The Spark Myth
Pop Psychology
The intensity of early attraction (often limerence) is driven by neurochemistry, particularly dopamine and norepinephrine.
**Reality: Biologically impossible to sustain.** The intensity of early attraction (often limerence) is driven by neurochemistry, particularly dopamine and norepinephrine. The brain literally cannot maintain that state indefinitely. It fades in every relationship, typically within 6 months to 3 years. This is not failure. Long-term love is different — deeper, quieter, more intentional — but not lesser. Expecting permanent butterflies leads people to leave good relationships or chase limerence indefinitely.
Evidence
Pop Psychology
The idea that an instant, intense spark is how you recognize the right person earns Pop Psychology. The implicit-theories research finds that treating a strong initial spark as the test of compatibility goes with more volatile, less durable relationships, because it frames effort and early friction as signs of a mistake (Knee, 1998). Intense early chemistry is real but unreliable as a predictor; it overlaps heavily with infatuation and limerence, which fade. Lasting attraction is better predicted by what partners build than by how loud the opening felt.
