If you don’t look at all of the evidence you can underestimate or overestimate the chance of something happening. For example, a person with agoraphobia might say that they have a 100% chance of having a panic attack if they go to the store or ride the busy, when in reality the chances are a lot less. Others may think that everyone can see them shaking or sweating when in reality most people are probably not watching. Unless you know all the evidence, you may be jumping to conclusions.
