Although slight results can and do happen for all age groups, my experience is that students will get them more often. Why? There are three primary reasons, the first two of which have to do with maturity and not knowing themselves as well as someone in their 30’s+.
First, a student could be reporting what they do or how they were trained by parents, teachers, or their culture, rather than who they are. Second, a student could be reporting what they wished they were, or what they think they should be. Students would be more likely to look up to the so-called popular crowd and answer according to what they perceive would make them a member of that group, or what would earn their parents/teachers approval.
