You may of heard your English teacher
mention to write a "blind essay." It's part of the lingo

See, a lot of writers-turned-literary-critics will cringe when you use the word I too much. Frequent use of it when not in a position paper (and even then in moderation) makes the entire written object sound sophmoric, and of lower diction. Most experts say that when writing an admissions essay, avoid using "I" too much, it could cost you between an acceptance and rejection letter to college.

Of course the term was coined by somebody witty and probably spent a lot of time grading essays.
