If behavioural economics is at the frontier, it seems hard to me to say whether, on average, they’re rather on the psychology or economics side.
In any case, it seems great to me to see that both sciences little by little more inspired by each other. 
Nice article Adam, thanks for sharing.

In a series of articles starting here on Medium, I’m trying to perform kind of a introspective work about what economists are and what they are good at. relationship with other social sciences is clearly one of the topics and I’ll hope you’ll enjoy reading.

Best regards
