blindtests
A blind test, also written as blindtests in some usages, is an experimental design in which information that could bias results is concealed from participants, researchers, or both. The goal is to prevent expectations from influencing outcomes, measurements, or reporting. Blinding can apply to the identity of samples, the conditions of testing, or the treatment recipients.
Blinding types include single-blind, where participants are unaware of the sample identity or treatment; double-blind, where
Common methods include random assignment of samples, coded labeling (for example, sample A, B, C), and the
Applications span scientific research and consumer testing. In clinical trials and sensory evaluation, blinding reduces expectancy
Limitations include the risk of unblinding if information leaks, or if distinctive sample characteristics reveal identities.
