There is a famous story where a Jew sees another Jew in a subway and he goes up to him asks him for the time. Jew #2 says another. Jew #1 repeats his request and Jew 2 again says nothing.
After much harassment by Jew 1, Jew 2 finally says, “I don’t want to tell you the time, because if I tell you the time, we’ll start shmoozing and eventually I’ll invite you to my home for Shabbos and then you’ll meet my daughter and I know you’ll want to marry her and I don’t want my daughter to marry a guy who doesn’t have a watch.”
The smarter you are, the better you are able to see the consequences of your actions and the more likely you are to be aloof. Whites are less aloof than asians but more aloof than blacks just as whites, on average, have lower IQs than asians but higher IQs than blacks. Blacks are more easy-going than whites who are in turn more easy going than asians. Blacks are more quick with a compliment than whites who are in turn more quick with a compliment than asians. Asians are more likely to be monogamous than whites who are in turn more likely to be monogamous than blacks. Asians are more likely to have a job than whites who are in turn more likely to have a job than blacks. Asians are more likely than whites to save money and to educate themselves and to preserve their family and to stay out of jail and to avoid STDs and stupid accidents.
