Design your daily environment to create repeated exposure
You cannot become friends with people you never run into — engineer the run-ins.
Key takeaways
- What it is: You cannot become friends with people you never run into — engineer the run-ins.
- Why it works: The mere exposure effect (Zajonc, 1968) establishes that repeated exposure to a stimulus — including a person — increases liking for it. Propinquity operationalizes this: living near someone creates repeated, passive exposure that the brain processes as familiarity, which it interprets as safety and trust. Because the exposure is passive, it bypasses the social anxiety that active approaches often trigger, allowing liking to build before deliberate effort is required.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Trying to make friends by identifying people you like and then approaching them, without first creating a structure that provides repeated passive exposure — the approach often feels awkward because familiarity hasn't yet built.
Why it works
The mere exposure effect (Zajonc, 1968) establishes that repeated exposure to a stimulus — including a person — increases liking for it. Propinquity operationalizes this: living near someone creates repeated, passive exposure that the brain processes as familiarity, which it interprets as safety and trust. Because the exposure is passive, it bypasses the social anxiety that active approaches often trigger, allowing liking to build before deliberate effort is required.
How to do it
- 1Identify the physical spaces where you want to meet people and arrange to be in those spaces regularly and predictably.
- 2Choose a specific seat, desk, or spot that maximizes the chance of seeing the same people repeatedly rather than rotating through novelty.
- 3When relocating, prioritize proximity to community spaces (parks, markets, gathering spots) over private amenity.
- 4In remote or hybrid work, use synchronous channels (video calls, shared office time) to replicate the passive-exposure function that office proximity used to provide automatically.
What the evidence says
ObservationalFestinger, Schachter, and Back's (1950) Westgate housing study found that the strongest predictor of friendship was the distance between apartment doors and staircase proximity, not shared interests or demographics.
Honest caveat: The Westgate study was conducted in a homogeneous sample (married graduate students); generalization to diverse populations and modern environments involves inference. Digital proximity likely creates some exposure but less reliably than physical.

Common mistake
Trying to make friends by identifying people you like and then approaching them, without first creating a structure that provides repeated passive exposure — the approach often feels awkward because familiarity hasn't yet built.
IX Coach helps you audit your daily environments and identify where redesigning your routine or location choices would create higher-quality repeated exposure to the kinds of people you want to know.
