Cola Preference: Branding Sways the Brain

Think Taste Determines Your Favorite Cola? Your Brain Knows Better

First, the researchers asked 67 participants if they had a preference between Coke and Pepsi.

Next, they conducted blind taste tests of the two colas. Some participants didn't favor the cola they had said they liked best.

In a second experiment, the researchers gave subjects a choice of two cups, one of which was labeled either "Coke" or "Pepsi." The second cup was unlabeled, but the participants were told that it could contain either Coke or Pepsi.

The participants who were given a Coke cup and an unlabeled cup clearly preferred the Coke cup. But participants who were given a Pepsi cup and an unlabeled cup did not have a strong preference for one or the other.
The results of these two experiments show that labeling can influence personal preference.

Sadly, I was swayed by the brand too at one time.

Coke is my coffie Its 8:30 am here, and Im on my second glass of the morning. Gotta have my COKE.

Coke is my choice, however when I heard it could eat rust off of a car engine, I must admit it scared me a little bit.
