Pessimistic induction is a way of looking at things that takes past experiences into account, but it's not always a bad thing! It means that when something bad has happened before, you consider the possibility that it could happen again. For example, if your sibling ate your lunch at school in the past, you might be pessimistic and start to worry that they will do it again. This way of thinking helps you be prepared for a bad outcome, so that you can plan ahead, instead of being surprised and not know what to do.
