Run a taste test. Compare Pepsi vs. Coke, or bottled water vs. tap, or an expensive bottle of wine vs. the boxed stuff. Discuss participants’ level of knowledge and surprise.

Answer and Explanation:

I carried out the taste test with the members of my family, where everyone, with their eyes closed, had to taste pepsi and coke, tap water and bottled water, a bottle of expensive wine and a bottle of ordinary wine. After drinking from each pair, the participants had to express their considerations about each drink and say which was their favorite.

Regarding Coke vs. Pepsi the result was the most surprising. Among the 10 participants, 6 failed to recognize the products and chose pepsi as the drink that tasted the best. The surprising thing is that these participants had previously informed that they did not like Pepsi, which shows that the visualization of the product interferes with the reception of the product by the consumer.

Regarding tap water and bottled water the result was as expected. All participants showed preferences for bottled water, stating that tap water had a strong flavor from chemicals, such as chlorine, used in it.

Finally, the test with expensive wine and cheap wine had well balanced results and most participants were surprised by the taste of cheap wine, stating that they would drink again without any problem.
