How may a scientific argument change over time?

A scientific argument may change over time due to the emergence of new evidence or findings that challenge previous conclusions. This process is fundamental to the scientific method, emphasizing the importance of replication and peer review in validating research. When results from an experiment or study cannot be consistently replicated, it raises questions about the validity of the original argument. Additionally, biases in research can affect outcomes and interpretations, leading to adjustments in the argument as further data and scrutiny reveal more accurate insights. The dynamic nature of scientific inquiry means that as new information comes to light, previous arguments may need reevaluation or modification to better align with current understanding.

In contrast, other options suggest static views of scientific arguments or imply that change is due to invalidation or consensus, which does not capture the evolving and self-correcting nature of science.
