  The fast-growing field of Computational Cognitive Neuroscience is on track to
meet its first crisis. A large number of papers in this nascent field are
developing and testing novel analysis methods using the same stimuli and
neuroimaging datasets. Publication bias and confirmatory exploration will
result in overfitting to the limited available data. The field urgently needs
to collect more good quality open neuroimaging data using a variety of
experimental stimuli, to test the generalisability of current published
results, and allow for more robust results in future work.
