Trust operates through unspoken inferences rather than explicit articulations. [causal]
The way in which symbolic controls operate, moreover, tends characteristically to be unquestioned and indeterminate. It proceeds for the most part by inferences which remain uncommunicated and which therefore do not even need to be defined or properly justified. This is why a very precise articulation of reasons and views is not in keeping with either the demonstration of trust or the withdrawal of trust. Even for those who seek trust, it is not required; it can quite easily even become a disrupting factor or, even more, may arouse distrust. It would contradict the function and style of trust to request and offer detailed factual information and specialized arguments, although the possibility of such an explanation ought to be hinted at.
