Regression-discontinuity designs employ a quasi-experimental approach, but they attempt to replicate the features of randomized trials by introducing randomness around the cutoff point. This makes the inferences drawn from a well-implemented regression-discontinuity design comparable in internal validity to randomized experiments. However, the method also assumes that the functional form of the relationship of the outcome with the running variable is known with certainty, which is a critical assumption in the design, and sensitivity tests should be conducted to assess the robustness of the findings.
