Question

Quizplus · Accepted Answer

The double-blind procedure is best for testing for placebo effects because it involves both the researchers and participants being unaware of who is receiving the placebo and who is receiving the actual treatment. This eliminates the possibility of the researchers unintentionally influencing the results or the participants responding to the researchers' expectations. This design allows for a more accurate assessment of the true effects of the treatment versus the placebo.
