PSYCHOLOGY PLAYBOOK

The mental models behind ads that change behavior.

by Brian McCreadie

Advertising is about people. Platforms, targeting, and trends change. People evolve, but it’s a slow moving barge that happens over centuries through outlier mutations and natural selection, making the general population’s base psychology reliably locked in during our lifetimes.

Psychology is the foundation of every effective ad because it speaks directly to how people actually make decisions. These concepts are evergreen amplifiers. Losing ads usually fail when they push against the grain or don't tap into human behavior. Winning ads align with how our brains naturally decide what to notice, what to care about, what to trust, and what to do next.

When you use psychology as an amplifier, you’re pulling on levers that have guided human decision-making for centuries. Psych concepts are also helpful for selling in ideas to managers, clients, team members, and for reporting on why certain ads worked over others. Recommendations backed with psychology are inherently more trustworthy, because they’re built off of decades of observable proof and backing from PHDs much smarter than you and me.

This stuff can create massive unlocks in your ad creative performance, and its application is a big differentiator between beginner and advanced creative strategists.

The field of psychology is a bottomless well of concepts, many of which overlap and iterate on each other. My goal with this playbook is to point you to the most important areas and provide frameworks for easily understanding and applying them without drowning in the well!

Let’s start with the root of psychology. The human brain.

**The Brain The brain has two systems. The subconscious mind and the conscious mind.

System 1, the subconscious mind, moves very fast. It’s irrational, emotional, and reacts to its environment and past experiences for automatic, quick, intuitive and effortless decision making. It accounts for up to 95% of brain activity.

The brain as an organ is allotted 20% of the energy that the body consumes, despite being just 2% of its total weight. Since the brain is such an energy zapper, it’s wired to conserve energy by pushing attention towards the subconscious mind as much as possible and filling it with shortcuts to make it as smooth and efficient as possible.

System 2, the conscious mind, is slow. It’s the remaining 5% of brain activity and it’s deliberate, rational, careful, and effortful. This is the part of the mind that steps in when you’re weighing tradeoffs, checking for red flags, or solving tough problems. It takes energy and focus to use, which is why the brain defaults to System 1 whenever it can.

The two systems work together. The subconscious fires impulses, like the gut “I want this” reaction, while the conscious mind acts as the gatekeeper. It looks for reasons not to act, filtering decisions before they turn into behavior. Objections, skepticism, and hesitation live in the conscious brain, and if they aren’t resolved, they stall or kill momentum even when desire is strong.

Another way to think about it is that the subconscious is child-like, full of wants and impulses, while the conscious mind is parent-like, stepping in to ask “Is this safe? Is this wise?” Ads need to know how to poke the inner-child while also reassuring the outer-parent.

**Decision Making Every ad has to hit (hook attention), stick (hold attention), and score (change behavior). But before behavior can change, a decision has to be made. Deciding is the prerequisite to doing. If someone hasn’t made the decision in their mind, no prompt, CTA, or offer will move them.

Inside the brain, decision-making is a collaboration between these two systems. We need to build the impulses to make a decision to act (system 1), and break the resistance that would decide against moving forward (system 2)

This is our framework for decision making. We need to build impulse and break resistance.

Think of it as a tug-of-war. The subconscious says “I want this,” and the conscious says “Do I really? Is it safe? Is it smart?”

Building Impulses happens through heuristics, the shortcuts the brain uses to make decisions quickly. *

*Breaking Resistance happens through tackling objections, the conscious checks that filter out risk and skepticism.

Together, heuristics and tackling objections bridge the gap between lofty concepts and actual tactics. They give you levers you can pull to build desire in the subconscious and remove barriers in the conscious, turning attention into decisions.

Let’s cover these!

**Heuristics That Build Impulses

**Scarcity & Urgency **If it’s almost gone, it must be valuable.

Scarcity & urgency taps into the fear of missing out. Scarcity implies that the demand of the product is high (signally value) and urgency compresses the decision window lighting a fire to act quickly before more conscious filtering can take place. Examples here include ads that highlight limited stalk or include time-sensitive offers.

