Unmatched count
In psychology and social research, unmatched count, or item count, is a technique to improve through anonymity the number of true answers to possibly embarrassing or self-incriminating questions. It is very simple to use but yields only the ''number'' of people bearing the property of interest. It was introduced by Raghavarao and Federer in 1979
== Method ==
The participants of the survey are divided into two groups at random. One group (the control group) is asked to answer a few harmless questions, while the other group gets one additional question (hence the name "unmatched count"), the one about the property of interest. The respondents are to reveal only the ''number'' of "yes"-answers they have given. Since the interviewer does not know how they arrived at that number, it is safe to answer the awkward question truthfully. Due to the unmatched count of items, the number of people who answered "yes" to the awkward question can be mathematically deduced.
