Thanks for accepting the HIT. "How many species?" is a short psychological study
investigating how people make guesses on the basis of limited information. It involves
the following steps:
- We ask for demographic information (not connected to your Amazon ID)
- The study then explains the guessing game. You will need to pass a short test to
check that you understand how the study works.
- Next comes the experiment itself.
- At the end, we'll give you the completion code you need to get paid for the HIT.
Total time taken should be about 15-20 minutes. Please don't use the "back" button on
your browser or close the window until you reach the end and receive your completion code.
This is very likely to break the experiment and may make it difficult for you to get paid.
