Facebook's role in Brexit — and the threat to democracy Sam 30 At 11 p.m. of January 31st, 2020, the United Kingdom finally and formally entered an 11-month transition period of Brexit. However, right until this moment, it had received a total of nearly 11 billion Euros since 2014. Why is there this huge gap between facts and cognitions? It’s due to the abuse of big data and negative advertisements, according to the lecture on TED, “Facebook's role in Brexit — and the threat to democracy”, by Carole Cadwalladr. At first, she shared her experience of being in a town called Ebbw Vale in South Whales. Over 60% of the local citizens voted to leave the European Union while the EU are funding this town for millions of Pounds on colleges, sports centers, road-improvement projects, new train lines, and new railway stations. She asked some local people, and the answers she received from them about the reason they choose to leave are that the EU had done nothing for them, or people were fed up with the immigrants and refugees. However, the statistics showed that this town actually has one of the lowest rates of immigration in the country. After that, a Polish woman, who she had asked question to, told her about the “scary” advertisements of the immigration from Turkey, and it was vanished after it’d been showed up. Besides this, there are still tons and tons of fake news, mostly had been posting on Facebook, and she gave examples like “Turkey's 76m people joining the EU”, “Immigration without assimilation equals invasion”, etc. It’s not only some lies, but messages with hatred and fear that is tearing the whole society and making them apart. The fact is that in the last days before the Brexit vote, "Vote Leave" laundered nearly 75 million pounds through another campaign entity and used them to invest on fake news about the referendum and the EU. Who or what are manipulating these referendums and elections? The answer is a company called “Cambridge Analytica”, which worked for Trump and Brexit. They collected the data and profiles of about 87 million users from Facebook and targeted particular users with personalized ads. Finally, she concluded that these fake news, lies, and all the dark sides of big data can totally destroy our democracy. To research more, I watched a documentary on Netflix called “The Great Hack”. In this documentary, a whistle-blower called Brittany Kaiser that had worked for Cambridge Analytica uncovered the fact that it caused both the UK to leave the EU and Trump to win the election. It has been exposed that it has 5,000 data points on every American voter, and this data can help them to analyze different kinds of voters. For example, in the US presidential election in 2016, they divided the voters into the core democratic supporters, low-level democratic supporters, floating voters, low-level republican supporters, and core republican supporters. The groups that they were working hard on are the low-level democratic supporters, floating voters, and low-level republican supporters. For the low-level democratic supporters, they would spread fake or negative advertisements about Hillary Clinton on their Facebook in order to stop them from voting, and for the floating voters, they would persuade them to vote on Donald Trump. Lastly, for the low-level republican supporters, they would use gun ownership, immigration, and economic issues to build up their determination to vote. Isn’t this strategy similar to the information warfare in Taiwan? A quadrennial presidential election has gone. Is this president, the president that we “choose” to vote or not, the one that we really like or dislike? Or if it is what the technology companies like or dislike? You may think that humans are not that bad at identify what is right or wrong. However, as the proverb goes, “a lie that repeated a hundred times becomes truth.” This is called Goebbels effect. When you receive these information repeatedly, we will unconsciously be used to its appearance, and even accepted it. Many people say that the technology is connecting people around the world. However, at this time, they are pulling us apart.
