Lee's Oracularities: How to Raise the Intelligence of the Average Person?

The Internet Oracle has pondered your question deeply.
Your question was:

> O great and nifty Oracle, is there some way to raise the intelligence
> of the average person without going through that nasty business of
> slaughtering the dumber ones?

And in response, thus spake the Oracle:

} Firstly, hand out Brown hair dye to all 'dumb' blondes. This IQ-in-a-bottle
} will add at least 10 points to them overnight.
}
} However, the only problem with your mission is that an IQ of 100 is the
} national average. That means that even if you were to kill off all the dumb
} people you would actually LOWER the IQ of the intelligent people. The IQ of
} 100 would be adjusted to fit the new average intelligence. Those outstanding
} individuals with IQs of 140+ would now not be so outstanding, comparatively
} speaking.
