{{Main|Wilfred Bion}}
Wilfred Bion (1961) studied group dynamics from a [[psychoanalysis|psychoanalytic]] perspective, and stated that he was much influenced by [[Wilfred Trotter]] for whom he worked at [[University College Hospital]] London, as did another key figure in the Psychoanalytic movement, [[Ernest Jones]]. He discovered several mass group processes which involved the group as a whole adopting an orientation which, in his opinion, interfered with the ability of a group to accomplish the work it was nominally engaged in.<ref>Page 194 to 196, Irvin D.

The [[Tavistock Institute]] has further developed and applied the theory and practices developed by Bion.
