BiggDate vs Boo
Both use psychology, but different psychology.
BiggDate and Boo both use a psychological lens for matching, but the lens is different. Boo matches on MBTI personality types — Introvert/Extravert, Thinking/Feeling, etc. BiggDate matches on attachment style, conflict pattern, and love languages, derived from a directed conversation rather than a self-reported quiz. Attachment theory has stronger empirical support than MBTI for predicting relationship outcomes.

Questions about this comparison
Is attachment theory better than MBTI for matching?
Empirically, yes — for predicting relationship outcomes. MBTI has well-documented test-retest reliability problems and weak predictive validity for relationship satisfaction. Adult attachment theory has decades of research showing meaningful predictive power for conflict patterns, satisfaction, and stability.
Why does BiggDate use a conversation instead of a quiz?
Self-reported quizzes are noisy. People answer how they want to be, not how they are, and the same person can score differently on consecutive days. A directed conversation with adaptive follow-ups extracts more reliable signal because the inference is on actual descriptions of behavior, not self-categorization.
