Is Amazon’s Mechanical Turk breaking down?

Workers are disgruntled in Amazon’s MTurk marketplace, but can they successfully demand more rights?

“Mechanical Turk” is a term first used in the 18th century to describe a device that appeared to automate chess-playing. Players believed they were playing against an automated machine, but they were actually competing against a human hidden inside of the device (see illustration below).

The name has since been applied to Amazon’s platform to offer “artificial artificial intelligence.” Created in 2005, Mechnical Turk, or “MTurk,” connects organizations with individuals (“Turkers”) to perform Human Intelligence Tasks (“HIT”), microtasks that are challenging for computers, but simple for people. For example, a human would have no issue picking an item out of a photo, but it would be very difficult for a computer. Since its inception 12 years ago, MTurk workers are responsible for the foundations of algorithms all around us, leveraged by familiar companies like YouTube and Google, but it has largely stayed under the radar.

As of 2015, it was estimated that MTurk had about 500,000 registered Turkers globally, though it’s unclear how many of those are active. Another report estimates that 500,000 tasks are available daily. As noted, companies often leverage MTurk to train their code, yet most of the tasks are repetitive and mind-numbing. Turkers may be asked to make various faces into their webcam to help an algorithm identify facial expressions. Another HIT may ask Turkers to identify dozens of materials or textures in a photo (e.g. metal, hair, water, wax). Payment terms are dictated by the party requesting the HIT, typically ranging from $0-60 per task. They are also obligated to pay 10% commission to Amazon. A research study showed that 61% of tasks offer payment of 10 cents or less. Turkers are rated based on their completed tasks and can achieve higher status, which in turn gives them access to better tasks.

Reviews, identification of “super” workers, commission structure – MTurk doesn’t sound any different from the other marketplaces in the gig economy. So what went wrong? In December 2014, timed around Christmas and posed as Christmas letters sent directly to Jeff Bezos, Turkers organized a public campaign to demand better pay and representation. HIT requesters can pay $0 for a task with no consequence. Turkers wanted Amazon to better educate requesters and the world that they are not all unskilled workers, and thus shouldn’t be paid or represented as such. Some also demanded the ability to review company requesters after completing tasks. Many others complained that they never received payment from Amazon, which was often supposedly lost during transit, but instead received the offer for Amazon credits. Amazon quickly cut off the movement by shutting down the account used by the campaign to verify Turkers. Since then, Turkers have reportedly been leaving MTurk in search of marketplaces that offer fairer pay and terms, though the magnitude is unclear due to lack of reporting on MTurk’s size.

Though Amazon’s MTurk continues to exist and has not yet failed, it’s clear that Turkers are becoming more aware of their collective power. Once isolated from one another and hidden behind MTurk’s platform, Turkers are creating forums to build networks among themselves. Amazon could have avoided the Christmas campaign and negative publicity by setting terms that gave Turkers some leverage on the platform. For example, they should have an opportunity to review companies back. One common issue on MTurk is that task descriptions may be imprecise, so they take much longer or are more complex than expected. If this happens, Turkers have no way of offering feedback to the platform. Amazon should be incentivized to improve this precision because it will lead to greater satisfaction across both parties, requesters and Turkers. They could also ban tasks with $0 compensation, even setting a floor as low as $0.10 would help Turkers to feel relatively more protected.

Alternatives are appearing that favor the workers. For example, a director competitor called Daemo has been created, that offers workers $10 per hour and increased transparency. It is gaining momentum, though it will be interesting to see if they can attract companies used to Amazon’s low rates and flexibility.

Student comments on Is Amazon’s Mechanical Turk breaking down?

  1. I’m surprised that Amazon ceded the users so easily to other platforms rather than the fixes you recommend. Perhaps the platform was not generating the value that Amazon requires of other projects. It seems like access to a crowd of individuals was much more valuable to people hiring Turks, but when the Turks acted together as a crowd, it started to detract value. It’s a little troubling what this could lead to if you play it out – that companies may look for ways to keep the Turks from being able to identify each other, coordinate, or argue for their interests. I’ll be interested to see how this continues to develop in the future.

  2. Mechanical Turk also gets into questions about the future of work as work tasks are increasingly disaggregated from traditional jobs, and we move toward platforms that focus on piece-payments rather than wages or salaries. What responsibility does Amazon or the companies using the platform have to target prices to hit minimum wage standards? Is this ultimately an end-run around the kinds of basic job quality regulations governments put in place? I love the idea of efficient pricing and flexible work, but it’s a challenge to make sure the workers aren’t exploited—and it sounds like Amazon is losing that battle while missing the opportunities for platform optimization you suggest which could also create value for both sides.

  3. What responsibility does Amazon have to guarantee a minimum wage for Turkers? I fail to see why Amazon, who is simply providing a marketplace for consenting workers, needs to handicap its marketplace by attempting to regulate with a minimum achievable wage. I see this almost as piecework in a traditional economy, those who are able to accomplish these micro-assignments most efficiently will be the most rewarded in the system, those who are unable to achieve a living wage will remove themselves from the system.
