Tips for Implementation

Question 1

Social proof

Answer 1

Remember to:
* Consider heterogeneous effects in population sub-groups
* Consider risks of backlash
- Is the sender considered trustworthy by the treatment group?
- Will the treatment group be annoyed by the nudge?

Is it more or less difficult to implement than other nudges?
* Norm nudging is NOT subtle
* Norm nudging addresses fundamental human emotions, so one needs to consider the ethics
* → Thus, we recommend careful consideration before implementing norm nudging

Question 2

Tips for implementation of commitment devices and implementation intentions

Answer 2

● Tailoring the nudge to the context
○ The more specific the implementation intention (e.g., specifying when and where an action will occur), the more likely it
is to lead to behavior change.

● Consider behavioral biases
○ Commitment devices are especially useful for people who struggle with present bias, where immediate temptations undermine long-term goals.
○ For effective implementation, designers should ensure the commitment penalty is sufficiently motivating but not overly harsh.

● Tailored to behavior type
○ Implementation intentions are more effective for one-time actions (e.g., vaccinations, voting) than for repeated
behaviors (e.g., regular exercise)

● Monitor and adapt the design
○ One major challenge is that many participants fail to follow through on their commitments
■ Periodic reminders, follow-up prompts, or adjustable goals can help sustain long-term commitment.
