The second issue to consider is whether the costs of both kinds of errors are symmetric. In the case of symmetric costs, the trade-off between the two kinds of errors is of less concern. However, when the costs are asymmetric, the trade-off in the system must be considered. Illegal immigration is a minuscule problem nationwide and the concern of terrorist conduits is an issue in a handful of border districts. However, false negatives—that is, mistakenly excluding an Indian from the NRC—has an extremely high human cost because of the severe penalties. False negatives could tear families apart, and force the poor, who tend to lack documents, to spend their resources on legal appeals against detention, or spend years at detention centres. So, trading Type I errors for Type II errors is a very bad bargain for Indians.