This shortcut is deeply rooted in evolution. When resources were scarce, hesitation could mean going hungry. That wiring remains. When something feels rare or limited, the impulse is to secure it immediately.

In advertising, scarcity can be communicated in multiple ways:

Urgency works by compressing the timeline for action. Countdowns, flash sales, or one-time drops light a fire under System 1, which defaults to “act now or regret later.”

These tactics are strongest when they feel authentic. Audiences can sniff out fake countdown timers or fake “low stock” alerts, which backfire by triggering skepticism in the conscious brain. Real scarcity, such as seasonal availability or genuinely limited drops, drives the impulse to act now rather than later.

Pairing scarcity and urgency multiplies the effect. A product that is both limited in quantity and available for a short time creates a double bind, meaning the brain perceives two threats at once, which pushes action even faster.

Scarcity and urgency work best in performance ads where immediacy is the goal. They are less effective for long-term brand building, where constant pressure can fatigue the audience. Used strategically, though, they are some of the strongest subconscious levers for sparking quick conversions.

**Social Proof **If other people like it, it must be good.

Humans look to the crowd for cues on what is safe and valuable, which makes social proof a way of building trust without doing research. In ads, this shows up through reviews, testimonials, and proof of popularity. Seeing “10,000+ sold” or a wall of testimonials signals safety in numbers and reduces hesitation. Ads that show a real person using and loving the product make the proof feel authentic, and the bigger the scale of your social proof, the stronger the effect. B-roll mashup frameworks that feature multiple customers are another way of bringing social proof scale into your ads.

The bandwagon effect is another concept that builds on social proof by emphasizing who approves, not just how many. Aspirational groups make audiences want to join in because they signal status or lifestyle upgrades. Associative groups reinforce shared values and identity, making the product feel like a natural fit. Dissociative groups provide contrast by showing who doesn’t use the product, letting audiences align themselves with the right side of the divide. Ads that highlight these group dynamics tap into deeper psychological drives.

**Liking **If I like them, I’ll want it.

We are more easily persuaded by people we find relatable, likable, or aspirational. In creative, this is why UGC works. A friendly creator talking casually to the camera feels like advice from someone you know, on the other end of the spectrum from a pitch from a brand. Attractive people, charismatic influencers, and creators who embody the lifestyle your audience wants to emulate all build this effect. Partnership ads work especially well here because co-branded creative with influencers or other brands borrows their likability and transfers it to your product.

Liking works with other associations as well. If a brand taps into something the audience already enjoys, that interest can carry over. For example, if Dr. Squatch releases a co-branded soap with the Minecraft movie, they will naturally convert more fans who like the Minecraft movie. It’s good to tap into broad cultural “likes” here so that the association has scale.

**Authority **If the expert says it’s good, it must be true.

Ads from the perspective of an authority figures allows your audience to turn their brain off. It communicates that other people have put lot of effort into developing experience and thinking, so they don’t have to
Authority endorsements reduce the risk of being wrong. In ads, this can look like “dermatologist tested,” expert reviews, awards, pro endorsements, or ads from the perspective of an authoritative figure (like a doctor). Authority is a slow build that happens over time, so a good fast track (especially important for newer brands) is to borrow authority through partnering with credible figures.

Independent publishers or affiliate reviewers are a strong source of authority building, and a tactic to consider is using white-labelled pages to run ads from the POV of an unbiased affiliate reviewer. Language might look like “Top 5 shower heads”, with your product placed in the top spot.

Certifications badges and “In-the-news” callouts, like showing what publications or TV shows you’ve been featured on, are also smart tactics here.

**Fluency ** If it’s easy to understand, it must be true.

The conscious brain resists when something feels confusing, overwhelming, or hard to process. Complexity raises cognitive load, which makes the decision feel riskier than it may actually be. In evolutionary terms, confusion signals that “something is hiding,” which makes the brain cautious and reluctant to move forward. Complexity raises cognitive load, which makes the decision feel riskier than it may actually be. The psychology term for this concept is processing fluency.

