I agree with the radio talk show host who said yesterday that she doesn't like blind taste tests; it often seems, as she said, that the taste testers are trying to trip people up and make them look silly.
Once, after noticing how often I put slices of yellow bell peppers in salads, I bought a yellow pepper. This was a mistake, as I only ended up eating a small amount of it. I realized then that I only ate small bits of yellow peppers as one ingredient among many in a salad. It didn't mean I craved an entire bell pepper.
That principle sometimes applies to taste tests. Enjoying a small sample of a soda or other beverage doesn't necessarily mean you'll want to drink 20 ounces or two liters of it. Sometimes, people just crave a bit of caffeine, sweetness, or bitterness.
