blind walk

a trust exercise used in a group setting (e.g., an encounter group) to help members develop mutual trust. Half of the group close their eyes; the other half become their partners and lead the “blind” people through various experiences. Roles are then reversed, and finally all members discuss their reactions to the experience.
