abstract = {Major efforts in human neuroimaging strive to understand
individual differences and find biomarkers for clinical
applications by predicting behavioural phenotypes from brain
imaging data. To identify generalisable and replicable
brain-behaviour prediction models, sufficient measurement
reliability is essential. However, the selection of
prediction targets is predominantly guided by scientific
interest or data availability rather than psychometric
considerations. Here, we demonstrate the impact of low
reliability in behavioural phenotypes on out-of-sample
prediction performance. Using simulated and empirical data
from four large-scale datasets, we find that reliability
levels common across many phenotypes can markedly limit the
ability to link brain and behaviour. Next, using 5000
participants from the UK Biobank, we show that only highly
reliable data can fully benefit from increasing sample sizes
from hundreds to thousands of participants. Our findings
highlight the importance of measurement reliability for
identifying meaningful brain–behaviour associations from
individual differences and underscore the need for greater
emphasis on psychometrics in future research.},
