Pseudoscience is not considered a true form of science primarily because "Pseudoscience does not have testable hypotheses or observable evidence."
True science relies on the scientific method, which involves creating hypotheses that can be tested and observed through experiments and empirical evidence. Pseudoscience often lacks this framework, making claims that cannot be rigorously tested or validated. Therefore, it does not adhere to the principles of scientific inquiry and fails to provide reliable, reproducible results.
The other options listed do not accurately capture why pseudoscience is not considered true science. While pseudoscience may change or may focus on certain topics, these characteristics alone do not define its scientific validity. Similarly, having measurable data does not mean the data is scientifically valid if it is not derived from a rigorous methodology.
