These Are The Reasons Why Learners Forget Your Training

"Training doesn’t help one jot if people can’t remember it in the real world"  —Teresa Ewington

Our biggest goal in training is to get students to remember the material. To do this more effectively, it helps learning what causes the mind to forget things. By getting a clear view of what makes a person forget, we can incorporate key elements into our programs that help counteract those causes. 

Forgetting is an important function. It helps a human filter out trivial things that would clog the brain and override important information. Forgetting helps ease the pain of tragedy and enables a person to continue living without constant sadness. There are times, however, when we not only need to remember, but need to do so at a time when the information is useful.

Let's take a look at the five most common reasons your corporate learners forget your training.


Reason #1: Encoding Failure (Learning Didn't Pay Attention to Content)

This is the most common cause of forgetting. The information never actually made it to the person's memory bank. This happens when a student fails to focus on what is being taught. Maybe they had other things on their mind that day, or the material just wasn't engaging enough to capture their attention. Another reason for not paying attention is that the student didn't see a reason for learning this information; it didn't seem to have a purpose related to the subject at hand. This encoding failure can also occur when someone is being presented with too much information all at once, causing them to have to pick and choose what the brain will retain.

Reason #2: Interference

It is known that recent things we learn are more easily remembered than older information. If both sets of information on the same subject, the newer memories may make it harder, if not impossible, to remember the older ones on the same subject. This is called retroactive interference. If the original information is so strong that it makes learning new information on the subject difficult, it is referred to as proactive interference. This can happen because the first information we learn on a subject is more deeply ingrained and anything that might counteract or clash with that understanding becomes difficult to retain.

Reason #3: Shallow Processing

Deep processing occurs when meaning is placed on the material being learned. When a student can find a reason to retain the information, when an emotion is connected to the material or when more than one sense is used in learning, the memory gains staying power and is more easily brought forth when needed.

If the material can't be connected to a sense or a feeling, the processing is shallow and it does not stay in the brain for any length of time because the brain considers it unimportant and will make room for things it considers more relevant.

Reason #4: What Versus How

Say you are teaching a student the workings of a motor. You can show them a diagram of a motor and explain what the various parts are or you can place a motor in front of them and have them assemble the motor step by step, explaining how each piece fits the whole. The student will more likely remember the second method because the mind is more eager to understand the how and why of something rather than simply accepted what is. By helping a student understand the reasoning behind a concept or the role a concept plays in the subject matter as a whole, it tells the brain the material is important and must be remembered.

Reason #5: Decay or Disuse

The brain tends to take information that isn't used regularly and replace it with material it knows a person needs. Think back to high school geometry. Unless you are an architect or work in some other profession where you need precise angles and such, you don't remember all those formulas for figuring out the various areas of shapes and angles. Your mind needs to regularly go over information previously learned or it places the information in a bin marked useless and locks it away from easy memory. The more ways something is gone over, the more it stays in memory. That is one reason unit reviews and chapter quizzes are so helpful. They bring the material out of hiding and make sure the brain knows you want that information retained

As eLearning professionals, it is almost as important to understand how the human mind forgets as it is to understand memory. Both concepts are part of the same coin and must be addressed together to make a program as successful as possible.


Understanding why learners forget is the first step. Now ensure that learners REMEMBER the knowledge till the time they get the opportunity to apply it. This is critical for the success of your training program. 

Here are 7 proven knowledge retention strategies you can apply in your course design.

Redefining Your L&D Strategy In Disruptive Times: Enter Self-Directed Learning

Lifelong learning is now more important than ever. Technology has brought about many changes in the world of work, and those who don’t adapt will be left behind. This creates a problem for many business owners.  The Future of Jobs 2020 Report by The World Economic Forum revealed: Skills gaps continue to be high as in-demand skills across jobs change in the next five years. The top skills and skill groups that employers see as rising in prominence in the lead up to 2025 include critical thinking and analysis as well as problem-solving, and skills in self-management such as active learning and flexibility. On average, companies estimate that around 40% of workers will require reskilling of six months or less and 94% of business leaders report that they expect employees to pick up new skills on the job, a sharp uptake from 65% in 2018. A significant expansion of remote work is expected in the next few years— employers see the potential to move 44% of their workforce to operate remotely. Since the pandemic started, online learning is on the rise. There has been a four-fold increase in the numbers of individuals seeking out opportunities for learning online through their own initiative, a five-fold increase in employer provision of online learning opportunities to their workers, and a nine-fold enrolment increase for learners accessing online learning through government programs. 50% of employers will speed up the automation of tasks, while over 80% are set to expand the digitization of their work processes. In other words, jobs will disappear, and new jobs will surge. Specifically, they predict around 85 million roles are set to be displaced by automation and 97 million new jobs will emerge by 2025. All these shifts happening so fast require employees to take greater control over their learning journey and at the same time, require employers to act fast to ensure learners have the right information at the right moment.  A lifelong learning approach cannot be forced. That's why there's a huge opportunity for leaders in companies to focus their L&D efforts on empowering employees to embrace lifelong learning and promoting self-directed learning. In the end, not only companies are the ones that will receive benefits for this... lifelong, self-directed employees are the ones who will thrive in a rapidly changing world. Prioritizing self-directed learning is key to developing an adaptive and flexible workforce that is prepared to navigate the uncertain times and the "jobs of tomorrow."

10 Types of Visual Content Proven to Boost Learner Engagement

Humans love visuals. In fact, we are wired to respond more to visuals than to words. That is why we are so hooked on Pinterest and Instagram. This is also the reason why Facebook posts and tweets with images get liked and are retweeted the most. But as an Instructional Designer, what should interest you more is the fact that the human brain can process visuals faster than text. So if you care about creating more engaging eLearning, you MUST include powerful and engaging visuals in your courses. Visuals take away from the burden of reading through tomes of text, navigating language ambiguities, and making sense of jargon and complex sentence structures. Learn the ten most useful tools that you can incorporate into your eLearning courses to get your content to stick and resonate with your audience:
