I'm preparing a survey right now and one of the questions I'm looking to answer is: How much does availability bias effect the decision making process for [given behaviour]?
My question is: What's the best way to structure a survey question, or set of questions to test for this heuristic?
My current thinking is that I shouldn't mention specific options a respondent may select, because doing so will prime the respondents.
i.e. I can't mention specific detergent brands and then ask "Which detergent brand are you most likely to buy this month?", as that data won't be valid.
But the possible options a respondent might give if the question is completely open are endless.
Does anybody have any experience in this type of survey and can lend some insight?
