The field of psychology is usually ignored by mainstream economists, which, in its typically arrogant and closed practice, adopts a series of a priori assumptions about human behaviour – the so-called Homo economicus – where were are always rational and self-interested and, as a result, always make choices that maximise our present and future well-being based on available market signals. Real world forces that condition actual human behaviour, such as cognitive biases and irrationality, in general, as well as cooperative and collective behaviour is ignored by mainstream neo-classical (free market) economic theory, because admitting its dominance in human decision-making would void the entire edifice of that theory and scuttle the authority that is given to the on-going narratives about deregulation, small government, privatisation, pernicious cutting of income support, and the rest of the economic policies that have defined this dysfunctional neo-liberal era. But humans do not behave in the way economists suggest. We are a complex mass of irrationality, custom, habit, and affect. We certainly use cognitive processes in our decision making but often we take shortcuts based on affect. These tendencies are pushing our behaviour back to what was normal before the credit binge that led to the GFC. This shift in our behaviour is associated with stagnation and entrenched mass unemployment. But the reason for these parlous outcomes is not that we have returned to more normal spending behaviour but, rather, because governments have not realised that they had to return to more normal behaviour as well. Instead of promoting the benefits of austerity (in the face of all evidence to the contrary), governments should have been promoting the benefits of continuous fiscal deficits to support non-government saving desires and maintain better employment outcomes and stronger income growth. The malaise advanced nations are stuck in at present is directly the result of ideologically-motivated choices made by governments to use to use fiscal policy properly. Neo-liberal ideology remains dominant but citizens are rebelling and something has to give.
