Document Summary

Measure iq, again 5 years later, again 5 years later and graph it ideal, but are long and people drop out. Get 1000 iq measurements now and graph it. Result: iq starts high (age 15), then drops. Deemed to be false, due only to the testing method. Can"t compare fifteen year old with forty year old. Longitudinal graph showed much less drop, mostly flat line. Not good because it compares apples to oranges , not following same people over time. John horn 1980 (2 types of intelligence) 2 intelligence types: fluid and crystallized intelligence. Use to acquire new language, learn new things. Ability to apply previous learning to new situations. Real iq remains fairly stable because it is composed of both types. No known level of lead considered safe=big problem today. Vitamin a, d in large doses (cleft palate) 1960"s-new birth defect-missing arms, legs in babies. Due to thalidomide: originally a sleeping medication, also used for morning sickness.
