I would have given a response for digit ratio if I'd known about the steps to take the measurement before opening the survey, or if it were at the top of the survey, or if I could answer on a separate form after submitting the main survey. I didn't answer because I was afraid that if I took the time to do so, the survey form, or my https connection to it, or something else would time out, and I would lose all the answers I had entered.
