Key takeaways
- Optimism bias makes people believe good things will happen if they buy your product, making them more likely to make a purchase.
- Focus your marketing on positive future outcomes and success stories to tap into customers’ natural hopefulness.
- Be ethical—don’t over-promise or mislead; build trust by keeping your claims realistic.
Optimism bias is the idea that good things are more likely to happen to them than bad things.
Researchers say about 80% of us have this wired in — so it’s not just you.
And it affects everything.
Relationships…
And every wild New Year’s resolution you’ve ever made.
Why else would people buy fancy gym memberships they’re done with by February?
Or jump into careers thinking they’ll rise to the top, no sweat?
It’s that voice saying, “This time will be different.”
In marketing, this could be powerful.
People are already walking around thinking things will just work out.
And when they shop, that optimism kicks in.
When they spot something claiming to make life better, they’re ready to believe it’ll deliver.
But here’s the catch: optimism bias doesn’t mean you get to go overboard with the hype.
They want to believe, sure.
But they don’t want to feel sold to.
So here’s how you can tap into optimism bias the right way — boosting sales and trust without the BS.
5 ways to make optimism bias do the hard work
#1 — Sell the dream, not your product
Want to hook people?
Show them just how much better life could be with you in the picture.
It’s like giving them a fast pass to their upgraded future.
Keep the copy tight and focused on the payoff.
“Wake up refreshed every morning.”
Or “Own your dream home without selling a kidney.”
Also, don’t skimp on the visuals.
Show people actually enjoying the perks.
A calm morning in a spotless kitchen.
Skin that’s practically glowing.
Let them see how much better their lives could be — and how you can help them get there.
Fitness brands get this strategy right all the time.
Look at Nike’s iconic “Just Do It” campaign.
They’re not just selling shoes.
The focus is on the future you — the one smashing limits and hitting personal bests.
This taps right into optimism bias, that built-in belief we all have that we’re capable of big things (if we’ve got the right gear, that is).
Even the simplest ad copy can work wonders.
By focusing on future transformations, you’re helping people picture their own success story.
It’s not about you.
Shift the focus on how life looks after you do your job.
That’s what gets people to hit “buy.”
#2 — Let success stories do the talking
So what happens when people hear about someone else’s win?
They often end up, “If it worked for them, it’ll work for me too.”
So make sure your reviews hit the big stuff — the jaw-dropping changes.
Plaster these wins on your landing pages.
And make sure these are wins people actually care about.
Keep that optimism rolling.
Get people to picture themselves as the next success story.
Because if others got results, why wouldn’t they? This is also known as the bandwagon effect.
Noom leans hard on user testimonials showing real people.
They focus on stories of actual people who built healthier habits (and kept them).
It’s less “miracle diet” and more “hey, this actually works”.
And this makes new users feel like they can get lasting results, too.
When done right, social proof does double duty.
It builds trust and boosts optimism.
Remember, just be smart about it.
Don’t overhype reviews.
Stick to genuine experiences that show believable transformations.
#3 — Sell the quick fix and the big payoff
Quick wins are cool.
But lasting improvements are even better.
People are all about long-term progress — and optimism bias feeds right into it.
So, don’t just push instant results.
Talk up those lasting benefits, too.
If you’re selling health supplements, for example, skip the plain “boost your energy instantly.”
Add something like, “supports wellness for the long haul.”
Balance the short-term payoff with the promise of ongoing results.
Duolingo, for example, hooks users with quick, bite-sized lessons.
But they also know real language skills take time.
So they let users rack up streaks for daily practice.
You hit milestones along the way.
Even better, you get weekly progress reports showing how much they’ve learned.
These constant nudges feed optimism bias, making users believe they’re on their way to fluency — one quick lesson at a time.
#4 — Make it feel made-for-them
When customers see something customised for them, their optimism kicks in.
Suddenly, it’s not just any product now.
It’s one that fits their needs perfectly.
Personalisation strategies make them think, “Finally, something that actually gets me.”
It feels like it’s built just for them.
This makes it easier for them to believe it’ll do the job.
Glossier’s “Skincare Routine Quiz” guided customers to products that fit their skin type and concerns.
By taking the quiz, people felt more confident that these recos would actually work for their specific needs.
This didn’t just build trust.
It also gave customers the sense that they were on the right path to getting the skin results they were after.
And it could be simple to do this yourself.
A simple questionnaire when people sign up for your site could do the trick.
Not only are you making them feel understood.
You’re also helping them feel optimistic that you can help them get what they want.
#5 — Give them a second shot at excitement
Retargeting isn’t just about nagging people to finish checking out.
You want to bring back those warm fuzzies that got them interested in the first place.
Shoot them a cheeky email to remind them of the thrill they felt when they first heard about you.
Fire up some retargeting ads to bring back the benefits they imagined.
People sometimes just need a nudge to remember they’re close to what they wanted.
So hit them with messaging that says, “Hey, you’re nearly there.”
H&M’s retargeting isn’t just a reminder.
Every reminder is a nudge back to that “what if” moment.
When those items you added to your cart reappear, you remember how those items could look good on you.
They’re playing on optimism bias, bringing back that little spark that this outfit could actually be the one.
Rose-tinted glasses without the red flags
Here’s the thing — optimism bias shouldn’t be used to deceive people.
Stick to what your product actually does, and keep it real.
Skip the wild promises like “lose 20 pounds in two weeks” (unless it’s true).
Spark a bit of optimism, sure, but don’t wander into fantasy land.
At the end of the day, optimism bias is about showing people how you fit into the future they want.
Come up with a marketing persona and frame it around the goals they aim for.
That’s a great way to make your campaigns actually mean something to them.
Help people see a better future without the fluff.
They’ll come back with trust, loyalty — and their wallets.
