I mean yeah, daughters are treated way differently and essentially serve their brother along with the rest of the family. They are policed more, from their clothes, to behaviour, to freedoms like going out without permission. It's a huge reinforcement of behaviour.

This might just be a correlation thing.

People who have college degrees tend to be more liberal and have fewer children, thus decreasing the chance of their son having a sister.

People in more rural places and people who didn’t pursue higher education trend more conservative and have more kids.

So it’s probably not “having a sister makes men more conservative” it’s more “families with more kids are more conservative”

edit to add: also, people have fewer kids today than they did in the past. so older men are a little more likely to have a sister than younger men — and older men trend conservative

Because they came from an already conservative family that made the sister do housework while they were off the hook? Or I should perhaps say "traditional" considering the data. As someone else pointed out, this is a long term study, including people who were high school seniors in 1965. (Older than me even!)

I think if they had thought to investigate at the time: Do you (male) do household chores like your sister? That question would have illuminated a lot.

Interesting. It's not shocking, though. Every misogynistic has a mother. Most have wives. Having daughters and sisters isn't exactly a rare experience.

Men are still male supremacists.

But the articles observation that boys without sisters get stuck doing women's work does ring true.

From my own observations, a pretty liberal man that I grew up with had one brother. They both did all the cooking/cleaning chores.

A SAHM in a very conservative, religious circle in which women were expected to do all the housework completely shocked me when she told me that her husband did his own laundry. He had only brothers.

A conservative man who staunchly supported womens rights, preferred women doctors and female bosses, who told me that men need women more than the reverse...I believe he had no sisters.

I recently spoke to a guy with 1 sister. He is flabbergasted that women chose the bear over a random man. (All gen x and y [possibly one boomer])

So the morale of the story is that sisters might be an orange flag in the realm of dating.

I wonder also if boys are better off being raised by single fathers than single mothers, so they can see all chores being done exclusively by males...ofc many of those dads will get a new female partner and ruin the data.

I wonder if the data accounts for other factors, such as that conservatives have more children. A boy raised by conservative parents is more likely to have a sister than a boy raised by liberal parents.

I wonder if the results would look different depending on whether the sister is older or younger, how many, etc

Interesting, but one of the studies is about people who were born in 1947. Hard to conclude much about today's society from that.
