Why We Forget Most of What We Learn (and How to Fix It)

First, a small celebration. I just graduated with my master's in human resources from Central Michigan University. Confetti, please.

Fire up Chips!

The final class in my program was a research paper, and I picked a topic I genuinely cannot stop thinking about. I studied how training design affects behavior change and skill retention. I know, I know. That sounds like the most HR-flavored thing a person could ever write about. Stay with me anyway, because this one matters for all of us.

Here is the statistic that knocked me over.

Right after a training class, employees apply about 62% of what they just learned. Six months later, that number drops to 44%. After one full year, only 34% is still in use.

62% right after training. 44% at six months. 34% after a year. We spend so much time, energy, and money, and most of it leaks out before the calendar flips.

WHAT?! I am sorry, but that one shook me. Companies invest in training. Schools build entire curriculums. Parents pay for tutors and camps and music lessons. Coaches design programs. And after a year, only about a third of it is still showing up in behavior?

If you are not in HR and you have never thought twice about training design, please do not click away. Because this is not really a workplace problem. This is a learning problem. And learning happens to every single one of us, every single day, in every single part of our lives.

I See This in Myself

Before I go any further, let me show you what this looks like in my own life. I am not pointing fingers from the sidelines here. I am pointing them right at me.

Every year I head to St. Joseph, Michigan for the Midwest Advanced Public Works Institute. I love it. I come home with a phenomenal set of notes, and by phenomenal I mean more ideas than I can possibly count. I come home with phenomenal intentions, too. I am going to try everything I learned. I am going to make all the changes that sounded so perfect for my work. I leave that conference energized, motivated, and ready to lead.

And then I get back to the office.

A mountain of emails is waiting. There is a stack of papers on my desk. My to-do list looks like it sprouted three new pages while I was gone. And still, somehow, I am riding the wave. I walk in with renewed ambition and desire. It feels great.

Then the days go by. Days turn into weeks. Weeks turn into months. Months turn into years. My beautiful notes and big intentions sit in a folder labeled "for later." Out the door goes my plan.

Now, am I a lost cause? Of course not. I retain things. I make real changes. I bring new ideas into my work all the time. But all of the ideas I left that conference with? Every change I swore I was going to make? Oh heck no.

That is the forgetting curve in real life. In my real life. From someone who genuinely loves learning. If it can happen to me, it can happen to anyone.

This Is Not Just a Workplace Thing

Think about your kid sitting in math class. They learn fractions in October. They pass the test. By February they cannot remember how to find a common denominator. Same forgetting curve.

Think about a couple who finally goes to therapy and learns a few healthy communication tools. They practice them for a month. Then life gets busy, and they slip right back into the old patterns. Same forgetting curve.

Think about that work training you sat through in January, where you took beautiful notes and felt fired up. Then you went back to your desk, got buried in email, and never opened the notes again. Same. Forgetting. Curve.

It is not because you are lazy. It is not because your kid is bad at math. It is not because your spouse does not care. Human beings forget. We just do. Especially when what we learn does not match the life we actually live.

What Actually Makes Learning Stick

My research dug into the factors that decide whether a lesson sticks or slips. A few showed up over and over, and once you see them you will start spotting them everywhere.

The first factor is relevance. People retain what mirrors their real life. If your fifth grader is solving word problems about train schedules they have never used, that lesson is going to evaporate fast. If your team got trained on software they do not actually open at work, same thing. The closer the lesson is to the lived experience, the longer it lives.

People retain what mirrors their real life. Anything that does not connect to the world they actually live in will quietly disappear.

The second factor is support. The people around the learner matter more than the content of the lesson. A teacher who follows up. A supervisor who checks in. A spouse who practices the new communication tool with you instead of rolling their eyes. Support is the difference between a skill and a faded memory.

The third factor is opportunity to practice. If you take a class on conflict resolution and never actually use it, your brain throws it out. Same with the French you took in eighth grade. Same with the leadership book you read in March. Use it or lose it is the most accurate cliche in education.

The fourth factor is psychological safety. People learn when they feel safe to mess up. A kid who is afraid of being wrong stops raising her hand. An employee who is afraid of being judged stops trying the new tool. A spouse who has been criticized one too many times stops trying the new approach. Safety unlocks learning. Fear shuts it down.

How to Use This in Real Life

What does learning in real life look like for you?

Here is what I am taking from my research and pulling into my own life, not just my HR practice.

When I learn something new, I am going to ask myself how I will use it in the next week. Not someday. Not in theory. This week. If I cannot find a place to apply it, I am going to make one.

When my son learns something new (we homeschool, so I am real aware of the daily topics!), I am going to look for one tiny way to use it at home. Cook with fractions. Talk about how the science topic is out here in real life. Take the abstract and make it real with our hands.

When I am communicating with someone I love, I am going to remember that one healthy conversation is not the win. The win is the hundredth healthy conversation, after ninety-nine messy ones where we kept practicing the new pattern.

And when I am in any kind of leadership role, whether that is at work or in my home, I am going to remember that learning needs reinforcement. People do not change because they sat through a session. They change because someone kept showing up to practice with them.

People do not change because they sat through a session. They change because someone kept showing up to practice with them.

One Last Thing

We tend to treat learning like an event. We sit through the training, the workshop, the lecture, the lecture from a parent, the heart-to-heart in the kitchen, and we expect the lesson to take. But learning is a process, not an event. The session is the spark. What you do in the weeks after is the fire.

So whether you are a manager developing your team, a parent walking through homework, a partner trying to change a pattern in your relationship, or just a human trying to keep growing, give yourself grace. Forgetting is normal. Practicing is everything.

What is something you learned this past year that you wish would have stuck? Tell me. I want to hear it, because I am willing to bet I can find a way to help it stick the second time around.
