Most 1000minds surveys take about 10 minutes on average. However, how long a survey takes depends on how many attributes and levels you specify in your survey, and how many additional questions you include, e.g. about people’s socio-demographic characteristics. 1000minds has some smart features for limiting the number of questions people are asked without compromising the power of the analysis. For example, you can make some or all of the attributes optional so each survey participant can choose whether they are personally relevant for inclusion in their survey.
