Can viral relationship tests like the bird test really tell you about your relationship?

If you have been on TikTok lately, you may have stumbled upon the “bird test”. One partner casually points out something – like a bird outside the window – and waits to see whether the other responds with interest. If they do, the relationship gets a symbolic green flag. If not, trouble may be brewing. It’s funny and relatable, and it’s striking a nerve. Millions of people are now scrutinising tiny interactions, hoping for reassurance that their partner is truly invested. And psychologists like me can see why: this viral test captures something researchers have long known – that love is built in small moments of responsiveness.

For decades, relationship researchers have argued that love lives in these micro-moments. We call these everyday attempts to connect “bids”: a joke shared, a story told, a quick “look at that!” In classic lab-based research with newlywed couples, psychologist John Gottman found that partners who consistently “turn toward” small bids for connection report happier relationships. Other longitudinal studies have found that couples whose early interactions include more positive, engaged responding during conflict are more likely to remain stable and satisfied years later.

Other work underscores that responsiveness in tiny, everyday moments – not just during conflict – predicts relational well-being. A study of newlyweds revealed that couples who show more playfulness and enthusiasm during a 10-minute dinnertime interaction are more likely to use more humour and affection during a conflict discussion. In longitudinal research, people who see their partners as more responsive – attuned, validating and caring – become more physically affectionate over time, a small but potent way couples sustain intimacy in daily life.

Over time, these little acknowledgements form the glue that holds relationships together. In that sense, the bird test is a clever distillation of a deeper truth: small acts of responsiveness matter. They may seem trivial in isolation, but when repeated over time, they create the forward momentum that keeps relationships satisfying and resilient.

But individual moments – especially those filmed for social media – cannot diagnose the health of a relationship. The bird test turns a complex pattern into a one-off pass/fail scenario, which can fuel unnecessary anxiety or false confidence. Partners miss bids all the time for reasons that have nothing to do with commitment: they could be tired, stressed or simply didn’t hear the comment. The danger isn’t the test; it’s what we do with it. If we treat a single moment as a verdict, we risk catastrophising: “They ignored the bird! Do they even love me?” Or worse, weaponising it: “You didn’t respond! You never pay attention to me.” A relationship is not defined by a single reaction on a random Tuesday.

The bigger question is why tests like this have exploded. Alongside the bird test, we have seen the rise of the “orange peel theory” – will your partner peel an orange for you without being asked? – and the “moon phase test”, which claims romantic compatibility based on the alignment of birth-date moon phases.

Part of the answer lies in dating uncertainty. Dating apps present us with seemingly endless options for mates, but research suggests that having so many choices can actually make commitment feel riskier and less secure. That uncertainty spills into how relationships form – more “situationships”, fewer defined expectations and a lot of guessing about how your partner really feels. Viral tests promise quick clarity: one moment, one gesture, one simple answer.

Another reason is that relationship science has gone mainstream but has been stripped of nuance. Research on responsiveness, developed through careful observational studies, gets flattened into TikTok-scripts like: “Did they comment on the bird?” At the same time, social media rewards highly emotional content: the heart-melting or heart-breaking reaction captured on camera. That attention economy encourages people to turn real relationships into public experiments. Viral tests thrive in this environment because they offer a simple, dramatic moment of proof that can be recorded, shared and judged by an audience.

So, what should couples take from all of this? The bird test isn’t nonsense. It captures something vital: being responsive when a partner reaches out, even in tiny ways, is a cornerstone of healthy relationships. If a trend encourages more curiosity, attention and appreciation, I see that as a win. But instead of asking, “Did my partner pass the test?”, better questions are: “What is your partner’s pattern over time? Do they reliably show up for you? Do you feel heard? Valued? Known?” Love is not defined by what someone does with one bird – or one orange – but by the hundreds of small moments in which partners choose to show up for each other when no one is watching.

Still, I’ll admit: I might try the bird test on my husband tonight, purely for science. Wish him luck.
