This paper provides a methodological modification and re-analysis of the data presented by Hier, et al. in 1979 on the presence of unfavorable cerebral asymmetry in autistic patients. In contrast to prior findings, statistical significance was not obtained, suggesting that it is premature to assert that such morphologic anomalies may be considered a risk factor in autism.
