1. Double-blind

   A blind or blinded experiment is a test or experiment in which information about the test that might lead to bias in the results is concealed from the tester, the subject, or both until after the test. Bias may be intentional or unconscious. If both tester and subject are blinded, the trial is a double-blind trial. For example, when asking consumers to compare the tastes of different brands of a product, the identities of the product should be concealed – otherwise consumers will generally tend to prefer the brand they are familiar with. Similarly, when evaluating the effectiveness of a medical drug, both the patients and the doctors who administer the drug may be kept in the dark about the dosage being applied in each case, to forestall any placebo or nocebo effect, observer bias, or conscious deception. Blinding can be imposed on researchers, technicians, subjects, funders, or any combination of them. The opposite of a blind trial is an open trial. Blind experiments are an important tool of the scientific method, in many fields of research—medicine, psychology and the social sciences, natural sciences such as physics and biology, applied sciences such as market research, and many others. In some disciplines, such as drug testing, blind experiments are considered essential. In other disciplines, blind experiments would be very useful, but they are totally impractical or unethical. An oft-cited example is in the field of developmental psychology. Although it would be scientifically expedient to raise children under arbitrary experimental conditions, such as on a remote island with a fabricated enculturation, it is obviously a violation of ethics and human rights.
