I don't know if I am right, but for me, the "neutral" option depends on the number of users : - If we don't have enough user to reach a statistical significance (let's say less than 100 users) for our survey, we should add a "neutral" option. The users who don't have any idea can bias the survey. - Now if we have enough user to reach a statistical significance (200-300+ users), we can force them to choose because they should give a random answer. That mean if my scale is between 1 and 4, I should have the same number of users that answer 2 than those who answer 3. If this case happens, then I can suppose that users don't really have idea about the answer. Otherwise, they might have preferences and it shouldn't be biased because it is be statistically significant. What do you think? ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)! To post to this list .......
