The research, published in the Journal of Social and Personal Relationships by Jeewon Oh and colleagues, followed 226 newlywed couples across three waves of data over roughly three to four years. The headline is reassuring: people were generally accurate at tracking their partner's attachment patterns over time. We do read each other, and we read each other fairly well.
But sitting on top of that accuracy was a consistent tilt. People overestimated how anxious and how avoidant their partner was — reading more insecurity into her than she reported feeling herself. Part of where that tilt came from was projection: when you feel anxious, you tend to assume your partner does too; when you feel distant, you read her as pulling away. Some of the "her" you see is quietly your own feelings, borrowed.
There's a nuance worth stating carefully, because it cuts both ways. People who were happier in their relationship tended to see their partner as less insecure overall — a slightly rosy lens. And the flip side: the more stressed or insecure you feel, the more you may read your partner as anxious or withdrawing. The lens moves with your own state, not just hers.
What it means for you: If it feels like your partner has gone cold or distant since the baby, that reading isn't neutral data — it's filtered through how depleted you are right now. Post-baby stress can make you misread her as colder and more distant than she actually is. Before you conclude something's wrong between you two, the first question worth asking is: am I bringing my own anxiety to how I'm reading her?

The finding was also covered by PsyPost.
Frequently asked questions
Do people accurately judge their partner's attachment style?
Fairly well. Across 226 newlywed couples tracked for 3–4 years, people tracked their partner's attachment patterns with real accuracy — but alongside that accuracy sat a steady bias to see the partner as more insecure than she reported being.
What did the study find about bias?
People consistently overestimated how anxious and avoidant their partner was. Part of that came from projection — reading their own anxiety or distance onto their partner rather than seeing hers clearly.
Does being happy in the relationship change how you see your partner?
It seems to. People who were happier in their relationship tended to see their partner as less insecure overall — a slightly rosy lens. The more stressed or insecure you feel, the more you may read your partner as pulling away.
Why does this matter for new parents?
Post-baby stress can tilt the lens. When you are exhausted and on edge, you are more likely to read your partner as colder or more distant than she actually is — so it is worth checking whether the distance is hers or your own fear talking.
