The Rosenhan experiment was a famous experiment into the validity of psychiatric diagnosis conducted by David Rosenhan in 1972. It was published in the journal Science under the title “On being sane in insane places.”

Rosenhan’s study consisted of two parts. The first involved the use of healthy associates or “pseudopatients,” who briefly simulated auditory hallucinations in an attempt to gain admission to 12 different psychiatric hospitals in five different states in various locations in the United States. The second involved asking staff at a psychiatric hospital to detect non-existent “fake” patients. In the first case hospital staff failed to detect a single pseudopatient, in the second the staff falsely detected large numbers of genuine patients as impostors. The study is considered an important and influential criticism of psychiatric diagnosis.

The War of Jenkins’ Ear was a conflict between Great Britain and Spain that lasted from 1739 to 1748. After 1742 it merged into the larger War of the Austrian Succession.

Under the 1729 Treaty of Seville, the British had agreed not to trade with the Spanish colonies. To verify the treaty, the Spanish were permitted to board British vessels in Spanish waters. After one such incident in 1731, Robert Jenkins, captain of the ship Rebecca, claimed that the Spanish coast guard had severed his ear. The British government, which was determined to continue its drive toward commercial and military domination of the Atlantic basin, used this incident as an excuse to wage war against Spain in the Caribbean. In 1738 Jenkins exhibited his pickled ear to the House of Commons, whipping up war fever against Spain. To much cheering, the British Prime Minister, Robert Walpole, reluctantly declared war on 23 October 1739.
