Who is working for Amazon Mechanical Turk?

These experiments delve into the lives of Amazon Mechanical Turk workers. Following the logic of the platform, workers have been employed for a small fee and asked to give a glimpse of their private lifes. Unlike the typical use of the platform, the submitted data prompt reflection on hidden labor, material quality, and ways of rebelling against a system on the verge of ethics.

The ever-growing use of platforms such as Amazon Mechanical Turk, allow large groups of individuals to participate in creating, tagging and describing data.
Introduced by Amazon in 2005, Mechanical Turk is named after an 18th century “automatic” chess-playing machine, which was handily beating humans in chess games. Of course, the robot was not using any artificial intelligence algorithms back then. The secret of the Mechanical Turk machine was a human operator, hidden inside the machine,who was the real intelligence. 1

Today, Amazon Mechanical Turk is a marketplace for tasks that cannot be easily automated, which are then fulfilled by human users. Such tasks, mainly involve the creation of datasets: collections of data that act as pedagogical learning material when dealing with Artificial intelligences, most specifically, machine learning systems. Current Artificial intelligences are in fact able to "learn” to execute such tasks by simply repeatedly analysing large numbers of labelled examples and counterexamples.
Such data is analysed and processed by workers on platforms like Mechanical Turks. But little is known about these individuals that complete these tasks.

“The view is partially blocked by a large hedge/bush of some sort. There are large deciduous trees off in the distance, and what appears to be an overcast sky. In the far right window pane there is a flowering bush with pink flowers.”

On July 02, 2022 I uploaded 200 images on Amazon Mechanical Turkand I asked the workers on the platform to describe what they saw. The description above is one of the hundreds that I received in less than an hour.

The images that have been described are a result of the same process. On June 16, 2022, I started this experiment by asking the workers at Amazon Mechanical Turk to send me a photo of their view out of the window and the city they live in for $0.20.

As organisations use Mechanical Turk to create datasets, in these experiments more private dataseta have been created. Following the logic of the platform, for a small fee workers have been asked to show a glimpse of their private life, their view close to their desk, their working station. At the limit of ethics and labour exploitation I asked myself whether this is an acceptable approach to use in research and in general, if employing random workers around the world is the ideal practice to shape future artificial intelligences.

While both tasks were performed, the material collected varied considerably: from blurred photos to details of curtains, from landscapes to computer screenshots.

The same consideration can be made with the texts collected. Some descriptions are lengthy, others are short, some are tags, others instead are just typos. Following the idea that when talking about a technology one has to place oneself within it, becoming a 'Requester' on Amazon Mechanical Turk allowed me to find out more about how the system works, the review process and the quality of the data collected.

Although much is documented about the demographics of the platform and the fact that different payments do not affect the quality of the results, these 'results' are rarely visible. Most of the data collected did not reflect the assigned task. Many results were gibberish, or when asked to upload a photo, these were often desktop screenshots, stock images, or photos on the computer. These rebellious approaches to the platform allow workers to collect their rewards easily and can be ignored by requesters. For this reason, such datasets are shown in their entirety on this site.

“Information has always had geography. It is from somewhere; about somewhere; it evolves and is transformed somewhere; it is mediaxted by networks, infrastructures, and technologies: all of which exist in physical, material places”. 2

Datasets are no exception. The information they carry is a reflection of time, politics and geographical contexts.
Although, in the past years, there has been a growing attention of bias studies in the field of machine learning, there is still a general disinterest for the ones carried by the hidden geographies of datasets. Consequentyl, a central focus is on the geographies of Amazon Mechanical Turk. Not necessarly on the demographics of its workers, but rather on the different places where data is annotated and created.

Views from outside the window

I asked the workers at Amazon Mechanical Turk to send me a photo of their view out of the window for $0.20. Here are the photos I received and the city they were sent from.

Before creating an account on the platform, I watched a couple of YouTube videos and read on Reddit how to set up tasks. Most of the examples and discussions I encountered were about machine learning and the amount of money you can earn on Mechanical Turk, and what is the right payment per task. On average, Amazon Mechanical Turk pays between $1 and $6 per hour.

Since I intended to collect photos of the view from workers' windows, I had to structure the task and link it to a Google form. Amazon Mechanical Turk does not allow photos to be uploaded directly and this is one of the most common approaches suggested on Reddit. A Google form allowed participants to upload a photo, write their city of origin and their Amazon Mechanical Turk ID. This way, after completing the questionnaire, they could receive a password to enter into MTurk to get the reward. With the first experiment, I collected 203 pictures. The initial goal was 100. More than 50% of the images did not comply with the request. In some cases these were broken files, in others desktop screenshots, photos of animals or stock images. Quite a few entries were duplicated to collect extra rewards.

