What must historical sciences rely on due to certain limitations?

Historical sciences, which study past events and processes such as evolution, geology, and ancient climates, often must rely on multiple competing hypotheses to draw conclusions. This approach is important because historical sciences deal with unique events that cannot be replicated or directly observed.

By generating several hypotheses, researchers can explore different explanations for the same set of evidence. This diversity of thought is crucial in historical sciences because it encourages thorough investigation and discussion, leading to a more robust understanding of complex phenomena. Competing hypotheses can be tested against available evidence, allowing scientists to evaluate which best fits the data while remaining open to new findings or interpretations.

In contrast, relying solely on proven theories, a single hypothesis, or empirical data alone could limit the scope of inquiry and understanding in historical sciences. These methods might not adequately capture the complexity and multifaceted nature of historical events and processes, where evidence can often lead to multiple interpretations or viewpoints.
