Classical experiments tend to be better at controlling threats to internal validity than addressing external validity.

Question

Quizplus · Accepted Answer

Classical experiments are designed to tightly control the experimental environment in order to eliminate potential confounds and threats to internal validity. However, this often comes at the expense of addressing factors that might impact external validity, such as the generalizability of results to real-world situations and populations. This does not mean that classical experiments are irrelevant for addressing external validity, but they may require supplementary measures to help establish the generalizability of findings.
