I would say that some systems are not designed to be discriminatory against a group, but since the designer blind spot for the problem might still play a part. Systems designed to be "neutral" has to be evaluated against a ideal neutral. If we find discrepancies then the system is fixed until it's as close to neutral as possible.

By ideal neutral is that their outcome aren't that disparate considering the supposed goal of the system: access to X resource, ability to accomplish X, etc.
