Would Providing Skills Make Social Media Less Polarising?

I have already posted on Carlo Rovelli's advocating, that all primary school children, should be taught the basics (yet another thing for the 'under-employed' teachers to do!) of probability theory and statistics to help them make sense of the digital world, to which they will inevitably be exposed. I professed doubts at the time of posting, and think that new data about the online spread of QAnon ideas in the UK (https://www.theguardian.com/commentisfree/2020/oct/27/how-qanons-conspiracies-gained-traction-uk-social-media), suggests that wider statistical competence will do little to save us. Clearly, the main problem with social media platforms is that they are designed (largely for advertising purposes) to divide us into 'camps'. Users of the platforms are regularly exposed only to the ideas of others who are like-minded. One rarely gets exposed to material that is fundamentally at odds with our own values and preferences (and if we are, we can always block or 'unfriend' them). This is a situation in which confirmation bias (where one tends to uncritically accept information that supports our own ideas and to reject or minimise the importance of findings that run counter), runs riot. I am really not sure what we can do about this. Teaching primary school kids about confirmation bias would a) be very difficult and b) likely to lead to accusations of 'brain washing'. I am also sure that the owners of social media platforms a) are happy with the status quo as it maximises their finances, b) would resist attempts to widen the range of viewpoints presented to individuals as this would act as a disincentive to participation and c) would not like to be told how to reduce confirmation bias. Although increasing numbers of people get their 'news' from social media (rather than newspapers or radio/TV), they seem to regard participation as entertainment rather than educational. Their views are also honed via these self-selected platforms, so it is hardly remarkable, that many groups (with good or bad intentions), increasingly seek to identify folk who are amenable to their arguments and focus on sections of these 'communities' to push their ideas. It's all a bit cult-like! I suspect, however, that the vast majority of platform users, don't care.
