Competent and Reliable Scientific Evidence in NAD Decisions

Annie Ugurlayan
Assistant Director, Communications

An overview of the advertising self-regulatory system will be presented. Over the last two decades, a number of technical issues that arise in claims support have challenged the NAD in its decision-making. Some of these issues include what to do with no preference/difference counts, how to handle ratio or multiplicative claims and count-based claims in general, power, and how to evaluate equivalence. We will explore a number of NAD cases that touch on these issues, some of which have now been addressed in the ASTM Claims Guide.
