But I could use your help. I have constructed an online survey displaying photos of people, and I need respondents to tell me whether these people are smiling, frowning or have neutral expressions. There are over 170 questions, but they are randomized, so even if you only manage to answer a few (and then close the window), it still would help a lot!
I can’t tell you what the idea is just yet, because it might spoil how you answer the questions. More information to follow, once enough people have answered the survey.
