A new social media platform has been released. One of the features is that you can upvote and downvote posts. The algorithm for viewing posts makes it so that once you downvote a post you never see another post similar again. Why might this pose an ethical dilemma?

A. it will provide a balanced experience so the use can be decided
B. it may promote opposing viewpoints, making them more visible
C. it may hide opposing viewpoints, keeping people from seeing them and strengthening confirmation bias
D. it may provide a more moderate experience for the user

C. it may hide opposing viewpoints, keeping people from seeing them and strengthening confirmation bias

This feature could potentially create echo chambers where users are only exposed to opinions and viewpoints that align with their own beliefs, leading to the reinforcement of their existing biases. This can be harmful as it limits exposure to diverse perspectives and inhibits critical thinking and open-mindedness. It could also contribute to the spread of misinformation and the polarization of society.
