Subjects in experimental research are randomly given to either the control or treatment group. A double blind study has group assignments of every subject from the participant and the researcher experimenting.
If the former is informed of which group they’re assigned, there’s a potential risk of their behavioural change, which will influence the results. On the other hand, if the latter knows which group the former has been assigned, their actions might disclose the task or directly affect the results.
A double blind study protects against such risks, guaranteeing that any significant or insignificant difference between different groups can be assigned to any of the treatments.
Blinding refers to the withholding group assigned to each participant. Studies can be single binding study (occurs in different study kinds), double binding study or triple blinding study (used mainly in medical research).
The blinding ensures the internal validity of a study or makes you confident enough that any argument, finding or discussion on your flu vaccine will not change the result.
It is unlike a non-blinded study, as in the latter, participants can modify their behaviour or researchers find non-existent effects. Blinding, thus is important and helps avoid biases in scientific research.
Unblinding happens when researchers blind experimenters or participants but still they gain information on which treatment (fake or real vaccine as in the case of flu vaccine study) is given to them before the completion of an experiment. Thus, unblinding results in indistinguishable outcomes. A suitable paradigm of unblinding:
You’re studying the influence of a recently developed instruction program in your school to better students’ comprehension skills.
You arbitrarily assign this new program to a few students while other students are guided with the standard program. You utilize a single blinding study: you don’t inform students which one out of the two instruction programs they are receiving to keep their behaviour constant. Students in a standard program might put more effort into their reading ability to prepare themselves and for not enrolling in the newly introduced program, or put less effort as they may believe that other students will excel at a much faster rate as compared to them.
Thus, the outcomes can be fallacious unless if you don’t unblind.
Blinding refers to hiding from the control group and the treatment group about what treatment has been assigned to them to gain accurate research results.
Blinding studies are of three types – single, double, and triple binding study. In the former only participants are unaware of the treatment group and control group assigned to them. In the next, both experimenters and participants are unaware. In the last, participants, experimenters, and researchers are unaware.
A double blind study is a study in which experimenters and participants are uninformed of the treatment and control group.
