You have to understand also that the questions are well crafted to elicit a predicable response. You can't ask 600 pilots to freeform a wishlist of contractual gains and expect any hope of statistical relevance. As such, the questions will be asked by non-pilots that have no clue what it is that they're asking. Historically with the kind of ALPA polling, you'll get a "agree, disagree, disagree strongly...." kind of option with maybe one fill in the blank.

In other words, the MEC has already carefully crafted the questions to drive their desired answer. SSDD. And, as mentioned above....they'll come back and insist that "this is what you asked for....we have statistically relevant polling data to prove it...".
