How do implicit biases affect autism referral rates? 

Autism referral rates can be significantly shaped by implicit bias, with unconscious attitudes influencing which children are flagged for further assessment. These biases may lead to certain behaviours being dismissed, misinterpreted, or judged differently depending on a child’s background, ultimately slowing or preventing the referral process. 

Studies have found that even well-intentioned professionals may, without realising it, rely on stereotypes when deciding whether to refer a child for an autism evaluation. This can result in inconsistent autism referral rates across different communities, leaving some children without timely access to the diagnosis and support they need. 

Common Ways Bias Can Affect Referrals 

Below are some of the most frequent patterns through which unconscious bias impacts autism referral rates. 

Overlooking subtle signs 

Behaviours such as mild social withdrawal or unusual communication styles may be attributed to personality rather than recognised as possible signs of autism, especially in quieter or academically capable children. 

Misattributing behaviours 

Repetitive movements or communication challenges can be wrongly linked to home environment or language background rather than investigated as potential autistic traits. 

Inconsistent threshold for referral 

Two children with similar behaviours might receive different referral decisions depending on the assessor’s expectations, experience, or unconscious bias.
