After years in conventional advertising, including senior leadership roles at agencies such as Mudra Communications, DDB India, Biju Dominic began exploring what shapes human behavior and how people make decisions.
In his recently released book, MicroStimuli: The New Science of Persuasion, published by Penguin Random House India, Dominic explores how non-conscious processes influence human decision-making, drawing on insights from neuroscience, artificial intelligence, and design.
The book details MicroStimuli — non-conscious persuasive stimuli deployed in the final second before action to activate the brain’s fastest pathways and change behavior in milliseconds. It also explores Ethnolab, a research method designed to uncover non-conscious brain processes and craft MicroStimuli, described as precision point-of-action interventions.
Dominic believes that awareness and recall alone rarely translate into purchase or sustained use, particularly in a smartphone era where attention spans are measured in seconds rather than minutes.
To learn more, we caught up with Biju Dominic to discuss the awareness-action gap, the role of Ethnolab in understanding behavior in real-world contexts, why marketers need to rethink persuasion for the smartphone era, how AI is making hyper-personalized persuasion increasingly possible, and the marketing situations where a MicroStimuli approach might be more effective than a traditional campaign.
For a marketer unfamiliar with MicroStimuli, what does adopting this approach actually look like in practice?
Marketers should free themselves from the clutches of the television medium and its 30-second ad-based persuasion model and rethink strategy for smartphones—an always-with-you, always-on medium where context duration is in seconds, if not milliseconds.
Rather than relying on rational, self-reported explanations from traditional research, uncover the vast non-conscious barriers and triggers that drive consumer behavior.
The most effective behaviour change happens at the point of action, at the decision point. Instead of mass media’s “spray and pray” approach, MicroStimuli is always deployed at the points-of-action, the place where the actual decisions are made.
The most effective behaviour change happens at the point of action, at the decision point.
With an always-on medium like a smartphone, the focus of marketing should move from e-commerce to e-consumption: triggering more consumption moments for the brand.
Measure effectiveness not by attitudinal lift or awareness, but by how well you close the brand’s awareness–action gap.
The old rule – “change attitudes to change behavior”, no longer holds. With MicroStimuli, the new rule is: change behaviors, and attitudes will follow.‘
You spent 17 years in conventional advertising before walking away from those methods. What broke the model for you?
Conventional ads build awareness, but they rarely drive action – purchase and continued use. That gap pushed me to pursue more effective persuasion strategies.
The book contends that awareness-based persuasion has a fundamental gap—people know, but don’t act. Where does that leave brand marketers who build campaigns around recall and recognition?
Many brands achieve high levels of awareness; however, such recall seldom translates directly into purchase or sustained usage. Addressing the awareness–action gap is the primary challenge for today’s brand marketers.

Ethnolab is presented as a way of understanding behavior in real-world contexts rather than relying on traditional research methods. What does it uncover that focus groups and surveys typically miss?
Ethnolab puts respondents in a decision-making mode and observes their decision-making process. Unlike the traditional research methods that focus on what people Say, Ethnolab focuses on what people Do.
Traditional research methods capture the conscious, rational explanations of consumers for their behaviours. But Etnhnolab tries to unearth the vast non-conscious barriers and triggers behind every consumer decision.
Ethnolab, a multiple ESOMAR award-winning approach, has uncovered insights even in highly personal domains, such as sexual behavior.
The book is built around real-world applications. Is there a case study that surprised you the most, and what did it reveal about how people make decisions?
The Railway Trespassing project was one of the most surprising I have worked on. What surprised most about the problem was that visibility of the incoming trains was very good, at all accident spots. The insight about the cause of the problem: the deficiency of the human brain to correctly judge the incoming speed of a large object was even a bigger surprise.
This reinforced my belief that decoding the brain’s “hidden algorithms” is essential to understanding human behavior and designing effective persuasion strategies.
The book says MicroStimuli is better suited to the smartphone era than the traditional 30-second commercial. How should that change the way brands approach creative and media strategy?
On television, viewers stay with the editorial context for 5–21 minutes. On smartphones, that window shrinks to just 3.8–7.8 seconds. With attention dropping so dramatically, brands can’t keep copy-pasting TV-era persuasion tactics onto mobile. Marketers must rethink, from the ground up, how they persuade on the smartphone.
How has AI changed what’s possible with MicroStimuli, and are there things it makes harder, not just easier?
AI has made hyper-personalised persuasion far more achievable. By leveraging the smartphone’s always-on, always-with-you presence, brands can deliver tailored stimuli not only to drive purchases but also to shape more frequent behaviours, such as creating additional consumption moments.
AI has made hyper-personalised persuasion far more achievable.
Whereas television offered relatively fixed windows for brand messaging—typically evenings when viewers were seated in their living rooms, smartphones enable outreach at any time. Still, pinpointing the digital moments that truly matter and matching each individual with the right personalised stimulus remains a challenging task that AI professionals have yet to fully master.
You describe this as “a new playbook for marketers.” As the framework moves into commercial contexts, what ethical responsibilities come with influencing behavior below conscious awareness? Are there concerns about navigating the line between persuasion and manipulation?
The choice is clear: continue building persuasion strategies on the mistaken belief that human behavior is a conscious, rational-centric process, or have the courage to discard tradition and embrace the biological reality that behavior is largely non-conscious and emotion-centric. No doubt, recognizing this true center of human behavior is, in its implications for influence, arguably more consequential than discovering that Earth is not the center of the universe.
Leveraging non-conscious brain processes to shape behavior is not manipulation; it is the responsible application of modern neuroscience to improve lives around us.

As with any invention, MicroStimulitoo can be used for positive or negative ends. Mastering the MicroStimuli framework not only enables positive change but also helps reveal—and thereby limit—the persuasive strategies of bad actors.
The book challenges the idea that awareness naturally leads to action. What are some common marketing situations where a MicroStimuli approach might be more effective than a traditional campaign?
Many decisions are made at high-risk points of action—near hazardous machinery, in dangerous natural environments, or while driving. MicroStimuli can be applied to nudge safer behaviors in these contexts.
Where the desired action is already defined but adherence lapses—for example, taking medication or brushing at night—smartphone-based, always-on, always-with-you E-Action strategies using MicroStimuli can prompt the right behaviors throughout the day.
MicroStimuli-based strategies will be most useful in places where the awareness of the brand or even the intention to buy the brand is very high. It can significantly increase Click Through Rates (CTRs) in e-commerce.
CTRs do not really lead to a final transaction. Today, the cart abandonment rate is around 70%. Appropriate MicroStimuli can play a significant role in mitigating the cart abandonment behaviour in e-commerce.
