What can researchers do to address anomalous survey and experimental responses on Amazon Mechanical Turk (MTurk)? Much of the anomalous response problem has been traced to India, and several survey and technological techniques have been developed to detect foreign workers accessing US-specific surveys. We survey Indian MTurkers and find that 26% pass survey questions used to detect foreign workers, and 3% claim to be located in the United States. We show that restricting respondents to Master Workers and removing the US location requirement encourages Indian MTurkers to correctly self-report their location, helping to reduce anomalous responses among US respondents and to improve data quality. Based on these results, we outline key considerations for researchers seeking to maximize data quality while keeping costs low.

AbstractIn this study, we investigate the attentiveness exhibited by participants sourced through Amazon Mechanical Turk (MTurk), thereby discovering a significant level of inattentiveness amongst the platform’s top crowd workers (those classified as ‘Master’, with an ‘Approval Rate’ of 98% or more, and a ‘Number of HITS approved’ value of 1,000 or more). A total of 564 individuals from the United States participated in our experiment. They were asked to read a vignette outlining one of four hypothetical technology products and then complete a related survey. Three forms of attention check (logic, honesty, and time) were used to assess attentiveness. Through this experiment we determined that a total of 126 (22.3%) participants failed at least one of the three forms of attention check, with most (94) failing the honesty check – followed by the logic check (31), and the time check (27). Thus, we established that significant levels of inattentiveness exist even among the most elite MTurk workers. The study concludes by reaffirming the need for multiple forms of carefully crafted attention checks, irrespective of whether participant quality is presumed to be high according to MTurk criteria such as ‘Master’, ‘Approval Rate’, and ‘Number of HITS approved’. Furthermore, we propose that researchers adjust their proposals to account for the effort and costs required to address participant inattentiveness.

The United States Supreme Court declared in 1976 that deliberate indifference to the serious medical needs of prisoners constitutes the unnecessary and wanton infliction of pain…proscribed by the Eighth Amendment. It matters not whether the indifference is manifested by prison doctors in their response to the prisoner’s needs or by prison guards intentionally denying or delaying access to medical care or intentionally interfering with treatment once prescribed—adequate prisoner medical care is required by the United States Constitution. My incarceration for four years at the Oakdale Satellite Prison Camp, a chronic health care level camp, gives me the perspective to challenge the generally promoted claim of the Bureau of Federal Prisons that it provides decent medical care by competent and caring medical practitioners to chronically unhealthy elderly prisoners. The same observation, to a slightly lesser extent, could be made with respect to deficiencies in the delivery of health care to prisoners of all ages, as it is all significantly deficient in access, competencies, courtesies and treatments extended by prison health care providers at every level of care, without regard to age. However, the frailer the prisoner, the more dangerous these health care deficiencies are to his health and, therefore, I believe, warrant separate attention. This paper uses first-hand experiences of elderly prisoners to dismantle the tale that prisoner healthcare meets constitutional standards.
