Question

Case-control designs have a high degree of internal validity because they eliminate the problem of recall bias.​

Quizplus · Accepted Answer

Case-control designs are actually prone to recall bias, as the cases may remember their exposure history differently than the controls. This can lead to inaccurate estimates of the association between the exposure and the outcome. However, case-control designs may still have high internal validity if other sources of bias are minimized and the study is well-designed and executed.
