Why Are Self-Report and Behavioral Measures Weakly Correlated?
Open accessPublished version of a preprint
Abstract
Accumulating evidence indicates weak correlations between self-report and behavioral measures of the same construct. We suggest that these weak correlations result from the poor reliability of many behavioral measures and the distinct response processes involved in the two measurement types. We also describe how researchers can benefit from appropriate use of these measures.

Laboratory and neuropsychological measures of flexibility have high construct validity but do not always match real-world flexible behaviour reported by self- or informant-report questionnaires.
“laboratory-based measures and neuropsychological tests have high construct validity but may not always converge with real-world flexible behaviours as indexed using self-report or informant-report questionnaires, which typically have greater ecological validity21.”
From Cognitive and behavioural flexibility: Neural mechanisms and clinical considerations (2021) · cites this paper as [21]
Informant-report questionnaires typically have greater ecological validity, while laboratory-based measures can provide greater construct validity for assessing executive function and cognitive flexibility.
“EF ability and cognitive flexibility can be assessed using informant-report questionnaires, which typically have greater ecological validity, or laboratory-based measures, which can provide greater construct validity(5).”

Self-report and behavioral measures of the same construct are only weakly correlated, possibly because behavioral measures tap responses during highly structured situations and index maximal performance, whereas self-report assesses behavior across unstructured real-life situations.
“More generally, self-report and behavioral measures of the same construct are only weakly correlated, possibly due to the fact that behavioral measures tap responses during highly structured situations and typically index maximal performance, whereas self-report assesses how individuals behave across unstructured real-life situations (5).”
From Brain Mechanisms Supporting Flexible Cognition and Behavior in Adolescents With Autism Spectrum Disorder (2021) · cites this paper as [5]
Measures with high reliability such as informant or self-report may better predict individual differences in real-life outcomes, whereas behavioral measures sensitive to within-person experimental manipulations may be important for studying processes that underlie task performance.

“For example, the average correlation between self-report and behavioral measures of self-control [1,2], emotional intelligence [3], empathy [4], risk preference [5], and creativity [6] ranged from 0 to 0.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
