The evolutionary reason some of us have agency and most of us do not, is because reason is subject to temporal failure, and information is subject to intertemporal failure, and instinct provides a very successful method of graceful failure.
Meanwhile selection for success of those with agency allows others to adopt new knowledge and understanding by imitation without abandoning their dependence upon intuition.
This is the same reason we still have cheaters. While cooperation is most beneficial under ordinary circumstances, cheating (immorality), and predation (violence), are extremely valuable methods of graceful failure.
The animal majority is insurance in case we fail. But they are not to be taken seriously whatsoever.
