“An echo chamber is a metaphorical description of a situation in which information, ideas, or beliefs are amplified or reinforced by communication and repetition inside a defined system. Inside a figurative echo chamber, official sources often go unquestioned and different or competing views are censored, disallowed, or otherwise underrepresented.”
I think the intent of the advent of the internet was to bring people together and share information quickly with less effort, however social medias have allowed us to selectively pick and choose what we care to hear/see (with likes) and block out otherwise contrasting perspectives that may otherwise have changed our perceptions.
Are we looking at our feeds in hopes to explore new information, or are we continuing the same rhetoric that we already knew?
Awareness is important; acceptance to unappealing opinions at the very least builds tolerance and at the very most inspires cooperation, community, and consensus.
