Polynormativity
Also: mainstream-friendly polyamory
The tendency to present one narrow version of polyamory — usually a couple-centred, hierarchical, heterosexual model — as the respectable default, marginalising the messier or more radical configurations.
Polynormativity is an internal critique: the idea that as polyamory has gone mainstream, a particular sanitised version has been elevated as the acceptable face of it. The polynormative model is typically a pre-existing heterosexual couple who 'open up,' keep a clear primary hierarchy, add secondary partners on the couple's terms, and present it all as barely a departure from monogamy. The term was popularised by the blogger known as the Polyamorous Misanthrope and by Andrea Zanin's widely-cited essay on 'the problem with polynormativity.'
The critique is that this framing wins mainstream acceptance precisely by reassuring monogamous audiences — couple stays central, nobody too queer, hierarchy keeps everything legible — while sidelining the configurations that don't fit: solo polyamory, relationship anarchy, queer and non-hierarchical networks, and the people for whom there is no central couple at all. It can also reinforce couple privilege by treating secondary partners as accessories.
Naming polynormativity isn't an attack on hierarchical or couple-centred polyamory, which are legitimate choices. It's a caution against treating one model as the correct or only respectable one, and a reminder that the diversity of honest configurations is the point.
