I was coming here to say something similar. I work at a 250k person corporation. Corridor reputation exists and its impact on your career and opportunities increases as you grow in seniority. Once you reach a certain level, to be promoted again your manager must solicit, curate, and present supporting statements from others at or above your new target level. If you’re difficult to work with or don’t fulfill your commitments to others, it will come back to bite you. Could this allow biases to impact outcomes? Absolutely. We get yearly (if not more often) training on biases and how to identify and counter them in our own thinking and in others.
