Phrenology was mostly discredited as a scientific theory by the 1840s. This was due only in part to a growing amount of evidence against phrenology. Phrenologists had never been able to agree on the most basic mental organ numbers, going from 27 to over 40, and had difficulty locating the mental organs.
When was phrenology dismissed?
Even in 1815, the year that Spurzheim published his influential book on Gall's method, phrenology was dismissed by one reviewer as “a piece of thorough quackery from beginning to end” (Gordon, 1815).
Why is phrenology no longer used?
Despite its initial popularity, phrenology started losing support from scientists in the 20th century due to methodological criticisms and failure to replicate various findings.
