TL;DR
Adult learners now want their training in 90-second bites, not 40-minute modules. This month I trace microlearning from Encyclopedia Britannica to Cliff Notes to TikTok, and share how we’ve rebuilt our PESO Model Certification® around the same principles. Because bite-sized, visual content is not just better learning, it is also the price of admission for visibility engineering and the see, engage, respond, share loop your audience actually completes.
Key Insights
- Adult learners now prefer 3 minutes or less per lesson, ideally 45 seconds to 2.5 minutes, and research shows 15 to 60-second chunks boost retention.
- The new PESO Model Certification® has been completely refreshed around microlearning: shorter lessons, workbook activities, AI prompts for when you get stuck, and a worksheet to document progress.
- Spin Sucks runs on the same principles internally, with Poppy’s twice-weekly Slack “Poppyseeds,” Gini’s weekly Snack Packs, and one-page QRGs replacing marathon training sessions.
- Adults despise role-play. Private practice, combined with low-stakes demonstration, produces better skill transfer and less anxiety.
- The same logic applies to your communications. Bite-sized, visual content is the price of admission for visibility engineering, the see, engage, respond, share loop your audience actually completes.
- Coordinated isn’t the same as integrated. A drumbeat of small, applied, repeated lessons compounds for your team’s expertise and your audience’s attention.
The Britannica Was My TikTok
Who else remembers the giddy thrill of sitting down with a brand-new set of Encyclopedia Britannica?
I was SO excited when we finally got a set in our house. I could research my school paper in record time. (Record time being, you know, an entire weekend.)
Then came university library stacks, hours hunting down references for semester projects, running from library to library to find the right article.
Study groups where lectures and books were outlined, hoping to capture the most important elements.
Flashcards created, the paper kind – on index cards – not the new kind that are digitally developed from class notes or the syllabus.
Classmates quizzed live until someone cracked into a bag of chips. (Think Elle Woods in the Harvard library, minus the perfect ponytail, of course.)
Learning meant reading books. Long, long books.
Our great cheat? Cliff Notes.
Which, in hindsight, was microlearning before microlearning was a thing.
The “Hmmm, I Don’t Know” Era Is Officially Over
Back then, if someone asked a question and you didn’t know the answer, you said, “Hmmm, no idea,” and that was that.
Today? We grab our phones and ask our favorite AI agent before the question is even finished hanging in the air.
Oh, how things have changed. And as a learning professional for, well, longer than I care to admit, I have witnessed the entire evolution.
And I love it.
Twenty Minutes Was the Floor. Three Minutes Is the Ceiling.
When I first started building learning programs, our standard “seat time” was 20 to 40 minutes per module. (My personal Mount Everest? An early career assignment to build a course on thermogravimetric analysis. Yikes.)
Fast forward to today: smartphones, Slack pings, kid pickups, dinner prep, and inboxes that never sleep.
No time for traditional learning.
Adult learners now prefer three minutes or less. Ideally, 45 seconds to 2.5 minutes max.
That’s not a preference. That’s a survival skill.
Research backs it up. Bite-sized content delivered in 15 to 60-second chunks boosts retention.
It matches the way our brains actually want to work: pause, replay, and resume.
And, critically, it lets us apply what we learn immediately, which is when learning really sticks.
The China Lesson I Didn’t See Coming
One of the most fun projects of my career was helping implement HEP (Human Error Prevention) in manufacturing.
Equipment design. Room signage. Tool layout. Lighting. Procedures. Training.
Everything and anything that could cause an interruption or mistake was evaluated and addressed.
We moved procedures from 20-page, text-heavy Word docs into two-page visual, photo and icon-rich recall guides paired with shorter, skill-focused training.
My biggest challenge wasn’t the content. It was my colleagues in China.
Not because they weren’t willing. Just the opposite.
Their learning was rooted in rote memorization and beautifully precise procedure-following.
One friend explained that university exams asked things like, “On page 325, paragraph 2, what did the author say about XYZ?”
So, a 20-page SOP wasn’t intimidating to them. It was comforting.
So, when I came in waving my visual one-pagers, the question was very reasonable.
Why?
After many trips, a lot of dumplings, and even more relationship-building, they trusted the methodology and began to apply it.
And watching them adopt early microlearning was one of the most rewarding moments of my career.
Yes, We Drink Our Own Champagne
Because of all the lifestyle and technology shifts, things at Spin Sucks are changing right alongside the science.
We’ve completely refreshed our PESO Model® Certification with the same principles I’m preaching here.
The lessons are shorter. Every lesson now comes with a workbook activity so you can practice exactly what you just learned, an AI prompt for when you get stuck (because you will), and a worksheet to document the work as you go.
The point?
You can knock out a lesson when your schedule actually allows it. Between meetings. After kid pickup. While dinner simmers. Saturday morning with coffee.
