TLDR
The authors presented new demographic data about the Mechanical Turk subject population, reviewed the strengths of Mechanical Turk relative to other online and offline methods of recruiting subjects, and compared the magnitude of effects obtained using Mechanical Turk and traditional subject pools.Abstract:
Although Mechanical Turk has recently become popular among social scientists as a source of experimental data, doubts may linger about the quality of data provided by subjects recruited from online labor markets. We address these potential concerns by presenting new demographic data about the Mechanical Turk subject population, reviewing the strengths of Mechanical Turk relative to other online and offline methods of recruiting subjects, and comparing the magnitude of effects obtained using Mechanical Turk and traditional subject pools. We further discuss some additional benefits such as the possibility of longitudinal, cross cultural and prescreening designs, and offer some advice on how to best manage a common subject pool.read more

Common (mis)beliefs about memory: a replication and comparison of telephone and Mechanical Turk survey methods.
TL;DR: The results of this study replicate the finding of substantial discrepancies between popular beliefs and those of experts and shows that surveys conducted on MTurk can produce a representative sample of the United States population that generates results in line with more expensive survey techniques.

Assessing the quality of ideas from prolific, early-stage product ideation
Barry Kudrowitz,David Wallace +1 more
TL;DR: A metric of three attributes to be used as a first pass in narrowing a large pool of product ideas to the most innovative: novel, useful (or valuable), and feasible (as determined by experts) is suggested.

Efforts to overcome vegetarian-induced dissonance among meat eaters.
TL;DR: It was hypothesized that exposure to a description of a vegetarian would lead omnivores to embrace dissonance-reducing strategies and four experiments supported this prediction and found that authentic vegetarians, vegetarians freely making the decision to abandon meat, consistent vegetarian, and anticipating moral reproach from vegetarians produced greater endorsement of dissonances-red reducing strategies than their counterpart conditions.

Crowdsourcing performance evaluations of user interfaces
TL;DR: MTurk may be a productive setting for conducting performance evaluations of user interfaces providing a complementary approach to existing methodologies, and three previously well-studied user interface designs are evaluated.
Journal ArticleDOI
The influence of political ideology on trust in science
TL;DR: The anti-reflexivity thesis as mentioned in this paper suggests that some sectors of society mobilize to defend the industrial capitalist order from the claims of environmentalists and some environmental scientists that the current economic system causes serious ecological and public health problems.

The Framing of Decisions and the Psychology of Choice
Amos Tversky,Daniel Kahneman +1 more
TL;DR: The psychological principles that govern the perception of decision problems and the evaluation of probabilities and outcomes produce predictable shifts of preference when the same problem is framed in different ways.

Amazon's Mechanical Turk A New Source of Inexpensive, Yet High-Quality, Data?
TL;DR: Findings indicate that MTurk can be used to obtain high-quality data inexpensively and rapidly and the data obtained are at least as reliable as those obtained via traditional methods.

On the social psychology of the psychological experiment: With particular reference to demand characteristics and their implications.
TL;DR: In this paper, the authors focus on some of the qualities peculiar to psychological experiments and point out that the demand characteristics perceived in any particular experiment will vary with the sophistication, intelligence, and previous experience of each experimental subject.

Extensional versus intuitive reasoning: The conjunction fallacy in probability judgment.
Amos Tversky,Daniel Kahneman +1 more
TL;DR: The conjunction rule as mentioned in this paper states that the probability of a conjunction cannot exceed the probabilities of its constituents, P (A) and P (B), because the extension (or the possibility set) of the conjunction is included in the extension of their constituents.

Should we trust web-based studies? A comparative analysis of six preconceptions about internet questionnaires.
TL;DR: Internet data collection methods, with a focus on self-report questionnaires from self-selected samples, are evaluated and compared with traditional paper-and-pencil methods and it is concluded that Internet methods can contribute to many areas of psychology.
