I Built Our Training Program on These 5 Learning Myths. It Was a Costly Mistake.

I still remember the beautiful, color-coded binders. Early in my career, I was tasked with designing a major training program for our customer service team. I had read all the popular literature, and I was convinced I had the secret sauce: learning styles. I spent weeks creating a “multi-modal” experience. We had lectures for the “auditory” learners, detailed workbooks for the “reading/writing” learners, and hands-on activities for the “kinesthetic” learners. The program was a masterpiece of instructional design, or so I thought.

The feedback from the session was great. People enjoyed the variety. But three months later, the performance metrics hadn’t budged. The same old problems persisted. We had invested thousands of dollars in a program that was engaging but completely ineffective. It was a costly, public, and humbling failure. It sent me on a journey to understand the difference between popular learning fads and the actual science of how the human brain learns.

I discovered that the world of corporate L&D is filled with well-intentioned but deeply flawed “zombie ideas”—myths that refuse to die. We cling to them because they sound intuitive, but they are actively undermining the effectiveness of our work. Here are the five biggest myths I’ve had to unlearn, and what we should be doing instead.

1. The Myth of “Learning Styles” (VAK)

• The Myth: Everyone has a preferred learning style, such as Visual, Auditory, or Kinesthetic (VAK). To be effective, training must be tailored to an individual’s specific style.
• The Reality: This is the big one, the undisputed king of learning myths. Despite its immense popularity, there is zero scientific evidence to support the idea that teaching to a preferred style improves learning outcomes. The human brain is a multi-sensory organ. We all learn best when information is presented in a variety of ways that are appropriate for the content, not the person.
• The Right Approach: Use Multi-Sensory Content, Not Learner Styles. Instead of trying to diagnose people, diagnose your content. Ask, “What is the best way to teach this specific idea?” Some concepts are best explained with a diagram (visual). Some are best understood through a case story (auditory). And some skills can only be learned by doing (kinesthetic). A great learning experience is varied not because the learners are different, but because the content demands it.

2. The Myth of the “Forgetting Curve” as Destiny

• The Myth: We forget 70% of what we learn within 24 hours (the “Ebbinghaus Forgetting Curve”), so most training is a waste of time.
• The Reality: The forgetting curve is real, but it is not an immutable law of nature. It describes what happens when learning is treated as a passive, one-time event with no follow-up. It’s a diagnosis of a bad learning process, not a verdict on the human brain’s capacity.
• The Right Approach: Design for Reinforcement, Not Just Delivery. The training workshop is the start of the learning process, not the end. To defeat the forgetting curve, you must design a system of reinforcement. This includes:
  • Spaced Repetition: Re-introduce key concepts in small doses over time (e.g., a follow-up email, a short quiz a week later).
  • Immediate Application: Build projects into the training that require participants to immediately use what they’ve learned on real-world tasks.
  • Manager Coaching: Equip managers to coach their team members on the new skills back on the job. Learning sticks when it is used.

3. The Myth that Gen Z Only Learns in “TikTok-Style” Videos

• The Myth: Younger generations have short attention spans and will only engage with short, flashy, entertaining videos. Long-form content is dead.
• The Reality: This is a dangerous oversimplification. Attention is not a function of age; it’s a function of relevance, engagement, and motivation. A Gen Z employee will absolutely focus for 60 minutes on a deep-dive session if it helps them solve a problem they genuinely care about. They will, however, instantly tune out a boring, irrelevant lecture, regardless of its length.
• The Right Approach: Focus on Engagement and Relevance, Not Just Length. The enemy is not duration; the enemy is boredom. Instead of obsessing over making everything 60 seconds long, obsess over making it compelling.
  • Start with “Why”: Ensure every piece of learning content starts by answering the learner’s question: “What’s in it for me?”
  • Make it Interactive: Even in a longer session, build in “micro-interactions” every 5-7 minutes. Use polls, breakout discussions, and collaborative activities to keep the brain engaged. A 30-minute interactive session is far more effective than a 3-minute boring video.

4. The Myth of the 10,000-Hour Rule

• The Myth: It takes 10,000 hours of practice to become an expert at something.
• The Reality: This is a misinterpretation of Malcolm Gladwell’s popularization of Anders Ericsson’s research. The real key to mastery is not the sheer volume of hours, but the quality of that practice. Ten thousand hours of mindlessly repeating the same action will not make you an expert. It requires “deliberate practice.”
• The Right Approach: Design for Deliberate Practice, Not Just Practice. Deliberate practice has four key components that you can build into your training:
  1. Specific Goals: A clear focus on improving one specific aspect of a skill.
  2. Intense Focus: A distraction-free environment to practice.
  3. Immediate Feedback: A mechanism to know right away how you are doing (e.g., a coach, a simulation).
  4. Constant Discomfort: Always pushing just beyond your current comfort zone. A 30-minute session of deliberate practice is more valuable than two hours of mindless repetition.

5. The Myth that Learning Happens Best in a Classroom

• The Myth: The most effective learning happens in a formal, structured, classroom-style event.
• The Reality: Formal training is an important part of the learning ecosystem, but it’s only one part. Research shows that the vast majority of learning (often cited as the 70-20-10 model) happens on the job, through challenging assignments, and from interactions with peers and managers.
• The Right Approach: Build a Learning Ecosystem, Not Just a Training Calendar. Shift your focus from “running training events” to “cultivating a learning culture.”
  • Champion On-the-Job Learning: Create “stretch assignment” opportunities and project-based learning.
  • Foster Social Learning: Build a culture of mentorship and create platforms (like a simple chat channel) for peer-to-peer knowledge sharing.
  • Position Formal Training as a Catalyst: Use your workshops not as the end-all, be-all, but as a powerful catalyst that kicks off a longer journey of on-the-job application and social learning.

From Myths to Impact

My early failure taught me a vital lesson. In the world of L&D, our good intentions are not enough. We have a professional responsibility to be skeptical of fads and grounded in the science of how people actually learn. By debunking these myths, we can stop wasting time and money on programs that feel good but do little, and start designing learning experiences that create real, measurable, and lasting impact.
