What process ensures that experimental results can be trusted over time?

Repetition is a critical aspect of the scientific method that strengthens the reliability and validity of experimental results. When an experiment is repeated multiple times, it allows scientists to verify that the outcomes are consistent and not due to random chance or specific, isolated circumstances. Through repetition, researchers can identify patterns, confirm findings, and increase confidence in the data collected. This process also aids in detecting any anomalies or errors in the methodology, which can be corrected in future trials. Consequently, experiments that yield consistent results across multiple repetitions are deemed more trustworthy, which is essential for scientific integrity and advancement.

While observation, hypothesis testing, and peer review are vital components of the scientific process, they do not specifically address the long-term reliability of experimental results in the same manner that repetition does. Observation provides initial data, hypothesis testing evaluates predictions based on theories, and peer review ensures that research meets certain standards before publication, but it is repetition that firmly establishes trust in experimental findings over time.
