A group of researchers from Germany and the United States have published a study which concludes that doping ‘xenophobic’ populations with massive quantities of the estrogen-linked hormone Oxytocin will cure nationalism – making native citizens more accepting and generous towards migrants.
As co-author René Hurlemann said in a related study; “Given the right circumstances, oxytocin may help promote the acceptance and integration of migrants into Western cultures.”
I saw this in a movie once. The Government gave the entire population of a planet a drug to make them peaceful and compliant. Most of them died of apathy. The rest became Reavers.
