OB is still developing as a scientific discipline. While it draws from other fields like psychology, its ability to precisely predict human and organizational behavior is more limited compared to fields like physics or mathematics that deal with less complex and variable subjects. OB would likely be on the lower end of the scale, perhaps a 5 or 6, recognizing both the progress it has made as well as the challenges of its subject matter. Continued research can help strengthen OB's scientific foundation over time.
