Worldwide Campaign to stop the Abuse and Torture of Mind Control/DEWs
This article in New Scientist describes an experiment in causing empathy. Four people wired to an EEG recorder watched films which provoked amusement, anger, or sadness. Their EEG responses were connected to 4 other people who received the EEG responses via electrodes in armbands, and showed the corresponding emotions by hand or arm movements or signs.
The experimenter is thinking of linking this type of thing to people`s social media profile, so friends could experience the same emotions at the same time.
