Many academic groups have troubles inside them. They are not related to human relations after establishments, though they have already been originated in the beginning of recruit of members. Chairs are always expected to make a large number of constituents for group establishment by their boss or bosses in academic societies. Less experienced chairs rush into headhunt and solicit friends of friends of friends. The groups that they organize become something odd to the chairs themselves. Most of the members of their groups are not friends of theirs or even worse, not acquaintances. What shall comes to the groups. Some groups become inactive after a while. Others begin to quarrel. The worst ones lose the chairs, who disappear. I don't blame the chairs or the members. It is really difficult to organize non-profit organs; you don't need to read Peter Drucker's on that point. This is common sense. What kind of non-profit organization flourishes in human history? Church, Buddhist temples, synagogues, what else? Schools and universities are actually profit-oriented organizations. Academic societies also belong to the latter. You need not only some causes but also profits to be organized into some groups. For group chairs, it is very difficult to create the profits from their organizations. Probably, internal information that be shared inside groups might be an answer to the question.
