The study, which was conducted by Satoshi Kanazawa, a researcher at the London School of Economics, found that a woman's urge to have children decreases by a quarter for every 15 extra IQ points.
When Kanazawa, who used data from the UK's National Child Development Study, added controls for economics and education, the results remained the same - the more intelligent the woman, the less likely she was to have children.
Worsley isn't the UK's only famously clever childless woman, with others including BBC presenter Kate Humble and actress Helen Mirren.
In the USA, Oprah Winfrey, Cameron Diaz and Eva Mendes are among the famous names who have said they'll never become mothers, with Diaz adding: 'I have the life I have because I don't have children.'
Mendes too has said that she values her lifestyle too much to share it with children. 'I don't want kids,' she said. 'I love sleep and I worry about everything.'
Humble, meanwhile, told the Times that she just 'doesn't have a maternal gene' and resolved not to have children at the age of 14.
'People are very judgmental,' she added. 'It's as if I made a selfish decision not to have children, but I never, ever, wanted them.'
Humble and Mendes certainly aren't alone, with figures released by the Office of National Statistics revealing that the proportion of women without children has almost doubled since the 1990s.
One in five 45-year-olds is childless, while among those with degrees, the figure rises to 43 percent, suggesting that Kanazawa's findings are sound.
