Income redistributes the chores. It doesn't redistribute who remembers everything.

Researchers call it gendered cognitive stickiness. It's what happens when a woman starts earning more than her partner.

The physical housework drops, that part shifts the way you'd expect. But the planning, the remembering, the noticing what needs to happen before it needs to happen, that stays exactly where it was.

It's a clean result, because it isolates the one variable everyone assumes should fix things: money. If the imbalance were really about time, or leverage, or who's "too busy," then a change in income should move the mental load along with the physical load. It doesn't. The study found the two are decoupled. One responds to earning power. The other doesn't respond to anything measured in this dataset.

That's the distinction that gets lost in most conversations about splitting things "fairly." A chore chart can rebalance who loads the dishwasher. It can't rebalance who's carrying the household in their head, who remembers the excursion form is due Friday, who notices the school shoes don't fit anymore, who's tracking three different people's medical appointments without being asked.

Save this one for the next time someone suggests the fix is to just earn more, or get help, or split things 50/50. The research says the ledger doesn't balance itself just because the numbers change.
