The systematic review undertaken for the Group Analytic Community by Sheffield University is an excellent piece of work ‘of its time’, but it may not speak to everybody in the field. Some of the reasons for this are the precise methodology of such reviews, concerned with an exclusively rationalist model for selecting and appraising evidence in a framework, which excludes other schools of thought (particularly the social sciences, including critical theory, anthropology and economics). As many of those who work in group analysis have backgrounds in these and allied disciplines, rather than biomedical science, there is a risk of excluding much useful and scholarly collaboration with adjacent disciplines unless we hold an open mind about such methodologies. As group analysts, we are in a strong position to observe and criticize the ‘evidence-based hegemony’ when it becomes closer to dogma than science.
