Dichotomous (black-and-white) thinking: meaning and examples

Dichotomous thinking is a common problem best described as black-or-white thinking. People who think this way are unable to see the complexity in people and situations, viewing things as either perfect or horrible. You can spot this behavior in yourself by looking for terms such as ‘perfect,’ ‘failure,’ ‘always,’ or ‘never.’

Common Examples

Imagine you have just finished making dinner and, on the first taste, you feel it’s slightly too salty. You might say something like: ‘This is awful, what a waste of time and resources!’ Or you may even go further and say, ‘The night is ruined.’ In reality, you just added a bit too much salt, and you can instead tell yourself: ‘I added a bit too much salt. I will improve next time. I like how it tastes otherwise.’

Dichotomous thinkers might also come back from job interviews feeling it went awful just because they failed to answer one or two questions. In reality, they answered most questions well and merely failed to recall a simple term that can easily be looked up afterward.

This black-or-white thinking is more often seen in perfectionists, or in people who struggle to put things in perspective. Both tend to create a kind of tunnel vision, where there's only one optimal outcome and everything else is deemed a failure.

Impact on Your Health

Thinking in black-or-white terms can increase stress, lower self-esteem, and even contribute to depression. By removing the shades of grey between success and failure, we set ourselves up for disappointment. When this pattern intensifies, it becomes harder to separate that judgment from evidence that contradicts it.

Self-Correction

Try to spot this type of thinking in your own behavior and replace the thought with something more constructive or rational. Look for words that are absolutes and replace them with softer words such as ‘very good,’ ‘somewhat sad,’ etc. As an exercise, it may help to put these thoughts on paper and write down potential outcomes that are only somewhat positive or negative.

Dichotomous thinking rarely travels alone. It often pairs with overgeneralization, where one bad moment quietly becomes ‘always.’ You can explore every pattern in our mind traps collection.
