Creating Compensation HITs for Mechanical Turk Workers

Posted by TurkPrime on Nov 15, 2018 10:00:00 AM

At TurkPrime, we advocate for requesters to treat workers fairly when posting HITs on Amazon’s Mechanical Turk (MTurk). Workers are, after all, the people who make the research possible. Sometimes situations arise in which an MTurk worker is unable to receive payment, despite having completed a survey. Below are two common scenarios in which a worker may not be paid, despite completing a survey:

Running Dyadic Studies on Mechanical Turk using TurkPrime

Posted by TurkPrime on Nov 8, 2018 10:01:50 AM

Studying pairs of people (e.g., married couples, friends, coworkers, etc) is becoming increasingly commonplace in the social and behavioral sciences. Online participant populations, such as Mechanical Turk and other online panels, can potentially serve as a rich source of dyadic participants. However, conducting dyadic research online also faces multiple challenges that need to be overcome in order to obtain high quality results. This blog post will outline some of the challenges of running dyadic studies online, as well as the ways our MTurk Toolkit can best be used to run a dyadic study, with recommendations for best practices based on our experience. Using the methods outlined in this blog, researchers have been able to successfully run numerous dyadic studies using the MTurk Toolkit.

TurkPrime Tools to Help Combat Responses from Suspicious Geolocations

Posted by Jonathan Robinson on Aug 15, 2018 2:51:00 PM

Last week, the research community was struck with concern that “bots” were contaminating data collection on Amazon’s Mechanical Turk (MTurk). We wrote about the issue and conducted our own preliminary investigation into the problem using the TurkPrime database. In this blog, we introduce two new tools TurkPrime is launching to help researchers combat suspicious activity on MTurk and reiterate some of the important takeaways from this conversation so far.

Concerns about Bots on Mechanical Turk: Problems and Solutions

Posted by Leib Litman on Aug 10, 2018 6:46:00 PM

Data quality on online platforms

When researchers collect data online, it’s natural to be concerned about data quality. Participants aren’t in the lab, so researchers can’t see who is taking their survey, what those participants are doing while answering questions, or whether participants are who they say they are. Not knowing is unsettling.

New Feature: Exclude Highly Active Workers

Posted by Leib Litman on Dec 15, 2017 12:30:00 PM

Some workers on MTurk are extremely active, and take the majority of posted HITs. This can lead to many issues, some of which are outlined in our previous post. Although MTurk has over 100,000 workers who take surveys each year, and around 25,000 who take surveys each month, you are much more likely to recruit highly active workers who take a majority of HITs. About 1,000 workers (1% of workers) take 21% of the HITs. About 10,000 workers (10% of workers) take 74% of all HITs.

Best recruitment practices: working with issues of non-naivete on MTurk

Posted by Leib Litman on Dec 8, 2017 3:59:00 PM

It is important to consider how many highly experienced workers there are on Mechanical Turk. As discussed in previous posts, there is a population pool of active workers in the thousands, but this is far from exhaustible. A small group of workers take a very large number of HITs posted to MTurk, and these workers are very experienced and have seen measures commonly used in the social and behavioral sciences. Research has shown that when participants are repeatedly exposed to the same measures, this can have negative effects on data collection, changing the way workers perform, creating treatment effects, giving participants insight into the purpose of some studies, and in some cases impact effect sizes of experimental manipulations. This issue is referred to as non-naivete (Chandler, 2014; Chandler, 2016).

Strengths and Limitations of Mechanical Turk

Posted by Leib Litman on Nov 20, 2017 11:12:00 PM

Hundreds of academic papers are published each year using data collected through Mechanical Turk. Researchers have gravitated to Mechanical Turk primarily because it provides high quality data quickly and affordably. However, Mechanical Turk has strengths and weaknesses as a platform for data collection. While Mechanical Turk has revolutionized data collection, it is by no means a perfect platform. Some of the major strengths and limitations of MTurk are summarized below.

Demographic Consistency Over Time on Mechanical Turk

Posted by TurkPrime on Apr 12, 2016 12:15:00 PM

Problem

Ever wonder if workers are being honest with you when they answer a survey? Or, if you specify that your study should be taken only by Women, whether some workers take the study even though they are not women?
