How can I structure this question to check for availability bias? 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?
it seems that you can use randomization of options to decrease bias. That is, present every respondent with multiple choices but in completely random order.
Also, bias might be directly tested on two groups, say A&amp;B.
Only difference will be the order of available answers.

This manual seems to be very helpful: Handbook of Survey Research, Ch.9 Question and Questionnaire Design
