Thread: Preventing workers from accepting HITs over multiple batches?

  1. #1

    Preventing workers from accepting HITs over multiple batches?

    I have a survey that I'm interested in posting to MTurk. The catch is that I want to post several different versions of it, but only allow Turkers to take it once. Thus, once a Turker has taken, say, variation #2, I want to prevent them from taking variations #1, #3, and #4.

    Also, I want to post all of these HITs at the same time, so the solution posted at http://turkernation.com/showthread.p...instructions)& doesn't quite fit the bill.

    Finally, I'm hoping for a relatively high response rate, so I want to avoid using qualification tests (if possible), as I've heard that requiring a qualification test (no matter how trivial) for a single HIT will severely depress response rates.

    Any help or suggestions would be very much appreciated. Thanks!

    Eschew obfuscation, espouse elucidation. Batch HITs for newbs. 1000 req'd. 5000 req'd.
