know, we Americans are a
statistics-happy bunch.
There’s hardly
anything we talk about or write about that doesn’t have at
least one statistic as an integral part of it — sports, politics,
economics, and so on.
Which is OK, I
suppose. After all, what harm can statistics do? They’re just
numbers.
Well, they can do plenty of
harm, when they’re used to give an appearance of solidity
to something that is nothing more than pure wind.
(By the way, that
beautiful phrase about solidity and wind is George Orwell’s
creation, not mine. I wish it were.)
Anyway, let me give
you an example.
Following is a
paragraph taken from an article that appeared in the July
31, 1995, edition of the San Francisco
Chronicle.
"The typical black
student with combined Scholastic Aptitude Test scores
between 701 and 850 had a 56% likelihood of graduating from a
college where the average student’s score was 900. But his or her
likelihood of graduating fell to 39% at a more selective school,
where the average student’s score was 1000."
Now just what did the
paragraph say that was useful? In my opinion, nothing. And
yet the writer of the article built an entire thesis supporting
so-called affirmative action around it and other similar paragraphs.
The statistics
themselves, assuming they were properly and honestly
gathered, were objective and unbiased. The thesis based upon an
interpretation of those same statistics was not.
Nor could it be, for
the simple reason that while a measurement can be neutral, an
opinion, inference, or judgment about the meaning of that
measurement cannot.
Think about it.
