Final answer:
Mike Rugnetta describes Victorian science as 'restrictive' due to the simultaneous advancement in genuine scientific fields and the emergence of pseudo-scientific claims that violated scientific principles.
Step-by-step explanation:
According to Mike Rugnetta, the host of Crash Course Mythology, Victorian science was often characterized as being restrictive. During the Victorian era, while science made incredible advances, especially in the fields of medicine and biology, there was also a notable growth in scholarship under the guise of science that did not adhere to the principles of the scientific method. This created branches of pseudo-science, which, in essence, refers to theories or practices that are presented as scientific but lack empirical support, are untestable, or have been disproven - labeling them as 'false science'.
