Choice architecture as defined by Professor Mormann in Climate Choice Architecture is helpful and important, but it is also easy to overestimate its impact. It is not everything. This Comment argues that choice architecture is framing a decision at the point of decisionmaking, presenting a list in a specific way, like the decoy effect, setting defaults. Sometimes, social norms and feedback is choice architecture if presented at the time of making a decision or if presented at the optimal choice opportunity. But Sussman doesn't typically put these in the choice architecture bucket. There are many other psychology-based approaches and understandings that are important, like reward and punishment.
