In the presence of non-compliance, the ATE can no longer be recovered. Instead, what is recovered is the average treatment effect for a certain subpopulation known as the compliers, which is the LATE. When there may exist heterogeneous treatment effects across groups, the LATE is unlikely to be equivalent to the ATE.

Treatment is very effective but worse than control: 0.2: 0.1: −10: Ten receive the treatment, and ten receive a control. Eight improve with the treatment and two do not. In the control group, nine improve and one does not. Therefore, the treatment was less helpful than the control in one of ten cases. NNT is 1/(0.1 – 0.2), which is -10.
