The Zeigarnik Effect is a psychological principle that keeps viewers glued to your videos — and in 2026, understanding it can be your biggest retention hack. Named after psychologist Bluma Zeigarnik, it explains why people remember incomplete tasks better than completed ones. Smart YouTube production companies use this principle to structure videos that viewers can’t stop watching.
This guide explains how the Zeigarnik Effect works and how to apply it to your video content strategy. If you want help producing high-retention videos, explore our list of top video marketing companies.
But what is the Zeigarnik Effect?
Back in the 1920s Bluma Zeigarnik, a Lithuanian psychologist was having dinner with friends when she noticed that the restaurant staff could remember long and complicated orders perfectly.
But once the order was delivered and done, they completely forgot it.
She was intrigued about this, so she dove into studying it.
So, Dr. Zeigarnik discovered people tend to remember tasks that are still in progress a lot better than ones they’ve already finished.
Ok, but what does this effect have to do with videos.
Do you know those videos that get you hooked with a great question but they wait until the video is almost over to tell you the answer? Or make you wait for part two?
Well that’s The Zeigarnik Effect right there.
It’s basically your brain getting all hooked on something that’s left unfinished and making you want to stick around to see how it wraps up.
Or it just leaves you with “So, what’s the answer? Where can I find more info on this?”.
So let’s see how you can integrate The Zeigarnik effect in your video creation.
How to use The Zeigarnik Effect in B2B video marketing?
It’s easier than you might think.
You just have to spark curiosity in your viewers, and that’s where the magic happens.
Below we’re going to talk about some tricks you can use in your videos to keep your viewers hooked.
We’ll show you how to create moments where they can’t help but stay engaged.
Hook’em right from the start
Grab your audience’s attention right at the beginning with something juicy. Something that makes people stop scrolling or hitting the exit button.
And why stop at just one hook?
Sprinkle in multiple curiosity points throughout your video.
Keep that momentum going so the excitement doesn’t fizzle out. Think of it like a movie trailer—every few seconds, there’s another moment that makes you want to see more.
So create a little bit of suspense to keep viewers engaged, watch longer, and come back for more.
💡 Also it’s a great time to link stuff together: Connect your different content pieces (articles, videos, podcasts) to create a choose-your-own-adventure journey of awesome content.
Example
Brian Dean knows exactly how to grab attention in seconds.
He opens by promising to show you how to rank on the first page of Google.
But instead of diving right into the how, he pulls you in by sharing his own experience, making you curious to see what worked for him.
Sam Oh nails the Zeigarnik effect claiming “Google hates AI content.” sparking curiosity.
He takes the Zeigarnik Effect even a step further, challenging himself to write and rank an article in under an hour.
Now you’re hooked, waiting to see if he can actually pull it off.
How to hook your audience from the start?
🎬 Make bold claims and don’t tell you audience the answers right from the start
🎬 Show unexpected visuals – Make your audience wander “what is this all about”. But don’t let them be confused for too long.
🎬 Add midway hooks – At key points ask new questions or tease upcoming sections.
Create open loops
Open loops are a true example of the Zeigarnik effect.
Not knowing their answers makes us feel unsettled and it is what keeps us reading or watching.
It’s like when you start reading a book and can’t put it down because you just have to know how it ends.
🧩 Why it works: Our brains need closure, so when you introduce a question or start a story but don’t immediately resolve it, people stick around to get the answer.
Example
Semrush keeps you on the edge by creating an open loop in their thumbnail and title teasing a new SEO approach that will supposedly change everything.
They make you stick around and watch the videos because now you need to know what this big change is and how to prepare for it.
This one hooks you with rapid-fire questions right from the start, making you eager for answers.
Just as you’re processing all these ideas, boom!
The video cuts abruptly and the woman starts presenting Synthesia.
This switch makes you stop and pay attention, wondering “Wait, what just happened? What is this?”
And that just keeps you engaged all the way through.
How to create open loops in your videos?
🎬 Open idea with open ended questions – Our human curiosity will kick in. You can add numbers and statistics into your questions to wow or put your audience to think.
🎬 Use open loops in your titles and thumbnails – Make your video titles and thumbnails hint at something but don’t give away the whole story.
Create unresolved problems
This one’s kind of like open loops, but with a twist.
Instead of just teasing something, you show a task or a story unfolding but don’t finish it right away. You make your audience wait for the resolution, keeping them engaged and watching longer.
It’s like a detective movie. You see the crime happen, but you don’t get the full picture until later.
Or a reality show where they say, “And the winner is…” but cut to a commercial before announcing the name.
That tension makes you need to stick around.
🧩 Why it works: We don’t like not knowing how something turns out, so we stay engaged until we get the answer.
Example
Spendesk’s product video feels more like an action movie than a B2B ad.
And that’s exactly what makes it so engaging.
It starts off with an intriguing mission, where you have no idea if the team will pull it off.
This creates suspense, making you stick around just to see how it all unfolds.
Will they make it? You have to keep watching to find out.
How can you apply this in your videos?
🎬 Start with a challenge – Open with a relatable problem that your audience faces.