In ads, this means stripping out jargon, long explanations, cluttered layouts, and opting for clear and familiar language. If there’s too much text to read, or it isn’t easy to understand, your viewer will scroll!

Visual fluency matters too. White space, clean product shots, and simple graphics signal professionalism and reduce the effort required to “get it.” Often the key to strong visual fluency is removing distractions and stripping away less important elements. The more complicated the concept, the more an easy to understand visual is necessary

Metaphors are another powerful tool here. They take jargon-heavy or abstract ideas and connect them to something personal and easy to grasp. Saying “your gut is your second brain” or “this sunscreen is like a shield for your skin” frames the product in familiar terms that make the value instantly clear.

A smart strategy here is to look at the language and references your customers are using in reviews and feedback, or wherever else your customer’s voice is represented, and bring those specifics into your copy.

**Mimicry **If you show me what you do, I’ll copy it

Humans are natural imitators. Our brains are wired with mirror neurons that fire when we watch someone perform an action, creating the same impulse in us to do it ourselves. This happens automatically, without conscious thought. It is the reason we yawn when others yawn or crave food when someone eats in front of us.

In advertising, this shortcut is activated by showing the customer exactly what you want them to do. Demonstrations, tutorials, unboxings, and “watch me use it” style content are effective because the brain is not just observing, it is mentally rehearsing the behavior.

Examples include:

The subconscious prefers clear, easy-to-copy actions. If the demonstration feels too complex or confusing, the effect is weakened and may drift into the “too complicated” objection space. The key is simplicity. “Three steps,” “two ingredients,” or “one button press” makes mimicry more powerful.

Mimicry is strongest when the audience already identifies with the demonstrator. If the person feels relatable, aspirational, or likable, the subconscious is even more eager to copy. That is why creator-led UGC often outperforms brand-only demonstrations.

**Immediate Gratification **I want it now.

The subconscious brain discounts future rewards in favor of instant payoff. Ads that highlight fast shipping, instant downloads, or quick results leverage this shortcut. Even small promises like “see results in 7 days” will pull decisions forward because immediacy feels better than delay.

This effect goes beyond messaging and into operations. Speed should be baked into the entire experience. Quick communication, fast lead follow-up, and easy scheduling all make people feel rewarded instantly. Being the first and fastest option drives conversions.

Another way to tap this is by dripping wins along the way. Instead of delivering one big result at the end, break the experience into smaller milestones with daily updates or quick wins. Seven small victories often feel better and a smaller, but faster outcome should be messaged in your ads over slower & bigger.

**Reciprocity **If their free stuff is valuable, their paid stuff is too.

Social contracts drive us to reciprocate when someone gives first. Ads that lead with free value such as free trials, bonus gifts, or educational content plant this seed. For example, a free workout plan or sample pack creates goodwill that makes the eventual paid purchase feel fair and natural.

This is the fuel behind lead magnets (freebies in exchange for contact info). It’s also a popular tactic in organic social (like YouTube videos that educate) and email nurturing (providing value pre & post-purchase to make conversion rates higher when you push for purchases).

Gary Vee wrote a book about this called “Jab, Jab, Jab, Right”, with the overall premise being that providing free value (jabs) builds up good will that makes your “ask” more effective when you go for the sale (right hooks).

**Identity **Help me be more of who I am or who I want to me **If the self is who you are today, your ideal self is the person you aspire to be, a symbolic version of yourself that embodies your desired qualities, values, goals, and dreams. It represents the positive potential and highest form of who you want to become, serving as a guiding image for personal growth and development.

Identity-fueled ads can tap into who someone already is, like “If you filter your drinking water, extend that same care and filter your shower water.” They can elevate people into an aspirational version of themselves, like “Be a hero to your kids.” Or they can promise transformation, like “From an embarrassing open mic comic to headlining big shows.” Showing people who they are or who they want to become, and positioning your product or services as the bridge to get there, is a powerful motivator that can bypass the conscious mind’s filtering processes.

