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