Learn how language can be used to in a way that it affects the way people perceive reality. Unlike real news, whose purpose is to simply inform, the main purpose of fake news is to confuse and manipulate people.
Algorithms are step-by-step instructions that computers follow to complete tasks, solve problems, and make automated decisions.
Everyone who has accessed the internet has experienced the personalizing actions of algorithms, whether they realize it or not.
Algorithms use data to make predictions about people, including their preferences, attributes, and behaviors.
The Influence of Algorithms
Algorithms can be useful and help to improve our lives. We need them to be able to access a wide range of information on the Internet. For example, to quickly and easily be able to pull up a map on our phones and instantly determine the fastest way to reach our destination.
What happens when algorithms are used to predict who should be hired for a job or who should get a loan, or to decide the type of information we see in our social media newsfeeds, or to calculate credit scores, or even to predict criminal behavior and determine prison sentences?
“Although the impulse is to believe in the objectivity of the machine, we need to remember that algorithms were built by people.”
Algorithmic Bias occurs when algorithms reflect the implicit values of the humans involved in their creation or use. They systematically “replicate or amplify human biases. Search engines can create search results that reflect racist, sexist, or other social biases. For example:
an algorithm used by judges to predict whether defendants should be imprisoned or released on bail, was found to be biased against African-Americans.
Amazon had to discontinue using a recruiting algorithm after discovering gender bias.
Princeton University researchers analyzed algorithms and found that they picked up on existing racial and gender biases:
European names were perceived as more pleasant than those of African-American names
The words “woman” and “girl” were more likely to be associated with the arts instead of science and math.

Megan Pena, age 12, heard the false but pervasive misinformation that the vaccines affect fertility first from a cousin around her age, but then had it reinforced by videos she saw on TikTok, her mom said.