An attempt at exhausting a dataset

As in the broken phone game, I repeated the process several times. I uploaded the pictures received from the first task into the platform and asked the new workers to describe them. I then took these descriptions and asked new workers to draw a picture of them.

As an attempt to see how information gets lost, some drawings vary considerably from the initial image.

Some outputs took a romantic direction:

In other cases, probably being used to tagging datasets, many descriptions captured only some objects in an image, and in some cases the drawings became texts.

Views of the working desk

I asked the workers at Amazon Mechanical Turk to send me a photo of their working setup. Here are the photos I received and the city they were sent from.

After more than one year from the first experiment, I logged into the platform this time asking for photos of work desks, giving this as an example:

This is the first contribution I received.

Again, I asked for 100 images and collected 140 at the end, where the extra ones were mainly the example image I provided. By default, Amazon Mechanical Turk automatically approves submissions after a period of three days. This is probably why most of the material submitted does not comply with the task. Quickly completed tasks in order to collect a reward that is hopefully not checked. With a dataset of a few hundred images, I can check each entry one by one, and in those three days I can reject entries that are 'wrong' by selecting the specific entry and writing a few words in a textarea.

The sample image, or screenshots of it appear multiple times as submissions.

However, the submitted material remains with me. I can still use it and the additional, but inaccurate, data I collect is free labour. The review process does not seem to be transparent. For all the assignments I have refused so far, no worker has ever replied to me asking for an explanation. I therefore wonder how many institutions exploit this system, refusing payment but continuing to collect tagged data for free. At the same time, if usually a third or half of the data collected is junk, where does this random content end up?

Opinions of the workers

What do you like and detest about working for Amazon Mechanical Turk? Why do you do it? Please share your honest feelings and opinions on the platform.

This time I repeated the task twice, by asking what are the feelings and opinion of the workers on the platform. The first time it was open to all workers on the platform, and the second time only to Mechanical Turk "Masters."

Mechanical Turk
“Mechanical Turk has built technology which analyzes Worker performance, identifies high performing Workers, and monitors their performance over time. Workers who have demonstrated excellence across a wide range of tasks are awarded the Masters Qualification. Masters must continue to pass our statistical monitoring to retain the Mechanical Turk Masters Qualification.”

The hiring of Masters involves a different fee charged by Mturks, which is $0.005 compared to $0.040.

In less than an hour, the first part of the new task was completed. In contrast, after 3 days I closed the task for "masters" only with only 17 submissions. The quality of these entries is definitely higher, with responses such as:

“On one hand, mturk changed my life. I have C-PTSD and find public places too noisy and stressful. I was on the verge of becoming completely homeless but went back to working on here (I previously worked a lot on here when in college but then took a break). It now gives me a chance to earn enough money to survive. On the other hand, it's a terrible way to make a living. It's not stable and can be stressful. I have found that working on other platforms and bouncing back and forth between them helps so there isn't as much down time waiting for work”.

However, it is clear that there is a lack of such workers. In addition, as already commented with the previous exercise and description above, several workers have complained about the unexplained rejections that often occur in the platform.

Lacks any ability to truly hold requesters accountable. For the pay they offer, to unreasonable rejections. Amazon plays no role in defending the worker and leaves it up to us to just deal with it. Can try sending messages to requesters but often ignored. That includes wasting an hour on work to have it crash due to the requesters faulty software. I really liked AMT years ago when I first started working for them. However, over the last year or so, this platform has really gone downhill. The hits are not worth my time. Sometimes they only pay a penny or so for work that is over five minutes long! Also, the rejecters seem to randomly reject work. I recently spent about 8 minutes explaining my response to a chatbot conversation, only to get rejected. I have no idea what they wanted. I have a master's, so I can get some good hits. However, these unfair rejections are really starting to add up, and I am worried I will lose my master's status once my rejection rate goes below 99%. What really hurt my rate was a "mass rejection" of 10 hits. It turns out that there was a glitch (I read it on MTURKOPTICON), but they would not reverse the rejections. That was so unfair when it was their fault.

Trying to work for Amazon Mechanical Turk

I am desperately trying to create a worker account to earn back what I have spent on the platform.
