The experience of psychological safety is essential for the functioning of teams and organizations. It is defined as a shared psychological state within a group that stems from members’ experiences. Leadership plays a key role in shaping psychological safety. A team is understood here as a group with a leader and a common goal. The appropriate level of psychological safety is relative to the group’s purpose—it must be sufficient to support the goal but not necessarily maximized. While psychological safety in non-professional life context can enhance workplace well-being, it must be balanced with the psychological safety of the work context. The analysis in this chapter draws on Jürgen Habermas’s theory of knowledge-constitutive interests to explore how different types of knowledge interests shape work requirements and psychological safety. The framework helps identify key factors that support the effective leadership of psychological safety in goal-oriented professional environments.
