If sniffing oxytocin makes you more trusting raises ethical issues about neuromarketing of everything from soda to political candidates. Clearly, the antidote to oxytocin is a big sniff of cocaine: it destroys the trust one might have with a wave of paranoia. ;)

I am convinced that Mark Felt went to the press with his information not only because of his "contempt for the Nixon White House" but also for fear for his own safety.
