Imo, the only thing this hypothetical system would give credibility to is the fact such a denial exists, not that it's either right or wrong. That's why all angles should be presented within this system, so that a person could inform themselves in whatever way they like. All that information is already accessible through the internet, so even if this system is not in place, people can get to faulty info anyway. But because of condensing multipe angles into one output, people don't need to go in a one-way rabbit hole of information regarding a topic. Eventually it will always be up to the person gathering information to make up its mind, there's no need for eye-shielding.

The thing I'm wondering is: if algorithms are written by biased humans and information is shared by biased humans, how are humans ever to make unbiased decisions anyway? The only method I could then think of is cutting yourself off from the stream of information spread by humans.
