A system includes a biometric sensor configured to detect physiological data associated with anxiety of a user, a memory, and at least one hardware processor executing operations. The operations include selecting a plurality of stimuli from a pool of stimuli, the selected plurality of stimuli including at least one target stimuli associated with a subject matter and at least one generic stimuli not directly associated with the subject matter. The operations also include presenting each stimulus to the user, collecting sensor readings from the biometric sensor, and generating anxiety results. The operations also include determining an anxiety score based on the anxiety results, identifying a plurality of risk tolerance ranges, each risk tolerance range being associated with a category of risk tolerance, and determining a risk tolerance result of the user based on comparing the anxiety score to the plurality of risk tolerance ranges.
