These results are more widely accepted in conducting further research. All these things will lead to some amount of bias in the experiment which will not reflect the true purpose of the test.įor a company who is looking at concrete results, researchers use double blind experiment to remove both experimental and participational bias. This may further lead to things like giving test subjects further clues or adding more coffee to the drink just to make it stronger. Now, if the individual who is moderating the test is also the employee of the company then there might be some conflict of interest as he/she would want his/her brand to score more and win the test. Past research shows that people act differently when they are moderated or belong to a specific group.įor example, if a company wants to conduct a taste test experiment in which participants compare two popular coffee brands to figure out if their brand is stronger or not. For the purposes of this discussion, a double-blind trial is defined as a study in which research subjects, the investigators, and the outcome assessors are. These experiments are an important part of conducting research for a company to know more about the product they want to conduct their research on. Double-blind studies are considered the gold standard in research because they help to control for experimental biases arising from the subjects’ expectations and experimenter biases that emerge when the researchers unknowingly influence how the subjects respond or how the data is collected. Here the subjects of the experiment or the persons who are conducting the experiment are not aware of who is in the control group.ĭescription: Double blind testing is a scientific approach where the company plans to eliminate the experimental bias of the test subjects and the researchers. Definition: A double blind experiment is a procedure undertaken by a company to gather important data about its products.
