The author introduces a psychological game named TAMED – the TA Myth of Explanatory Depth, which she suggests provides an explanation of unhealthy dynamics occurring within transactional analysis membership and professional associations. She illustrates this with four case examples based on personal experiences. She also provides an overview of TA theory about psychological games, the bystander role, the various roles within the drama triangle and extensions of it, and the potency pyramid. She provides a selection of materials by TA and non-TA authors to support the premise that such games are more to do with organisational and group processes than the script of the individual who is seen as the cause of the conflict. The article concludes with some initial thoughts about how TA organisational diagrams need amending to reflect the structure and dynamics of professional associations.
