<p>An FAQ from the Yale admissions website:</p>
<p>“I am not an artist or musician, and I have not engaged in any original research. Am I at a disadvantage for not submitting supplementary material? Should I submit something else?
Please do not feel any pressure to submit supplementary material. For the vast majority of our applicants, we evaluate the quality of extracurricular activities and talents through self-reported activity descriptions, essays, and comments made by recommenders. For a very small number of exceptionally talented artists, musicians, and researchers, we may find it useful to refer tapes/CDs, slides, and/or abstracts to the appropriate Yale academic department for evaluation. Unfortunately, we are unable to evaluate DVDs or video tapes, so please do not send them.”

<p>I think this makes it pretty clear the types of supplementary materials Yale will evaluate – tapes, CDs, slides, abstracts. Ordinary (or extraordinary!)research papers are NOT listed. Yale admissions has 20,000+ applications to review. I recommend that you showcase your writing skills by submitting great essays, OP.</p>
