I like this consultation by the Italian government, on constitutional reform. It’s a technical issue, so they’ve provided two options – a five minute questionnaire, and a twenty minute one.
The five minute questionnaire says:
“You don’t need to be an expert to respond, but we recommend you read the glossary of terms”
The twenty minute version says:
“This questionnaire goes into greater depth. It requires a slightly deeper level of understanding than the first questionnaire, but it is still open to all”.
