Adult Sibling Relationships: The Golden Child & Scapegoat Dynamic

by Dr. Marc J. Shulman | Long Island Psychology | Family Relationships, Nassau County | Page last updated: September 2026

Across Long Island families, the quiet disappointment of a sibling relationship that never became a friendship shows up at nearly every holiday table in Nassau County.
Here’s a question worth sitting with honestly: if this person weren’t your sibling, would you choose them as a friend?

Reach out to Long Island Psychology

Most people have never let themselves ask it, because the assumption underneath sibling relationships runs deep enough that it rarely gets examined at all. You’re closely related, so you must be close. When the honest answer is yes, that’s wonderful; you have a real friendship, built on a shared history nobody else has access to, and it deserves investment. When the answer is no, the whole equation changes, and pretending otherwise is usually where the frustration in adult sibling relationships actually begins.

Reach out to Long Island Psychology to build a sibling relationship that fits what it actually is. No pressure, just a conversation.

Why Siblings Don’t Automatically Become Friends

Ideally, siblings grow into a real friendship in adulthood: genuine love and support that no longer needs a shared roof to hold it together. That happens often, and it can be one of the most satisfying relationships in a person’s life. It doesn’t happen automatically, though, and it certainly doesn’t happen just because two people share parents. When it doesn’t work out, the frustration tends to be sharpest with a difficult sibling, or one carrying their own mental health struggles that shaped how they showed up in the relationship for years.

The common mistake is treating closeness with a sibling as an obligation rather than an outcome, something that must exist because of the biological connection. Test that assumption against the friendship question and the truth gets much easier to see. Once you do see it, forcing a full friendship that was never there stops making sense. It also stops being quite so exhausting.

The Golden Child and the Scapegoat

One of the more common reasons siblings end up on such different footing as adults has less to do with anything between them, and more to do with how a difficult household sorted them into fixed roles in the first place. In families organized around a narcissistic or emotionally immature parent, siblings frequently get split: one idealized, one blamed. Both roles cause real damage, just in different shapes.

The “golden child” often carries a sense of self-worth that’s entirely performance-based. Valued for achievement rather than for who they are, which sets up its own quiet anxiety about ever falling short. The “scapegoat” carries the opposite: a baseline sense of being the problem, absorbed so early that it can resurface in adulthood as depression, or as a self-esteem issue with no obvious present-day cause, long after the household that assigned the role is gone. Family researchers study this under the term sibling deidentification, and it’s well documented. Siblings raised in the same house frequently develop in opposite directions, precisely because a family only had room for one child to occupy a given role; the other adapted by becoming something different, whether or not that difference actually fit who they were.

If you and a sibling ended up in fixed, opposite roles like this, it isn’t surprising that a true friendship never quite formed. In an important sense, you were raised to be different people relative to each other. An honest recognition of that history is more useful than continuing to expect a closeness the family structure itself made unlikely.

What Changes Once You Stop Assuming Automatic Closeness

The relief in this work usually has nothing to do with the sibling relationship suddenly becoming a friendship. What changes is the requirement. Once you can see clearly that the relationship rests on a shared family connection rather than a chosen friendship, you can build something realistic on that foundation: real care, real loyalty, appropriate to what it is, instead of a constant low-grade disappointment measured against something that isn’t there.

That’s not giving up on the relationship. It’s aiming at the right target. Plenty of adult siblings find they can maintain a genuinely satisfying connection, showing up for family events, checking in during hard times, sharing memories nobody else on earth has, without needing to talk every week or share values the way a close friend would.

When the Relationship Has Become Toxic

Sometimes the honest answer goes further than “we’re not close friends.” The relationship is actively harmful: ongoing conflict, criticism, or difficulty that doesn’t ease no matter how the expectations get adjusted. In that situation the same two options apply here as with a difficult parent.

Set clear, firm boundaries that protect your own needs; or, if that isn’t feasible, step back from the relationship, for a period or longer, until the benefits of staying connected genuinely outweigh the cost. Both are legitimate. Neither requires you to have first “tried everything,” whatever family pressure might imply.

What This Looks Like in a Session

A composite of a pattern that comes up often: someone describes years of hurt feelings after every family gathering, because a sibling never calls just to check in, never remembers a birthday, never initiates anything. This same person calls two close friends every week without thinking about it. When we ask directly whether they’d have chosen this sibling as a friend had they met as adults, with no family connection at all, there’s usually a long pause. Then an honest, slightly startled “no.”

That single moment of honesty tends to do more for the hurt feelings than years of trying to explain them away, because the hurt was never really about the missed calls. It was about expecting a friendship from a relationship that was never built to produce one.

