Brain Types - Commercialization and Criticism

Commercialization and Criticism

Educational society and members of American Psychological Association criticize Brain Types as not valid and built for commercial purposes only. Mr. Niednagel, a lay-scientist of 30 years, with a Bachelor’s degree in Business Finance from California State University, Long Beach, says his method is the most accurate (in applying the Jungian/Myers model) and verifiable. He believes that, when he has had the time, he has had 100% accuracy rate in assessing and localizing brain functioning on the basis of "eyeballing" and then analyzing body language, posture, motor activity, and speech. These claims, however, remain disputable. Current knowledge of the use of fMRIs, transcranial magnetic stimulation, and electroencephalography to monitor brain waves and brain function makes the idea of having the ability to look at someone and determine features of their brain far too simplistic.

Dr. Sandbek, primary contact of the Sacramento Skeptics Society, in his publication Brain Typing: The Pseudoscience of Cold Reading criticized the validity of Brain Types and claimed "how closely the Brain Typing of Jonathan P. Niednagel fits as a pseudoscience".
