For decades, the 70-20-10 model has shaped how organizations think about learning and development. The premise is simple and appealing: roughly 70% of learning comes from experience, 20% from social interaction and mentorship, and just 10% from formal instruction.
It’s elegant. It’s influential. And in many cases, it’s right.
But there’s a catch. When the model was first articulated in the 1980s, it largely described how experienced professionals developed leadership skills over time. It assumed something important: the learners already had a foundation.
So what happens when they don’t? For career changers, new technical learners, and people entering entirely unfamiliar fields, the 10% isn’t a small slice of the pie. At least at the beginning, it’s the whole bakery.
A Misunderstood Model for Workplace Learning
The 70-20-10 framework was based on research conducted by the Center for Creative Leadership in the 1980s. The takeaway from that work was executives reported learning the most from on-the-job experiences, followed by interactions with peers and mentors, and finally from formal education.
That insight still holds up. Formal instruction alone, especially boring or poorly developed lectures, slide decks, and training modules, rarely produces mastery. The issue isn’t that the model is wrong. The issue is that it’s often applied without asking a crucial question: Does the learner already understand the fundamentals?
The 70-20-10 model works beautifully when someone already knows the basic concepts of a field. But for someone who’s completely new to a discipline, the model can fail spectacularly. You have to know some key concepts and terminology first.
Imagine handing someone a set of car keys to someone isolated on an island who has never seen a car and saying, “You’ll learn best by driving.” It might sound reasonable — until you realize the person has never seen a steering wheel before. Without even a basic understanding of how a car works, the experience isn’t educational. It’s just confusing.
Medicine offers an even clearer example. We don’t hand first-year medical school students a scalpel and say, “Learn by doing! Try performing surgery.” Medical education front-loads years of structured learning before clinical rotations begin. Medical school drills students on the fundamentals of anatomy, pharmacology, and pathology for a reason.
The reality is that if you jump straight into the deep end of a subject, you can’t troubleshoot what you don’t understand. Experience only teaches something if you’re equipped to interpret what’s happening. Without that context, it’s just noise.
Learning Styles Are the Astrology of Education
If you’ve spent any time in education or corporate training, you’ve heard it: “I’m a hands-on learner.” The implication is some people learn best by doing, while others prefer reading or listening.
It’s nonsense.
The research behind learning styles has been repeatedly debunked. The VARK model (Visual, Auditory, Reading/Writing, and Kinesthetic) has zero legitimate data to back it up. Study after study has found little evidence people actually learn better when instruction is tailored to these supposed preferences. The learning styles are about as scientifically robust as astrology signs. A teacher wouldn’t accept the excuse, “I’m a Capricorn, so I only learn when Mercury is in retrograde.” Yet we routinely accept, “I’m a hands-on learner,” as if it’s a cognitive law of nature.
Doing something hands-on can absolutely help learning. But it isn’t unique to any group of people, and it certainly isn’t the only effective method. Anybody can learn in any number of ways.
An excellent counterpoint to the “hands-on learning” fad is the work of physicist Richard Feynman. Feynman popularized a simple test of real understanding: if you truly grasp a concept, you should be able to explain it clearly to someone else.
Understanding isn’t measured by activity. It’s measured by clarity, and you can build that clarity in many ways. You can explain a concept to someone else out loud. You can also use flashcards and spaced repetition. Some other ways include writing summaries in your own words, solving practice problems, and studying structured material. None of these methods requires a physical task. But they’re all incredibly effective at building the mental models that make experience meaningful later. So when someone says that they’re a hands-on learner, that may be true, but it’s definitely not the only way that person learns.
The 10% Takes the Longest, and That’s the Point
One of the unintended consequences of the 70-20-10 framework is it subtly devalues formal learning. Ten percent sounds small and maybe even optional. But for someone entering a new technical field, such as IT, cybersecurity, data analytics, or engineering, that 10% can easily represent the largest chunk of time in the entire journey.
Think about going to the gym. Eating one piece of broccoli doesn’t make you healthy, especially if you skip the workouts entirely. Foundations take time. They’re not glamorous, but they’re essential. The same principle applies to technical learning. When foundational knowledge is weak, the gaps don’t stay small. They multiply.
In IT, for example, someone who lacks basic networking knowledge might find themselves constantly searching for answers online. They’ll recognize symptoms but lack the conceptual framework to interpret them. They experience a phenomenon that sometimes feels like the WebMD effect for technology problems.
Strong foundations change that. They allow learners to recognize patterns, make predictions, and diagnose problems more efficiently. However, building that foundation isn’t a one-time event. It requires repetition. Beginners need the kinds of activities typically lumped into the “10%” bucket, which is precisely why that bucket deserves far more attention early in the learning process.
Rethinking the 70-20-10 Framework
Please know this doesn’t mean the 70-20-10 model should be thrown out. For mid-career professionals expanding existing skills, the model is almost tailor-made. Rather than replacing the 70-20-10 framework, it may be more useful to reposition it. Think of it less as a universal learning formula and more as a model for ongoing professional development. It describes how people grow after they’ve already built a foundation.
For learners starting from zero, the ratio should look very different in the early stages. Formal training needs far more weight during what we might call the foundation phase. Structured learning builds the vocabulary, mental models, and conceptual scaffolding that make experience valuable later. Once that foundation is in place, the ratio can shift. Experience takes over. Mentorship becomes more powerful. Then the model starts working exactly the way it was intended.
For instructors and program designers, the key question isn’t whether experiential learning is valuable. It’s whether the learner is ready to learn from experience yet.
A Challenge for the L&D Community
The learning and development industry loves innovation. New frameworks, new methodologies, new philosophies. But sometimes, in the rush to embrace “modern” learning approaches, we undervalue something that remains deeply important: structured instruction.
The 70-20-10 rule itself isn’t the problem. Misapplying it is. When we assume every learner should start with experience, we risk leaving beginners without the tools they need to make sense of what they’re experiencing. And that doesn’t accelerate learning — it slows it down.
So before designing a program around the 70%, it’s worth asking a simple question: How solid is the 10%?
