The Nudge Effect of "Happy to Chat" Badges: Evidence from England

Social connection is essential for well-being, yet people often avoid interacting with strangers due to concerns about conversation quality or a lack of shared interests. This study investigates whether the Happy to Chat badge can act as a behavioural nudge to promote social connectedness. Using a nationally representative online sample of 1,738 adults in England (via YouGov), we tested whether wearing the badge influences perceptions of friendliness, trustworthiness, and interest in conversation, as well as social behaviours such as smiling, eye contact, nodding, and willingness to initiate a chat. Results show that badge wearers are perceived as significantly more friendly, trustworthy, and open to conversation, and are more likely to receive social acknowledgements, although wearing the badge did not significantly increase others' intention to initiate conversation. Age and gender effects were also observed, with older and female targets generally receiving more favourable social responses. These findings suggest that while the badge effectively promotes social recognition, it may be insufficient on its own to overcome deeper psychological barriers to initiating conversations with strangers. This paper confirms the effectiveness of the Happy to Chat badge as a nudge to promote social connectedness within communities and highlights its practical implications.
