海外TECH	Engadget	Hitting the Books: Modern social media has made misinformation so, so much worse	https://www.engadget.com/hitting-the-books-tyrants-on-twitter-david-sloss-stanford-university-press-150043542.html?src=rss	Hitting the Books Modern social media has made misinformation so so much worseIt s not just that one uncle who s not allowed at Thanksgiving anymore who s been spreading misinformation online The practice began long before the rise of social media ーgovernments around the world have been doing it for centuries But it wasn t until the modern era one fueled by algorithmic recommendation engines built to infinitely increase engagement that nation states have managed to weaponize disinformation to such a high degree In his new book Tyrants on Twitter Protecting Democracies from Information Warfare David Sloss Professor of Law at Santa Clara University explores how social media sites like Facebook Instagram and TikTok have become platforms for political operations that have very real and very dire consequences for democracy while arguing for governments to unite in creating a global framework to regulate and protect these networks from information warfare David SlossExcerpted from Tyrants on Twitter Protecting Democracies from Information Warfare by David L Sloss published by Stanford University Press by the Board of Trustees of the Leland Stanford Junior University All Rights Reserved Social Media Misinformation and Democratic GovernanceGovernments were practicing disinformation long before the advent of social media However social media accelerates the spread of false information by enabling people to reach a large audience at low cost Social media accelerates the spread of both misinformation and disinformation “Misinformation includes any false or misleading information “Disinformation is false or misleading information that is purposefully crafted or strategically placed to achieve a political goal nbsp The political objectives of a disinformation campaign could be either foreign or domestic Prior chapters focused on foreign affairs Here let us consider domestic disinformation campaigns The Pizzagate story is a good example In fall a Twitter post alleged that Hillary Clinton was the kingpin of an international child enslavement and sex ring The story quickly spread on social media leading to the creation of a discussion board on Reddit with the title Pizzagate As various contributors embellished the story they identified a specific pizza parlor in Washington DC Comet Ping Pong as the base of operations for the child sex operation These bizarre and evidence free allegations soon spread beyond the dark underbelly of the internet to relatively mainstream right wing media such as the Drudge Report and Infowars Alex Jones the creator of Infowars has more than million follows on YouTube and followers on Twitter by spreading the rumors Jones vastly increased their reach Jones has since been banned from most major social media platforms Ultimately a young man who believed the story arrived at Comet Ping Pong with an AR semiautomatic rifle and opened fire unloading multiple rounds Although the story was debunked pollsters found that more than a quarter of adults surveyed were either certain that Clinton was connected to the child sex ring or that some part of the story must have been true Several features of the current information environment accelerate the spread of misinformation Before the rise of the internet major media companies like CBS and the New York Times had the capacity to distribute stories to millions of people However they were generally bound by professional standards of journalistic ethics so that they would not deliberately spread false stories They were far from perfect but they did help prevent widespread dissemination of false information The internet effectively removed the filtering function of large media organizations enabling anyone with a social media account ーand a basic working knowledge of how messages go viral on social media ーto spread misinformation to a very large audience very quickly nbsp The digital age has given rise to automated accounts known as bots A bot is a software tool that performs specific actions on computers connected in a network without the intervention of human users Political operatives with a moderate degree of technical sophistication can utilize bots to accelerate the spread of messages on social media Moreover social media platforms facilitate the use of microtargeting the process of preparing and delivering customized messages to voters or consumers In summer political activists in the United Kingdom built a bot to disseminate messages on Tinder a dating app that were designed to attract new supporters for the Labour Party The bot accounts sent between thirty thousand and forty thousand messages in all targeting eighteen to twenty five year olds in constituencies where the Labour candidates needed help In the ensuing election the Labour Party either won or successfully defended some of these targeted districts by just a few votes In celebrating their victory over Twitter campaign managers thanked their team of bots There is no evidence in this case that the bots were spreading false information but unethical political operatives can also use bots and microtargeting to spread false messages quickly via social media nbsp In the past two decades we have seen the growth of an entire industry of paid political consultants who have developed expertise in utilizing social media to influence political outcomes The Polish firm discussed earlier in this chapter is one example Philip Howard a leading expert on misinformation claims It is safe to say that every country in the world has some homegrown political consulting firm that specializes in marketing political misinformation Political consultants work with data mining companies that have accumulated huge amounts of information about individuals by collecting data from a variety of sources including social media platforms and aggregating that information in proprietary databases The data mining industry supplies the information that campaign managers need to make strategic decisions about whom to target where when with what message and over which device and platform Political consulting firms use both bots and human operated fake accounts to disseminate messages via social media A fake account is a social media account operated by someone who adopts a false identity for the purpose of misleading other social media users about the identity of the person operating the account They take advantage of data from the data mining industry and the technical features of social media platforms to engage in very sophisticated microtargeting sending customized messages to select groups of voters to shape public opinion and or influence political outcomes Social media algorithms allow for the constant testing and refinement of campaign messages so that the most advanced techniques of behavioral science can sharpen the message in time for those strategically crucial final days before an important vote Many such messages are undoubtedly truthful but there are several well documented cases where paid political consultants have deliberately spread false information in service of some political objective For example Howard has documented the strategic use of disinformation by the Vote Leave campaign in the final weeks before the UK referendum on Brexit nbsp It bears emphasis that disinformation does not have to be believed to erode the foundations of our democratic institutions Disinformation does not necessarily succeed by changing minds but by sowing confusion undermining trust in information and institutions and eroding shared reference points For democracy to function effectively we need shared reference points An authoritarian government can require citizens to wear masks and practice social distancing during a pandemic by instilling fear that leads to obedience In a democratic society by contrast governments must persuade a large majority of citizens that scientific evidence demonstrates that wearing masks and practicing social distancing saves lives Unfortunately misinformation spread on social media undermines trust in both government and scientific authority Without that trust it becomes increasingly difficult for government leaders to build the consensus needed to formulate and implement effective policies to address pressing social problems such as slowing the spread of a pandemic	2022-07-10 15:00:43
