Brain substrates explain differences in the adoption and degree of financial digitalization.

This study analyzes neural responses connected to trust and risk to explain financial digitalization decisions. It shows that brain responses distinctively inform differences in the adoption of digital financial channels that are not shown by any other sociodemographic or behavioral indicators. From a methodological standpoint, the study explores if usage patterns of digital financial channels and instruments are associated with psychological and biological indicators; it uses functional magnetic resonance imaging (fMRI) to investigate whether financial digitalization decisions are linked to the evoked brain response to the safety associated with video images of financial transactions through digitalized and non-digitalized channels; it conducts trust and risk neuro-experiments to identify their impact on financial digitalization decisions and it analyzes whether brain structure is linked to financial digitalization behavior.
