We Don’t Need Uber
“The experiences of that city is instructive: Austin did not immediately fall back into the clutches of evil taxi companies. Instead, the vacuum Uber and Lyft left was filled by local startups and nonprofits such as Fasten, Ride Austin, Fare, Wingz, Arcade City, and the Austin Underground Rideshare Community. Getting a ride in Austin today isn’t any different than it was before Uber and Lyft left town. Same drivers, same riders, same smartphones, same traffic.”

“He’d absorbed so much pressure, so much vitriol, and so many attacks—he assured people that it was possible to go beyond the pain barrier.”
Voting paradoxes explained
With almost every election comes a push from some to change the way Americans elect their representatives in government. The problem is, there’s no perfect method of voting. The Exploratorium has produced a video that looks at how different voting methods fail in different ways, including through the spoiler effect, cyclic preferences, and the failure of monoticity. In short, every potential way of voting allows for some irrational outcome to arise out of the choices of individuals. So says Kenneth Arrow, who came up with Arrow’s impossibility theorem, explained in more layman’s terms here on Marginal Revolution.
Paradoxes such as the above have been known for centuries. What Arrow showed is that no decision mechanism can eliminate all of these types of paradoxes. (n.b. Arrow’s theorem actually applies to any mechanism for aggregating any rankings not just voting and not just preferences.) We can tamp down some paradoxes but only at the expense of creating others (or eliminating democracy altogether.)
More generally, what Arrow showed is that group choice (aggregation) is not like individual choice.
Also, think for a minute about how Arrow’s impossibility theorem might affect what Facebook, Twitter, Pinterest, Digg, and hundreds of other media companies and apps are trying to do in aggregating the world’s news and information by social media “voting”.

Trump supporters are living in a reality shaped by television, says a Harvard professor
Donald Trump’s enduring popularity has surprised just about everyone. And no wonder, argues Harvard political theorist Danielle Allen. Half the nation consistently fails to understand the other half because the US is a nation divided between those who watch the news and those who read it. The conversations on the two different media are starkly different, she says, making it increasingly difficult for those who read news to understand the perspective of those who watch it, and vice versa.
Those who read news and analysis are largely out of touch with the narratives that shape TV news, and the viewers who watch it. “My hypothesis is that, as of summer 2015, the conversations in TV and radio land were barely visible within text-based journalism,” she wrote in a Washington Post article on the subject.
Trump, Allen says, is a television candidate.
“He was already in the world of television conversation. That’s the genre that he fits in and that’s what he appeals to,” she says. “You have to switch hats from the expectations and standards of a reading context to the expectations and standards of a television-watching context. That’s all you need to know for understanding why he’s appealing.”
Allen believes that Trump’s anti-political correctness rhetoric makes far more sense in the context of TV, where there’s often criticism of elites and professional sectors.
Television also tends to have a greater focus on the potential dangers of crime and terrorism than print media. “TV news spends a lot more time on chasing bad guys and reporting on bad guys than print media does,” says Allen. Indeed, studies have shown that those who watch a large amount of TV are more likely to feel a greater threat from crime, and that the crime shown on TV is more violent and dangerous than real-world crime.
Not only does Trump better fit the narratives that often shape TV news, he also suits the language of television. Allen believes that the linguistic complexity of TV news is several grades below that of print news. And so Trump, whose speeches are at a fourth-grade level, is quite literally speaking the language of television.
Trump knows his supporters are not reading erudite columns on politics, and so he consciously presents himself as a TV candidate, argues Allen. He’s shown disdain for the rhetoric and practice of print media and, when he first launched his campaign, his website had no policy papers on it. “All it had on it were short video statements from Trump,” she says. “He knew he was after a watching audience, not a reading one.”
In general, she says, the divide between watching and reading news is sharp. “People are consuming stuff either in a written or in a TV form and, for the most part, it’s not a matter of going back and forth between them,” she adds.
The divide is so strong that Allen believes it’s possible to predict someone’s politics based on whether they read or watch the news. “That’s roughly the same as saying that people with college degrees are more likely to support Clinton and people without them are more likely to support Trump,” she adds.
To those who find Trump reprehensible, it might seem the only possible explanation for his popularity is that his supporters live in a different reality. Allen’s argument gives credence to this theory. Trump supporters live in a world shaped by television discussions, not print ones. The only way to understand this alternate reality is to start watching more TV.

Constructive Interference – Hypersonic & Plebian Design
I have always loved moire patterns, like when you drive under a bridge and see two fences visually interacting, or a set of grates. I’d love to see this piece in person.
Created as a collaboration between Hypersonic and Plebian Design, Constructive Interference is a sculpture designed to engage passer-bys using the wonder of moire patterns. Installation is composed of two large patterned sheets of steel, designed to create a rapidly changing visual interference effect as viewers pass by.