**Emotions **When the heart says yes, the head follows.

**Humans tie experiences to emotions, and use pattern recognition that links certain emotions to outcomes, and the brain reads those emotions as fast go or no-go signals. Emotional and logical thinking are on opposite spectrums, and many of the heuristics that fall under subconscious thinking are delivered through emotion.

Storytelling is a powerful emotion builder.

And because emotions are often delivered through stories, like the “Hero’s Journey”, and best delivered through video. Image ads usually don’t have enough real estate to effectively transmit an emotional story, plus they lack tone of voice, pacing, non-verbal communication and other elements that help the emotional delivery land. Attempting to tell emotional stories through image ads is a Medium Misfit that we cover in the Pitfalls Playbook.

Common emotions used in ads include humor, awe, fear, aspiration, pride, and sadness, each one giving the subconscious a fast jolt of feeling that primes people to convert.

**Anchoring **If the first option is high, the next one must be a deal.

Anchoring shapes value perception through reference points. When people see a higher original price before the discount, the sale price feels like a better deal. The first number someone sees sticks and colors everything that comes after.

Anchoring also applies beyond price. A premium option, sometimes called a decoy tier, makes the core offer feel smarter and more affordable by comparison. Time can work as an anchor too. If someone expects results in months, showing that your product delivers in 7 days makes it feel fast.

Quantity anchors work the same way. A supplement framed as 90 servings feels generous compared to 30. Even outcomes can be anchored. Highlighting a big aspirational result first makes smaller wins feel valuable too. Anchoring is all about setting the first expectation, then letting your main offer feel easier, faster, cheaper, or better by contrast.

**Mere Exposure ***What is familiar feels true * **Repetition builds familiarity, and familiarity feels like truth. When people see heuristics like social proof, scarcity, or emotional stories repeated across ads, the effect compounds. The story feels truer, the proof feels stronger, and the urgency feels more credible simply because it has been encountered more than once.

Psychologists have found that people rarely remember something on the first pass. Memory strengthens through repeated exposure, which is why most people need to encounter new information several times, often three or more, before it sticks. This same principle also applies to belief formation. The more often a fact or opinion is heard, the more familiar it feels, and that familiarity makes it seem true. It is why echo chambers are so powerful, for better or worse.

For brands, this means tapping into messaging your audience has already been exposed to and balancing creative diversity with keeping a consistent through-line. Different ad formats, voices, or story angles can all reinforce the same core message. High frequency across multiple creatives creates recognition, and recognition creates trust.

People also become friends by spending time together and growing familiar with one another. The same effect applies in advertising. If you feature a recurring spokesperson, or even the brand’s founder, as a throughline in your creative, mere exposure can make audiences feel like they know and like that person more over time.

**Negativity Bias **If it might hurt me, I can’t ignore it.

The subconscious is wired to pay more attention to threats than positives. Ads that start with pain points and explore nightmare scenarios grab attention fast for this reason. Highlighting what someone stands to lose if they don’t act often works better than only showing what they gain.

This is rooted in evolution. Missing an opportunity might cost you a meal, but missing a threat could cost you your life. That wiring carries over into modern decision-making, which is why negative headlines, warnings, or problem-first messaging naturally capture attention. In advertising, starting with the problem makes the eventual solution feel more urgent and necessary.

A financial app might highlight the cost of overdraft fees before offering a budgeting tool. A skincare brand might show the long-term damage of neglecting sunscreen before presenting its product. By framing the problem sharply, the solution feels like relief.

Brand teams often build brands around positivity and happy feelings, going in the opposite direction of this heuristic. That approach can work for long-term brand building, but performance ads often need to lean into pain points and risks to capture attention and sell emotionally. It is important to distinguish between ads made to build brand and ads made to drive performance. The Performance vs. Brand Misfit is another topic we cover in the Pitfalls Playbook.

