Admissions Officers are on the clock. To get through thousands of applications, AO’s must read about 5 applications an hour, meaning they have 12 minutes to read your file. That includes looking over your course rigor, transcript, GPA, test scores, reading your high school’s profile, teacher recommendations, essays, guidance’s Secondary School Report (SSR) and interview report. And then they have to make notes – all within 12 minutes.
The MORE you send them, the more they must SKIM your file – reading the first and last paragraph of your essay and teacher recommendations. The more an AO skims your file, the LESS likely they are going to capture the essence of who you are. Many students don’t understand that even one additional recommendation makes an Admissions Officer start to skim. That’s why Yale has this warning on their applications page, along with this video: http://admissions.yale.edu/advice-putting-together-your-application#supplementary
Admissions Officer DO NOT have the time, or expertise to read an applicant’s research paper – published or not. The most you should send them is a one-paragraph (100 words) abstract of your paper: https://writing.wisc.edu/Handbook/presentations_abstracts_examples.html
Remember, LESS is always MORE. Do not send the research paper, as sending it will adversely effect the outcome of your application.
