In the secular worlds of engineering and social structures, faith is needed when testing a new prototype construction or when giving a system a chance to prove its effectiveness. An aircraft or space shuttle doesn't fly until it flies, and a test pilot requires a generalized type of faith in believing that it will. A legal or economic system can only survive if sufficient individuals and groups have a faith in its usefulness and actively support its requirements. Faith then is the expectation that an untried construction or organization will adequately realize its intended purpose. If it fails or falls far short of its primary objective, then a persistent faith is a particularly useless method of attempting to correct for the deficiencies. Having an unshakable faith in a bridge that collapses, or an spacecraft that disintegrates, is a perversity of no pragmatic merit.
In the emotional world of politics and interpersonal relations, an individual can entertain a hopeful expectation that another person or group will attain some desirable objective. In the arena of war for instance, a population may have faith that a military leader or group can achieve a much sought victory, without having much trust as to what they will do subsequently. Even the most cynical of hardened pragmatists are obliged to have a species of faith more often than they might readily admit to.

In religious systems on the other hand, because there is never any verification of the beliefs of faith, the faith itself is included as part of the system. Professing to have faith by believing in the unverified claims of the system is the condition which the system claims will assure salvation..whatever that means. If one has faith in a mindless belief, and part of the system is the phenomenon of having a blind faith, then clearly the very act of believing is all that is needed to sustain and justify the system. Such circular self-serving nonsense is the enduring source of the intergenerational transmission of psychiatric cultural disorders. The astonishing fact remains however, that such remarkable bombastic claptrap has the ability to induce an individual to accept the certainty of such a belief structure, whilst negotiating the unlimited chaos of contrary evidence. The perpetuated belief that a next life will adjust and reward the inequities of the present, is the means by which various authorities induce the general population to accept their lot, and perform acts which just happen to be politically and economically beneficial to the authority itself. By ingesting substantial amounts of ecclesiastical hope and dwelling upon the fantastical appeal of after-death package deals, the individual can ignore the realities of life's contingencies and inhabit a virtual world of anticipation.
