Which Experimental Scenario Would Likely Produce the Most Trustworthy Results

Question

Which experimental scenario would likely produce the most trustworthy results?
A) a double-blind study involving a new heart disease treatment
B) an unbiased investigation that shows a strong correlation between two variables
C) a single-blind experiment testing the effects of caffeine on blood pressure
D) an experiment that is slightly biased but does not use a model organism

Accepted Answer

A double-blind study involves both the researcher and participants being unaware of who is receiving the treatment and who is receiving the placebo. This reduces bias and increases the reliability of the results. In addition, a new heart disease treatment is likely to be a significant health concern, making it essential to have trustworthy results before it is widely used.
