Within friendships, importance is placed on the ability to discern the level of affection for real friendships opposed to instrumentality for fake friendships.
By contrast, technical rationality governs "systems" of instrumentality, like industries, or on a larger scale, the capitalist economy or the democratic political government.
The dichotomy of instrumentality v. affection can not be ignored within friendships, as affection may be offered in order to receive instrumental aid from friends.
