In a particular math PhD application, there are multiple questions along the lines of "please describe personal experiences and perspectives and what you would bring to our community", as well as a place to attach unspecified "supplemental documents". It appears that these areas of the application are not specific to the math department but rather are shown to all applicants to the university's graduate school.
Honestly, I don't think I have anything to add in these areas, having written about my experiences already in my statement of purpose. I was not expecting to have to provide so much personal (i.e., not research-related) information in the PhD application.
Would it negatively impact my application to leave these areas blank? Should I say "see statement of purpose"?
Background: this is a top 10 pure math PhD program in the USA.
