I’m not the original person, but I was interested and did some digging myself, so here’s what I found. I’m primarily citing this paper which seemed to cite a lot of other papers to back up its claims, compared to many others, that just utilized a single survey’s results
The paper specifically mentions education all the way down to the preschool level, whereas many other studies didn’t do anything below middle-high school.
Parents, teachers, families, neighbors and the media all have important roles in the sexual education of children and give children sexual education from birth without even noticing that they are doing so. Studies have confirmed that sexual education is a lifelong process that starts at birth.
This is the key point: Sexual education is already effectively taught in many ways in non-educational settings, often with traditional heterosexual norms instilled. (e.g. general discussion of relationships and attraction, consent, mentions of people “trying to have a baby,” things like that) This is education that the respondents themselves did not consider to exist (the majority said they believed sex education of any form did not begin early in adolescence)
However, most of the general resources I can find around how official sex education curriculum are developed, how parents bring up these topics to their kids, and what kids are actually comfortable with discussing themselves, seems to point to an age-appropriate level of education, based on what they’re likely to encounter at their given age range. (e.g. a very young child may be taught to say no if someone asks to see their privates, whereas a young adult may then be taught how to properly use various forms of contraceptives, with the context of different sex positions, because that’s the age within which they’re most likely to engage in those different positions.)
It seems like the age-adjusted measures work best not because they necessarily bring harm if taught to younger individuals (although there’s significantly lacking data on this specific age range and being taught a more comprehensive sex ed curriculum) but rather that it’s more possible to teach it to students as they get older, because they form a larger body of existing knowledge around the topic from peers/media/family, that provides the context required to be more easily taught, and they become more comfortable discussing such topics as they grow older and have a larger existing understanding of them.
You could try teaching an extremely comprehensive sex ed curriculum to students who are much younger, but they would probably just be too uncomfortable to actually care/pay attention/truly learn, is what the evidence I can find seems to point to.
The primary issue is twofold:
If you try viewing even a tiny amount of right leaning content on a fresh social media account on any platform, you’ll see the type of content that gets perpetuated. People simply become indoctrinated by content recommendations that are practically incapable of showing the other side, not to mention that most mainstream media is entirely corporately captured.
The fact that the Democrats were slow to release official policy for Harris’s campaign, indeterminate on Gaza, and had (or really, still have) a very “this is fine, you’re just overreacting, but sure we’ll fix a few things” attitude towards political messaging, only helped Republicans, because it led a lot of people to just vote for the party that promised the most, and that was the Republicans. All the wars would be over, things would be cheaper, all the “bad” people wouldn’t be here anymore, etc.
To a normal person with very little media literacy, those promises sound downright amazing.
I personally think we fix this by at least starting with messaging, since that’s what actually leads most people to make a decision on who to vote for. There were literally people deciding on election night who they wanted to vote for, so messaging is highly important.
The left needs to speak to the immediately visible, material needs of the working people directly. While it’s important to fight against the right on culture war issues to prevent the ceding of ground on things like civil rights and discrimination, I think a lot of left leaning messaging focuses too heavily on that, and as a result, it can seem to right-inclined people that the left has no economic policy. That needs to change.
See: Bernie Sanders, and how he very consistently addresses specific economic issues people face, and has broader support on the right compared to any democratic congressperson. Hell, even JD Vance said Bernie was one of the people he least disliked on the left, and Bernie’s further left than the Democrats. Populist, economic disparity focused, anti-billionaire, pro-worker sentiment is how you change ordinary people’s minds in the current media economy.
As an individual, the most you’ll likely be able to do in this respect is going to be volunteering for phone banking efforts, donating money to left leaning charities focused on reducing economic inequality, and generally bringing these kinds of talking points up in general political discussion with others.
There’s something else that’s commonly overlooked though, and that’s local policy. Think of a city’s “town hall” type meetings that accept public comment. How many people in that city are actually regularly attending a town hall meeting? Think of how few people it really is during a particularly contentious proposal. Now imagine what it’s like when it comes to something like “housing and urban development: reducing the rate of homelessness - meeting no. 57” Almost nobody. Get yourself and a few friends down to your local relevant policy meetings, make even a little noise, and the amount of change you can make as a result can be drastic compared to the actual % of the city’s population you make up.
Pushing for things like ranked-choice voting in local elections can also be very viable, since it’s proven that tends to push voters further left, on average, and it also adds some extra competition that can spur a party like the Democrats into actual meaningful action.
