Stanford's rate is 4.3x higher than that.
Add in that half of all students who claim a disability have no record of a diagnosis or disability classification prior to beginning college, all the reports of rampant cheating in school, the Varsity Blues college-admissions scandal where some parents helped their kid fake disabilities to get ahead, and even people here who seem to think it's ok to defraud the system to get ahead?
I think perhaps elite schools need a better way to gauge an applicant's ethics to deny them entry since the last thing the world needs is more unethical people in positions of power.
You are perhaps mistaking which side of the line Stanford would select for. It is a school that produces and prefers sociopaths. Its engineering curriculum, almost uniquely among universities, has no requirement for an ethics course. You can fulfill Stanford's "Technology in Society" requirement by taking a course where you network with VCs for a semester. It is a factory for making jerks.
