I agree with Steve, this is unlikely. The two-year age groupings a matter of convenience, and like all things done established by FIDE, subject to alien influence.
(I notice that the sidereal year of Mars is about 687 Earth solar days - almost two of our years. Maybe this is a clue to the origin of Kirsan's aliens.)
Ken has it right, encouragement, positive reinforcement, and recognition. Of course, we have to have some sort of divisions, which are inherently unfair. Even with 1-year groupings, there will be significant differences in age. However, I am not the only person who thinks that requiring 10-year olds to compete in the same division as 11-year olds is a little unfair. Hence, the junior trophies.
