MIT’s culture is made up of our collective values and beliefs. This means we have the power to shape that culture into one that is more diverse, equitable, and inclusive — but we must all do our part. This July, after years of stagnation, the MIT administration promised again to do its part by hiring a senior officer for diversity at each of its five schools and the new College of Computing. But given the sheer difficulty of addressing each department's unique culture, school-level officers are not enough: Every department deserves diversity.
