When subjects are given two drinks but not told what they are drinking in order to get accurate results on which is the better tasting one-this is an example of what type of experimental design?

Blind.

Explanation:

In a blind experiment, information that can affect the participant's decision after the experiment is not told or we can say blinded until the experiment is over. Good blinding can eliminate experimental biases. A blind can be imposed on any participant. So in the question we conclude that it is blind experimental design.
