Abstract

Psychometric testing objectively measures individual differences in cognition, personality, and behavior. Current advancements
focus on improving test validity and reliability via statistical modeling, bias reduction, and digital adaptation for enhanced acces
sibility. Artificial intelligence integration promises personalized assessments and deeper psychological insights. The validation of
translated instruments, like the Malay FNES-R and Czech BFI-2, is crucial for cross-cultural research. The Big Five Inventory’s
utility in predicting social and economic outcomes is also a key area of study, highlighting the practical application of psychometric
tools.
