The "meet market" changes, but some things don't.well i can see somethings always being the same
* The underlying matching system is competitive. Unsurprising, given that life is shaped by evolution
* The "hotness scale" varies a bit, but it's not a cultural/societal construct. Most of the differences are due to the reference templates in our visual system being "programmed" to the local phenotypes early in life.
* The resource availability and "status" aspects of the matching system are stable over time
* ... there's more, but the important ones would take this well off-topic
It's much more interesting to look at the unstable parts, which are societal/cultural constructs:
* Acceptable XX behaviors prior to and between LTRs
* XY responsibilities for certain outcomes. This is almost entirely absent from the game at the moment, but I remember when they were very important
* The "testing game" (who approaches, who pays, "courting" behaviors, etc). This is currently badly broken, but the game doesn't work without some structure in this, so the chaos will pass (unless the population collapse hits first).
* Family involvement and expectations. For now, distorted but not completely broken.
* The locally acceptable lies about the mating game. These shape the inter-personal dialog between potential relationship partners. It's very important for ASDs, but for some reason that escapes me it doesn't get discussed here.
Hookup culture has changed this a lot, and offers the simplest imaginable negotiation: testing "DTF?" /lol. But I'm going with "distorted but not broken" status again.