**Progress **If I’m almost done, I should finish it.

Progress creates momentum, and being close to the goal triggers the motivation to hit it. Ads that highlight steps, or check points, and imply that you are making progress makes you compelled to continue trekking along the journey.

This is also known as the goal gradient effect. The closer people feel to a finish line, the harder they push to get there. Loyalty punch cards that start with two stamps already filled are redeemed more often than blank ones, simply because people feel they are already in motion. The same applies in digital funnels. Showing that someone is “80% complete” with a sign-up or “almost at free shipping” nudges them to take the final step.

In ad creative, this can be leveraged through messaging how your customer is already making progress towards completing their goal. Open loops are another. When a story or message begins but does not immediately resolve, the brain leans in to close the gap. Ads that use curiosity bait, like a vague hook that says “THIS might ruin your wedding day” or a completion bait like “you won’t believe what I looked like after” with the results at the end of the video, create a tension that people want to resolve. Progress bias and open loops work together because both thrive on incompleteness. Once the journey starts, people want to finish it.

**Framing ***It’s not what you say, it’s how you say it. * **The way something is presented changes how people perceive it, even if the facts stay the same. People rarely evaluate numbers or outcomes objectively. They lean on the frame around the information to decide whether something feels positive or negative, cheap or expensive, safe or risky.

Framing price is one of the most common uses. A subscription framed as “less than a cup of coffee a day” feels more affordable than “$30 a month,” even though the numbers are identical. $19.95 feels cheaper than $20.00, even though the difference is only five cents, because the frame puts the price in the teens instead of the twenties. The same principle applies to usage. A bottle described as “lasting three months with daily use” feels more generous than “90 servings,” even though both mean the same thing. “30% off” sounds more grandiose than “$5 off”.

**Objections that need Resistance Breaking Okay, we just covered the subconscious brain half of the equation with a big list of heuristics that drive customers toward making impulsive decisions based on mental shortcuts. Stack these concepts. The stronger the subconscious impulse, the harder it is for the conscious brain to contest it.

When impulses run high, especially for lower-ticket products, sometimes that alone is enough to drive the decision. But as price, risk, or commitment increases, or if red flags fire, the conscious brain starts speaking louder. This is where the second half of the equation comes in.

The subconscious side gives us universal shortcuts we can assume apply to most people. The resistance-breaking side works differently. It has to be anchored in the real, specific objections your audience raises. Breaking resistance tactics need to be in reaction to the specific objections that our audience is raising to the surface. You identify objections, trace them back to the root, and then counter them with proof, trust builders, and direct tacklers.

Let’s walk through a step-by-step framework for breaking resistance:

  1. **Identify the objections
  2. **Prioritize which objections matter
  3. **Dig into the root
  4. **Insert specific and trustworthy resistance breakers

**1. Identify the Objections

The first step in breaking resistance is learning to listen. Real objections come directly your audience and your customers. You can find them in the comments on your ads, in customer reviews, in transcripts from support calls, in conversations with your sales team, YouTube videos and blogs within your niche, and other channels where your audience is sharing feedback.

You should prioritize identifying objections that are specific to your products or services, but you can also expand your search by looking at objections raised at your competitors.. If you study what people complain about when using other brands, you will uncover the fears and frustrations that are baked into the category. These are objections waiting to appear in your funnel unless you address them head on.

At this stage you should not try to solve or argue with the objections. Your job is simply to capture them. Build a running log of the exact phrases people use. Think of this like collecting clay before you start sculpting. We have a full breakdown of research exercises to walk through in our Customer Research Playbook.

**2. Prioritize Which Objections Matter

Not every objection deserves your attention, and some objections are more dire to tackle than others.

Look out for disqualifiers. If you sell supplements and someone says “I don’t take pills,” that is not resistance you need to overcome. There are plenty of people who do, so it’s a smarter use of your time here to point your attention to other pockets of your audience.

Another group of objections are edge cases. These are highly specific personal preferences or unusual situations that do not represent the broader market. “I only use products made in my hometown” is an example. If you try to solve every edge case, you dilute your message and weaken your impact with the majority who actually matter.

