2. Everyone has taste preferences. Most people claim to be able to tell the differences between "their" brand and other nonpreferred brands.

Ice cream is usually sold as store - brand, premium, or super-premium, and difference is supposed to be the quality of the ingredients. You buy several gallons of vanilla ice cream, place small scoops into plain paper cups, and then ask different groups of people (15 people per group) to rate the taste of the ice cream using an interval rating scale from 1 (bad) to 7 (great).
