Forced collaboration in agile/lean initiatives due to increasing business demands and delivery speed can lead to collaboration fatigue and decision fatigue. This stress response can cause people to exhibit traits of the "dark triad" - narcissism, psychopathy, and Machiavellianism - in interactions. If left unaddressed, there is a risk this could develop into "dark collaboration" where people are only interested in their own needs and avoiding discomfort. The greatest threat is a shift toward "happy making" collaboration that prioritizes comfort over the critical thinking needed to drive innovation. Organizations must embrace neurodiversity in collaboration and accept that difficulty is often a sign they are having important challenges.
