How much can environment alter intelligence? In one study, striking increases in IQ occurred in 25 children who were moved from an orphanage to more stimulating environments. The children, who were all considered mentally retarded and unadoptable, were moved to an institution where they received personal attention from adults. Later, these supposedly retarded children were adopted by parents who

gave them love, a family, and a stimulating home environment. The children gained an average of 29 IQ points. For one child, the increase was an amazing 58 points. A second group of initially less "retarded" children, who stayed in the orphanage, lost an average of 26 IQ points. Other encouraging results can be found in early childhood education programs, which provide stimulating intellectual experiences for disadvantaged children. In one study, children from low-income families were given enriched environments from early infancy through preschool. By age 2 their IQ scores were already higher than those in a control group. More important, they were still 5 points higher 7 years later. High-quality enrichment programs such as Head Start can prevent children from falling behind in school. A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years. These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them. It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society. Children moved from orphanages to stimulating environments

a. made major gains in IQ.
b. maintained the same IQ.
c. made slight gains in IQ.
d. lost IQ points.

All governments tax, penalize, punish, restrict, and regulate their people. Governments in the United States – the federal government in Washington, the 50 state governments, and the more than 86,000 local governments – take nearly 40 cents out of every dollar Americans earn. Each year, the congress enacts about 500 laws; federal bureaucracies publish about 19,000 rules and regulations; the

state legislatures enact about 25,000 laws; and cities, counties, school districts, and other local governments enact countless local ordinances. Each of these laws restricts our freedom in some way. Each dollar taken out of our wages or profits reduces our freedom to choose what to do with our money. a. There are many laws and regulations that attempt to govern our lives in ways that may sometimes penalize, punish, or regulate the people they should protect. b.
