Good learning happens through making mistakes.
Just seeing something many times doesn't mean you'll remember it well.
You've seen the Apple logo so many times.
Of course, you know all the features.
But then when you quiz people and test them, and I do this in my class, people aren't sure.
Is the bite on the left or the right-hand side?
Is there a stem or a leaf?
The best way to remember something is to, again, failures.
I'll have you draw it without looking at it and you struggle and wait, is it on the left or right?
Is it a stem or a leaf?
And you're starting to question all of these things.
Then when you look at the logo again, you're going to engage in better learning than if you hadn't done that errorful kind of trial beforehand.
It's a great question.
And memory is really a mental representation of the past.
And by its very nature, it's reconstructive.
It's never always accurate.
And I think that's why it's so mysterious and fascinating that you and I can see the same event and then remember it differently a week or a day later.
And it starts kind of almost at the sensory level.
And sometimes our mind plays tricks on us.
And that's how I got interested in this field, that how can I think I know something and yet not know it as well as I do?
