That&#x27;s not what the article is going for, and that&#x27;s the common mistake I see in teams.<p>A thick skin is necessary, but the point of psychological safety is that it must be normal and expected for someone to make mistakes and to be wrong. It happens inevitably. How teams handle it is the important part. The most successful teams I&#x27;ve experienced are those where someone can say &quot;yeah, I messed up, I&#x27;ll fix it&quot; and the team sees this as a necessary part of a team&#x27;s long term function.<p>That means nobody on the team says &quot;I told you so,&quot; and that team members can disagree intensely without making it personal or emotional.<p>The big problem with &quot;without making it personal or emotional&quot; is that the people most guilty of making disagreements personal or emotionally charged are also least likely (in my experience) to recognize that they&#x27;re instigating. These people are toxic without realizing it themselves.
