The Rational-Emotional Marketing Test evaluates a message against the two ways people make decisions: rationally and emotionally. The rational side establishes utility, credibility, or practical fit; the emotional side creates human connection through devices such as humor, surprise, serendipity, identity, or shared celebration. Channel formats and audience behaviors will continue to change, but the underlying requirement to serve both decision processes remains stable. Teams should therefore define the rational proposition and intended emotional response separately, then examine whether the creative work delivers both without one undermining the other. The framework is especially useful for consumer brands tempted to reduce marketing to measurable functional claims. It also prevents emotional creativity from becoming disconnected from a credible product reason.

Core principles
- 01People make decisions through both rational and emotional processes
- 02New channels do not remove basic human decision mechanisms
- 03Functional proof alone leaves part of the decision unaddressed
- 04Surprise, humor, and serendipity can create human connection
How to run it
- 1
Define the rational case
State the practical reason the audience should consider, trust, or choose the offering. Make the claim specific enough to support with product evidence.
Pro tip Express the rational case in one plain sentence before writing channel copy.
Watch out A list of features is not automatically a meaningful customer reason.
- 2
Choose the emotional destination
Identify how the audience should feel during and after the interaction. Connect that emotion to the brand and the customer's situation.
Pro tip Choose a precise response such as relief, delight, belonging, curiosity, or confidence.
Watch out Generic aspirations such as 'make it emotional' give creatives no useful direction.
- 3
Design for both
Develop the message so functional truth and emotional expression reinforce one another. Use humor, surprise, serendipity, or human storytelling where suitable.
Pro tip Let the product proof become part of the emotional experience when possible.
Watch out Emotional spectacle can attract attention while obscuring why the product matters.
- 4
Translate to the channel
Adapt the execution to how people behave in the selected channel while preserving both components. Do not confuse a new format with a new decision mechanism.
Pro tip Change pacing and expression without changing the underlying proposition.
Watch out Copying the same execution across channels can weaken both comprehension and feeling.
- 5
Test the two responses
Measure whether people understood the rational proposition and whether they experienced the intended emotion. Revise whichever side is weak.
Pro tip Ask separate research questions for comprehension, credibility, recall, and emotional response.
Watch out Immediate conversion alone may not capture the long-term value of emotional salience.
In the wild
Airbnb's Icons experiences rationally demonstrate the platform's ability to offer extraordinary places while emotionally connecting fans with Barbie, Prince, and shared cultural memories.
→ The work reinforces a product truth and keeps the brand emotionally salient between infrequent travel purchases.
Common mistakes
Selling only the rational case
Functional claims can explain the offering without making it memorable or human. Define the emotional response alongside the practical proposition.
Using emotion without product truth
Entertaining creative may fail to strengthen choice if audiences cannot connect it to a credible offering. Anchor the emotion in what the product enables.
Chasing channels instead of decisions
Channels and formats change, but human choices still combine reason and emotion. Preserve the mechanism while adapting the execution.
Is it for you?
Best for
It is best for consumer brands reviewing creative work across changing channels and formats.
Not ideal for
It is not ideal for purely procedural communications where clarity, safety, or compliance must dominate emotional expression.
From the transcript
“people make decisions in two ways, emotionally and irrationally.”
“But at the end of the day, people will make a decision that's part rational and part emotional, and you have to appeal to both.”
“there's always a place for surprise and humor and serendipity and connecting with customers in a human way and getting on the emotional side of…”
