But you knew that.
Data has shown they do less of it and society has been setup this way. Women have been giving up their career - not because they want to but because that's what society and their family pressured them into.
Data has also shown men's view of what counts as domestic work is vastly different from that of women. Sadly a lot of men only do 1/2 the job.
There's plenty of petty sexism around it, I had plenty of people say things like "oh you're giving mom a break," or, "you're babysitting the kids today," and there's very much an expectation that men are worse at it than women. You could view that as misandrist, but (imo) there was often the unspoken assumption that my wife wasn't living up to her responsibilities because I was doing "her" job.
It's not that we don't have those responsibilities, it's that we (as a group) are overwhelmingly less likely to be primary caregivers and to have to adjust our for-money work lives around the those responsibilities.
I am not even sure what this article is claiming to compare but it strikes me as ridiculous to not take the above information into account.
Of course it is harder to provide child care if the kid doesn't even live with you and I would think most the men are providing some form of child support.
