In 1972 the University of Scarfolk trialled a new drug that affects the part of the brain that produces racist attitudes.
Researchers observed that the subjects lost control of their bodily functions and had to wear clinical incontinence products. Additionally, many subjects found it difficult to form coherent thoughts, much less verbalise them, and their mental ages registered as those of infants.
The experiment was discontinued, not on ethical grounds, but because the researchers concluded that there were no discernible behavioural and psychological differences between the racists who had taken the drug, and the control group of racists that hadn't.
When the Foreign Secretary read the study's findings, he decided that xenophobia should be extolled as one of Britain's defining virtues and he immediately set out to promote this idea abroad.
