It's amazing to me how people latch on to a concept like the "Alpha Male" (which was recanted by the very person who coined the phrase in the first place), or "Nine phases of Grief" (also recanted by its inventor), or "Multitasking" which has been disproved by neuroscience. We actually "switch task" because our brains can only focus on one thing at a time. These errant concepts persist for years, even decades after they've been rejected. For example, if you apply for a job, at many companies, they still ask you to take the Myers/Briggs Personality Test, which is a completely unscientific series of mumbo-jumbo questions that supposedly give the employer insight into your personality. It's based on Carl Jung's typology principles of sensation, intuition, thinking and feeling. Jung has repeatedly disapproved of the Myers/Briggs interpretation of his principles, which, in and of themselves, are shaky.
