In qualitative market research, getting people to express their honest thoughts can be surprisingly difficult—especially when the topic is sensitive, personal, or tied to identity. That’s where projective techniques come in. One of the most engaging and effective tools in this space is the cartoon test.
The cartoon test is exactly what it sounds like: respondents are shown simple cartoon-style images—usually featuring one or two characters in a situation—and are asked to fill in the speech or thought bubbles. It sounds playful, even childish, but it’s a remarkably effective way to access subconscious attitudes and emotional reactions.
Because the format is so familiar and non-threatening, people tend to let their guard down. They respond quickly and instinctively, projecting their own feelings or beliefs onto the characters without realizing how revealing they’re being. What they put into those bubbles can be more honest than anything they’d say in response to a direct question.
A Real-World Example: Banking and Trust
In a study exploring perceptions of banking services among young adults, researchers used cartoon tests showing a character standing at a bank counter, frowning at a teller. One bubble was filled in: “So you're telling me…” and participants were asked to complete the dialogue.
Responses included:
From these short answers, researchers learned that frustration, confusion, and distrust were the dominant emotions—more so than had been evident through traditional focus group questions. This feedback helped the bank refine both its messaging and customer support flow for younger demographics.
Consumer Goods: Everyday Truths Behind Closed Doors
A consumer goods brand exploring household cleaning habits used cartoon tests to uncover what moms and dads really thought about cleaning routines. One cartoon showed a child spilling juice on a white couch. The mother in the cartoon had an empty speech bubble, and participants were asked: “What would this mom be thinking or saying?”
Some of the answers were humorous:
Others were more telling:
What came through wasn’t just the annoyance at messes—it was the underlying emotion of being underappreciated, unsupported, and overwhelmed. That gave the brand a powerful angle to focus on empathy and shared responsibility in its next campaign.
Personal Care: Image and Insecurity
Cartoon tests have also been used effectively in personal care research, especially in categories like skincare, deodorant, and beauty products—areas where self-image and social confidence are deeply intertwined.
In one project, researchers showed teens a cartoon of a young girl getting ready for school, looking uncertainly into a mirror. Her friend stands nearby, with an open speech bubble. When asked what the friend might say, respondents wrote:
These responses opened a conversation about pressure, comparison, and the unspoken stress many teens feel about their appearance. The cartoon allowed them to voice judgments and insecurities they would never openly admit about themselves, but which were clearly part of their daily experience.
Healthcare and Social Topics: Saying the Unsaid
Cartoon tests also have value in healthcare and public awareness campaigns. In a study about mental health awareness, participants were shown a cartoon of a man sitting alone in a café with a thought bubble above his head. One participant wrote, “If I say something, they’ll think I’m weak.” Another added, “No one wants to hear my problems anyway.”
These seemingly simple comments provided raw, emotional insight into the stigma men associate with opening up. The client used this to reshape campaign messaging from “speak out” to “you’re not alone,” focusing on solidarity and silent support rather than direct emotional confrontation.
Similarly, in a campaign for smoking cessation, a cartoon showed a person hiding cigarettes in a drawer. The partner’s speech bubble was blank. Respondents filled it with lines like:
These answers were used to highlight the emotional toll that addiction can take on relationships, making the campaign more relatable and impactful.
Why It Works
Cartoon tests tap into a part of the brain that isn’t trying to “answer the right way.” The visual context is disarming. There’s no need to defend one’s answer—because it’s not “your” answer, it’s what the character might say. This makes it easier to explore emotions like embarrassment, anxiety, guilt, or even joy.
The technique also works well across literacy levels and cultures. Unlike written questionnaires or verbal interviews that depend on verbal fluency, cartoon tests invite expression in a universal format. People of different ages, backgrounds, and education levels can all engage with a drawing—and often, what they share is deeper than words alone could reach.
In Summary
Cartoon tests are a deceptively simple tool in qualitative research—but don’t be fooled by the friendly illustrations. Behind the playful format is a direct line to consumer truth. From household habits to healthcare fears, financial frustrations to teenage insecurities, this method uncovers what people might never say—but what they’re always thinking.
For brands and researchers willing to listen between the lines, cartoon tests offer a remarkably human—and surprisingly accurate—window into the hearts and minds of their audience.
