A 2006 study found that one negative person in a five-person group cut performance by 40%, quality by 25%, and increased conflict by 50% in just 30 to 60 minutes. The speaker argues chronic exposure to toxic people damages your mental health and says you need to let them go.

Chapters

Negative people ruin your life. There was a study that was done in 2006 called the Bad Apple Effect, where they took a group of five people and randomly added a negative person to some of the groups to see how it would affect the groups while working on tasks. Groups with one negative person did 40% worse on all of their tasks and the quality of their work decreased by 25%. They also found that the groups with a negative person had 50% more conflicts, which led to more disagreement and less collaboration. The crazy part, though, like the real crazy part, is these sessions were only about 30 to 60 minutes. Some of you have had a negative person in your life your entire life. Imagine what they are doing to you mentally. You have to be okay with letting them go because your mental health is so important that you need to prioritize that over everything else in your life.
