Psychohistory/secret

The general information in the library data entry is not entirely correct. The reason large-scale psychohistory experiments are no longer conducted is due to the unpredictable results achieved by the only sizable experiment to date, which was conducted as a part of the Psionics Suppressions. The unforeseen results of this experiment were so far-reaching that Imperial scientists concluded that their knowledge of the principles involved was woefully inadequate and that further study was required. Imperial research into psychohistory is undertaken at a small number of research stations and is carried out under the strictest of controls.
