In other words, those very characteristics which are demanded by war — the ability to tolerate uncertainty, spontaneity of thought and action, having a mind open to the receipt of novel, and perhaps threatening, information — are the antitheses of those possessed by people attracted to the controls, and orderliness, of militarism. Here is the germ of a terrible paradox. Those very people who, because they have adopted attack rather than submission or flight as their preferred psychological defence against threat, are in theory the best suited to warring behaviour, may be the very ones least well equipped for other components of successful fighting.
