Right-wingers tend to be less intelligent than left-wingers

Right-wingers tend to be less intelligent than left-wingers, and people with low childhood intelligence tend to grow up to have racist and anti-gay views, says a controversial new study.

Conservative politics work almost as a 'gateway' into prejudice against others, say the Canadian academics.

The paper analysed large UK studies which compared childhood intelligence with political views in adulthood across more than 15,000 people. 

The authors claim that people with low intelligence gravitate towards right-wing views because they make them feel safe.
