Groupthink arises when the members of a group seek to minimise conflict by failing to critically test, analyse, and evaluate the ideas that are put to them as a group. As a result, the decisions reached by the group are hasty and irrational, and more unsound than if they had been taken by either member of the group alone. Even married couples can fall into groupthink, for example, when they decide to take their holidays in places that neither spouse wanted, but thought that the other wanted.

Groupthink principally arises from the fear of being criticised, the fear of upsetting the group, and the hubristic sense of invulnerability that comes from being in a group. The 20th century philosopher Ludwig Wittgenstein once remarked that ‘it is a good thing that I did not let myself be influenced’. In a similar vein, the 18th century historian Edward Gibbon wrote that ‘…solitude is the school of genius … and the uniformity of a work denotes the hand of a single artist’.

In contrast to Wittgenstein or Gibbon, modern society constantly reinforces the notions that man is a social animal, that he needs the companionship and affection of other human beings from cradle to grave, and that the chief source of his happiness should come mostly if not exclusively from intimate relationships with other similarly gregarious human beings. In the realm of the nine to five or eight to eight, large corporations glorify and reinforce conformism, decisions are taken by committees dominated by groupthink, people are evaluated according to their ‘team playing skills’, and any measly time out is seen as an opportunity for ‘team building’, ‘group bonding’, ‘networking’, or, at best, ‘family time’.

Yet solitude also has an important role to play in any human life, and the capacity and ability for solitude are a pre-requisite for individuation and self-realisation. In his book of 1988, Solitude – A Return to the Self, the psychiatrist Anthony Storr convincingly argues that ‘the happiest lives are probably those in which neither interpersonal relationships nor impersonal interests are idealised as the only way to salvation. The desire and pursuit of the whole must comprehend both aspects of human nature.’
