Misleading face-based judgment of cognitive level in intellectual disability: the case of trisomy 21 (Down syndrome).

Jänsch et al. (2014) asked the adults to look at photos of the children with Down syndrome.

Each adult rated how "trisomic" the child’s face looked and guessed the child’s IQ.

The team then compared these guesses to the child’s real test scores.

Faces that looked "more Down syndrome" got lower IQ guesses.

The guesses had zero link to real test scores.

Only the real tests told the truth about each child’s ability.

López-Riobóo et al. (2019) later showed that young adults with Down syndrome have stronger auditory than visual language gaps.

Their work adds detail: test both channels, not just one.

Sutton et al. (2022) pooled 26 studies and found small, uneven executive-function gaps across all intellectual disabilities.

Together the three papers say: use wide, formal tests; surface clues mislead.

Waddington et al. (2020) found that school plans often skip vision needs in Down syndrome.

Claire’s warning about face bias pairs with Hannah’s: check the plan and the eyes, not the face.

Your eyes can trick you. A child who "looks" lower functioning may test in the average range for Down syndrome. Always run full cognitive, language, and vision assessments before writing goals. Swap the photo for the protocol.
