Seems like it applies to economics as well:
"Physicists spend a large part of their lives in a state of confusion.
It's an occupational hazard. To excel in physics is to embrace doubt
while walking the winding road to clarity. The tantalizing discomfort
of perplexity is what inspires otherwise ordinary men and women to
extraordinary feats of ingenuity and creativity; nothing quite focuses
the mind like dissonant details awaiting harmonious resolution. But en
route to explanation -- during their search for new frameworks to
address outstanding questions -- theorists must tread with considered
step through the jungle of bewilderment, guided mostly by hunches,
inklings, clues, and calculations. And as the majority of researchers
have a tendency to cover their tracks, discoveries often bear little
evidence of the arduous terrain that's been covered. But don't lose
sight of the fact that nothing comes easily. Nature does not give up
her secrets lightly." -- Brian Greene The Fabric of the Cosmos,
Chapter 16.
