Progress to date has varied between different sub-disciplines and this final chapter will touch on common themes throughout. Psychology as a discipline has much to gain from the digital age, especially following the mass adoption of smartphohes. Software development is an entire discipline within itself, but even comparatively simple smartphone apps that collect minimal data can be highly revealing of everyday behaviour. However, we face numerous challenges that go beyond technological development. Some of these issues pretain to theorising and replication, while others concern the scientific climate in which we operate. Most of these issues are not unique to research involving new technology, but they become more apparent as the speed of innovation accelerates. As a result, we appear to carry very little understanding forward to the next mass-adopted innovation.

By reflecting on past successes and failures, this chapter provides guidance on how psychological research can become more productive and break free from tired cycles of research. More importantly, if psychological science can re-align existing priorities and embrace the digital age, it has nothing to lose and everything to gain.
