Demands:

Robin Hanson:

"While it is tempting to interpret demanding partners in terms of their negotiating position, I think demandingness is more likely due to efforts to screen partners for devotion. Women do more of this than men, even when their negotiating position is weaker."

"Answer if you know couples where one is, in effect, more demanding. This might be shown via more anger, suspicion, anxiety, stress, complaints, or threats to leave. In these relation, on average which has the worse bargaining position (eg, they'd be hurt more if relation ended)?"
