A recent study published in Twin Research and Human Genetics reveals humor is not inherited, contrasting traits like intelligence. Researchers analyzed twins by asking them to create funny captions, discovering no strong humor similarities between identical twins compared to non-identical twins. This indicates that environmental factors, rather than genetics, significantly influence comedic talent. The findings also explain the scarcity of comedy pairs from the same family, highlighting that humor's complexities are more difficult to assess than other cognitive traits. While a minor genetic influence is possible, it remains largely environmental in development.
"Despite humour's importance, relatively little is known about how we develop our sense of humour or why one sibling can be funny and another cannot."
"The study contained a mix of both identical twins, who share 100 per cent of their DNA, and non-identical twins, who share about 50 per cent of their DNA."
