Final answer:
Jordan did not see results from the sugar elimination diet because she trusted the authority of a celebrity without scientific evidence, which is a common logical fallacy called 'appeal to authority'.
Step-by-step explanation:
Jordan, who followed the advice of her favorite celebrity's social media posts to try a seven-day sugar elimination diet to improve her acne, did not see results. This experience suggests she may have fallen victim to the logical fallacy known as 'appeal to authority'. This fallacy occurs when someone assumes that a claim is true just because an authoritative or famous person said so. However, not all advice from such sources is based on scientific evidence or may not apply to everyone.
Celebrities often influence their fans, but their recommendations are not always the result of rigorous scientific research and can vary in effectiveness from person to person. Selena Gomez, for instance, has a wary relationship with social media due to its addictive nature and potential to influence thoughts and ideas undesirably. Therefore, while it's tempting to follow celebrity advice, it is essential to think critically and seek information from reliable, scientific sources when it comes to health and diet decisions.
