Incidence Rate: The Recruitment Cost Multiplier
Incidence rate is the fraction of people who pass your screener. In UX research, a 5% rate means screening twenty people to interview one. Teams often forget to pre-filter panels by demographics they already know, burning budget on obvious rejections.
