So which is it? Is the poll a fact or nearly a fact?


I've already said. Please keep up. The poll is a fact. They are 100%
correct about the fact they represent. They are reasonably (and more
importantly, usefully) close to 100% correct about the facts that they ask
about.

If you're having trouble distinguishing between the two, I recommend you
find a decent statistics book.

Exactly what is "useful" about exit polls taken on election day?
Exactly what is useful about other political polls for that matter,
unless you are a democratic who can't think on his/her own and needs a
poll to tell them what to do. :-)

Democrats and Republicans will both heavily use the exit polls. In a couple
of months, a book about the size of a dictionary will come out with all the
exit poll data. Both sides will use the info to figure out why people voted
the way they did, and how they can use it to their advantage in the future.
Exit polls are very accurate when used properly.

One use of exit polls is to check the accuracy of the election. As a
pilot, you probably appreciate the value of redundant systems. The
exit poll data can give you an indication of a problem in the
electoral polling process.

If the election result and the polling data radically disagree, it is
probably worthwhile to look closely at both the election and the exit
poll to figure out the source of error...

I disagree with this. Exit polls are not taken by every person that
votes. I don't participate in them for instance. They only exist so
that the media has something to report throughout the day instead of
just reminding everyone when the polls close and watching the clock in
anticipation. I for one believe the media should keeps its mouth shut
and not even talk about the election other than reminding everyone it is
election day until states are finalized.

I'm confused -- what are you disagreeing with? Are you arguing that
any source of inaccuracy (no matter how small) in the polls
invalidates their usefulness as an indicator? Why?

If you can estimate or measure the potential error from people
refusing to participate then you can adjust your error bounds on the
polling data.

For example, lets say that the exit polls at my local firehouse showed
that 90% of folks voted for Joe the garbageman, and only 10% voted for
Bob the fireman for our new position of block captain. If the
election results showed that Bob the fireman won by a landslide, I
would want to know why! It may be a problem in the polls, but perhaps
something fishy was going on at the firehouse... Are you arguing that
when it looks like there may be a problem it is better to look the
other way?

They only exist so that the media has something to report throughout
the day instead of just reminding everyone when the polls close and
watching the clock in anticipation. I for one believe the media

other than reminding everyone it is election day until states are

I strongly agree that the media should not report any election results
(from polls or otherwise) until the election is complete. It is not
fair to the candidates if their reporting influences people's voting
decision.

and there is the problem - can you really estimate or bound the error
from all the error sources (e.g., people not participating or
deliberately lying to the poll)?

Yes.

You cannot "bound" the error in an absolute sense, except to say that it's no bigger than the total population, which is useless. However, if a poll is done right, you can estimate the likely error. For example, "95% of the time, the error will be
less than 1%. 98% of the time, the error will be less than 5%" (I'm making these numbers up since they depend on how well the poll is conducted, and how big the sample size is, etc). This is where the standard deviation of the mean comes in as an
estimate of how good your measurement is.

Of course it cannot be used as a "backup" to voting. However, it can (and should) be used as a screening to indicate whether this particular situation warrents closer investigation. IF the actual voting disagrees with the exit poll by enough
(depending on how the poll is conducted), then there is a good chance (though not a certanty) that there is funny business going on somewhere. It could be that the poll is incorrectly reflecting the actual intended (by the voters) results. However,
it could also be that the election incorrectly reports the voters' choices.

I absolutely believe in redundant systems, but only if each system is
itself reliable. Exit polls simply aren't reliable enough for me to
consider them a redundant system.

The poll is not a fact. It is potentially a close approximation of a fact.


They are 100%
correct about the fact they represent.


They are almost never correct about the fact they are trying to represent.
