Masking and burnout: what the assessment often misses

The findings. Camouflaging is associated with higher measured ability, later or missed diagnosis, and worse mental-health outcomes (Hull and colleagues, 2017; Livingston and colleagues, 2019). Sustained mismatch between expectation and support is a route to autistic burnout, distinct from ordinary occupational burnout (Raymaker and colleagues, 2020).

Why masking correlates with ability

People who can construct plausible neurotypical presentations are, on average, cognitively resourced enough to do so. The presentation is not free; it is a load carried alongside every other task. That is why the correlation with measured ability exists. People who cannot mask fail to mask conspicuously and get flagged. People who can mask succeed at masking conspicuously and get missed.

Why the inference goes wrong

An institution observing high-quality output from someone who is masking sees the output and does not see the load. It infers that no accommodation is required. This is the Capability-Adjustment Fallacy. It is unsafe because it uses evidence that is a product of the accommodation being provided by the person themselves at cost, and concludes that no accommodation should be required. The evidence is present because the person is subsidising the institution's absent adjustment.

The burnout endpoint

Raymaker and colleagues (2020) described autistic burnout as a distinct clinical picture: chronic exhaustion, skill loss, reduced tolerance for previously tolerable stimuli, and functional collapse in domains that were previously accessible. The distinguishing feature from ordinary occupational burnout is skill loss. A masked adult in burnout can lose the ability to do things they were previously able to do, sometimes for months. The literature is clear that this is not a motivational failure.

What clinicians know

NICE CG142 already directs professionals to recognise the discrepancy between intellectual functioning and adaptive functioning. DSM-5-TR records that autistic difficulties can be masked by learned strategies in later life, so high apparent functioning can conceal, rather than refute, support needs. The executive-function literature shows that differences are real but domain-specific rather than globally uniform (Hill, 2004; Demetriou and colleagues, 2018). Everyday dysexecutive difficulty can coexist with intact laboratory task performance.

What institutions do not

Employment and legal frameworks tend to work on cross-sectional evidence: a snapshot of ability at the moment of assessment. Masking is invisible in a snapshot. It is visible only when someone stops masking or when the load exhausts them. Institutions that assess on snapshots systematically miss the burnout trajectory until it has already happened, at which point the person is often no longer able to advocate for the adjustment they should have received.

What the reader keeps

Masking is a load that produces the very evidence that gets used to withhold accommodations from the person carrying it. That is not an accusation of bad faith. It is a description of an inference pattern that clinical guidance already contradicts. Institutions that want to comply with the Equality Act sections 20 and 149(6), and the Practice Direction 1A duty on courts, need to stop treating high-quality output as sufficient evidence that adjustments are unnecessary.
