Defensive pessimism

Defensive pessimism is a way of thinking that involves imagining the worst-case scenario. It's a type of coping strategy, which means it's a way of dealing with uncomfortable or scary emotions. This strategy helps you prepare yourself for any possible outcomes. When you use defensive pessimism, you try to think of all the bad things that might happen as a way of calming your nerves, and then making sure you are prepared. This way you can feel ready for any problem that may arise.
