Correlations that are used to assess reliability typically result in lower values than those used to assess validity.

Question

Reliability and validity are assessed using different criteria and methods. Correlations used to assess reliability (e.g., test-retest reliability, internal consistency) often result in high values when a measure is consistent. Validity correlations (e.g., criterion validity, construct validity) assess how well a test measures what it claims to measure, and these can vary widely in value depending on the strength of the relationship between the test and the criterion or construct. There is no inherent reason why reliability correlations should be lower than validity correlations.
