Affect heuristic
Why people make decisions based on immediate emotions rather than logic, and how to use the affect heuristic in your marketing.
In this issue
Hey 👋 The Crew here.
It’s December and it’s time for all the yearly wraps to remind us of the content we consumed—Spotify wrapped, Goodreads’ Year in Books, Letterboxd Wrap…
If you spent a lot of time listening to good music, reading good books, and watching good movies, it was a year well spent.
And if you had good marketing results on top of it…

Sounds good?
Did you know that your odds of being in a plane crash are one in 13.7 million?
Meanwhile, the odds of participating in a fatal car accident are approximately one in 90 during your lifetime.
And yet, many people who are afraid of flying have total confidence in getting behind the wheel.
This is due to the affect heuristic—the mental shortcut where we make decisions based on immediate emotions rather than analytical reasoning.
Why? Well, our brain doesn’t work algorithmically. When we need to make a decision, we often do a quick “emotional temperature check” rather than a full logical analysis.
That’s why, for example, some people will choose a jumbo bran muffin over a donut without looking at the packaging—it just feels healthier.
It’s also why most people would adopt a “cute” dog over an “ugly” one without evaluating its doggy character traits—possibly ending up with a naughty, furry piece of work.
And as you undoubtedly guessed… the affect heuristic is a key element of selling. It’s the reason why most ads are focused on emotions, and not rationale.
So let’s see how you can use it right away.
Three ways to leverage affect heuristic
Associate your brand with positivity
The greatest trick Coca-Cola ever played? It convinced us that it is not an unhealthy, overly sugary drink.
And thanks to the company’s decades-long effort to make us feel positive emotions whenever we see a Coca-Cola bottle on the shelf, this drink is now associated with happiness, rather than its list of harmful ingredients.
Lesson for you: A lot of top-of-the-funnel stuff can seem like a vanity metric at times. But carefully curated branding with defined values and a strong voice will ultimately place you above competitors in due time.
Here’s an example of a small retail ad that tries to position its brand as the ethical hunting gear:

Ethical hunting? That may sound like an oxymoron to some, yeah. But it works.
Place time constraints, but emphasize your brand’s upsides
In 2000, a group of psychologists led by Melissa Finucane published a study revealing that if people are put under time pressure, they will turn to affect rather than analytical thinking.
Also, when given favorable information about an activity, participants judged it as beneficial and low-risk.
So the more positive things we know about something, the less we even tend to care about the negative—especially if there’s a limited amount of time to make a decision.
That’s why just putting limited-time offers and other time-related pressure might not be enough. There also has to be enough upside for a snap decision without second thoughts.
Nowadays, you can easily combine the two by saying the offer is limited in the copy while accompanying it with a video that highlights the benefits. Like these three:

Keep the mood upbeat
One way to always have an edge is to make people happy just by looking at your ads.
Think about which brands make you joyful—or the ones you trust. They usually sprinkle a lot of positive visual cues in their branding and messaging.
And by “visual cues,” we mean a mix of:
- Color. Calming tones like blue or green can have a trustworthy effect, while yellow or orange can elicit energy. But we’ll talk about color psychology in a separate newsletter.
- Imagery. Use images that align with their desired emotional outcomes. A happy, healthy family is usually depicted in life insurance ads, clean visuals suggest organization, and so on.
- Copy. Try to include emotionally-charged words where possible to make the most out of the affect heuristic. Stories and testimonials can also work.
Here’s a landing page for Amazon Flex—a service that allows you to deliver Amazon packages for extra cash:

Calming color. Inspired, smiling face, and a vast, scenic neighborhood in the background that amplifies the feeling of freedom.
It looks like a nice side hustle. Yet, it invites you to deliver packages for minimum wage…
And it works.

E-COMMERCE:Good news. This Black Friday saw a 5% increase in sales year-over-year, with the US alone making $17.5B—a 7% increase from last year. Also, mobile devices accounted for 55% of spending and retail site traffic from AI chatbots rose by 1800% from last year. Wow.
E-COMMERCE:Sales aren’t over. And if you’re selling to baby boomers, make sure you implement a Buy now, pay later (BNPL) feature—since 75% are planning to use it this holiday season. This especially applies to higher-income individuals… so keep that in mind.
SEARCH:Uh oh. A recent study has shown that ChatGPT search fails to cite news sources properly, often linking to plagiarized content rather than original sources. If you’re hoping to get traffic from ChatGPT, well, it sounds like it’s not yet reliable for visibility or quality control. Ugh.
BLUESKY: It’s official. Bluesky has more active website users than Threads. Granted, Threads still wins in app usage, but even that number is closing. Before November 5, Threads had five times more US users than Bluesky. Now, it’s just 1.5 times. How long before Bluesky closes the gap?
