showed that only IQ had predictive value when pitted against values theories.

How you control for values? If I value taking peoples money by force because I feel like it my intelligence will negate that values effect on my life outcome?

How you control for values?

The cultural values of the respondents are measured by their responses to a question on the values parents would most like in their children. The survey gives 13 values and asks respondents to identify the one that they would most like their children to have, and also the three they would most like their children to have.

These were the values surveyed:

  Success
  Studiousness
  Amicability
  Cleanliness
  Considerateness
  Control
  Honesty
  Interest
  Judgment
  Manners
  Obedience
  Responsibility
  Sex role

Table 1 gives the percentages of the respondents endorsing each of the 13 values they would most like their children to have, for the five religious categories. ... There are only two values in which Jews are significantly different from others. These are honesty, which Jews desire in their children less than others, and judgment, which Jews desire in their children more than others. ...

Table 2 gives similar results for values being one of the three most important that the respondents would most like their children to have. ... There are eight values in which Jews are significantly different from others. Jews attach less importance to cleanliness, honesty, manners and obedience, but they attach more importance to considerateness, interest in how and why things happen, judgment and responsibility. ...

the results do not provide any evidence for the theory that Jews attach more importance to success or to studiousness than non-Jews. In fact Jews attach less importance to success and to studiousness than non-Jews in the results set out in both Tables 1 and 2, although the differences between Jews and non-Jewish are not statistically significant. ...

Jews do attach more importance to four values than non-Jews. These are considerateness, interest in how and why things happen, judgment, and responsibility, but it is not easy to see how these would contribute to the success of Jews in virtually all walks of life.

This is not controlling for values taken as a given, as it is worded as most like. E.g., if my son excels in soccer there would be no desire on my part for increased aptitude in sports.
