Types of cognitive errors specific to intrusive thoughts and OC(P)D
Overimportance of Thoughts and the Need to Control Them
This cognitive error occurs when we conclude that simply because we have a particular thought, it must be meaningful. Similarly, we may conclude that simply because we are thinking about something, this means that it will actually happen. If we have this mistaken belief about the importance of thoughts, we may start to believe that we have to exercise complete control over all our thoughts (which (...) is doomed to fail).
Overestimating Danger
People with OCD often overestimate both the likelihood and the dangerousness of things that may happen. They often view a situation as threatening until they are guaranteed that it is safe. Most people without OCD, on the other hand, assume that a situation is safe unless it is proven to be dangerous.
Intolerance of Uncertainty
Perhaps because people with OCD tend to overestimate the likelihood of danger, they often have trouble making decisions in uncertain or ambiguous situations, then subsequently question whether their decision was correct. Several researchers have found a connection between perfectionism, concern over mistakes, doubts about actions, and OCD symptoms.
Perfectionism
Several studies of OCD have found a connection between inability to tolerate uncertainty and perfectionism. For instance, OCD sufferers believe that their actions must be perfect if they are to avoid criticism from others.
Excessive Responsibility
If you believe that you have the primary power and responsibility to make sure bad things don’t happen, then you probably commit this cognitive error. Since many, if not most, outcomes in life are beyond our control, excessive responsibility will often lead to guilt when bad things happen to us or our loved ones (even when in reality we had no control to avert these things).
