During an experiment, what type of study is conducted when neither the subjects nor the researchers know who is receiving the treatment versus the placebo?

Prospective
Randomized controlled
Double-blind
Single-blind

The correct answer is: Double-blind

The described scenario refers to a double-blind study, which is a key type of clinical trial design aimed at minimizing bias. In a double-blind study, neither the participants (subjects) nor the researchers who interact with them know which individuals are receiving the treatment or the placebo. This design is critical because it reduces the risk of biases that could affect the outcomes of the study, such as the placebo effect or the researchers unintentionally influencing the results based on their knowledge of who is receiving treatment. This method ensures that the results are more reliable and valid, as it helps keep the assessment of the treatment's effectiveness free from subjective influences. In terms of research integrity, the double-blind approach is highly regarded in clinical trials for its ability to maintain objectivity and support the credibility of the findings.
