7 things weve learned about computer algorithms
The inner workings of even the most common algorithms can be confusing to users. Facebook is among the most popular social media platforms, but roughly half of Facebook users – including six-in-ten users ages 50 and older – say they 
People's comfort level with algorithms often depends on how they are used. For instance, three-quarters of social media users say it is acceptable for social media platforms to use data about them and their online habits to recommend events they might like to attend. But a substantial majority of users think it is not acceptable for social media platforms to use their data to deliver messages from political campaigns.
Proponents of algorithms often argue that these systems can lead to fairer and more effective decision-making, but others worry that these processes will simply reinforce existing biases and disparities. When asked for their own views on this subject, nearly six-in-ten Americans (58%) think computer programs will always reflect the biases of their designers, while 40% believe it is possible for computer programs to make decisions that are free from human bias.
Algorithm-driven social media platforms can produce feelings of anger in their users – and most Americans are skeptical that the content they see on social media reflects reality. Nearly all the content an individual user might see on social media is chosen by computer programs attempting to deliver content that they might find relevant or engaging. When asked about emotions they experience from the content they see on social media, the largest share of users (44%) say they frequently feel amused – but 25% say they frequently feel angry as a result of what they see on social media. More broadly, a majority of Americans (74%) think the content people post on social media does not provide an accurate picture of how society feels about important issues.
As algorithms become more advanced, technology experts predict that these systems will amplify human effectiveness – but also threaten human autonomy, agency and capabilities. In a recent canvassing of 979 technology experts, these experts predicted that advances in algorithm-driven artificial intelligence will potentially revolutionize areas such as health care, education and broad aspects of the economy. Yet, most experts, regardless of whether they are optimistic or not, expressed concerns about the long-term impact of these new tools on the essential elements of being human.
