In the context of psychological testing, what would a lack of standardization lead to?

A lack of standardization in psychological testing can lead to inconsistent results and misinterpretation because standardization provides a framework to ensure that tests are administered, scored, and interpreted in a consistent manner across different settings and populations. When tests are not standardized, variations in how they are given or interpreted can result in unreliable data. This inconsistency can impede the ability to accurately compare results across individuals or groups and may lead to erroneous conclusions about a person's psychological state or needs.

Standardized tests are designed to have uniform procedures and norms, which help ensure that the results are valid and can be generalized to a broader population. Without this consistency, the risk of misinterpretation increases, making it difficult for practitioners to understand the true meaning behind a person's test scores. Furthermore, inconsistently administered tests may fail to take into account cultural, socioeconomic, or contextual factors that could affect the outcome, further complicating the interpretation process.
