Controlled Remote Viewing was developed in the laboratory, and continues to be studied and researched today. In research mode, the researcher is in charge of the session. No frontloading or any other information can be given, in order to keep the research pure and non-polluted. Because the very presence of a monitor always adds at least some pollution to a session, a session done in research mode will often not have a monitor, or anyone else in the room. If a monitor or anyone else is present, the session is always performed "double blind", and most often, the monitor is not allowed to say anything other than the coordinates and the start and end times. The monitor is never allowed to interact physically with the viewer and/or his/her transcript during the session.
