I agree with the nomenclature point (although behavioural economics is not just about finance: it’s about allocating and trading scarce resources, which could be time, attention, reputation, beliefs, and so on). The name emerged because some economists saw the glaring anomaly in recent neoclassical economics, rather than social psychologists seeing a distinctive subfield around scarce resources. And the rest is history :-)
