Answer 1

The growing popularity of decaffeinated coffee among Jenae's co-workers, under the false impression that it gave them extra caffeine, is an example of the placebo effect.

Step-by-step explanation:

The growing popularity of decaffeinated coffee among Jenae's co-workers, under the false impression that it gave them extra caffeine, is an example of the placebo effect.

The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In this case, Jenae labeled the decaffeinated coffee as having caffeine, creating the belief that it would provide an extra boost of energy. As a result, her co-workers experienced a placebo effect, believing that the coffee helped them focus on their work.
