How To Spot Autism In High-Masking Adults

Dr. Luke Beardon is a leading autism researcher, author and senior lecturer at Sheffield Hallam University who has spent more than 30 years working alongside autistic people and their families. In this episode, Luke reveals what autism can actually feel like from the inside, from masking and rehearsing conversations to sensory overwhelm, burnout and the exhaustion of constantly trying to fit in. He explores why so many people go decades without realising they’re autistic, what happens when you mask for so long that you lose sight of who you really are, and why the parts of yourself you spent a lifetime hiding may never have needed fixing in the first place.

WHAT IT’S REALLY ABOUT

Understanding high-masking autism in adults: signs, costs, and unmasking

  1. Autism is often missed in adults due to historical diagnostic blind spots, limited past awareness in schools, and present-day barriers like long assessment waiting lists.
  2. High-masking autism is less about visible traits and more about sustained, effortful, conscious (or habitual) coping that drains energy and increases anxiety.
  3. Many autistic traits are misread as personality flaws (e.g., being ‘too direct’ or ‘pedantic’), creating shame, guilt, and pressure to suppress self-regulating behaviors like stimming.
  4. Sensory overwhelm is framed as a neurological filtering difference that can flood conscious processing, contributing to shutdown, distress, or the need for recovery after social exposure.
  5. Long-term masking can contribute to identity loss, burnout, physical and mental health issues, and increased trauma risk, while selective unmasking in safe contexts can improve wellbeing.

IDEAS WORTH REMEMBERING

5 ideas

You can’t ‘look autistic,’ and expecting a look harms high-maskers.

Beardon argues the idea that autism has a visible presentation is illogical and fuels accusations that masked adults are exaggerating or ‘making it up,’ undermining self-trust and help-seeking.

Masking in autism is defined by effort, awareness, and exhaustion—not social politeness.

He distinguishes everyday adaptation from autistic masking by asking whether the person is constantly aware of performing, expending huge effort, and needing significant recovery afterward.

Masking often begins in childhood because conformity is rewarded and difference is punished.

Examples like school reward charts for “good sitting” teach very young children that authenticity is unacceptable, pushing them to suppress needs and adopt neuronormative behavior patterns.

Rehearsing conversations is a safety strategy to prevent social ‘misfires.’

Autistic people may script or mentally pre-check language because subtle differences in communication norms can lead to being judged, spotlighted, or shamed, which increases anxiety.

Small talk can be exhausting because it prioritizes bonding rituals over information and clarity.

Beardon frames this as a mismatch of social languages: autistic people may find small talk illogical or risky, and he challenges the idea that autistic people lack “social skills” (it’s often neurotypical social skills being demanded).

WORDS WORTH SAVING

5 quotes

The misconception is in the question that you've asked, in that it looks like anything at all. You can't look at somebody and tell them that they're autistic, otherwise we would all know who the autistic people are.

Dr. Luke Beardon

You're not good enough being your own authentic self. We need you to change and conform, i.e. mask, in order to suit everybody else.

Dr. Luke Beardon

Show me a non-autistic person who's good at being autistic. They don't exist either.

Dr. Luke Beardon

Well, I don't wanna be too bleak, but it can cost you your life, um, I suspect.

Dr. Luke Beardon

I know you're exhausted, not because you're being yourself, but because you're trying so hard not to be.
