5 Cognitive Distortions That Hit When Debugging (And How to Break Them)

Debugging code often leads to common mental traps that can hinder progress. To overcome these cognitive distortions, Cognitive Behavioral Therapy (CBT) techniques can help. Five distortions frequently encountered during debugging are Mental Filter, Catastrophizing, Labeling, Should Statements, and Emotional Reasoning.

Mental Filter involves focusing solely on the one failing test while ignoring the many successful tests, causing an exaggerated perception of the problem. Catastrophizing assumes the worst possible outcome without any evidence, leading to unrealistic expectations about the time required to fix the bug. Labeling occurs when a single mistake is turned into a self-identity statement, such as "I am a bad developer."

Should statements impose unrealistic rules on oneself, like believing one should know the solution or be proficient in the codebase immediately. Finally, emotional reasoning assumes that feelings reflect reality, projecting frustration onto the programming task and believing one is incapable of solving it.

CBT offers specific strategies to combat these distortions. For Mental Filter, deliberately list the successful tests and other working parts of the codebase. Instead of Catastrophizing, ask what the most likely outcome is, rather than the worst-case scenario. To challenge Labeling, replace the identity label with a behavior-focused statement, acknowledging the bug without equating it to one's self-worth.

Replace Should Statements with preferences, allowing for a more flexible and realistic approach to problem-solving. And Emotional Reasoning can be addressed by recognizing feelings as data, not truths, and utilizing a 90-second rule to let frustration pass before returning to the problem.

The Debugging Thought Record is a CBT tool that helps developers document the situation, automatic thoughts, distortions, and reframed perspectives. By regularly using this thought record, developers can become more aware of their cognitive patterns and develop healthier thought habits during the debugging process. Finally, a free CBT toolkit has been developed specifically for developers, providing practical tools to manage cognitive distortions during debugging and other challenging tasks.
