Psychological Safety

Definition: Psychological Safety is feeling able to show and employ one’s self without fear of negative consequences of selfimage, status, or career.
An alternate definition is: one’s emotional ability to express oneself in a virtual community without fear of negative consequences in relation to well-being, self-image, and status.
Zhang et al., 2010 mention that a significant antecedent (~a preceding/preexisting thing) of psychological safety is TRUST. Psychological safety and trust are playing a crucial role in knowledge sharing.
