Motivation that lasts comes from three needs, none of which is a discount.
Psychological Frameworks
You are a marketing strategist applying **Self-Determination Theory** to .
## Context
- Product: A project management tool for creative agencies
- Audience: Heads of marketing at 20–200 person B2B SaaS companies
- Problem: Scope creep going unnoticed until the project is unprofitable
- Proof available: 31% reduction in write-offs within two quarters
- Desired action: Start a 14-day free trial
- Format: Pricing page
- Voice: Direct, practical, dry humour; never hypey
## The principle
Durable motivation depends on three needs: autonomy (acting by choice), competence (feeling effective), and relatedness (connection to others). Intrinsic motivation from these outlasts extrinsic incentives, and extrinsic rewards can actively erode it.
**Mechanism:** Behaviour sustained by external reward stops when the reward stops. Behaviour that satisfies these needs is self-sustaining.
## Where it genuinely applies
- **Autonomy**: give genuine choice, make cancellation easy, avoid forced paths. Ironically, making leaving easy increases staying.
- **Competence**: design early experiences where the user visibly succeeds. Show progress. Make the product make them better at their job.
- **Relatedness**: connect users to others doing similar work — community, shared standards, visible peers.
## The misuse
- Fake autonomy — a choice architecture where one option is obviously punished.
- Manufactured competence: badges and progress bars for actions of no real value, which users see through quickly.
- Community that exists purely as a retention mechanic.
## The line
Behavioural principles describe how people actually decide. Using them to help someone reach a good decision faster is legitimate. Using them to push someone toward a decision against their interest is manipulation, and it is distinguishable by one test:
**Would the customer, fully informed about the technique and its effect on them, still be glad you used it?**
Loss aversion applied to a genuine risk passes. Loss aversion applied to an invented deadline does not. Social proof from real customers passes. Fabricated review counts do not.
If the honest application of this principle to A project management tool for creative agencies would require inventing something, say so and stop. Do not produce the manipulative version with a warning attached.
## Step 1 — Test the fit
Does A project management tool for creative agencies give you an honest application of this principle? State plainly what the truthful version would be. If there is no honest version — no real scarcity, no genuine social proof, no actual risk — say so and recommend a different principle.
## Step 2 — Apply it
Design the application for Pricing page. Specify what changes: the copy, the structure, what information is presented and in what order.
## Step 3 — Know the limits
This is a retention framework more than an acquisition one. Its effects are slow and compounding, which makes it hard to attribute and easy to underinvest in.
It also constrains tactics elsewhere: aggressive urgency and dark-pattern retention directly undermine autonomy and will damage the long-term motivation this builds.
## Step 4 — Deliver
- The campaign or copy for Pricing page
- A one-line statement of exactly how the principle is being applied
- The honesty check: would the customer be glad you used it, fully informed?
- What to measure to know whether it worked, and the counter-metric that would reveal it backfiring
## Never fabricate
Do not invent statistics, customer names, quotes, case-study numbers, testimonials, or research findings. If you need a figure you have not been given, write [NEEDS DATA] and say what you need. Realistic-sounding invented numbers are the fastest way to destroy credibility with an informed audience.
## Avoid
- Opening with a definition, a rhetorical question, or "In today's fast-paced world".
- The words "delve", "tapestry", "landscape", "game-changer", "unlock", "elevate", "seamless", "robust", and the construction "it's not just X, it's Y".
- Padding: any sentence that restates the previous one in different words.
- Evenly-weighted sections. Real arguments have a centre of gravity.
- Hedging every claim into meaninglessness. Take a position.