🎬 Leave them hanging – Don’t reveal the fix right away. Talk about the struggles. This builds tension and makes viewers want to find out the answer.
Start in the Middle of the Action
One of the best ways to hook people instantly?
Drop your audience right into the middle of the story.
Instead of setting things up slowly, start with a moment of action, a surprising statement, or even a snippet from an interview.
Something that makes them ask, “Wait… what’s going on here?” Then, once you’ve grabbed their attention, backtrack and explain.
Think about it like this: If a movie started with “Once upon a time…” you might zone out.
But if it started with “The bomb was set to go off in 30 seconds.” you’d be locked in immediately.
🧩 Why it works: When you start with a mystery, a conflict, or an intriguing moment without immediately explaining everything, people stay in to fill in the gaps.Example
Ahrefs wastes no time grabbing your attention.
Their interview with Delbert Ty starts with a shocking revelation about three of his best viral campaigns: the news crew, the police… wait, what?!
It throws you straight into the middle of the action, making you desperate to know what happened next.
How to apply this in your B2B videos?
🎬 Jump in the middle of the story – You can do the same in a B2B video—start with a frustrated business owner struggling with an issue, then rewind to show how your solution changes everything.
🎬 Use snippets from interviews or testimonials – If you’re featuring customer stories, don’t start with a long-winded intro. Start with a powerful quote like “We were overwhelmed, nothing was working for us” as people will be curious to know what was the problem.
🎬 Show, don’t tell – Open with a chaotic scene: a team scrambling to meet a deadline, a marketer staring at confusing analytics, or an engineer frustrated by a broken system. The visuals can hint a problem so viewers stay engaged to understand what’s going on.
🎬 Always backtrack to provide context – Once you’ve grabbed attention, rewind and explain. You don’t want to let your audience be frustrated.
Showcase something unfinished
Our brains hate loose ends—we crave resolution.
And when videos present something that’s in progress but not complete, whether it’s a tutorial, a story, a visual, or even a product demo it creates an itch in our brains that needs to be scratched.
That’s why we stick around and watch the whole video or even seek out more content just to get that satisfying sense of closure.
🧩 Why it works: When something is left unfinished, it lingers in our minds, making us want to resolve it.
Example
In this video, Grammarly walks you through the entire tutorial, but they don’t give everything away.
They strategically don’t tell you all the details about citations. They make you visit their blog for more information.
How to showcase something unfinished in your videos?
🎬 Keep people in suspense with case studies – Start with a business problem but don’t reveal the full solution right away. Walk viewers through the journey, hinting at a transformation, but save the final reveal for later in the video or even in a follow-up piece.
🎬 Multi-part tutorials – Instead of giving away everything in one go, break it up into segments. End part one with a teaser for the next tutorial.
Tease future content
Mention something interesting that will be revealed later in the video to create anticipation and give viewers a reason to come back and watch more content.
Filmmakers and storytellers have been using this trick forever.
Think about every Netflix TV show cliffhangers where every episode ends right before the big moment, so you have to tune in next week.
🧩 Why it works: When you hint at something just out of reach, you create anticipation. And as we’ve said a million times by now, our brains need that closure and if we don’t get it right away we click on “next episode” or your next video on the playlist.
Example
This video constantly teases what he will talk about in the video.
It kicks off with a question for which you don’t have an answer right away.
The speaker shares how Shopify helped him to build anticipation.
Then, just when you think you’re about to get the answer, another hook drops about their first sale which you’ll also find about later in the video.
How to tease future content in your videos?
🎬 Tease the next episode – If you’re running a video series, mention what’s coming up next and why they can’t miss it.
🎬 Use coming up teasers – You don’t need to wait until the end to tease future content. Drop a quick “Coming up later in this video…” teaser in the first few seconds to keep people watching.
🎬 Product sneak peeks – If you’re launching a new feature, show just a glimpse but hold back the full demo for a future video or a live event.
🎬 Event teasers – Instead of giving away all the info, provide just enough to spark curiosity.
Use powerful visuals and sounds
It’s no need to say that a video without good visuals and sounds is useless.
They should be used strategically to create whatever you want to create tension, spark curiosity, and so on.
They should embrace your whole concept.
🧩 Why it works: Same as all of the above. Music that builds tension but leaves you without a resolve or images of something incomplete or unclear make or brains look for completion.
Example
This video doesn’t need words.
It relies entirely on visuals and music to create excitement.
The visuals transport you straight into the conference atmosphere, making you feel like you’re already there.
The upbeat soundtrack builds anticipation, and by the end, you just want to join the event.
So just as you start getting curious, they redirect you to their website for more details.
How to use engaging sounds and visuals to keep people hooked?
🎬 Play with unfinished visuals – A half-loaded screen, an incomplete chart, or a blurred-out product teaser to create an open loop in the viewer’s mind.
🎬 Use unexpected cuts and transitions – Cut to black right before a reveal or shift to another scene immediately after a person starts saying something important.
🎬 Use suspenseful music and play with sounds – Have you ever heard a ticking clock in a video and made you think something is urgent? Background sounds like slow-building music, heartbeat effects, or sudden silences keep your audience engaged.
