Why are Double-Blind Experiments Used

Question

Why are double-blind experiments used?
A) The results will be more biased.
B) The results will be more controlled.
C) The results will be more objective.
D) The results will be more statistically significant.

Accepted Answer

Double-blind experiments are used to make the results more objective by eliminating any potential biases that could be introduced by the experimenter or the study participants. Neither the participants nor the researcher know which participants are in the treatment group or the control group, which helps ensure that their beliefs and expectations about the treatment do not influence the results. This helps to increase the validity and reliability of the results.
