"A Pigovian tax solution (for now) for review/publication of studies that use M Turk samples"

Environmental Economics

I'm not sure where the Pigouvian tax comes in, but Dan Kahan: I often get asked to review papers that use M Turk samples. This is a problem because I think M Turk samples, while not invalid for all forms of study , are  invalid for studies of how individual differences in political predispositions and cognitive-reasoning proficiencies influence the processing of empirical information relevant to risk and other policy issues.

Save a Sample could save a lot of space in architects' offices

Green (Living) Review

When I had an architectural practice I also had a sample room, full of plastic laminate and wood samples and paint chips, steel shelves covered in stuff. When I closed my practice it seemed like I put a truckload of samples out on the curb, waiting to go to the dump. Now architects can find a lot more information on the internet and do not need the rows of Sweets and other catalogues, but they still need samples.

An additional sample the size of the average of DMT's versions one, three and four will cost about $1000 (where each is about n = 200). But the money cost of an additional adding up treatment could be high, especially if the surveys are fielded on a high quality survey sample as in Chapman et al.
