Then there is this bit from Culture of Critique

Almost one-half of Kadushin’s (1974, 23) sample of elite post-World War II American intellectuals was Jewish. The sample was based on the most frequent contributors to leading intellectual journals, followed by interviews in which the intellectuals “voted” for another intellectual they considered most influential in their thinking. Over 40 percent of the Jews in the sample received six or more votes as being most influential, compared to only 15 percent of non-Jews (p. 32).

This quote especially I found interesting

By 1968 Walter Kerr could write, “what has happened since World War II is that the American sensibility has become part Jewish, perhaps as much Jewish as it is anything else… The literate American mind has come in some measure to think Jewishly. It has been taught to, and it was ready to. After the entertainers and novelists came the Jewish critics, politicians, theologians. Critics and politicians and theologians are by profession molders; they form ways of seeing.”
