Did Cambridge Analytica’s Facebook Harvesting Decide the US Elections?

Have the Russians and Cambridge Analytica been abusing Facebook to influence the US and British elections by spreading fake news to receptive users? Absolutely Yes! Has this abuse had an impact on the US elections and Brexit? Most likely not! It becomes increasingly clear that people like Donald Trump (through his former confidant Steve Bannon) and Vladimir Putin have been (illegally) harvesting user profiles on Facebook and setting up Twitter bots to spread fakenews on Facebook and Twitter . Facebook by its own account admitted that fake news produced by the Russians and US Alt-right proponents might have been seen by millions of users. What has not been shown, however, is what effect this has had on the actual voting behavior. I argue that this effect has been minimal, most likely smaller than the voting margin for Trump in the US elections, and for Brexit in the UK. While a group of researchers has done an t horough analysis of the dynamics of the spread of ...

Human-computer symbiosis, or computers taking over?

In the earlier days of computer science (1990ties), when I was a post-doc at MIT, there was huge discussion among AI researchers, with people like Marvin Minsky on one side, who said that computers eventually would become smarter than humans, and the majority agreeing that this would never be possible. Fast-forward 25 years, and there is no question that Marvin Minsky was right. Researchers today envision one of three possible scenarios: the first, least fearsome one, that the human is telling the machine what to do, secondly, we have true human-machine symbiosis with computer and human being equal partners on a task, or third, the machine telling the human what to do. Looking at the current stock market fluctuations, it unfortunately seems we already firmly reached the third scenario, with computers taking over. When after multiyear growth and a record high of the Dow on January 26 2018, a few days later on February 4, the Dow lost 1175 points in a single day, this was its bigges...

What Is the Influence of Your Tweets?

What is the real-world impact of Twitter? It seems that one well-placed tweet can #makeAmericaGreatAgain – at least it got Donald Trump elected as US President, or did it?  One year after his election, even the Russian press says Trump did not “Make America Great Again” . In this post I would like to explore if Twitter really can help an aspiring leader to change the world, promote a cause, or further his or her own career. I will start by looking at the Twitter behavior of the World’s most famous people, and then identify some characteristics of the most active or prominent twitterers. In a project with GDI Switzerland we have used prominence in Wikipedia to identify the most influential people in the (English speaking) world. Wikipedia’s notability criteria are a robust mechanism to filter out the most notable 800,000 people. We have then constructed the network among these 800,000 people by linking two people, if their Wikipedia pages are mutually linked. (We call this a bi...
