Psychological safety
Psychological safety is being able to show and employ one's self without fear of negative consequences of self-image, status or career (Kahn 1990, p. 708). It can be defined as a shared belief that the team is safe for interpersonal risk taking. In "psychologically safe" teams, team members feel accepted and respected. It is also the most studied enabling condition in group dynamics and team learning research. Overview. Psychological safety has been an important discussion area in the field of psychology, behavioral management, leadership, teams, and healthcare. Results from a number of empirical studies conducted in  various regions and countries show that psychological safety plays an important role in workplace effectiveness (Edmondson and Lei, 2014). It has consistently played an important role by facilitating ideas and activities to a shared enterprise. It also enables teams and organizations to learn and perform and in recent years, it has become a more significant organizational phenomenon due to the increased necessity of learning and innovation. History. The term "psychological safety" is believed to have been first employed and explored by organisational researchers Schein and Bennis in the 1960s, defining it as a group phenomenon that reduces interpersonal risk: i.e.  psychological safety reduces "a person's anxiety about being basically accepted and worthwhile"; recognising the importance of psychological safety in relation to uncertainty and change. Point 8 of W. E. Deming's 14 Points For Management, written in 1982, of "Drive out fear, so that everyone may work effectively for the company" highlights a similar growing realisation, in contrast to previous Taylorist management approaches, that the creation of environments where it is interpersonally safe to raise concerns is of crucial importance to realising high quality business outcomes. Explicit interest in psychological safety was renewed by Kahn in the 1990's , through qualitative studies which showed that psychological safety enables people to "employ or express themselves physically, cognitively, and emotionally". This was in parallel with emerging progressive management paradigms at the time such as safety culture and the Toyota Production System (TPS) that introduced a physical representation of psychological safety, the Andon Cord, which explicitly provides employees with the empowerment to raise issues or concerns. Social aspects. Psychological safety is a group-level phenomenon. Research on team effectiveness emphasises input-process-output (IPO) models, and some studies see psychological safety as an input that promotes team performance through team learning as  a mediator (process). A significant antecedent of psychological safety is trust (input) which plays an important role in knowledge sharing as well as a mediating (process) role partially (Zhang et al., 2010). A number of studies show that psychological safety is a mediator of relationships between antecedent (similar to 'input variables' in the input-process-output model) including organizational context, team characteristics and team leadership, and outcomes (similar to 'output variables' in IPO model) of innovation, performance, learning, and improvement in or by a team. Although psychological safety has a significant effect as a mediator in explaining team outcomes, it  also plays a role as a moderator. Here, psychological safety as a mediator acts as an input in case of teamwork as well as process or emergent state. Due to the boundary condition, it may not help teams to learn when particular conditions such as absence of interdependence are supporting teamwork. When team members are motivated at work and want to share an idea for improving performance, they frequently do not speak up because they fear that they will be harshly judged. When psychological safety is present, team members think less about the potential negative consequences of expressing a new  or different idea than they would otherwise. As a result, they speak up more when they feel psychologically safe and are motivated to improve their team or company. Given its current status (in 2022) as an emergent type of safety (e.g. as compared with the older idea of "physical" safety), its is easy to confuse psychological safety with more well-established concepts such as trust and psychological mindfulness. A primary difference between psychological safety and trust is that psychological safety focuses on a belief about a group norm – emerging from the group's "common" experiences/perceptions regarding the expected consequences  from taking interpersonal risks, in context of its social norms defining the 'correct' in-group behaviours and interactions (e.g. as part of organisational safety culture/climate). Compared with the phenomena of trust, psychological safety has been observed to occur more often in context of larger groups than the typically dyad focused nature of trusting relationships(e.g. as a relationship clinicians have in mind with their host organisations); additionally a sort of 'temporally immediate' (i.e. "right now") feeling seems to characterise the experience of psychological safety, rather than the typically deferred (i.e. "much later") feeling co-present in experiencing trust. These differences  between the concepts of psychological safety and trust are becoming established in institutional/organisational study contexts, where trust focuses on a belief and view that one person has about another, whereas psychological safety can be defined by how members of larger social groups think they are viewed by others in the group. Mindfulness is also different from psychological safety in that mindfulness is about being aware of one's surroundings but psychological safety is focused on being respected in a group. Moreover, the most studied result of psychological safety, team learning, is defined as a group adjusting to its surrounding  through outwardly sharing observations about their environment. However, mindfulness is an individual becoming internally enlightened about his/her environment. Benefits. Psychological safety benefits organizations and teams in many different ways. The following are the most widely empirically supported consequences of a team being psychologically safe: Leaders as well as some aspects of the team can increase team members' psychological safety. Two aspects of leadership have been shown to be particularly instrumental in creating a psychologically safe team. They are leaders using: There are also two aspects of a team that help improve its psychological safety. They are:
