Confirmation bias is defined by Dictionary.com  as "the tendency to process and analyze information in such a way that it supports one's preexisting ideas and convictions."
As human beings, we all have confirmation bias when it comes to our belief system; it’s programmed into our brains whether we know it or not. When we digest new information, a biased approach to decision making is often unintentional. We often ignore information that is inconsistent with our beliefs. When an issue is important to us, we have a tendency to find information that supports our own beliefs and ideas, and we limit ideas that do not match our own viewpoint.
As we were researching confirmation bias and how it is assisting in the spread of fake news, we found ourselves thinking a lot about how social media allows our confirmation bias to be more acceptable. We are insulated in our social media bubbles as the algorithms that make up our social feeds allow us to see and hear news that allows us to confirm our biases.
“We can live in the biggest city in the country, and as long as we keep our faces buried in our smartphones, we will feel connected to the group we belong to and read the information we want to believe," stated an article we read in Psychology Today . "And we will be sitting ducks for anyone who wants to feed us fake news.”
