A growing body of research suggests there may be a measurable link between homophobic attitudes and lower cognitive ability, according to a recent study from the University of Queensland in Australia. The large-scale analysis, which examined data from more than 11,500 adults, found that individuals who scored lower on cognitive tests were significantly more likely to oppose equal rights for same-sex couples.
Researchers evaluated verbal, numerical, and problem-solving skills and compared those results with participants’ views on LGBTQ+ rights. After controlling for factors such as education and income, the study found that lower cognitive scores remained a strong predictor of negative attitudes toward same-sex relationships. Verbal reasoning, in particular, showed a notable connection to conservative social beliefs and resistance to LGBTQ+ equality.
While the findings indicate a correlation, experts caution against interpreting the results as a claim that low intelligence causes homophobia. Instead, the study points to cognitive processing style — particularly limited comfort with complexity, unfamiliarity with diverse groups, and stronger reliance on black-and-white thinking — as potential factors linked to prejudicial attitudes.
Supporting research has reached similar conclusions. Studies on emotional intelligence have found that lower scores in empathy and emotional regulation can correspond with stronger bias toward LGBTQ+ individuals. Psychological research has also long associated rigid thinking patterns and authoritarian personality traits with anti-LGBTQ+ beliefs.
Researchers emphasize that cognitive ability is just one element in a complex equation. Cultural environment, religious upbringing, social exposure, and education all play significant roles in shaping attitudes toward LGBTQ+ people. Moreover, experts stress that the findings reflect statistical trends rather than determinations about individuals.
Dr. Francisco Perales, who led the Queensland study, noted that the data highlights the importance of education, exposure, and critical-thinking development in reducing prejudice. “Policies focusing on education and promoting tolerance and understanding are key to fostering inclusive attitudes,” he said in a statement about the findings.
The study arrives at a time of heightened conversation around LGBTQ+ rights and social attitudes worldwide. Advocates say the research reinforces the value of investing in inclusive education and public awareness, while cautioning against using intelligence-based arguments to shame or stigmatize individuals — which experts say can entrench bias rather than reduce it.
Researchers plan to continue examining the cognitive and social roots of prejudice, with the aim of informing policies and programs that encourage openness, empathy, and equality across diverse communities.
