Extend kindness toward strangers, not just your inner circle
Acts of kindness toward strangers often produce stronger well-being benefits than acts toward people you already help routinely.
Key takeaways
- What it is: Acts of kindness toward strangers often produce stronger well-being benefits than acts toward people you already help routinely.
- Why it works: Kindness within close relationships can blend into the background of relational obligation, reducing its novelty and hence its emotional salience. Acts toward strangers are more clearly chosen freely, more novel each time, and activate a sense of social connectedness — the feeling that the world is populated by people who can be trusted — which is independently predictive of well-being.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Restricting all kindness to established relationships, where it becomes part of ordinary obligation management rather than a freely chosen prosocial act.
Why it works
Kindness within close relationships can blend into the background of relational obligation, reducing its novelty and hence its emotional salience. Acts toward strangers are more clearly chosen freely, more novel each time, and activate a sense of social connectedness — the feeling that the world is populated by people who can be trusted — which is independently predictive of well-being.
How to do it
- 1On your kindness day, designate at least one act for someone you have no ongoing relationship with.
- 2Keep it simple: pay for a coffee, compliment a stranger genuinely, give directions with real attention, tip generously.
- 3Notice the quality of the interaction and any feelings of connection that arise.
What the evidence says
RCT / meta-analysisResearch by Dunn and colleagues found that spending money on others produced higher well-being than spending on oneself, and that giving to strangers was at least as rewarding as giving to people one knew personally.
Honest caveat: The prosocial spending study measured spending, not behavioral acts specifically; the stranger effect generalizes logically but has not been directly tested in a non-spending context.

Common mistake
Restricting all kindness to established relationships, where it becomes part of ordinary obligation management rather than a freely chosen prosocial act.
