INTRODUCTION: If you were given a blind taste test and asked to distinguish between two products, how confident do you think you are in telling the products apart? In my Biology 141 class, we did the Pepsi/Coke Challenge and that challenge was simply about giving individuals a blind taste test, and asking them to distinguish between Pepsi and Coke. There are many reasons why reasons people perform blind test. These test can be sent, smell, feel or taste. In marketing, a blind taste test is used as a tool for companies to see how they can improve their product. It is also used as a tool for companies to develop their brand. For example, many restaurants select random people to taste their food, so that they would know which dish needs more improvement. The results of these tests are not always the same. This is because there are some people who may use those products very frequently, so they are more likely to tell the difference between the two products. On the other hand there are those people rarely use the product, so they will have a harder...
