Limited individual attention and online virality of low-quality information | Nature Human Behaviour
Social media are massive marketplaces where ideas and news compete for our attention1. Previous studies have shown that quality is not a necessary condition for online virality2 and that knowledge about peer choices can distort the relationship between quality and popularity3. However, these results do not explain the viral spread of low-quality information, such as the digital misinformation that threatens our democracy4. We investigate quality discrimination in a stylized model of an online social network, where individual agents prefer quality information, but have behavioural limitations in managing a heavy flow of information. We measure the relationship between the quality of an idea and its likelihood of becoming prevalent at the system level. We find that both information overload and limited attention contribute to a degradation of the market’s discriminative power. A good tradeoff between discriminative power and diversity of information is possible according to the model. However, calibration with empirical data characterizing information load and finite attention in real social media reveals a weak correlation between quality and popularity of information. In these realistic conditions, the model predicts that low-quality information is just as likely to go viral, providing an interpretation for the high volume of misinformation we observe online.

The Twitter presidency is getting old, according to a new voter survey | Ars Technica
"They hate that I can get the honest and unfiltered message out," Trump tweets.
There's at least one definition of President Donald Trump that we can all agree on—he's the tweeting president.
Unlike his predecessor, Trump has provided the public with an unfiltered look at the chief executive's immediate thoughts, inventing a new word along the way. His volatile tweets have derided his own staff, the public, and even overseas political leaders. Twitter also serves as Trump's public forum, where he blocks people critical of him. And he uses the micro-blogging service as his own personal media outlet. Tuesday night, for example, he tweeted that he would nominate Christopher Wray to replace James Comey as the FBI director.

Kyrie Irving's Idiotic Flat Earth Belief is Catching On - Rolling Stone
Cleveland Cavaliers star's misguided rejection of science is having an unfortunate impact
Earlier this year, Cleveland Cavaliers superstar Kyrie Irving revealed that he believes the earth is flat. While such a claim can easily be disproved by centuries' worth of science, it generated enough coverage for the likes of Bill Nye the Science Guy and Neil deGrasse Tyson to weigh in on the subject. And yet, some young, impressionable fans believe Irving over their science teachers, NPR reports.
