Science Experiments
Science experiments are a central method for advancing human intellectual inquiry and developing tools and methods for improving the quality of life for people. As a basic foundation of the knowledge humans enjoy of their world and themselves, all of the information gained through a scientific experiment can be of great value, but it also holds the danger of being misleading and time-wasting if the basis by which the data is collected is flawed in its approach. An important method for guaranteeing the validity of the results of scientific experiments is known as the double-blind, which is intended to control the information about a scientific experiment available to both the researchers and their subjects. Ideally the distorting effects of bias can thus be shielded from scientific experiment results.
A basic aspect of controlled scientific experiments consists of the existence of two separate groups of research subject. Closely resembling each other in most respect, the groups differ in that one is treated as the experimental sample for the scientific experiment and the other as the control sample. They are distinguished from each other in terms of the independent variable in question, with the experimental group being subjected to the substance or process being tested by the scientific experiment and the control group going without it, perhaps, in the case of a drug trial, to receive a placebo. This basic structuring of the subjects in scientific experiments thus aims to put results in context. It still does not entirely eliminate problems of interpretation raised by the inherent nature of scientific experiments as designed and artificial experiences usually constructed with an eye toward producing a particular result.
In a scientific experiment run according to the double-blind method, both the researchers and subjects involved in the process remain unaware of the make-up of the control and experimental groups. This information is only revealed to them after the data gathered in the scientific experiment has been gathered. In some scientific experiments the research data is even submitted to analysis before the researchers learn about the two sample group. The double-blind technique often appears in scientific experiments conducted to test the efficacy of pharmaceutical products. Since pills can be easily made to resemble each other in appearance and taste, it is relatively easy to ensure that the double-blind remains intact and shields the accuracy of the scientific experiment. This technique has proved more difficult to realize in fields where treatments are more conspicuous and difficult to mask than pharmaceutical products. A scientific experiment on the effectiveness of a variety of surgery, for instance, may experience difficulties creating a control group of non-effective. Despite the value of the double-blind method in reaching conclusions for scientific experiments potentially bringing wide-reaching benefits, they may also raise ethical issues in cases where its implementation implies the denial of helpful treatment to patients who need it. A scientific experiment that draws on this method can thus be held up to a higher standard of accuracy than less rigorous testings but also carries its own set of problematic issues.
