In the short story Internal two men belive they are to conduct a study on their bosses brother and return to their boss when the study is finished to provide their results. When they end up at the apartment it is abandoned except for the two sent to observe the brother, so they begin to observe each other. What i belive happened is the two men were being used as human lab rats and the entire time were most likely being observed by their bosses who were making there own conclusions about the observers. Staying in a rundown apartment with little food and nobody else around to observe a person you know nothing about and not questioning it at all makes no sense to me, and that is probably what the bosses were interested in studying,what would cause a person to put themselves through something like that. It would obviously be a pshycological problem which we are told the doctors are main feild of study is.
