Some may worry about the prospect
that political operators will generously spray the crowd with oxytocin at rallies of their candidates 
. The scenario may be rather too close to reality for comfort, but those with such fears should note that current marketing techniques — for political and other products — may well exert their effects through the natural release of molecules such as oxytocin in response to well-crafted stimuli. Civic alarm at the prospect of such abuses should have started long before this study, and the authors cannot be blamed for raising it.
