And your evidence is what? A proper study would require at least the following: 1) Take 40 random adults, give them a 5 year paid vacation with a job guarantee after the experiment. 2) Give each of those adults a nanny who is available 14 hours a day and is thrilled to repeat words 50 times any time you ask. 3) Give the adults a teacher who praises them profusely just for being able to repeat a goddamn alphabet after 4 weeks or longer. This is obvious to anyone who is not dependent on the academic industrial complex. But go ahead trying to impress people with "studies". Hint: Go through all papers published in the 20th century and see what percentage is relevant, especially in sociology and behavioral psychology. Most papers are useless.
