A difficulty facing those who plan and review behavioral studies is the risk of harm of the subject. They believe that it can affect negatively on the physical and emotional aspect of the subject.
However, in behavioral and social science, physical and emotional harm is unlikely. The only purpose of experiments is to observe people's behavior. Most of the time, subjects do not know that they are part of an experiment because if they do know about it, they will probably change their behavior. They will only be informed as soon as the experiment is over. The results of social experiments and research will become insignificant and unreliable if subjects are aware beforehand.
During 1803, Napoleon Bonaparte, who was the French ruler at that time, controlled the Louisiana Territory. President Jefferson believed that the French leader may be a threat to American trade and travel, so he decided to negotiate the Louisiana purchase. By doing so, the US would be able to use the Mississippi River and the Port of New Orleans more freely; both ports had been used by farmers to ship their crops and get paid. Jefferson was able to buy the Louisiana territory from France, since Napoleon Bonaparte needed money for the Great French War. As a result, with the purchase of this new territory, the land area of America nearly doubled.
