Does being deaf affect intelligence?
Conclusions. Nonverbal intelligence is adversely affected by bilateral hearing loss, even at mild hearing loss levels. Social and economic well being appear compromised in individuals with lower nonverbal intelligence test scores.
Do deaf people have higher IQS?
Results. All studies reported full-scale IQ results; 3 reported verbal IQ results, and 2 reported performance IQ results. Children with unilateral hearing loss scored 6.3 points lower on full-scale IQ, 95\% CI [−9.1, −3.5], p-value <0.001; and 3.8 points lower on performance IQ, 95\% CI [−7.3, −0.2], p-value 0.04.

Is group intelligence testing valid in children with profound hearing loss?
The communication problems of profound hearing loss, the attentive set of deaf children toward psychological examination, and other aspects of test administration rule out group intelligence testing if result are to have validity ( Bridgman, 1939; Hiskey, 1955; Lane & Schneider, 1941; Levine, 1960, p. 221; Vernon & Brown, 1964 ).
