The echo chamber effect both fascinates and frustrates me.
It’s an observable phenomenon whereby information, ideas and beliefs are amplified (and subsequently reinforced) through a community. It helps define (and refine) the collective conscience, a term coined by the French sociologist Émile Durkheim to refer to the shared beliefs and moral attitudes which operate as a unifying force within any given society.
As a active consumer and producer of content, I’ve often noticed that the same attitudes and opinions are repeated again and again in the blogosphere. Communities of blog readers are created when shared experiences and beliefs align around the content that is being published and shared across various social graphs. Forums are created around common interests/attitudes about an intellectual pursuit, hobby or professional organization. Individual participants and players online tend to create, experience and navigate those online spaces (social networks, discussion forums and other social frameworks) that, in part, reinforce cultural biases and reflect their own worldview. In the extreme, the echo chamber effect can lead to homogenization of content and experiences as a sort of cultural tribalism. When opinions become entrenched and polarizing, we circle the wagons in our little camps and tell the same old stories that we always have. Scary thought, eh?
Over time, the echo chamber can sanitize discourse by simply drowning out opinions and viewpoints that are perceived to be contrary or disruptive to the community. Internet activist and writer Eli Pariser argues in his book The Filter Bubble that personalized searching algorithms in Google and Facebook leads to users getting less exposure to conflicting viewpoints, isolating them intellectually in their own informational bubble. In short, we are creating individualized universes of information. Think about your personal social graph on Facebook or Twitter for a moment:
- Does the content shared bleed together after a while?
- Do sources that you read tend to center around key repetitive themes?