If objections that represent a disqualified audience appear in public forums, like comment sections on your ads, consider responding with a comment that doubles down on your positioning. Responding to “I don’t take pills” with “Our product is designed for people who want a quick, easy daily pill. If that’s not you, no problem!”, sends a clear signal to the right audience and strengthens their alignment with the product.

The objections you should prioritize are the ones that signal desire mixed with hesitation. Look for friction rather than a brick wall. These are the people who want what you offer but are not yet convinced to take the leap.

**3. Dig Into the Root

As you find your customers objections, you’ll discover that some objections, like “it doesn’t whiten coffee stained teeth” are straight forward enough to be tackled at the surface level. But other, vague objections like “it’s too expensive”, have a surface level and a root level. A price objection is rarely about the actual number. It is usually about perceived value. A trust objection is rarely about the product itself. It is often about whether the brand or messenger feels credible.

If you only take these objections at face value, you risk patching the wrong hole, so you need to keep digging until you uncover the root. A good way to do this is by using the “five whys” method. Start with the surface objection and ask “why” until you arrive at the deeper cause. “It’s too expensive.” Why? “Because $50 feels like a lot.” Why? “Because I am not sure it will work.” Why? “Because I have not seen proof.” The root is not cost, it is a lack of proof that there will be a proper value exchange.

Objections commonly reveal that the customer needs a specific type of education or more trust, and digging into roots can help map your objections to the type of education and trustbuilding that is needed.

**4. Insert Specific Objection Tacklers

Once you have your surface level and/or root level objections identified, the next step is to create objection tacklers that directly address those concerns. These objections are often rooted in the customer needing more education and more trust, so tackle these in one swing with specific education that is trustworthy.

If you discover a teeth whitening product injection that says it “doesn’t work on coffee teeth”, and the product does, they need specific education that is trustworthy. Messaging like “our study tracked 1,327 participants over 12 weeks” will be more effective than messaging without hard facts like that. We have a playbook called the Building Trust Playbook that dives into trust builders and trust breakers in detail. Lean into the builders and avoid the breakers!

**Tactics to make objecting tackling more effective **Belief Re-Ranking Resistance breaking is often an attempt to change someone’s belief, however beliefs are sticky. People protect beliefs because they are tied to identity and worldview, and when you push too hard against a belief, the conscious brain digs in its heels and resists even harder.

A smarter approach is not to change beliefs, but to re-rank them. People already juggle multiple beliefs at once, and not all beliefs carry equal weight in a decision. Re-ranking means reorganizing what they already believe so that a supporting belief rises in priority and the objection falls lower on the scale.

This is especially powerful because objections often come from beliefs that are technically true but not always decisive. For example, someone might believe “it’s too expensive.” That belief does not need to be erased. Instead, you downgrade it by claiming “It’s expensive, but peace of mind makes it worth it.” The belief in price still exists, but it no longer controls the decision.

With this, you are not asking them to reject something they feel is true. You are showing them a way to reorganize their truths so that the path to purchase feels aligned and logical. They stay internally consistent while still giving themselves permission to act.

Example:

💰 **Objection: It’s too expensive ** ✘ “We’re cheaper than competitors.”
✔ “Yes, it costs more. But it lasts twice as long and saves you money every year.”

**Gradualization **Another technique for breaking resistance is gradualization. Where belief re-ranking reorganizes what someone already holds to be true, gradualization reduces the size of the leap you are asking them to make. People resist big, sudden shifts because identity, habits, and routines feel under attack when change is framed as too extreme. In ads, this means avoiding all-or-nothing messaging and instead positioning the product as an easy first step.

Gradualization in creative shows up through trial offers, starter packs, and small habit changes. A supplement brand might say “try one scoop in your morning coffee” rather than “change your entire health routine.” A fitness app might suggest “just 5 minutes a day” instead of demanding an adherence to a full workout plan. Each micro-shift lowers the barrier to action, and once people commit to the first step, the path to bigger commitments feels natural and self-driven.

