We can do more with already existing tricks

Research output: Contribution to journalComment/debate

Abstract / Description of output

To increase predictive accuracy at no extra cost, life outcomes including job performance can be predicted from individual questionnaire items in addition to even instead of composite trait scores. Items can be conceived of as markers of persome (the universe of behavioral, affective, cognitive and motivational differences among people), like single nucleotide polymorphisms (SNPs) are markers of genomic variance. Ideally, comprehensive items pools are used to capture persomic variance, but items of existing questionnaires can also provide incremental predictive accuracy. Item-level associations may reveal that outcomes are highly polycausal.
