I think it might depend on what ability or trait you are measuring.
e.g. if it was intelligence, the platykurtic group would have more at
the top and bottom IQ level and a wider spread at a lower middle IQ
level.
So with more geniuses available, this group might outdo the mesokurtic
(normal) group.
If the group ability is not dependent on having more top performers,
but rather a greater number of better mid-level performers, then the normal
distribution group might be the best.
