MTurk is Reliable, Accurate and Efficient

I say this, of course, but now I’m joined by researchers who examined how well Turkers code relative to ‘experts’. And guess what?

“In the current study, MTurk workers content analyzed personally-written textual data using coding categories previously developed and validated in psychological research. These codes were evaluated for reliability, accuracy, completion time, and cost. Results indicate that MTurk workers categorized textual data with comparable reliability and accuracy to both previously published studies and expert raters. Further, the coding tasks were performed quickly and cheaply.”

This is good news as coding is a pain. Now someone needs to figure out an interface to manage coding among a wide range of people.
