Summary / Abstract: 

Beyond financial indicators, alternative indicators have been shown to predict financial behaviour (e.g., loan repayment). However, as these alternative indicators include factors such as mental health, physical health, parental attachment, relationship stability, and social capital (e.g., centrality in online social network), there are issues of sensitivity and transparency. In a simulated credit card application, perceived question sensitivity correlated negatively with disclosure. In one condition, text-based justifications were provided for each items, although this had no impact on disclosure, suggesting people may generate and rely on internal models of legitimacy. Privacy fundamentalists (Westin scale) were least likely to disclose.
