On Monday 1 August Justin Wolfers flipped a coin. Heads he would use Twitter that day, tails he would not. It was heads, so he got to tweet for the day. On Tuesday, when the coin landed on tails, he wasn’t so lucky. Wolfers is going to be determining his Twitter engagement this way until the end of October. But what’s the point?
Well, Wolfers is an economist and he’s conducting a randomised trial to see whether using Twitter benefits him or not. He announced his experiment on his Freakonomics blog on 13 July: “I’m a long-time Twitter sceptic. It’s difficult for an economist to see a 140 char lmt as a ftr.” Wolfers started using Twitter in mid-July, and gave himself a grace period to figure it out before he began the experiment proper.
In his initial blog post Wolfers proposed tracking three variables: his distraction, his influence and how informed he was. He’s since stated: “I think Twitter may have (an) impact beyond my productivity. I’m now also convinced it’s worth tracking my anxiety (yes, that damn debt-ceiling debate), as well as my feelings of being engaged (ditto).” But he hasn’t yet detailed how he’ll be measuring each of these variables; we’ll have to wait for his methodology to be revealed.
Wolfers has already drawn several observations from his Twitter usage. Number 11 was: “I’m convinced that Twitter is essential for journalists. I remain sceptical that it is important for economists.” He’s not wrong on the first one – you wouldn’t be reading this story if this journalist hadn’t found out about the grand Twitter experiment via, well, Twitter.
Thing is, there’s an important caveat in the way Wolfers designed his trial. “If the coin comes up heads, it doesn’t necessarily mean that I’ll tweet, just that it will be a Twitter-aware day. I’ll consume the stream, and tweet away if I feel the need. Tails, and I’ll simply tweet “Tails, goodbye”, close the stream (unless I need it for research) and then resist the urge to tweet for the rest of the day.”
Seeing as he’s already committed to using Twitter (if he needs it for research), the social-media platform is of some importance after all – even to economists. DM

No, not really. But now that we have your attention, we wanted to tell you a little bit about what happened at SARS.
Tom Moyane and his cronies bequeathed South Africa with a R48-billion tax shortfall, as of February 2018. It's the only thing that grew under Moyane's tenure... the year before, the hole had been R30.7-billion. And to fund those shortfalls, you know who has to cough up? You - the South African taxpayer.
It was the sterling work of a team of investigative journalists, Scorpio’s Pauli van Wyk and Marianne Thamm along with our great friends at amaBhungane, that caused the SARS capturers to be finally flushed out of the system. Moyane, Makwakwa… the lot of them... gone.
But our job is not yet done. We need more readers to become Maverick Insiders, the friends who will help ensure that many more investigations will come. Contributions go directly towards growing our editorial team and ensuring that Daily Maverick and Scorpio have a sustainable future. We can’t rely on advertising and don't want to restrict access to only those who can afford a paywall subscription. Membership is about more than just contributing financially – it is about how we Defend Truth, together.
So, if you feel so inclined, and would like a way to support the cause, please join our community of Maverick Insiders.... you could view it as the opposite of a sin tax. And if you are already Maverick Insider, tell your mother, call a friend, whisper to your loved one, shout at your boss, write to a stranger, announce it on your social network. The battle for the future of South Africa is on, and you can be part of it.