Wherever life cracks open a short window.
It is no longer “block off a whole weekend and pray.” It is “open the next lesson and go.”
Same content depth. Smaller bites. Built-in practice. AI safety net.
That is what adult learning is supposed to look like in 2026, and it is what the new certification feels like to walk through.
Let’s Stop Pretending. Adults Hate Role-Play.
Real talk: adults despise role-play. It’s awkward. It feels fake.
It spikes anxiety and shrinks the safety we need to actually try something new.
So, at Spin Sucks, we skip it.
Instead, our learners get a private space to think, practice, and try things, then demonstrate when they’re ready.
Shocking what happens when grown-ups aren’t forced to “pretend to be the client” in front of their peers or boss.
Meet Poppy. She Drops Seeds.
One of my favorite microlearning moments inside our team comes from Poppy, our internal virtual trainer.
Twice a week, she drops a “Poppyseed” 🌱in our company Slack: a quick question, scenario, or nudge. Team members respond in the thread. Gini wraps the day’s thread with a quick summary.
It’s fast. It’s fun. It’s searchable. And no one has to block out time on their calendar to learn something new.
For step-based work, such as updating our website or loading courses into our LMS, we build QRGs (Quick Reference Guides).
One-page, visual instructions stored on our internal site. No 80-page binders. No “Wait, where did Shelly put the document about that thing?”
Just pull it up when needed.
Snack Packs Beat Full Meals
Gini does the same in her weekly Snack Packs in the newsletter (which you can subscribe to here, if you haven’t already). She gives you micro PESO Model® activities you can knock out between meetings, or right after that completely unnecessary bio break:
“Spot the leak. Pull up the last LinkedIn post, sales email, or slide your team produced from a flagship piece. Read it side-by-side with the original. Did the specific number survive? The time frame? The attribution?”
Three minutes. One insight. Real practice.
That’s not a “lesson.” That’s a habit-builder.
Why My Basil Plant Has a YouTube History
How many times last week did you turn to YouTube, TikTok, or IG to figure something out? For me? Almost daily. Or maybe even hourly…..
How to properly prune my new basil plants.
Why my refrigerator suddenly decided I didn’t need ice.
What on earth to do with the strange pasta shape my friend brought back from Italy.
The beauty of learning this way is that it’s just-in-time.
I open it, watch, pause, restart, and swap to a different creator if this one isn’t clicking.
No owner’s manual. No journal article. No “see appendix C.” A short answer to a short question, delivered the moment I need it.
Just last night, during a Masterclass session, we kept pausing to ask questions of both the Masterclass AI agent and our personal favorite AIs. Then we’d dive into a deeper conversation about what we just learned.
That’s microlearning compounding in real time.
Communications Has the Same Problem, and the Same Cure
Here’s where it ties back to your work. Gini has been sharing why and how the PESO Model is an operating system. Not a checklist, not a tactic list, and definitely not a free image you swipe off Google. Integration is what makes it compound.
Microlearning works the same way. One 90-second lesson isn’t going to make anyone brilliant. But a steady drumbeat of small, focused, applied lessons, repeated over time, with real practice in between, compounds into actual expertise.
Your communications? Same thing.
One clean LinkedIn post doesn’t build authority. A year of clear, integrated, hub-anchored content does. As Gini put it in her recent PESO Diagnostic of Budweiser’s Super Bowl spot, coordinated isn’t the same as integrated.
A flashy moment with no system underneath is a parade, not an operating system.
This is also the heart of visibility engineering.
In a feed-and-AI-driven world, your audience has to see your message, engage with it, respond to it, and share it before any of it actually counts. Long, dense, three-clicks-deep content does not move through that loop.
Short, clear, visual, sticky communications do.
Microlearning is not just a training tactic. It is the same shape as the content your audience already chooses to consume.
Same goes for learning. Same goes for your audience.
Bite-Sized Doesn’t Mean Lightweight
Communications, just like learning, doesn’t have to be long to be effective.
If you want your audience to see, engage with, respond to, and share what you put out, bite-sized, visual content is the price of admission. Not the watered-down version of your message, the discoverable version.
A clear CTA on your owned media. A 45-second Instagram story that expands on your expertise. A TikTok that delivers one usable insight. A QRG or FAQ your audience actually opens. A “Poppyseed” your audience can answer in 90 seconds. A Snack Pack that turns Tuesday’s downtime into Wednesday’s win.
From encyclopedias to YouTube. From Cliff Notes to AI agents. The literal world is at your fingertips, finally in pieces small enough to digest.
Your Turn (in 90 Seconds or Less)
So, here’s my challenge. How can you use microlearning for your own brain, your team, and the audiences you’re trying to teach, train, and persuade?
And if you don’t know the answer yet?
Hmmm… ask AI.
