These 3 Words DOUBLE Energy-Saving Sign Ups • Dr Mona Bielig PhD Ep89

Why did this psychology technique get more sign-ups than offering people to save money? In this episode, environmental psychologist Dr. Mona Bielig shares the results of a real-world field experiment that tested one of the simplest—and most effective—behaviour change techniques available.

Working with social housing residents in Belgium, her team discovered that a small change in how an energy-saving technology was described dramatically increased adoption, even though the technology was already free and saved people money.

Katie and Mona unpack the hidden psychology behind social norms, why information and financial incentives are often not enough to change behaviour, and how understanding people's real barriers can transform the effectiveness of climate campaigns.
