1. A method for providing and aggregating bioelectrical signal data, using a first biosignal detector and a second biosignal detector, the method comprising: providing a stimulus to a first user and to a second user, wherein the stimulus is configured to prompt an action in both the first user and the second user; at the first biosignal detector, automatically collecting a first bioelectrical signal dataset from the first user as the first user performs the action; at the second biosignal detector, automatically collecting a second bioelectrical signal dataset from the second user as the second user performs the action; generating a first anonymized bioelectrical signal dataset from the first bioelectrical signal dataset and a second anonymized bioelectrical signal dataset from the second bioelectrical signal dataset; coupling the first and the second anonymized bioelectrical signal datasets with an action tag characterizing the action; and generating an analysis based upon the first the second anonymized bioelectrical signal datasets.
