<p>According to ARWU ranking methodology, the following statement seems reasonable: “Arts and humanities are not ranked because of the technical difficulties in finding internationally comparable indicators with reliable data. Psychology/Psychiatry is not included in the ranking because of its multi-disciplinary characteristics” [ARWU</a> FIELD Ranking Methodology 2009](<a href=“http://www.arwu.org/ARWUFieldMethodology2009.jsp]ARWU”>http://www.arwu.org/ARWUFieldMethodology2009.jsp)</p>
<p>Benchmarking needs verifiable facts; interpretation is even harder. </p>
<p>Back to US News rating, IMHO, USNWR ranking can be better improved if they provide the means for users to select the weight (importance) of various factors, which could provide more meaningful (weighted average) results from the user perspective.</p>