What Changes

Before

  • You measure your sibling relationship against a close friendship and feel let down
  • Family gatherings mean re-living old golden-child/scapegoat roles
  • You keep trying to manufacture a friendship that was never actually there
  • Conflict with a toxic sibling gets absorbed indefinitely

After

  • You measure it against what it actually is, and can appreciate what’s genuinely there
  • You can see the old role clearly enough that it stops running the interaction
  • You maintain a real connection, sized to what the relationship actually is
  • You have clear boundaries, or distance, that protect your own wellbeing

If a sibling relationship has never become the friendship you expected, it helps to talk through what a realistic version of it could look like.

How We Treat This at Long Island Psychology

Psychodynamic Therapy

This work looks at the roles your family assigned each sibling growing up, and at how much of the current relationship is still running on those old assignments rather than on who you and your sibling are today.

Dynamic Experiential Learning (DEL)

Developed here at Long Island Psychology by Dr. Shulman, DEL addresses the felt disappointment and the old family-role dynamics directly, rather than only discussing them intellectually.

Cognitive Behavioral Therapy (CBT)

CBT helps identify the specific expectation driving the hurt (“siblings are supposed to be close”) and tests it against your actual relationship, so disappointment stops compounding automatically.

Acceptance and Commitment Therapy (ACT)

ACT helps you invest in the relationships available to you, sibling or otherwise, rather than continuing to grieve a friendship that was never there.

Positive Psychology

This work builds appreciation for what a family-based, non-friendship sibling relationship can genuinely offer, instead of measuring it only by what it lacks.

If you recognize the scapegoat role from your own childhood, this pattern connects closely with our self-esteem therapy work. If you recognize the golden child role, it often overlaps with the perfectionism we treat as part of our high-functioning anxiety work. It also connects to our page on growing up with a narcissistic or emotionally immature parent, since sibling roles like these are usually assigned by the same household dynamic.

We work with adult siblings across Nassau County, Garden City, Rockville Centre, Great Neck, Manhasset, Syosset, Mineola, and Merrick among them, in person and by telehealth. Plenty of the siblings we see grew up a short drive from Jones Beach or caught the same LIRR platform in Merrick every morning for school, proof that shared geography never guaranteed shared closeness. See our full service area here.

What to Expect in Your First Session

We spend the first session mapping the roles your family assigned each sibling growing up, and what a realistic, appropriately scoped version of this relationship could look like for you now. From there, we build a plan out of the mix of psychodynamic, DEL, CBT, ACT, and positive psychology work that fits your particular family history.

Frequently Asked Questions

Is it wrong to admit I wouldn't choose my sibling as a friend?

No. It’s an honest observation rather than a moral failing, and it’s often the first step toward a relationship that actually works instead of one built on a fiction.

Does this mean I should give up on the relationship?

Not necessarily. It means adjusting what you’re aiming for: a real, appropriately scoped family connection rather than a friendship-level closeness that isn’t there. Plenty of people find that adjustment brings them closer, not farther, once the pressure of forcing something else is gone.

What if my sibling was the "golden child" and I was clearly the "scapegoat"?

That’s an extremely common version of this pattern, and it’s worth working through directly: both the impact of the role you were assigned, and how it’s still shaping the relationship (and your own self-esteem) today.

Can two siblings from the same toxic household have completely different experiences of it?

Yes, routinely. That’s often exactly what the golden child/scapegoat split produces, and it’s part of why siblings from the same house sometimes can’t even agree on what their childhood was like.

Should I confront my sibling about the roles we were assigned?

Sometimes that conversation is useful; sometimes it isn’t. It depends on whether your sibling has the capacity to hear it. Meaningful change here often doesn’t require your sibling’s agreement or participation at all.

Does this pattern apply to half-siblings and step-siblings, or only to full biological siblings?

The same dynamics apply regardless of biological relationship. A blended family can assign golden-child and scapegoat roles just as readily as a biological one, sometimes along the lines of which children are whose, which adds its own layer to work through.

I'm realizing I was probably the golden child, and I'm starting to see the damage it caused my sibling. What do I do with that?

That recognition is genuinely useful, and it’s more common than people expect once they start looking honestly. It doesn’t require you to take on guilt for a role you didn’t choose as a child; it can, though, open the door to a more honest, more equal relationship with your sibling now.

Can the golden child and scapegoat roles shift over time, or do they stay fixed for life?

They can shift, particularly around major life events, a parent’s decline, a sibling’s own success or crisis, though the underlying assumptions often linger even after the practical roles have changed.

Is it possible to have a great relationship with one sibling and a genuinely difficult one with another from the same household?

Very possible, and quite common. Siblings from the same family frequently occupied different roles and had different relationships with the same parent, which can produce very different adult outcomes even within one household.

Should I tell my sibling directly that I've realized we were never actually close?

It depends on what you’re hoping the conversation will accomplish. Some people find real relief in naming it; others find more relief in simply adjusting their own expectations quietly, without needing their sibling’s agreement on the assessment.

Does having children of my own change how I feel about my sibling relationship?

Often, yes. Becoming a parent tends to bring old family dynamics into sharper focus, and watching your own kids interact can highlight, by contrast, just how uneven your own sibling relationship actually was growing up.
