I believe that's a distinction without a difference. Most scientists have a hard enough time understanding statistical significance in well controlled experiments and they are (ostensibly) trained for it. There's so much noise in business data that it's like reading tea leaves, except no one can prove it because by the time they gather enough data they realize that the management and/or market dynamics have introduced even more noise so everyone keeps chugging along, blissfully unaware that they're indulging in statistical fantasies and reinforcing whatever beliefs they already hold.
