Name: Dr. Pepper Taste Test
Abstract: This experiment was designed to see if participants could distinguish the difference between diet and regular Dr. Pepper. Two hundred and seventy-six participants were asked to taste diet and regular Dr. Pepper. They were either given diet, regular, or no soda before they took the taste test (ie, “pre-soda”). Some participants were told what kind of pre-soda they were given while others were not to see if it impacted their ability to tell the difference between diet and regular Dr. Pepper.
