From studies of baboon clans, this steroid level-
(a) is generally low in high ranking males and high in low ranking males. They are high for high-ranking males when the societal hierarchy is under threat.
(b) is high when the personal threat is unpredictable and arbitrary.
(c) is higher when a baboon is unable to distinguish a real threat from a non-threat.
(d) is lower where baboons have a social outlet for anger.
(e) is lower when they are sociable and not alone.
