The learning pyramid. We can only remember 10% of what we read?

We tend to remember,

• 10% of what we read - eg. books, articles, research journals, etc
• 20% of what we listen to - eg. podcasts
• 30% of what we see - eg. pictures
• 50% of what we see and listen - eg. movies, online courses, exhibitions
• 70% of what we say, write, and discuss - eg. participating in a discussion, writing blogs, giving talks or presentations
• 90% of what we say, do, and actively interact with - eg. teaching

This is known as learning pyramid or cone of experience, developed by Edgar Dale.
