In my work on neurodiversity and conflict, there are some interesting intersections that come up frequently. There’s one phenomenon I want to make sure you understand, because it comes up constantly in conflict situations. It’s called rejection sensitivity, or sometimes rejection sensitive dysphoria.
We all feel rejection
Let’s start with what’s universal.
We all have some sensitivity to rejection. We’re social beings. We want to belong. We want to fit in. We don’t like the feeling of being an outcast, of being excluded, of not being part of the group.
Think about school. There were always the cool kids in the clique. And there were the people who wanted to be part of the cool kids but weren’t quite in. That feeling of being on the outside looking in, most of us know what that’s like. It’s uncomfortable. It hurts.
That’s normal human experience.
Rejection sensitivity
For many neurodivergent people, particularly autistic people and people with ADHD, rejection sensitivity is like that experience on steroids.
It’s not just discomfort at being excluded. It’s an intense, overwhelming emotional response to any perceived rejection, criticism, or failure.
And I want to emphasize that word: perceived. It doesn’t have to be actual rejection. It doesn’t have to be intended criticism. The person’s nervous system responds to what it perceives, and that perception can be triggered by very subtle cues that others wouldn’t even notice.
Where it comes from
This heightened sensitivity is often built up over time. It’s a form of trauma, really.
When you’ve spent your whole life not fitting in, when you’ve struggled constantly, when you’ve felt different from other people and been reminded of that difference repeatedly, your nervous system learns to be on high alert for rejection.
Every social interaction becomes a potential threat. Every conversation carries the risk of another confirmation that you don’t belong, that you’re not good enough, that there’s something wrong with you.
The sensitivity isn’t irrational. It’s a learned response to a lifetime of experiences. The nervous system is trying to protect the person from more pain by detecting threats early.
The problem is that it becomes hypersensitive. It starts detecting threats that aren’t really there.
What it looks like
Someone with rejection sensitivity can have what we might perceive as a gross overreaction to any implied criticism.
You might offer what you consider gentle, constructive feedback. To you, it’s minor. Helpful, even. But to them, it lands like an attack.
You might make a neutral observation that they interpret as criticism. You might ask a clarifying question that they hear as doubt in their competence. You might have a facial expression that they read as disapproval.
And suddenly, they’re having a very big emotional response that seems completely out of proportion to what happened.
The shame response
Here’s what’s really important to understand: the response isn’t just “I made a mistake” or “I could improve.”
It goes straight to shame. To “I’m a bad person.” To “There is something fundamentally wrong with me.”
That’s the difference between guilt and shame. Guilt says, “I did a bad thing.” Shame says, “I am bad.”
For someone with rejection sensitivity, criticism doesn’t just point to behaviour that could be different. It confirms their deepest fear: that they are defective, unacceptable, unworthy of belonging.
That’s why the response is so intense. It’s not about the specific feedback. It’s about what the feedback represents: another piece of evidence that they don’t measure up, that they’ll never be good enough, that they don’t deserve to be included.
The feelings that follow
When rejection sensitivity is triggered, you often see:
Intense embarrassment. Not just mild discomfort, but crushing, overwhelming embarrassment that feels unbearable.
Self-doubt. Questioning everything about themselves. Wondering if they’re capable of anything.
And underneath it all, shame. That deep sense of being fundamentally flawed.
These feelings can persist long after the triggering event. While someone else might shake off a piece of criticism in a few minutes, the person with rejection sensitivity might ruminate on it for days. It confirms their internal narrative about themselves.
Self-protective behaviours
When someone is experiencing this kind of intense emotional response, they often move into self-protective behaviours. And these can be very difficult to manage, especially in a mediation or conflict resolution setting.
It might look like fight. Becoming defensive, argumentative, attacking back. If they can make the other person the problem, they don’t have to sit with the shame of being criticised.
It might look like flight. Shutting down, withdrawing, wanting to leave the room, refusing to engage further. If they can escape the situation, they can escape the unbearable feelings.
It might look like people-pleasing or over-apologising. Desperately trying to repair the relationship, to get back into good standing, to prove they’re not as bad as they fear they are.
It might look like denial or deflection. Refusing to acknowledge the feedback at all, changing the subject, minimising what was said.
All of these are attempts to manage an overwhelming emotional experience. They’re not rational strategies. They’re survival responses.
How this plays out in conflict
You can see how easily this could escalate a conflict situation.
In mediation, we often need to help people hear difficult things. We need to facilitate conversations where feedback is exchanged, where behaviour is discussed, where people acknowledge impact.
For someone with rejection sensitivity, every one of those moments is potentially triggering.
Performance management is another obvious context. The whole point of performance management is to identify areas for improvement. But if any suggestion of improvement is experienced as a fundamental attack on the person’s worth, the conversation becomes almost impossible.
Even something as simple as a misunderstanding can spiral. If someone feels they’ve been misunderstood, and they interpret that as rejection, they can have a trauma response that derails everything.
It’s a trauma response
I want to be clear about this: what we’re describing is a trauma response.
The person isn’t being dramatic. They’re not choosing to overreact. Their nervous system is responding to what it perceives as a genuine threat to their safety, their belonging, their sense of self.
When you understand it as trauma, you respond differently.
You don’t dismiss it. You don’t tell them to calm down. You don’t get frustrated that they’re making a big deal out of nothing.
You recognise that something very real is happening in their body and their brain, even if the trigger seems small to you.
Implications for practice
So what do we do with this?
First, be aware that rejection sensitivity exists and that it may be present in the people you work with. If someone seems to be responding intensely to mild criticism, this might be what’s happening.
Second, be thoughtful about how you deliver feedback or facilitate difficult conversations. This doesn’t mean avoiding hard truths. It means being intentional about framing, about language, about creating safety.
Third, when you see a big reaction, don’t escalate. Give space. Recognise that the person may need time to regulate before they can engage productively.
Fourth, remember that the reaction isn’t really about you or about the specific thing that was said. It’s about a lifetime of experiences that have made this person’s nervous system hypervigilant to rejection.
Fifth, consider how you might help the other parties in a conflict understand what they’re seeing. If one person has a big reaction and the other person thinks they’re being manipulative or unreasonable, that misunderstanding will make everything worse.
Compassion, not frustration
It’s easy to get frustrated when someone seems to overreact. Especially when you’re trying to help. Especially when the feedback was gentle. Especially when you’ve done everything right and they still respond as if you’ve attacked them.
But frustration doesn’t help. It usually makes things worse.
What helps is compassion. Understanding that this person is in pain. That their response, however disproportionate it seems, is real to them. That they’re not trying to be difficult.
That understanding doesn’t mean you accept harmful behaviour. It doesn’t mean you abandon the conversation or avoid all difficult topics. It just means you approach the situation with awareness of what’s actually happening, rather than judgment about what should be happening.
Rejection sensitivity is hard to live with. The people who experience it don’t enjoy it. They often feel ashamed of their reactions, which of course only adds to the shame they’re already carrying.
A little understanding can go a long way.
If this resonates with your practice, my new online course Working with Neurodivergent Clients in Conflict goes deep on exactly these dynamics. Part 1 is now open for beta testing: 10 modules, 3 hours of content, covering everything from the foundations of neurodiversity to emotional experience, sensory processing, masking, and transitions. For a limited time, beta participants access Part 1 at AU$297+GST and receive discounted access to Parts 2, 3 and 4 as they release. This is practical, practitioner-focused training designed to build the kind of fluency that actually changes how you work.
