There are many points in our daily life where we might be mistaken about things or have cause to doubt them. As an exercise, I want you to think about the types of mistake that are possible and what that mistake is due to. So, for instance, I might think that today is Tuesday, when it is actually Thursday, which I could consider a lapse of memory. Set your answers out in a table like this:

Try and cover as many different types of mistake as you can think of (there is no need to list more than one example for each type - confusing Tuesday and Thursday is an example of faulty memory, so there is no need to list other examples).

Once you have done this, move on to the next section.
