Researchers at the University of Queensland, Australia, found scientific links between low intelligence and homophobia.
It's the first study conducted outside the USA connecting the low IQ and negative views on the LGBTQ+ community.
The science behind the claims
The study, published in the journal Intelligence, looked at a sample of 11,564 Australians.
Researchers used data from the 2012 Household, Income, and Labor Dynamics in Australia (HILDA) survey. This survey asked questions to assess people's cognitive abilities. They additionally used a 2015 HILDA survey that asked respondents about their attitude towards equal rights.
The participants were asked to rate the statement:
"Homosexual couples should have the same rights as heterosexual couples do."
The researchers used a scale of 1 (strongly disagree) to 7 (strongly agree).
The analysis demonstrated that the less intelligent ones are more likely to be prejudiced against same-sex couples. As the study's authors wrote:
"There are well-known correlations between low cognitive ability and support of prejudicial or non-egalitarian attitudes."
"This paper adds to existing knowledge by providing the first analyses of the associations between cognitive ability and attitudes towards LGBT issues. Individuals with low cognitive ability are less likely to support equal rights for same-sex couples."
The researchers concluded:
"Our results suggest that cognitive abilities play a critical, albeit underappreciated, role in prejudice. Consequently, we recommend a heightened focus on cognitive ability in research on prejudice and better integration of cognitive ability into prejudice models."
Though many assume that homophobia and similar issues are almost a thing of the past, the statistic says different.
The LGBTQ+ community is still facing stigma
If not even science can convince you that your beliefs are beyond reason, then it's no wonder we're still fighting for fundamental human rights.
It does help that another study from the States found that acceptance of LGBTQ people has increased globally since 1980 but has likewise become more polarized.
Yet, the alarming news comes from GLAAD. They claim that for the first time since they started examining attitudes towards LGBTQ people's support has dropped year on year.
In a world where anti-vaxxers and flat-Earthers dominate, nothing surprises us.
There's a comfort in knowing that they can't help their ignorance. But it won't resolve crimes against the LGBTQ+ community committed daily worldwide.
As Einstein famously said:
"Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."
