September 6, 2026: Relationship Studies Worth Knowing
This week's roundup covers seven peer-reviewed studies. Six were published from August 28 through September 3, 2026. One older study is included because new coverage on August 31 brought it back into the public conversation.
I chose studies that address questions people have asked me about their relationships. I also included the limits of each study so you can see what the researchers found and what the research can't tell us.
Someone not answering you doesn't tell us why that's happening
In three U.S. studies involving 1,146 participants, researchers looked at what happens when one person stops responding and the other person has to interpret the silence.
People who had been ghosted underestimated how bad the other person felt about failing to reply. That gap was larger when the silence wasn't intentional. In the study that included a live interaction, a short reply reduced the misunderstanding.
Silence confirms that someone isn't communicating. In and of itself, it doesn't give you the reason why they're not communicating.
Someone may have lost interest. Someone may be avoiding an uncomfortable conversation. A person who let a message sit too long may also feel increasingly embarrassed about answering. However, each of these hypotheses need information people normally don't have when there's a non-response.
If you've been ghosted, write down what you know before deciding what the silence means.
For example:
What happened?
They haven't answered my last two messages.
What don't I know?
Why they haven't answered.
If you're the person who has delayed responding, you don't need a perfect explanation in order to answer. A short message is better than the uncertainty of silence.
Where the research stops
The researchers couldn't fully recreate naturally occurring ghosting. Much of the research involved early or relatively low-stakes interactions.
These findings also don't tell us how to interpret someone who repeatedly disappears in an established relationship. Repeated avoidance should be evaluated over time.
When money is stressful, what kind of conversation you're having
A seven-day study followed 84 unmarried U.S. couples. Both partners reported their financial stress and relationship stress each day. They also reported how they responded to each other.
When one person reported more financial stress, relationship stress also tended to be higher. Their partner could experience more relationship stress, too.
That connection was weaker when partners reported more support and reassurance.
Going immediately to problem-solving didn't show the same pattern. In some analyses, it appeared alongside more financial stress spilling into the relationship.
Ask:
Do you want me to listen, or help make a plan?
If the answer is "listen," you can hear what's happening before jumping to problem-solving.
If the answer is "make a plan," then you know you're both having the same conversation.
Where the research stops
The study included 84 unmarried couples and followed them for one week.
The researchers measured what people reported about their stress and their partners' responses. They didn't assign some couples to provide reassurance and others to solve problems.
So the study can't tell us that reassurance caused lower relationship stress.
Childhood can help explain where a pattern started, not predict how quickly someone can improve
Researchers followed 411 U.S. couples receiving couples therapy. Participants reported adverse experiences from childhood when they entered the study. Researchers then measured difficulties managing emotions four times through the twelfth session.
Some childhood experiences were connected with greater difficulty at the beginning. People who reported more emotional neglect in childhood also showed faster improvement across the 12 sessions.
That finding doesn't make emotional neglect beneficial. In this group, having more difficulty at the beginning didn't automatically mean improving more slowly.
Ask:
What is different in my life now from when I learned this?
You may have communication skills you didn't have then. You may also have relationships where speaking up carries fewer consequences than it once did.
Where the research stops
Participants reported their childhood experiences from memory. Most participants were White, and relatively few reported very high levels of childhood adversity.
The researchers also couldn't isolate how much of the improvement came from therapy itself. They didn't determine how one partner's childhood experiences affected the other partner's progress.
What one parent learns about conflict may show up in what a child sees at home
A randomized study examined the MotherWise relationship-education program. Researchers assigned 512 perinatal participants to the program and 437 to a group that didn't receive it.
The program taught relationship skills to individuals rather than requiring both partners to participate. After 12 months, participants who completed the program reported better conflict-management skills and stronger disapproval of relationship violence. Those reports were connected with fewer child behavior problems measured later.
The researchers found that attitudes toward relationship violence were part of the statistical path connecting the program with both child outcomes they examined.
A practical question for parents follows from what the researchers measured:
What does my child repeatedly see when disagreement starts?
Where the research stops
The study didn't find a direct program effect on children's behavior in an earlier analysis.
Researchers also didn't directly measure how much conflict each child witnessed. The study, therefore, can't establish that changes in a parent's conflict behavior caused the later differences in child behavior.
Participants were largely low-income Hispanic or Latina women during the perinatal period, which also affects how broadly these results should be applied.
Being an only child doesn't tell you how empathetic someone is
A review of sibling relationships and empathy included 26 samples with 6,665 participants. Researchers also reviewed nine qualitative studies involving another 101 people.
People who reported better relationships with their siblings also tended to report greater empathy. Only children did not differ from people with siblings in overall empathy. Having a sibling with an illness or disability had a smaller relationship with empathy than the quality of the sibling relationship itself.
So if you find yourself explaining someone's behavior by saying, "They're an only child," look at the person's behavior. Watch what happens when somebody else needs something that interrupts their plans. Those behaviors tell you considerably more about how the person handles other people's needs than their sibling status does.
Where the research stops
The studies used different measures and included people across a wide age range.
Much of the research measured sibling relationships and empathy at the same point in time. Researchers can't say that having a good sibling relationship caused someone to become more empathetic. It's also possible that people who are already more empathetic build better relationships with their siblings.
Before a conversation about race, know what you want from the conversation
Two studies examined what people wanted from conversations about race with friends.
One study compared LatinX and White participants. The other compared Black and White participants.
Participants reported a stronger desire for social connection when thinking about conversations with racially minoritized friends than when thinking about conversations with White friends. White participants also reported stronger learning goals when the friend was LatinX or Black. Their goals changed more depending on the friend's race.
That means two conversations about the same subject can begin with different intentions. Before you start one, ask:
What do I want to be different between us after this conversation?
Then ask:
What could I hear that would make me reconsider something I currently believe?
Where the research stops
The researchers asked participants to report their goals. They didn't observe the conversations themselves. They also didn't test whether particular goals produced closer friendships or better conversations.
The publisher's public information doesn't provide the exact sample sizes, so these findings shouldn't be used to estimate how common any of these goals are.
If being single feels like waiting, choose something you don't need a relationship to do
A three-study article involving 600 adults examined how people experienced singlehood. The research was first published on August 6 and received new attention after The Washington Post covered it on August 31.
People who saw being single as a period when they could grow reported more experiences that introduced them to new activities or interests. They also reported greater satisfaction with their lives. In the weekly study, 83% of those experiences involved another person, usually a friend or relative.
The researchers also ran an experiment that asked participants to imagine new activities they could do in the future. This increased positive mood in the moment. It didn't change how participants thought about singlehood more broadly.
Ask:
What is one thing I want to do this week that doesn't require a romantic relationship?
Where the research stops
Most participants were young adults. Several of the relationships researchers found were strongest when people's beliefs and experiences were measured during the same day or week. Some became weaker over longer periods.
The experiment improved mood in the moment; it didn't change participants' overall beliefs about singlehood. So, this research can't tell us that deciding to "think positively" about being single will produce lasting changes in well-being.
What I'd take from these seven studies
The question I keep coming back to is:
What happened, and what are we assuming it means?
