According to Brené Brown, a vault is a kind of psychological metaphor for trust. Brown's view of trust is that it is based on seven elements. One of these is integrity, as you have already read. Other elements include setting boundaries and being reliable. Accountability and generosity also feature in the make-up of trust, as does the ability to be non-judgemental about oneself and others. The other element of trust Brown argues for is called a vault. This is the idea that anything private that is shared with you goes into a metaphoric vault. In other words, information and experiences that others share with you are not to be shared with others. Unless permission is sought and granted, confidences will remain in the vault and not shared with anyone, even those closest to us, so that that trust can be properly maintained. Brown says that trust based on the vault concept is a two-way street whereby people can share profound truths about themselves, knowing they will be respected.
