Failure May Bring Unexpected Success

That was Albert Hirschman's belief:

“We may be dealing here with a general principle of action,” Hirschman wrote:

Creativity always comes as a surprise to us; therefore we can never count on it and we dare not believe in it until it has happened. In other words, we would not consciously engage upon tasks whose success clearly requires that creativity be forthcoming. Hence, the only way in which we can bring our creative resources fully into play is by misjudging the nature of the task, by presenting it to ourselves as more routine, simple, undemanding of genuine creativity than it will turn out to be.

And from there Hirschman’s analysis took flight. People don’t seek out challenges, he went on. They are “apt to take on and plunge into new tasks because of the erroneously presumed absence of a challenge—because the task looks easier and more manageable than it will turn out to be.” This was the Hiding Hand principle—a play on Adam Smith’s Invisible Hand. The entrepreneur takes risks but does not see himself as a risk-taker, because he operates under the useful delusion that what he’s attempting is not risky. Then, trapped in mid-mountain, people discover the truth—and, because it is too late to turn back, they’re forced to finish the job. “We have ended up here with an economic argument strikingly paralleling Christianity’s oft expressed preference for the repentant sinner over the righteous man who never strays from the path,” Hirschman wrote in this essay from 1967. Success grew from failure:

And essentially the same idea, even though formulated, as one might expect, in a vastly different spirit, is found in Nietzsche’s famous maxim, “That which does not destroy me, makes me stronger.” This sentence admirably epitomizes several of the histories of economic development projects in recent decades.

 In ways, I agree with him.  We just can't plan for what might happen.  However, that really irks the practical, scientific part of me.  But the realistic part of me knows that actual events tend to run in direct contrast to the amount of planning put into them.  I highly recommend the article.
