Reinforcing and validating the values of goods are the social values of men.
How far may we trust our experience as validating the inferences we draw from it?
In the context of organizations and their use of assessments in the hiring process we are often referring to criterion-related validation.
Criterion-related validation is the empirical relationship between a predictor and a criterion. Validation will show an organization how well their selection system is able to predict future job performance.
In essence, the stronger the relationship between the assessment and performance the more likely your selection system will predict successful employees.
