We observed that the first reform was not required until the Industrial Revolution.

The scientific approach depends on the detailed explanation of the subject of investigation. This careful thinking may also require some definition and observation when looking for relevant attributes of interest; observations often require careful classification, measurement, and / or count. A system that carefully collects relevant quantities and mass measurements and counts and classifies differences is the main difference between fake science (such as alchemy) and science (such as chemistry). Scientific measurements are typically tabulated, drawn or plotted and statistically manipulated, such as correlations and regression. Measurements can be made in controlled environments such as laboratories, or objects that are somewhat difficult or inoperable to access like populations.

In biology, the concept of "manipulation" is very important for the definition of experimental (and observed) science. Experimental science is about how manipulation affects measurements and clinical trials are about how intervention affects health or biomedical related results. Historically, there is little confusion about these differences, but the "incident" announced by the National Institutes of Health seems to avoid this historical understanding, rather than "intervention" and "health outcome" It seems to show a wide reading of. This greatly expanded the scope of clinical trials. In a way different from the original purpose of NIH. This contradiction and the resulting unintended consequences caused fear of trust.
