If we're going to put this kind of stock in cultural perceptions we should consider also the converse: the long-standing association of disorderliness with inspiration, creativity, and genius.
I think we can both agree genius is the exception to the rule, not all geniuses are disorderly and rather geniuses can function highly or even thrive in environments where people of average ability can not, but in no way does disorderliness create geniuses.
OK, exclude genius from my statement. Let just limit it to creativity and inspiration. Messy business.
Of course, my real point is that both connections are tenuous and reductive. It's a fun bit of pop psychology, but I doubt either is actually true in general.
