Xenophobic British citizens who believe that immigrants threaten their values and way of life were more likely to have voted in favour of the UK to leave the European Union, a study has found.
The research shows that xenophobia was a strong predictor of a Brexit vote regardless of people's age, gender or education.
In June 2016, almost 52 per cent of British citizens who participated in a referendum on the withdrawal of the UK from the EU, commonly known as Brexit, voted to leave.
Following this largely unexpected result, some explanations pointed to the role of a voter's age, gender or education in their voting behaviour while others wondered whether the "Leave campaign" might have mobilised xenophobic attitudes by emphasising a fear of foreigners.
To investigate these questions further, researchers led by Agnieszka Golec de Zavala, at the Goldsmiths, University of London, measured the effect of xenophobia - or the belief that immigrants to the UK threaten the country - on voting behaviour.
They found that this belief was strongly related to the tendency to vote in favour of Brexit and to be happy with the referendum's outcome, regardless of age, gender or education.
The researchers then tried to establish what kind of people believe that immigrants threaten the UK.
They found three distinct groups: authoritarians, who fear other groups will threaten the traditional status quo in their country; people high in social dominance orientation, who compete for their group's dominance over immigrants; and collective narcissists, who believe the UK is so great it is entitled to privileged treatment but complain this 'true importance and value' is not recognised by other countries.
The research also found that people who just thought it was great to be British or just valued their British identity were not more likely to reject immigrants or vote for Brexit.
Although other studies have implicated right wing authoritarianism and social dominance orientation in voting for radical right-wing parties because of the perceived threat of immigrants, collective narcissism has almost never been examined in the context of political behaviours such as voting.
The research introduces collective narcissism as a new variable to consider when making predictions for political behaviour.
"From Brexit, Trump and support for Vladimir Putin in Russia to the nationalist, ultra- conservative government in Poland, studies from our and other labs show that collective narcissism systematically predicts prejudice, aggression and a tendency to interpret innocent behaviours as provocation to the national group," said Golec de Zavala.
The researchers caution that as the study was conducted after the Brexit referendum, it may be that the 'yes' vote increased people's xenophobia.
It is clear from the research that the vote was associated with prejudice, but this relationship might have been strengthened by the outcome of the referendum because people felt more empowered to express xenophobic attitudes.
