Practical and Cultured?

[vartan]

Cultured is the first step in the Cultured-Erudite-Scholastic-Pedantic line of traits. Erudite is the best, but after it, you get pure penalties. Which should not be that way, as it makes no sense for an Erudite to have +1 management and a scholastic or pedantic person to lose that in favour of influence and hitpoint penalties.

Naturally the Q arises: why? Why then do the scholastic and pedantic lose the management in favour of the influence and hitpoint penalties?
