Hi, I'm Stefan, a PhD student from Chemnitz University of Technology (Germany) and joined TV as a requester. I've done a study on mTurk in the past that unfortunately didn't go as expected as most of the submissions were from bots giving random answers. I joined this forum to see if some of the workers can give me tips on how to improve my study to ensure that only humans participate. I've improved it a bit and will make a separate post in the next days. I would be very happy if some of you workers could review it. Thank you!
