Talk about profiling... this is longitudinal profiling.
Profiling is right on the mark. Can you imagine a study that would have access to individuals from early childhood to adulthood, just so you could compare sociological traits such as "whininess" and their eventual political leaning? Quite frankly, I'm not even sure it could be done with any sort of confidence. Where do they even track such data on students in a way that could be easily retrieved and compared? What happens after the child becomes an adult--how do these researchers inquire about their political side?
I'm raising the BS flag!
