Long before he had a tribe of children to call his own, actor Brad Pitt broke down in tears on primetime TV when talking about how much he wanted to have a daughter.
“Little girls, they just crush me — they break my heart,” he said.
Now with three daughters — and three sons — to call his own, Pitt has more than achieved his dream. He will also have had ample opportunity to experience the powerful influence that little girls have on their fathers: The most masculine man will learn to love pink, take part in endless games of dressing up and even bake fairy cakes if that’s what his little princess desires.
New research shows, however, that daughters have an even more profound effect on their daddies: Fathers, say Andrew Oswald from the University of Warwick and Nattavudh Powdthavee, of the University of York, will shift their political allegiance for their daughters. Using research from the British Household Panel Survey, Oswald and Powdthavee found that the more daughters there are in a household, the more likely their father is to vote Labour or Liberal Democrat.
In an unpublished paper that has been submitted to an economics journal, the pair say: “This paper provides evidence that daughters make people more left-wing, while having sons, by contrast, makes them more right-wing.”
The academics go on to speculate that left-wing families become so through a predominance of females down successive generations, as anecdotally evidenced by British actor Tony Booth [father of former British prime minister Tony Blair’s wife, Cherie Blair] and his many daughters, or the late leader of the Labour Party, John Smith, and his three daughters.
The study showed that in the UK, compared with males, females tend to be more in favor of higher taxes to fund provision such as the country’s health service. Higher taxation also affects them less since they tend to be in a lower income bracket.
“As men acquire female children,” Oswald said, “those men gradually shift their political stance and become more sympathetic to the ‘female’ desire for a ... larger amount for the public good. They become more left-wing.”
“Similarly, a mother with sons becomes sympathetic to the ‘male’ case for lower taxes and a smaller supply of public goods. Political feelings are much less independently chosen than people realize,” he said. “Children mold their parents. It’s so scientifically attractive because it’s out of the parents’ control — whether they have a boy or a girl.”
The researchers have been accused of propagating gender stereotypes and of perpetuating the idea that women go in for softer politics than men. But their work mirrors recent findings by US researchers who looked at the voting records of US congressmen before and after having children. In a joint paper, US sociologist Rebecca Warner from Oregon State University and the economist Ebonya Washington from Yale University found that support for policies designed to address gender equity was greater among parents with daughters. The result, they said, was particularly strong for fathers.
Because parents invest a significant amount of themselves in their children, the authors argue, the anticipated and actual struggles that offspring face and the public policies that tackle those begin to matter more to those parents.
They say that people who parent only daughters are more likely to hold feminist views, with congressmen who have female children tending to vote liberally on issues from reproductive rights and teenage access to contraceptives to flexibility for working families and education.
“I argue that these results generalize to voting for entire political parties. We document evidence that having daughters leads people to be more sympathetic to left-wing parties. Giving birth to sons, by contrast, seems to make people more likely to vote for a right-wing party,” Oswald said.
Oswald found that, among parents with two children who voted for the left (Labour or Liberal Democrat), the mean number of daughters was higher than the mean number of sons. The same applied to parents with three or four children. Of those parents with three sons and no daughters, 67 percent voted for the left. In households with three daughters and no sons, the figure was 77 percent.
There are those who dispute the interpretation of the findings, but evidence nonetheless abounds of daughters who have tamed the most manly of men. When rapper Sean (P Diddy) Combs and his girlfriend Kim Porter had identical twin daughters two years ago, the New York musician admitted that “having girls changes you for the better.”
Actor Sylvester Stallone, star of the Rambo and Rocky films, altered his career path after the birth of his daughter, Sophia, in 1996.
“Switching course at this point in my life isn’t easy [but] the birth of my daughter was a subtle indication of which way I should go. I want to get back to more emotional, character-driven films,” he said.
While not claiming to have shared the testosterone-defined personalities of Combs or Stallone, Colin Brazier, a news presenter for British TV station Sky News, also admits his five daughters have softened him.