This also overlaps with the progress heuristic, where accomplishing the first step compels you to continue on the journey.

**New Mechanisms **A new mechanism is a new unique angle that makes a product feel like a fresh solution. Heavy resistance often shows up in two scenarios: when people have had negative experiences with your type of solution in the past, or when the market is crowded with similar promises that all blur together. In both cases, repeating the same claims only deepens skepticism. A new mechanism resets that resistance by positioning the product around something novel, giving the audience new hope that this is not just another version of what already let them down.

One of the most famous examples comes from Lucky Strike in 1917. Their cigarettes already went through a toasting step, as did nearly every cigarette on the market. But Lucky Strike took this ordinary part of production and rebranded their product as “Toasted Cigarettes”. This re-branding turned a standard process into a fresh story that inspired curiosity and created a perceived difference where none really existed. Other modern examples include a skincare brand calling hyaluronic acid “water magnet technology,” or a supplement company framing probiotics as “gut defense shields.” The branding here transforms a feature into a mechanism that sparks interest, inspires new hope, and sidesteps the resistance that they’ve built up through past experiences with failed solutions and already formed beliefs.

A note here is that the outcome you provide should always be crystal clear to your audiences. Relating to the fluency heuristic, if your outcome is too confusing then your viewer is unlikely to take action. New mechanisms are rebranding the “how” an outcome is delivered, and in this instance it can be effective to brand your new mechanism with a term that incites curiosity, like with the “water magnet technology” example above.

This connects directly to the concept of market sophistication, which we’ll cover in the Copywriting & Ad Structure playbook. As markets mature, messaging becomes saturated which creates more of a need to standout. Introducing a new mechanism is a good way to do this.

From Decisions to Action: The Fogg Behavior Model

So far we have focused on how people make decisions inside the brain, weighing impulses against resistance until the conscious gatekeeper allows a choice to move forward. But a decision alone does not equal behavior. Deciding “yes” in the mind still needs to translate into clicking, signing up, or buying. This is where the next layer comes in: driving action.

One of the most useful and famous models for understanding behavior change is the Fogg Behavior Model. It states that behavior happens when three elements converge at the same moment: Motivation, Ability, and Prompt. If any of these are missing, action will not occur. A person may be motivated but unable, or able but unprompted, or prompted but unmotivated.

The equation is: Behavior = Motivation + Ability + Prompt

**Motivation

Motivation is the desire that fuels action, and it’s typically expressed through rewards and punishments. I like calling these carrots and sticks, two ways to make a donkey move in the direction you want it to move.

Carrots are the positive outcomes people want, like saving money or gaining confidence, while sticks are the negatives they want to avoid, like embarrassment, pain, or wasted time. The strongest ads take functional desires, such as whiter teeth or cheaper bills, and connect them to aspirational drivers like confidence, safety, or love. These aspiration drivers tie to the “Life Force 8” primal desires that we will explore in more detail shortly. Motivation is powerful but fleeting, so the role of creative is to spark it, amplify it, and capture it before it fades.

**Ability Ability is the measure of how easy or hard it feels to take action, and the easier something feels, the more likely people are to do it. Even if motivation is high, action stalls when the task feels confusing, time-consuming, expensive, or outside of routine. Advertising that drives behavior lowers the friction by making the next step feel simple and attainable, whether that is a one-click checkout, a short form, or a clear path that removes unnecessary effort. When people believe they can do something with little time, money, or brainpower, ability becomes high and behavior is much more likely to happen.

**Prompt A prompt is the spark that tells someone to act now. Without it, motivation and ability never translate into behavior. Ads are examples of these prompts, but really they are any touch point between a brand and a potential customer.

**Carrots & Sticks Alex Hormozi, a business educator, has a framework that directly ladders up to the Fogg Behavior model called The Value Equation.

The value equation is: Value = (Dream Outcome × Perceived Likelihood of Achievement​) / (Time Delay × Effort and Sacrifice)

He’s stating that value is maximized when desire and perceived likelihood of achievement is high, and when time delay and effort and sacrifice is low.

