This commentary takes up the notion proposed by Lewis-Fernández and colleagues that we need more balance in research priorities. Specifically, our reliance on neurobiology may be misplaced and likely to be unrewarding unless we ensure that: (a) research with better return for patients and the public is also pursued; (b) research findings are put into practice; and (c) we retain a focus on proportionate investment in service provision. Patient, public and economic perspectives should drive the decision making for better investment, and behaviour change might be better targeted at commissioners and policy makers rather than patients and providers.
