TikTok's Obsession With Relationship Tests
TikTok has spawned dozens of viral relationship "tests" — quick, visual ways to evaluate your partnership. But which ones have any basis in reality? We compared the biggest ones.
1. The Green Line Test
How it works: Draw green lines along each person's spine in a couple photo. Straight = STRONG, leaning = WEAK.
Origin: Rivelino on Twitter (2020), went viral via JackMacBarstool's Kim/Pete TikTok (2022)
What it claims to measure: Relationship power dynamics and emotional dependence
Scientific basis: Minimal. Body language experts like Dr. Lillian Glass have called it "simply not true." However, posture research does show upright stances correlate with confidence. Read our full scientific analysis.
Virality: 500M+ TikTok views under #GreenLineTest
Our verdict: Fun entertainment, zero diagnostic value. The visual format makes it incredibly shareable.
2. The Orange Peel Theory
How it works: Ask your partner to peel an orange for you. Their willingness (and attitude) reveals whether they'll do small acts of service.
Origin: Went viral on TikTok in late 2023 when users shared videos of partners happily (or reluctantly) peeling oranges.
What it claims to measure: Your partner's willingness to do small, unglamorous things for you — a sign of everyday love.
Scientific basis: Moderate. This actually aligns with Dr. John Gottman's research on "bids for connection." Gottman found that successful couples respond positively to small requests 86% of the time, while couples who eventually divorce respond only 33% of the time. Peeling an orange IS a bid.
Virality: 100M+ views
Our verdict: Surprisingly has some merit. Small acts of service are genuinely researched markers of relationship health. But making it a "test" adds pressure that doesn't exist in normal situations.
3. The Bird Test
How it works: Point out a bird (or anything random) and say "look at that bird!" If your partner looks and engages, they're attentive. If they ignore you, they're disconnected.
Origin: TikTok user @alyssacardib, inspired by attachment theory research.
What it claims to measure: Whether your partner is paying attention to you and willing to engage with your interests.
Scientific basis: Strong (relatively speaking). This is essentially a simplified version of Gottman's "bids for connection" research. Partners who "turn toward" bids (engage, respond, show interest) have significantly more satisfying relationships than those who "turn away" (ignore, dismiss).
Virality: 200M+ views
Our verdict: The most scientifically grounded TikTok relationship test. It's not perfect — someone might be distracted, busy, or not hear you — but the underlying principle is backed by decades of research.
4. The Beckham Test
How it works: Based on how Victoria Beckham described greeting David at the airport. Does your partner light up when they see you? Do they rush to greet you?
Origin: Interviews with the Beckhams discussing their relationship habits.
What it claims to measure: Genuine excitement and emotional connection when reuniting.
Scientific basis: Moderate. Research on nonverbal "greeting behavior" shows that couples in satisfying relationships display more enthusiasm during reunions — wider smiles, faster approach, more touch.
Virality: 50M+ views
Our verdict: A sweet concept. The energy someone brings to a reunion does reflect their emotional investment, though a single greeting on a bad day doesn't define your relationship.
5. The Strawberry Test
How it works: Ask your partner to describe how they eat a strawberry. Their description allegedly reveals something about their intimate personality.
Origin: TikTok trend from early 2024.
What it claims to measure: Supposedly reveals how someone approaches intimacy.
Scientific basis: None. Zero. This is cold reading territory — like horoscopes, any description feels applicable if you want it to.
Virality: 80M+ views
Our verdict: Pure entertainment. Enjoy it for laughs, but it reveals nothing real.
6. The Door Test
How it works: From the 1993 film "A Bronx Tale." When you unlock your car door and walk around, does your partner reach over and unlock your door from inside?
Origin: The movie, which popularized it as a test of thoughtfulness.
What it claims to measure: Whether your partner thinks of you when you're not directly in front of them.
Scientific basis: Minimal for the specific act, but the concept of reciprocal thoughtfulness is well-studied. Dr. Gottman calls it "cognitive room for the partner" — keeping your partner in your thoughts.
Virality: 30M+ views (resurges periodically)
Our verdict: Outdated (most cars have key fobs now), but the underlying principle of reciprocal thoughtfulness is valid.

Why We Love Testing Our Relationships
The psychology behind relationship testing is well-studied:
- Uncertainty reduction — we use tests to seek reassurance about ambiguous situations
- Social comparison — seeing other couples' results helps us gauge our own relationship
- Novelty — new perspectives on familiar relationships feel exciting
- Control — tests give us a sense of control over unpredictable emotional situations
Dr. Rachel Cavallaro, a psychologist, notes that while these tests can be harmless fun, relying on them as diagnostic tools "assumes a lot and doesn't account for the complexity of human relationships."
The Healthier Alternative
Instead of TikTok tests, relationship researchers recommend:
- Direct communication — talk to your partner about your needs
- The Gottman "State of the Union" meeting — weekly check-ins about relationship satisfaction
- Observing patterns over time — not single moments captured in photos or videos
- Professional guidance — if you're concerned, a couples therapist provides more insight than any viral test
