It’s very possible, but I want to caveat that I don’t think it will mean negative content goes away. People very often identify with others based on their common frustration or dislike of other people or problems.
However I don’t think that natural tendency is a problem, it’s the feedback of algorithms designed to amplify it, specifically because of the engagement levels and the attention economy. Every platform desperately needs to trap users for as long as possible to monetize.
So in my mind it’s less about solving negativity, which as others pointed out is useful from time to time, but more about removing a feedback loop for endless negativity spiraling and division, while at the same time providing an incentive for positive content and directly helping each other.
I always remind myself to never discount the power of a feedback loop that pushes us 1% into a worse direction consistently over long periods of time, and thus to never discount the immense power in having a 1% benefit consistently over that same period instead.
The right incentives, even subtly, have the potential to have enormous change. At least in my thinking.
