • 20 MIN

Design the Rollout

1
In groups of 3–4, review a case: rolling out an unpopular but necessary policy.
2
Redesign the rollout to include a moment of free choice and invested effort.
3
Flag one place your redesign could tip into manufactured or fake “choice.”
10

KEY TAKEAWAY

People believe in what they’ve invested effort and free choice into — not necessarily in what they’ve been told. Real (even small) choice beats a better argument.

11

MODULE 3

Informational vs. Normative Influence

Source: Ch. 8 — Conformity and Obedience (Asch studies)

12

Two Reasons People Go Along With the Group

INFORMATIONAL INFLUENCE

“I genuinely believe the group knows something I don’t.”

Strongest under ambiguity, crisis, or when others are experts.

NORMATIVE INFLUENCE

“I don’t want to be the odd one out.”

Asch’s line studies: ~1 in 3 people conformed to an obviously wrong answer at least once.

A single dissenting ally sharply reduces normative conformity. Silence in a meeting is not agreement.

13
ROLEPLAY • 20 MIN

The Silent Room

1
Facilitator presents a deliberately weak plan; group votes agree/disagree by show of hands.
2
Same question is asked anonymously in small groups on index cards.
3
Compare results — discuss why the anonymous version usually shows more disagreement.
14

KEY TAKEAWAY

Public silence is not private agreement. If your meetings only reward agreement, you are only hearing from people willing to risk standing out.

15

MODULE 4

Ethical Lines: Reactance & Minority Influence

Source: Ch. 7 & 8 — Reactance Theory; Minority Influence

16

Where Influence Ends and Pressure Begins

1
Reactance theory
When people feel their freedom to choose is threatened, they often move away from the desired position — sometimes just to reassert control.
2
Minority influence
A small, consistent, confident voice can shift majority opinion over time — even without formal authority.
3
The ethical line
Legitimate influence adds real choice, information, or opportunity. Manipulation removes or disguises it.
17
DISCUSSION • 20 MIN

Line-Drawing: Influence or Coercion?

1
Review 4–5 short workplace scenarios (deadline reminders, calls for volunteers, etc.).
2
Sort each as “legitimate influence,” “borderline,” or “coercive.”
3
Share out and calibrate as a group — disagreement is expected and useful.
18

KEY TAKEAWAY

Real influence expands someone’s sense of choice; manipulation and hard pressure shrink it — and shrinking it usually backfires.

19

Your Action Plan

Return to your pre-work scenario and answer:

Which route (central or peripheral) fits my audience — and what will I change about delivery?
Where can I build in real choice or effort instead of just re-explaining my rationale?
How will I surface honest disagreement before I finalize this decision?
Is there any part of my approach that could trigger reactance? What will I do instead?
20

Influence expands choice.

Manipulation shrinks it. Lead accordingly.
