But the aggregate trend is quite clear.
How would aggregation of unreliable data help?
And the post that started this sub thread was about how their experience didn’t show the trend. But no one in the social sciences expects every sample to follow the trend. There will be numerous exceptions. Just like sometimes when one rolls a pair of dice one gets a twelve.
That twelve is an absolutely an accurate sample from the data but just because one sometimes gets an outlier it doesn’t mean that there is no central tendency.
While that can be true, I wonder how much of it is true. It's pretty common in therapy to hear partners saying the other one doesn't contribute, but further investigation can often turn up observation biases.
I am a dad, FWIW.
I've heard this from many moms, "My husband does so little in terms of housework, childcare, play and mental load, that it is actually easier when he is out of the house; when he is home, I essentially have to take care of an additional child." I even know some moms that organize playdates for their husband, as in ONLY the husbands, so that that the husbands are out of the house.
On the other hand, I know of two separate marriages that fell apart because the husband worked, did all the child care and housework, while the mom stayed home and doomscrolled. After a few years of no improvement, divorce. Of course many things could be at play here... screen addiction, post-partum depression, etc.
Raising kids is complex, time-consuming, hard, and amazing. It takes a lot of energy, people, and love. I always try to assume people are doing their best, though sometimes even that's tough.
You can also find that much of the research about household duties is biased against the type of work that men have traditionally done (eg excluding yard work, maintenance, etc).
My ex wife does this. I take my issues with her to a therapist (instead of online forums). FWIW I have always been more present than her in our child’s life and certainly pay a lot more too. One data point, but it’s in the population you’re referring to.
Some people want sympathy at the expense of their partner’s reputation.
