1. Heritability of intelligence will increase as the environment becomes more favorable towards its development.

2. Herrnstein believes that once social and legal barriers are removed, social mobility will be determined (and pretty much stopped) by biological determinants, thus defeating the explicit aims of "all modern political credos."

3. The increase of social wealth (another aim of all current political philosophies, according to Herrnstein) will widen the gap between the upper classes and the lower classes since the upper class will tend to draw those from the lower class with more native endowment.

4. Technological dislocation of labor is going to create a chronically unemployed, technologically unemployable group of workers who do not have the minimum I.Q. to get new jobs in an increasingly complex society.

5. Since those with the high I.Q.'s in society will tend to mate, the other factors beside I.Q. which influence success will also gain a higher heritability.

In an interview last week, Herrnstein defended his article as a "realistic" appraisal of what was happening in society today. When questioned about the reliability of the I.Q. test, Herrnstein said that the present I.Q. test was reliable for many reasons. He cited not only the predictive power of the test but also its validity in society.

"The best thing about this test is its translability and exportability Because it relies on bits of arbitrary, specific information, it's not culturebound. Historically, the test could go from France to Belgium to Portugal to England. Because of this, the child is being measured, effectively, with all of Western society, his own peer group."

He said that his use of Jensen's statistics was entirely non-controversial. "All Jensen did was to collect the figures of four standard identical twin studies from the 1920's. All I have done is use his conclusions based upon the data."

Herrnstein noted that his use of the statistics was different from Jensen's. Whereas Jensen was trying to determine the nature of the differences in biracial I.Q., Hernnstein was interested in the role I.Q. played in social standing.

He did, however, characterize as "a bunch of baloney" the contention that it would be impossible to determine whether differences in racial I.Q. were due to inheritance or environment.

Then I first wrote the article, I thought that it would be hard. But now I think that all you would have to do is take the areas of the test in which the identical twins differ and see if the crucial black-white differences show up in those areas."

As far as his predictions, Herrnstein believes that they are dismal "only in the light of our political heritage." In the short run, he said he "wanted people to realize that their political goals are fighting the nature of the beast."

"America should not be handling important matters of social policy on the basis of imaginary facts," according to Herrnistein. Asked to what he referred specifically, Herrnstein mentioned a recent Supreme Court decision which barred an employer from giving intelligence tests to janitors on the ground that such a job did not involve the use of intelligence and such a test was used discriminatorily against blacks.

"I doubt that such a thing is true. It's been my experience that every job requires a certain amount of intelligence. What I object to is not Congress's right to legislate equality of opportunity but equally of outcome," he added.
