This experiment is called a double-blind experiment because neither the researcher (you, in this case) nor the subjects know which sweetener they are receiving. This is done to prevent any potential bias or influence on the results, as the researcher or subject may have expectations or opinions about the sweeteners that could affect their responses. By keeping both parties blinded, the results can be more objective and reliable.
