Sorry about that, I neglected to write the reasons on the website. If you try to go back to the website, the explanation will be there if you've already participated. If not, the webpage has the reason after you complete the study.
If you finished, please do not publically post anything that hints at the reason as it will skew results. If you have any suggestions or comments please email me at email@example.com
The results will be available sometime in the next week (I'll post here when they are).
Thanks for participating for those who already have, and those who haven't, click on the link!
