Why do you waste your time and energy arguing with people on social media? You’re not learning anything from that echo chamber!
The key is engagement. If the social media user is broadcasting opinion or ideas from a news source (like many organized trolls – I’m looking at you, 4chan) with no interest in deeper understanding, or simply insulting or deflecting opposition, they’re not really learning much.
Notably, information-seeking motivations was a positive predictor of cross-cutting discussion, but a negative predictor of cross-cutting exposure. This finding indicates that those who utilize SNS for political information are actually less exposed to diverse views. The most plausible psychological mechanism to explain this counter-intuitive finding may be selective exposure; it might be that those who closely follow political news via SNS tend to seek consonant information by friending or following like- minded people or news sources they prefer. This suggests the possibility of SNS functions as homogeneous “echo chambers” where diverse views are hard to find as a result of political fragmentation. However, even for these consonant information-seekers, engaging in cross-cutting political discussion has a strong deliberation effect such that they are significantly more likely to change their original views and get more involved in the issue of discussion than those who are not engaged in cross-cutting discussion.
Cause and effect would be difficult to establish. Does arguing on the internet make you more inquisitive? Or are the arguments symptom of your inquisitive tendencies? Don’t know. The the answer is likely to be, as always, a little bit of both.
