self-fullfilling prophecies

the book mentions them in the intelligence chapter. the book talks about how tracking aptitude tests and always measure intelligences and things of that sort create a self-fulfilling prophecy. Basically if you track a student or ignore or tell the kid something (or things of all that sort) will lead the child to be 'smarter' (what the tracking of aptitude tests would do) or make them 'dumber' (ignoring or telling them they can't do it)

Self-fulfilling prophecies are kind of funny because of how true they are and how often they happen. For example in coaching student-athletes if the coach never puts the kid in or bashes them at practice instead of encouraging them the student will (almost always) develop into a 'cripple' at that sport and not try and then become worse. this could then lead into problems with other things in the child's life. An example of my own life: working this summer I always complained to my coworker about how i was crazy and that 'this place' (taco bell) was driving me out of my skull. and he always said 'hey man if you think it, it will happen' he always told me 'your a walking self-full filling prophecy.' eventually that happened. I worked days and nights at taco bell. I had no sleep schedule. my sleep was erratic and short. soon I was becoming delirious (even more than i already am haha) and I actually had hallucinations at certain points during some work night. they were mostly audible hallucinations but I was hearing things that weren't there or happening. I told my boss and he laughed he explained to me that taco bell and working days and nights kills the brain. He told me that I would return to normal when school came around and i stopped working nights and days simultaneously. I then told my coworker that i was losing my mind and he explained to me that fluorescent lights block the production of melatonin in the brain and because of the hindered ability that your brain goes through due to the lights you won't be able to sleep.

that is merely one example of those self-fulfilling prophecies. what are some of yours?
one way that a self-fulfilling prophecy in my life that relates to our book is that my mother, yes i am talking about her again and frankly i have every right to. she raised me very well in comparison to a lot of people these days and she is a wonderful and very intelligent person. so deal with me talking about her. I have to listen to all of your s**t all day but i digress. She always encouraged my mental development and pushed me to do my work and all of that and never let me accept giving up
