Reconcile Willingness and Ability for Institutional foundation, question, general, ability, average

Iginla2010

On the 2002 endowment IPS question it says the foundation has:

average ability

above average willingness

"taking both ability and willingness into consideration, the endowment's risk tolerance is best characterized as above average"

I thought for institutions you would look primarily at ability. In general, don't you usually honor the more conservative of the 2?
