Nonetheless, phrenologists still exist today. Several scientists have used MRI studies as a way of refuting the practice using modern scientific methods. Parker Jones, Alfaro-Almagro, and Jbabdi (2018), for example, used structural MRI to quantify local scalp curvature. The scientists found that there was no correlation between phrenological claims and the actual structure of the skull. Implications of Gall’s phrenology on modern neuroscience Anonymous (1860).

The mind was located in one of 26 distinct regions, or “organs”” with connective white matter in between. Followers of Gall would go on to add additional regions. Believing that an individual’s faculties could be modified over the course of a lifetime, Spurzheim modified the strict deterministic view of people and introduced the potential for treatment and change. These traits, however, were still heritable (Morin, 2014). Applications Phrenology in 19th century Britain Though phrenology had plenty of doubters — and was sometimes horrifyingly used to promote white supremacy — this medical craze did actually touch on some truths about how brains work.

Alexander Maconochie, who, for a short time, was the progressive governor of the Norfolk Island penal colony, was deeply influenced by the discipline.

Differences in the physical and behavioral characteristics of peoples have been noted since antiquity. Records from ancient Greek, Roman, Egyptian, Hebrew, Chinese, and other civilizations remarked upon the distinctions among the languages, customs, and appearance of peoples. However, it was not until the rise of European exploration, conquest, and colonialism that something like the modern concept of “race” begin to take hold. This idea stipulated innate, inherited, unchanging differences, behavioral as well as physical, in human groups. 1 One of the first Europeans to classify humans based on race was the French physician and traveler François Bernier (1620-1688). In 1684, Bernier classified humans into distinct races based on geography. 2 Bernier’s classification was typical of those that followed through the 18 th century, which were based on observations and reports from travelers, missionaries, and colonial officials. These reports often supplied highly ethnocentric descriptions of skin color, temperament, and other features which were used to classify human races. Some of these authors spoke from the authority of their own experience in Africa, Asia, or the Americas, as did Bernier. Other authors relied on their scholarly expertise as naturalists, as did, for example, the Swedish taxonomist Carolus Linnaeus (1707-1788). 3 All of these early racial classifications were largely the product of written field reports and observations until the late 18 th century and the rise of comparative anatomy.An illustration and definition of ‘phrenology’ from Webster’s Dictionary circa 1900.

During the early 20th century, a revival of interest in phrenology occurred, partly because of studies of evolution, criminology and anthropology (as pursued by Cesare Lombroso). The most famous British phrenologist of the 20th century was the London psychiatrist Bernard Hollander (1864–1934). His main works, The Mental Function of the Brain (1901) and Scientific Phrenology (1902), are an appraisal of Gall's teachings. Hollander introduced a quantitative approach to the phrenological diagnosis, defining a method for measuring the skull, and comparing the measurements with statistical averages.

In the second-last article in our series Biology and Blame, James Bradley details some interesting facts about this pseudo-science. 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. [34] Phrenologists had never been able to agree on the most basic mental organ numbers, going from 27 to over 40, [41] [42] and had difficulty locating the mental organs. Phrenologists relied on cranioscopic readings of the skull to find organ locations. [43] Jean Pierre Flourens' experiments on the brains of pigeons indicated that the loss of parts of the brain either caused no loss of function, or the loss of a completely different function than what had been attributed to it by phrenology. Flourens' experiment, while not perfect, seemed to indicate that Gall's supposed organs were imaginary. [37] [44] Scientists had also become disillusioned with phrenology since its exploitation with the middle and working classes by entrepreneurs. The popularization had resulted in the simplification of phrenology and mixing in it of principles of physiognomy, which had from the start been rejected by Gall as an indicator of personality. [45] Phrenology from its inception was tainted by accusations of promoting materialism and atheism, and being destructive of morality. These were all factors that led to the downfall of phrenology. [43] [46] Recent studies, using modern day technology like Magnetic Resonance Imaging have further disproven phrenology claims. [47] Finger, Stanley (2004).
