When an algorithm denies someone benefits or flags them as a risk, it's often unclear who is responsible for reviewing or correcting that decision. This accountability gap grows as governments rely more heavily on automated systems.

When a country can't repay its debts, negotiations with lenders happen case by case with no consistent rules, often favoring lenders over the country's ability to recover. This can trap nations in cycles of debt renegotiation that stall development for years.