“I am definitely a softer man because of my daughters,” he said. “I think being the father of girls has made me more empathetic and more skilled in certain forms of negotiation that are particular to bringing up girls. There is something about watching my daughters interact with each other. Girls are so cooperative with each other whereas boys have more kinetic energy. Because of this, I think it’s possible to enjoy daughters in ways you don’t enjoy boys, who need so much more intervention. Because of this, having daughters has made me more reflective.”
Margaret McAllister, a psychologist who has spent the last 25 years specializing in child development and family functioning, said the studies revealed the importance of home environment over work and social influences, in forming an individual’s personal and political views.
“Children have experiences and are exposed to knowledge, opinions and attitudes that are completely new to their parents,” she said. “Because of this, children reveal a whole new world to their parents, educating them into seeing the world through their eyes. It makes perfect sense that if a parent has children of one gender, they are more likely to be aware, alert and sensitive to issues that affect that gender.”
But Arthur Mayne, a biologist who has three sons aged from 12 to 18 years, disagrees.
“This is a simplistic scientific [theory] that could be accused of gender stereotyping, especially the idea that women are more likely to be softer politically than men,” he said.
“While it is true that men biologically determine the sex of their children, recent studies seem to prove that women with higher levels of testosterone — who are more likely to display dominant, positive behaviors — seem to produce more sons than daughters. Women with lower levels of testosterone, who are more likely to be empathetic and better listeners, tend to produce more daughters. It could be that the women who are most likely to produce daughters pick a partner who is closer to her more empathetic attitude to life,” he said. “Hence people who are already more liberal may produce more daughters and those who are already conservative may produce more sons.”
From the Iran war and nuclear weapons to tariffs and artificial intelligence, the agenda for this week’s Beijing summit between US President Donald Trump and Chinese President Xi Jinping (習近平) is packed. Xi would almost certainly bring up Taiwan, if only to demonstrate his inflexibility on the matter. However, no one needs to meet with Xi face-to-face to understand his stance. A visit to the National Museum of China in Beijing — in particular, the “Road to Rejuvenation” exhibition, which chronicles the rise and rule of the Chinese Communist Party — might be even more revealing. Xi took the members
A Pale View of Hills, a movie released last year, follows the story of a Japanese woman from Nagasaki who moved to Britain in the 1950s with her British husband and daughter from a previous marriage. The daughter was born at a time when memories of the US atomic bombing of Nagasaki during World War II and anxiety over the effects of nuclear radiation still haunted the community. It is a reflection on the legacy of the local and national trauma of the bombing that ended the period of Japanese militarism. A central theme of the movie is the need, at
The Chinese Nationalist Party (KMT) and the Taiwan People’s Party (TPP) on Friday used their legislative majority to push their version of a special defense budget bill to fund the purchase of US military equipment, with the combined spending capped at NT$780 billion (US$24.78 billion). The bill, which fell short of the Executive Yuan’s NT$1.25 trillion request, was passed by a 59-0 margin with 48 abstentions in the 113-seat legislature. KMT Chairwoman Cheng Li-wun (鄭麗文), who reportedly met with TPP Chairman Huang Kuo-chang (黃國昌) for a private meeting before holding a joint post-vote news conference, was said to have mobilized her
Before the Chinese Communist Party (CCP) and its People’s Liberation Army (PLA) can blockade, invade, and destroy the democracy on Taiwan, the CCP seeks to make the world an accomplice to Taiwan’s subjugation by harassing any government that confers any degree of marginal recognition, or defies the CCP’s “One China Principle” diktat that there is no free nation of Taiwan. For United States President Donald Trump’s upcoming May 14, 2026 visit to China, the CCP’s top wish has nothing to do with Trump’s ongoing dismantling of the CCP’s Axis of Evil. The CCP’s first demand is for Trump to cease US
