The Four Elements of the Friendship Formula
Dr. Jack Schafer explains the four components that build any personal relationship: proximity, frequency, duration, and intensity. These elements, developed from his FBI work recruiting spies, can be applied to everyday relationships to naturally foster connection without forced effort.
- Proximity: Being in the same space establishes initial awareness and mutual liking.
- Frequency: Repeated exposure strengthens the bond over time.
- Duration: Spending sustained time together deepens the relationship.
- Intensity: Nonverbal cues like eye gaze and vulnerability turn casual contact into meaningful connection.
“The friendship formula basically has four elements: proximity, frequency, duration, and intensity.”
