The US spends billions on foreign aid. But it doesn’t know how much good our money is doing.

“Over the past two decades, researchers have become much better at determining whether a certain idea actually achieves intended goals. The focus on results — evaluating whether a program benefits people cost-effectively — has changed philanthropy and even the US government’s domestic programs.

In theory, USAID recognizes the importance of making sure their programs work. But in practice, it’s largely failing to do so.

Two USAID reviews, one by USAID’s office of the inspector general in 2019 and another commissioned by the agency in 2020, reveal two dismal facts: The agency gives out billions to programs that don’t achieve their intended expectations, and, worse, it’s not even sure of the impact of most of the money it gives in aid. Recent agency moves and statements suggest that USAID wants to fix this problem. Whether it can will determine the fate of billions of dollars — and the health and well-being of many millions around the world.”
