The results reveal that different subjects prefer distinguishable regions of the face-space, highlighting the essential subjectivity of the phenomenon. The different sculpted facial vectors exhibit strong correlations among pairs of facial distances, characterizing the underlying universality and complexity of the cognitive processes, leading to the observed subjectivity.
