Fuller comments how ironic it is that, at his time, 3 billion $ was appropriated by the United States Government for higher education, where the most probable self-improvement is 0%. On that basis he believed that the educational system needed soon to be reformed on a completely different strategy, to deal with facts such as these presented by Dr.Bloom .
Dr.Bloom goes on to explain that from birth to four years there are clearly three defined factors which govern the inauguraton of capability to improve IQ. Factor number one is trust. Human young stay helpless longer than any other living species. If the new life has it's utter trust in its parents violated then it is pretty sure to be a dropout. The next two factors are autonomy and initiative, which more or less go together. You do not know how to tell the young life to stand up-it just stands by itself when ready. The initiative is innate.
