Knowledge of this social construct (that women are socially expected to be "seen and not heard") is one of the simplest life-hacks for small-group interactions, because once you're mindful of the dynamic it's fairly obvious when someone is getting talked over. It also applies equally well to other introverts, it's just a good social rule in general. Let people finish their thoughts. Most times people aren't doing it to be an asshole, they just are focused on a point or are extroverted and are unintentionally dominating the conversation.
