This collection includes all notes that deal with pseudoscientific claims, which were often the foundation of medical and scientific debates during the Progressive Era. Many of the texts here support or challenge turn-of-the-century scientific racism. 

Evolutionary psychology was another feature of pseudoscience that enabled scientific sexism by promoting biological essentialism. Silas Weir Mitchell and George Miller Beard are two prominent physicians from the period that used theories of evolutionary psychology to justify arguments about female "neurasthenia."
