[Excerpt from: Finding Reliable Information Online: Adventures of an Information Sleuth]
…For science information in particular, there is concern that crowdsourcing and click rates are influencing what people find when they use a search engine, and this in turn shapes how we make sense of a topic. Broussard calls this a self-reinforcing informational spiral, meaning how people search for a topic then influences how a search engine like Google weighs and retrieves content.
Broussard questions whether we are really making science more accessible to lay people online or if we are moving to a science communication process in which knowledge is greatly influenced by what links search engines pull up: In effect narrowing our options.[i] Moving forward, as many people are fed news, through Facebook, Twitter, or other social media sites, this phenomenon will likely accelerate.[ii] It may be that your friend who keeps “liking” cat videos is also choosing the science news you read.
