Fritz Fischer was a German historian who focused on WWI. He argued that Germany was completely responsible for WWI.
Fischer’s arguments were in almost complete contrast to those of earlier German historians who placed a significant amount of blame on the other major powers involved in the war. There was definitely a massive change in shared knowledge between the work of earlier historians and later when Fischer published his work.
The “our” in this Prescribed Title is important. Fischer’s work was very controversial within Germany and caused a tremendous amount of upheaval within the German academic community because it directly contradicted earlier work. Changes in shared knowledge can affect different groups in different ways. Not everyone’s confidence is affected in the same way. A TOK essay on this PT and RLE could split the “our” into different groups and compare and contrast the how confidence is affected.
