Impact factor is impact of journal, though its an outcome of the articles published in that journal, but precisely it is the contribution of all the articles published in that journal within two years, not individual articles. For individual articles, citations and quality of the content should be more important, and shall be the only parameter to be used for its evaluation. We can correlate it with the reputation of any school or college. We can rank the school or college at any scale, but when it come to recruit someone for any particular job, it is that individual who need to provide sufficient credentials. Though, candidates from premier organizations are always preferred, but its not that recruiter can blindly pick any candidate from that premier organization. So the crunch to put this example, is actually to ask why we depends on the impact factor, and don't prefer to read articles in non-impact journals.
