"biases in computer systems can be difficult to identify let alone remedy because of the way the technology engages and extenuates them. Computer systems, for instance, are compar- atively inexpensive to disseminate, and thus, once developed, a biased system has the potential for widespread impact. If the system becomes a standard in the field, the bias becomes pervasive. If the system is complex, and most are, biases can remain hidden in the code, difficult to pinpoint or explicate, and not necessarily disclosed to users or their clients. Further- more, unlike in our dealings with biased individuals with whom a potential victim can negotiate, biased systems offer no equivalent means for appeal."