In other words, people determine value based on how big the promised reward is, how likely they believe they are to achieve it, how quickly they can get results, and how much effort is required. This equation heavily overlaps with everything we’ve already mentioned, but it’s a helpful checklist for translating the previous concepts into value-driven messaging.

I teased this earlier, but I like to break the value equation down into two categories of messaging: Carrot Messaging (Incentives) and Stick Messaging (Punishments). Two ways to get a donkey to move in the direction you want. Essentially positive angles and negative angles. The Carrot represents the compelling, positive outcomes that make someone want to take action, while the Stick emphasizes the pain and consequences of inaction, pushing them away from their current situation.

If people have too many carrots, more carrots won’t be motivating. They need their carrots taken away, or they need more stick. You should test carrot messaging, stick messaging, and a mix of both to see what performs best with your audience. Humans have a negative balance, buit it’s also important to understand how pain fades, but the memory of reward lingers. Think of being hungover. People forget the discomfort of the hangover when chasing the remembered pleasure that comes with going out.

Here’s a breakdown of the Value Equation viewed through the carrot & stick lens.

**Carrot **Carrot messaging is about making the potential reward so irresistible that the customer feels excited to move forward.

**Stick **Make the pain of staying the same feel unbearable. If people don’t feel a strong reason to change, they won’t.

These are the elements that make up the value equation, but if you ladder them up to higher level concepts you’ll see that each element reflects either increasing motivation or increasing ability, the two levers that, when paired with a prompt (your ad), causes a behavior change.

**Primal Desires **The dream outcome & nightmare scenarios are particularly important parts of driving motivation. Every product or service solves a problem. The problem is why the product or service exists. The dream outcome and the nightmare scenarios explore the ends of solving or not solving the problem.

There are two types of problems: functional problems and aspirational problems.

  1. Functional problems are straightforward and easy to communicate with direct messaging. "Our soap smells amazing and doesn’t have harmful chemicals." We’re focused on the functions the product or service fulfilled, like features, benefits and the outcomes that those features and benefits bring.

  2. Aspirational problems are rooted in ideal identity and ideal lifestyle. They tap into who the customer wants to become, how they want to be seen, and what kind of life they want to live. "Be the kind of man that smells amazing, feels confident, and attracts the right people into his life." This type of messaging goes beyond the product’s utility and connects to ambition, status, and belonging.

Drew Whitman’s Ca$hvertising calls these currents the Life Force 8. These are the primal desires that shape human behavior, and they can be mapped directly into creative messaging.

The carrot should looks at fulfilling these primal desires, while the stick highlights the fear of losing them. Carrots might underline better health, more confidence, or stronger relationships, white sticks might include illness, embarrassment, or failure. Both work because they hit on the same underlying drives.

**Outro Using my darts analogy again, ads need to hit, stick, and score.

They need to hit by gaining attention, stick by holding that attention, and score by changing behavior.

Changing behavior has two parts. The first is making a decision. The second is taking action. Both parts must be won inside the mind.

Advertising is never just about media buying or creative production. At its core, it is about guiding human decision-making. Every ad is a negotiation between the subconscious and the conscious. The subconscious is fast and impulsive, pulling people toward shortcuts and emotional triggers. The conscious is slow and cautious, raising objections and scanning for risk. The tug of war between these two systems decides whether a spark of desire turns into a decision to purchase, and the Fogg’s Behavior model explains how decisions turn into actions.

The creative strategist’s job is twofold. First, map your customer’s impulses and objections. What shortcuts are most likely to spark desire? What resistances are most likely to block it? Second, translate those insights into creative execution. Build ads that make the carrot irresistible and the stick unavoidable. Then smooth every path so action feels simple, natural, and risk-free.

Psychology is the oldest tool in advertising and still the most reliable. Platforms will change. Formats will evolve. Targeting will rise and fall. Human decision-making will not. The strategist who understands how to build impulses and break resistance are the ones who will have the edge!
