Giffen Data?

Thanks, Bill. It looks to me on the Archive as though it's all there, but for some reason there were no carriage returns. Perhaps this message has the same flaw.

Mike,

Somehow your email came through with the message clipped. Take a look at
how it looks on the CSGnet archive.

I'm also not sure that one's imagined place in the income

distribution has much to

do with the "interests" that determine how one votes. I think that,

as long as

things aren't going too badly for too many people, people probably

just vote for

the candidate who seems to be most like oneself in intelligence and
self-righteousness;-)

The best explanation I've heard.

It could also be that they are correct. People who listen to NPR may be
more highly educated than average, plus other factors which combine to
put them in higher income categories. So if NPR listeners tend toward the
high end of various distributions, it could be true that they all
are in the top 1/5 of the income category, relative to the general
population. The sample is skewed.

This may indeed account for what was reported, they only way to know
would be to replicate the study by controlling for the subjects actual
income level. It was my understanding that Those presenting the report had
interviewed people as a part of voter exit polling. Voters are themselves
a schewed self-selected group. However, if it turns out that half of the
population actuall does think they are in the top 1/5 or 1/10 of the income
distribution then we'd have an explaination for why economic measures that
are of benefit to so few have the support of voters.

Or, maybe in line with, or similiar to something Rick suggested, people may
think that those who have high incomes are so admirable that they ought to
have even higher incomes.

Oh, not NPR listeners. That makes a difference. Voters are more likely, I
would think, to be representative of a broad range of income. Anyone need
an old used theory?

Remember the Time proclamation "Dewey beats Truman!"

It was a well conducted poll with one minor exception. It was a telephone poll and in 1948 most people did not have telephones. Only the 'well to do' could afford them. Coincidentally, the 'well to do' tend to be Republican. Thus the poll was skewed.

I don't recall the source of this threads poll. But before we charge off trying to explain it we should verify it's accuracy.

I don't think it's a delusion, really. It's just ignorance.

It can't be "just ignorance." Something is going on which results in
people misreporting their standing in the income distribution. It's like
the kids on the Prarie HOme Companion who are "all above average." But, it
is something that wouldn't be all that difficult to replicate. Or, who
knows maybe I was delusional when I only thought I heard it on NPR.

For the record, the notorious telephone poll was conducted by _Literary Digest_ for the 1936 election, not the 1948, as Steve said, or 1932, as Bill Williams said.

Which notorious telephone poll. Certainly not the Dewer-Truman poll. To
which one are you referring?

The _Literary Digest_ telephone poll in 1936, which predicted a landslide by Alf Landon (because Republicans owned most of the phones then), has become a textbook example of how not to conduct a survey. Willams and O'Shaughnessy were correct in remembering the nature of the problem, just wrong about the year; and O'Shaughnessy had asked about the source.
