Question

Quizplus · Accepted Answer

The main problem with J.B. Rhine's Zener card studies was the lack of replication. The initial studies produced curious findings, but the results were not consistently reproduced in subsequent experiments. This lack of replication makes it difficult to draw definitive conclusions about the validity of the results. The other options, such as lack of prior hypothesis, lack of peer review, and falsifiability, may have been issues as well, but none of them were the main problem with the Zener card studies.
