Title: Randomized trials in EEG classification experiments are mandatory as   drift is pervasive
Primary area: applications to neuroscience & cognitive science
Keywords: EEG

Abstract: Temporal correlation is demonstrated in three public EEG datasets.
Filtering does not remove the correlation.  The community is cautioned
that a substantial number of recent publications are flawed due to a
confound between temporal correlation and stimulus class, despite
claims that filtering removes the correlation.  The only known way to
avoid this confound is through randomization.

TL;DR: We demonstrate that about 100 papers are flawed because they don't use randomized trials
