It was a day like any other. The sun had once again risen on God's green creation. There were ants in my living room. Friends were over.
The question arose, through random conversation. Can you taste caffeine in pop? If so, is there a preference?
It was then that New Jerusalem News decided to take the challenge! With the help of Chad Waldron, a first-year Psychology Student at Kalamazoo Valley Community College, the experiement shaped up mighty nice. For those of you who care about such things, here are the details.
Soda Used: Pepsi, Caffeine Free Pepsi, Diet Pepsi, Diet Caffeine Free Pepsi, Diet Coke, Diet Caffeine Free Coke
Test Subjects: Robin (28), Mikayla (9), Corina (7) , Billy (29), Chad (29), Kristen (28)
Itinerary: Subjects are given two cups, one containing a caffeinated pop, one uncaffeinated. They are then asked one of two questions; "Which do you prefer?" and "Which of these is caffeine free?" They do not know what is contained in the cups.
Intention: The intent is to discover not only if a subject can actually taste caffeine, but if the subject would prefer a caffeinated beverage to an uncaffeinated one, without knowing which is which.
Results for each subject were as follows:
Kristin preferred the taste of Caffeine Free Pepsi over regular Pepsi, She guessed wrong about which contained caffeine. She did not prefer the taste of either diet sodas, and could not tell the difference between the diet sodas, caffeine or not.
Robin Preferred the taste of Caffeine Free Pepsi and Diet Caffeine Free Coke. She guessed correctly which regular sodas contained caffeine and which diet sodas contained caffeine.
Mikayla preferred the taste of Caffeine Free Pepsi and Diet Caffeine Free Coke. She guessed wrong about which sodas contained caffeine both times, diet or not.
Corina preferred the taste of Regular Pepsi and Diet Caffeine Free Coke. She guessed correctly which regular and diet sodas contained caffeine.
Billy was given three seperate tests and asked which contained caffeine. He guessed right on all three. He was not asked which he preferred.
Chad was given three seperate tests and asked which contained caffeine. He guessed right on two and wrong on one.
Conclusion: A total of 22 tests were given. Subjects preferred the taste of uncaffeinated soda over caffeinated 2.5 to one. Subjects were able to guess which soda contained caffeine with a ratio of 3 to one. Based on that data, New Jerusalem News must conclude that subjects prefer uncaffeinated soda and can taste the difference.
