I love the topic and like this particular article. Having said that, this still feels like a puff piece. The notion of psychological safety certainly matters but not always. My experience is it matters less when you have teams made up more of &quot;thinkers&quot; (vs &quot;feelers&quot;). Also matters less when the team has a clear vision and set of requirements and just needs to adapt their past expertise to minor variations in new problem. Sometimes teams are more efficient and innovative when truth wins over harmony. Depends on team&#x27;s purpose, etc. Let me be clear, I prefer the more psychologically safe mode of group work. Yet it&#x27;s still pretty clear to me that hinders, not helps, in plenty of cases.
