IQ not just an ability, but also a dispositionThus explaining why intelligence isn't always behavior-optimizing.
Although general intelligence is usually conceptualized as differences in cognitive ability, IQ is not just about ability but also has personality implications .
For example, in some populations there is a positive correlation between IQ and the personality trait of Openness to experience (‘Openness’)  and ; a positive correlation with ‘enlightened’ or progressive values of a broadly socialist and libertarian type ; and a negative correlation with religiousness .
So, the greater cognitive ability of higher IQ is also accompanied by a somewhat distinctive high IQ personality type. My suggested explanation for this association is that an increasing level of IQ brings with it an increased tendency to use general intelligence in problem-solving; i.e. to over-ride those instinctive and spontaneous forms of evolved behaviour which could be termed common sense.
The over-use of abstract reasoning may be most obvious in the social domain, where normal humans are richly equipped with evolved psychological mechanisms both for here-and-now interactions (e.g. rapidly reading emotions from facial expression, gesture and posture, and speech intonation) and for ‘strategic’ modelling of social interactions to understand predict and manipulate the behaviour of others . Social strategies deploy inferred knowledge about the dispositions, motivations and intentions of others. When the most intelligent people over-ride the social intelligence systems and apply generic, abstract and systematic reasoning of the kind which is enhanced among higher IQ people, they are ignoring an ‘expert system’ in favour of a non-expert system.

IQ is more than ability
It is also a disposition, as Bruce Charlton explains:
