Regular readers will know that I have spent quite a lot of time reading the literature in social psychology trying to understand how groups of scholars become crippled with the patterned behaviour that Irving Janis identified as Groupthink in his ground breaking study published in 1972. I feel that my own profession is dominated by this catastrophic syndrome, which has biased the policy scene towards destructive outcomes. However, even after some major calamities, which the mainstream economists were blind too (such as the GFC), the Groupthink is so entrenched and powerful that academic economists actively engage in purges of what they consider to be ‘fringe ideas’, which they dismiss as the equivalent of homeopathy (that is, witchcraft in their eyes). I read an example of this behaviour this week which indicates to me that we are a long way from seeing fundamental change in the academy which might restore the credibility of my profession in the public milieu. My advice to parents – keep your children away from studying economics!
