Community and volunteering
Write a short community survey
People answer a survey when they can see why each question matters. Tie it to one decision your group needs to make, word the questions neutrally, and make any demographic question optional.
What to check before distributing
Read each question aloud and ask whether the wording makes one answer sound more acceptable than another. 'Would you like more comfortable seating in the park?' is loaded because it presents the change as obviously good. The assistant should flag questions like that, but check them yourself too. Keep a demographic question only if the decision needs it, and make sure the way you distribute the survey does not collect names or emails you said you wouldn't ask for.
Using the responses
When results come in, paste the tallies into the conversation and ask for the main pattern and any notable splits. If the results are mixed, ask for a short plain description of the disagreement for your committee. Do not ask for a recommendation the data cannot support.
