The survey would say "Based on your previous answer of xxxxxxx, how do you feel about yyyyy." The survey customized later questions based on your answers to earlier questions. This is a good thing. If you felt strongly about something, they would ask deeper questions to find out why.

I think it was extremely well done and the AI built into the survey was surprisingly good.

I had a friend who used to do survey analysis. Data analysis is where surveys get expensive. Yes, they could have sent it to every member, but random survey being representative of an entire group is a well proven procedure. The problem comes in asking the right questions, giving respondents the latitude to truly express their feelings and having the ability to interpret the results.

Again, in a 20 minute survey, I only thought 1 question didn't allow me to correctly express my thoughts but the frequent essay answers let me expand on that.
