The investigative judgment doctrine has been criticized, in part or whole, by a few vocal Adventists since the late nineteenth century, such as D. M. Canright, A. F. Ballenger, W. W. Fletcher, W. W. Prescott, Louis R. Conradi, and Raymond Cottrell. Many of these individuals ultimately left the Adventist church. Issues with the traditional Adventist interpretation of Daniel 8:14 were acknowledged by a number of North American theologians in the 1950s, with the result that a special committee was formed to discuss "problems in the book of Daniel".
