You actually can with Facebook and Twitter. As a moderate, I like seeing many different views on a subject. My approach to get the pulse of social media on political issues is to have a lot of
really different kinds of people on my friends list. I also gave likes to and commented on any interesting things they said in case Facebook algorithms prioritize them away.
If this post got widely shared, Id see responses in Facebook from people including several types of feminists, business woman arguing cold numbers/profit, males/females arguing black angles or activism (had one just like researcher in OP), male/female opponents of both (white and non-white), activists citing whoever gets ignored most (eg nativelivesmatter to BLM activists), at least one reactionary racist whose dismissals will be common, and thoughtful oddballs who I cant easily predict. Each will have reflexive comments or even articles with evidence for their view or against others.
It can be overwhelming to look at it all but I do on critical issues to ensure Im basing my views or actions on big picture rather than a filter bubble. If not a big issue, Ill just lazily click on my feed which is definitely a bubble of folks with similar interests, the most discussions/tags/messages, or most likes. I noticed Facebook ruined my scheme more over time where I have to actually click on specific names to see those kind of view points. Ive also been told Twitter would be ideal for this and know folks that do it there but still havent got on it myself for common anti-Twitter reasons. ;)
So, you can currently do that with both platforms. If you pick representative people (gotta do that right), you will see about everything they believe as a group about what's trending in their groups or nationally. You will have more good info and see more info as bad since tunnel vision the alternative approach creates is part of why bad info spreads. Lastly, it's just really interesting if you're a people watcher like me to see all the different ideas, jokes, trends, lifestyles, etc people share. I didnt originally add these people to study politics of rough topics: each was interesting and/or helpful in discussions, often face-to-face, before I added them. So, it's fun, enlightening, and sometimes challenging to have truly, diverse friends around you.
Note: Might be worthwhile to try to design some kind of meta-search engine designed to mimick what I just described. My quick guesses at how to build it suggest it would be really tricky to deal with human factors. Ill just leave it at saying the concept would be useful.
