7 things we've learned about computer algorithms

Algorithms are all around us, using massive stores of data and complex analytics to make decisions with often significant impacts on humans – from choosing the content people see on social media to judging whether a person is a good credit risk or job candidate. Pew Research Center released several reports in 2018 that explored the role and meaning of algorithms in people's lives today. Here are some of the key themes that emerged from that research. Sizable shares of U.S. adults now get news on sites like Facebook or YouTube that use algorithms to curate the content they show to their users. A study by the Center found that 81% of YouTube users say they at least occasionally watch the videos suggested by the platform's recommendation algorithm, and that these recommendations encourage users to watch progressively longer content as they click through the videos suggested by the site.
