What drives one to trust strangers? We find generalization mechanisms underpin decisions to trust. Strangers resembling past individuals previously known to be trustworthy or untrustworthy are trusted more, or less, respectively. These behavioral gradients were mirrored neurally: patterns of amygdala activity were elicited in a graded fashion when perceiving increasingly untrustworthy strangers.
