Mechanical Turk

Category: Cool-Stuff

Can you explain what Mechanical Turk is all about? A friend of mine uses it to make money by doing small jobs, but I've heard some people say it's more like slave labor. What's the deal with Mechanical Turk?

Mechanical Turk

What Is Mechanical Turk?

Mechanical Turk (MT) is an online phenomenon that emerged in 2005 as the brainchild of Amazon Web Services. It was originally set up to help complete their in-house tasking needs, however, it soon became apparent that thousands of companies around the world could benefit from this web application.

Mechanical Turk in a nutshell is virtual outsourcing. The MT economy is based on the exchange of Human Intelligence Tasks for small monetary payments. The people who create the HITs are called Requesters. Requesters usually break down complex tasks into smaller, basic tasks that can be completed by one or many MT workers. Usually these tasks include writing, data entry or online research. It is facilitated through an open Application Programming Interface (API) or through the Mturk Requestor web site.

The "Mechanical Turk" moniker comes from an "artificial artificial intelligence" project. The Turk was a machine invented in 1770, and it was promoted as a chess-playing robot that could beat the best players of the day. In reality, it was a clever hoax, concealing a human chess master inside the box. Amazon's Turk has real humans "inside the box" but they make no secret of that fact.

The Players In a Mechanical Turk Economy

As mentioned earlier there are two types of players in the Mechanical Turk economy, Requestors and Users. Requestors are made up of companies and small businesses that need simple tasks completed such as writing reviews and product descriptions, conducting online research, transcribing audio, and entering data. There are hundreds of companies that post small HIT groups semi-regularly, however, there is a smaller group of companies that post large groups of HITs on a regular basis.

Requesters can use the simple web-based interface to post HITs, or pump HITs into the MT system with the API. HIT Builder, a third-party software tool, can help Requesters build HITs en masse, by importing from database and spreadsheet applications.

The MT users (sometimes called Turkers) are the workers that claim and complete the HITs. MT users can include people from all walks of life and from all professions. Some companies select their Mechanical Turk users from local colleges and universities, while others will accept just about anyone as long as they are able to complete the HITs successfully.

Who are the Turkers? They can be bored housewives, college students who need a little extra money, or people in countries with much a lower standard of living, who are willing to accept the low rates typically offered by MT Requesters. While Requestors and Users can come from any where in the world, it's hard to tell who the workers are, because the MTurk system takes pains to provide anonymity for the workers.

Volunteers can also take on tasks via Mechanical Turk. In an effort to help find the airplane of missing adventurer Steve Fossett,
Amazon set up a Mechanical Turk project in which volunteers can view satellite photos and search for the crash site of the plane.

Praise and Criticism of the MT Economy

The cost of the Mechanical Turk exchange for Requestors is relatively inexpensive. Amazon has established a minimum bid of one cent per HIT, however, the price paid for each HITs is going to depend on its complexity and size, as well as on the Requestor who posted the HITs. Many Requestors find that HITs are a very affordable way to outsource large groups of similar tasks that are very simple to complete. Companies find the MT "task auction" model attractive because it reduces payroll costs.

While Requestors find the current price structure for HITs attractive, many of the top HITs producers think that it is basically slave labor. Requestors enjoy tax advantages and low costs in the MT exchange economy, but MT users are required to report the income that they earn from this exchange and as a result they may have to pay high self-employment tax rates. This coupled with the low payout rate makes the MT exchange less than perfect from a user's point of view. But then, nobody is forcing these self-proclaimed "slaves" to work for a pittance. The law of supply and demand is still in effect, and it usually does a pretty good job of controlling market forces.

Is Mechanical Turk creating an unfair labor situation? If you ask affluent US-based MT workers, they may say yes. But motivated Turkers in second and third-world economies may be thrilled at the chance to work for nickels and dimes, because the impact of those few extra dollars is magnified many times over.

Other virtual outsourcing services such as eLance and Rent A Coder can meet the needs of both employers and workers, but typically these sites require more technical skills on the part of the workers. Mechanical Turk tasks often require only rudimentary writing or online research skills.

I came to Mechanical Turk (MT) during the "Search for Steve Fossett" lately. When the search ended, I started looking what MT is all about and made some MT-"HITs" for Amazon's own "Askville" social networking site. MT workers are doing hours of research for Askville for a reward of 2 cents. They are lured into a competition by a "$1675 weekly reward", of which you can get a share of "$19 by only 2 answers voted Great Answer" but reliably keeps you getting enough "Great" votes by a extremely faulty voting system.

So if you worked a month for 20 bucks, this money is partially going back to Amazon itself because all you can do with that money is ordering stuff at But since you can't transfer your balance to a bank account, you probably can't get this money at all.

So MT is not only the most evil spawn of capitalism, it even falls back on highly dubious "fine print" tactics to avoid paying the workers their hard earned few cents.

EDITOR'S NOTE: Your information about payment seems to be incorrect. The Mturk FAQ says you can transfer money earned through Mechanical Turk "to your bank account or to your gift certificate balance." You can also request payment in Indian Rupees.

That's not quite true. I should have pointed that out more detailed..:) I asked MT's customer service. From their answer:

"I'm sorry, however currently funds received in your Mechanical Turk account can only be disbursed to a US checking account or in the form of a gift certificate."

You can get your money transferred to an U.S. bank account OR to India (rupee check). So if you're not an US or India resident, you can only transfer your balance to an gift certificate. But these certificates can't be transferred to the affiliates like or and you can't get online services like MP3 download for them either. You will learn this only from the fine print, most probably *after* you transferred your balance to them. At no place on MT, foreign "workers" are being warned that such disadvantages exist.

So unless you spent a whole month working all day in their treadmill for a "reasonable" balance of more than $20, shipping costs will eat up much of your salary and Amazon will get a part of what you earned back in form of sales profit. This is ridiculous, isn't it?

EDITOR'S NOTE: Okay, I see your point. You never mentioned what country you are from. Your IP address indicates that you are in or near Hamburg, Germany, so I can understand your frustration. It doesn't seem reasonable that you can't use those credits at

I live in Canada and while I would welcome getting a check for my Turking. I see gift certificates as a fair alternative for me mind you shipping to Canada is a lot easier than oversee. Anyway for me Mturk was always about subsidizing my entertainment budget to spend on things like DVD, book and electronic. I do enough to load up than I take a few month of break.

A couple of days ago I spent a while as “worker” for Mechanical Turk.

The chips are heavily stacked against you as a worker. Most of the HITs (Human Intelligence Tasks) woefully underpay the worker. And two full days later I have only gotten paid for 1 of my 11 tasks. After reading the impenetrable terms, I find that the “Requester” can arbitrarily reject my work and not pay me. He can wait indefinitely to pay me.

And can you believe Amazon reserves the right to punish you for violating anything in their policies, which they only provide in dense legalese? Explanation in plain English is limited to a few points. Certainly it does not include an explanation of how you are signing access to your bank account over to Amazon, with no further permission required to take your money, which is buried deep in the legal text.

Working for Amazon as a Mech Turk Drone is a sad place to be. It is a place of mental desolation. With egregiously poor pay and a total lack of rights Amazon runs Mechanical Turk like a PROFITABLE LITTLE PRISON WORK CAMP.

EDITOR'S NOTE: I hope you realize that Mechanical Turk is a marketplace. Workers must CHOOSE to perform tasks at a previously agreed upon wage. Don't like it? Try eLance or some other freelance site.
