Are Top 50, Top 100 Lists Credible?

Every now and then some of the media houses release the Lists of top 50 desirable people, top 100 movies, top 100 celebrities etc. While some media houses conduct online polls, some more media houses go on other measures to finalize the Lists. But then, are these surveys and Lists credible? Well, some of the national media have faced allegations that they take money to publish political articles. It doesn't mean the same strategy is applied to release top 100 Lists. However, rankings given to some of the celebrities raise the doubts on the credibility of those media. Even then, it must be remembered that if any celebrity gets least place or no place in the list, fans should not suspect the credibility of the Lists. Instead, they should try to understand why that celebrity gets least importance in that list.
