Many commonly used measures of identity salience, defined as the propensity to situationally invoke an identity, ask survey respondents what they would say about themselves in a hypothetical situation. These measures assume that the information we would most likely volunteer to a new acquaintance reflects our most salient identities. But how well do these measures—what we say that we would say about ourselves—truly reflect the individual? These commonly used measures that conceptualize identity salience as talk within a hypothetical situation may result in poor conceptual fit, suggesting that their reassessment is warranted. We assess the operationalization of identity salience using data that include objective measures of speech and behavior. Speech is coded from unobtrusive snapshot audio recordings made during the respondent’s daily life. Behavior is measured using ecological momentary assessment, recording daily life activities in 3-hour intervals. We predict both salience measures using identity commitments for three common identities: friend, parent, and religious. For each, we estimate and compare the strength of their associations to answer the question driving this research: is telling others about an identity equivalent to behavior in the identity, and to what extent does each of these fit into the identity model?
