Mindguard
A mindguard, according to groupthink theory, is a member of a group who serves as an informational filter, providing limited information to the group and, consciously or subconsciously, utilizing a variety of strategies to control dissent and to direct the decision-making process toward a specific, limited range of possibilities.

Multiple mindguards are frequently present in groupthink situations.

• time pressure in regard to decision-making • bandwagon effect/ information cascades • reframing situations to increase pressure toward or away from a specific outcome • creating a sense that group cohesion will suffer if unanimity is lacking • other techniques
