With the approach of the US election in 2020，Some scholars said，Algorithm changes in information dissemination methods and guidance for the public's willingness seems to have not yet attracted people to pay attention to，We must be alert to social media "algorithm" intervention elections。

Study shows，People who can better use social media for publicity，It is very likely to gain an advantageous position in the election。John Quelch, a professor at Harvard University Business School, Bet365 lotto review said，Young people are more likely to be affected by social media，They use social media in large quantities to affect political ecology。Jennifer Grygiel, an associate professor at Xuecheng University Communication, said，Multiple research evidence indicates，"Facebook" modified news subscription algorithm objectively suppressed the opportunity to obtain credible information，Instead, let a lot of false news take advantage of it，This leads to candidates who can make full use of social media algorithms and communication mechanisms to win public attention。

Glagier thinks，Politicians are now paying more and more attention to social media。They know the importance of using social media。bet365 Play online games On "Facebook" and other platforms，Any attractive event may cause users to spread and hotly debate。People should pay attention to the impact of social media on the United States。2015，"Facebook" updated the algorithm。After update，The main source of information obtaining information is no longer news media，but information from friends and family members。Although the original intention of this algorithm is to keep users not to miss the dynamics of relatives and friends，But there are survey results show，This algorithm greatly reduces the number of interaction between "Facebook" users and reliable news agencies。June 2016，"Facebook" updated the algorithm again。This update makes bet365 best casino games "Facebook" users more information from relatives and friends they pay attention to。January 2018，"Facebook" adjusted the algorithm again，once again reduced the information flow of users from traditional press and publishing institutions，The possibility of people's contact with serious news will become lower and lower。Glageir worried，False information will be further spread on social media。

Some scholars think，Although there is no evidence to indicate that the algorithm changes in "Facebook" have political intentions，But "Facebook" still evaluates and revised its algorithm operation。The algorithm for social media is used by political intentions，Glagier Call for，The United bet365 Play online games States should introduce new regulations and regulations，It is forbidden to social media for temporary、Stage algorithm modification and adjustment，Especially during the operation of major political and economic activities，To prevent related vulnerabilities from being used inappropriately。At the same time，It should keep the algorithm transparent，Enhance the public's understanding of the algorithm。Social media should not control the public opinion or voting behavior through a closed algorithm system。
