abstract = {Machine learning (ML) plays an important role in precision
medicine. However, algorithmic biases that favor majority
populations pose a key challenge to ML applications
(Chouldechova 2018; Martin 2019; Obermeyer 2019). In
neuroimaging, there is growing interest in the prediction of
behavioral phenotypes based on resting-state functional
connectivity (RSFC; Finn 2015, 2021; Greene 2018). But
prediction biases/unfairness in this context were not
assessed in the literature. Especially, predictive models
were typically built by capitalizing on large cohorts with
mixed ethnic group, in which the proportions of certain
ethnical groups, e.g. African Americans (AA), are limited.
Whether the models perform equally well across different
ethnic groups was unclear. By using two large-scale
neuroimaging datasets from the United States, we compared
the prediction accuracy between AA and white Americans (WA)
when ML models were trained on different composition of
ethnic groups. We observed larger prediction errors in AA
than WA for most behavioral measures, which was only
limitedly affected by the composition of training
population. We also investigated potential downstream
consequences of biased predictions of behavioral phenotypes
if they were used uncritically.},
