Know that Within 30 Days 80% is Forgotten

Know that Within 30 Days, 80% is Forgotten – comes from the Free Guide – ‘Are you frustrated by training that creates short term interest but not long term change?.

In the mid-1800s, a German Psychologist carried out a series of tests to understand how much he remembered over time. He used 3 letter cards and plotted his research. His name was Hermann Ebbinghaus, and his research became known as the ‘Forgetting Curve’.
In essence, Hermann identified that we forget over 80% of what we learn within 30 days. That is unless we do something with the learning. For example, repeating the learning will significantly increase our chances of remembering it for the long term

Action; work on the forgetting curve

The impact for Learners is that they will forget what they have learnt unless they repeat the learning, apply, and/or use it. If the learning simply stays on slides, learners will forget it. Here are 3 ways you can help the Learners to remember more:

  • The day after the training, ask the Learners to teach someone else one thing that they learnt at the event.
  •  10 days after the training, suggest that the Learners make a diary reminder to re-write their notes.
  • 30 days after the training, email the Learners a task related to the learning.

Ebbinghaus’ Forgetting Curve and the Spacing Effect were large contributors to designing Sticky Learning ® because we wanted scientific research to be the driving force behind how we learn best.
