having knowledge, talent and being competent is a double edged sword

if a human knows much, is talented and/or is competent, 

then the human's social group expects that the human keeps knowledge secret, hides talent and conceals being competent to outsiders and only shows knowledge, talent and competence among humans which are considered trusted in social group 

if humans don't follow these unspoken expectations, they are not considered trustworthy, who are they really loyal to and so on, 

so they are usually murdered by humans in their own social group or from other social group

this is a reason human politicians tries to lower their own value by trying to seem uninformed, talentless and incompetent in public 

and this is also why actors and singers tries to lower their own value by getting into personal drama in public 

and this is why countries are very comfortable using violence to protect what they consider to be their deniable operator
