All the following are strengths of randomized experimental designs in impact evaluations EXCEPT which of the following?
A) Time order is correctly specified.
B) Causal mechanisms are easily identified.
C) The influence of other variables is ruled out.
D) Internal validity is generally high.

Question

Quizplus · Accepted Answer

Randomized experimental designs are highly effective at establishing causality and controlling for external variables, thus ensuring high internal validity. However, they do not inherently make it easier to identify the causal mechanisms behind the observed effects. Identifying causal mechanisms often requires additional qualitative or quantitative analysis beyond the experimental design itself.
