examined and testified as follows:
EXAMINATION BY MR. WULF:
Q Would you state your name, please?
A John F. Kraft.
Q And your business address?
A 527 Madison Avenue, New York City.
Q Would you state your occupation, please?
A I am the president of an opinion and market research
firm.
Q Would you state your educational background,
please?
A I have a BA from Yale University and I did graduate
work at Columbia University for one year.
Q When did you get your undergratuate degree?
A In 1949.
Q IIow long have you been in the polling pro
fession?
A Fifteen and one-half years.
Q Would you relate your professional history?
A My first six years in this business were spent
with Elmo Roper 5 Associates.
The next three years were as a partner in Louis

Harris § Associates.
And for the last six and one-half years, I have
headed up my own firm.
Q Would you describe the nature of the work in
which you have engaged during your being employed in this
profession?
A It falls into two broad categories, one cf them
being political research, which is that which is heard
about most often.
The other and larger area is confidential consumer
research for clients in the business area.
In the six and one-half years we have been in
business, we have, for example, conducted a number of
research projects for the Union Carbide Chemicals
Company, a number of studies for the Union Carbide Con
sumer Products Company, several projects for the Corning
Glass Works, a number of studies for the Ford Motor
Company, and through N. W. Ayer, studies for such
clients of theirs as Armour, Johnson § Johnson, Illinois
Bell; for BBD § 0, a study for Air France; for Geyer,
Morey 5 Ballard, some studies for Rambler, and also for
many others.
Q Would you say for whom you have worked in
your political polling work?

A The political research we are doing now is, of
course, confidential.
But I can say that in the past, we have conducted
political research for such senators as Carl Hayden,
George Symington, George Smathers, William Fulbright,
Ross Bass, Lee Metcalf, Quentin Burdick, and others.
Q Could you describe generally the purpose of
one or two of the polls or sample projects that you have
undertaken?
A Commercial or political?
Q One or two of each.
A All of our work has required our getting representa
tive cross sections of the people with whom a client
might be concerned.
For example, for Ford, we have sought representative
cross sections of purchasers of new Ford automobiles.
For Corning Glass, we have had to select
representative cross sections of housewives.
And in many media studies we have had to select
representative cross sections of subscribers to particular
magazines.
In the political area, any study we undertake must
be based on the proper selection of a cross section of
the voting population, whether it be a study in Wyoming

or Georgia or New York City.
Q Can you briefly describe the method by which
you undertake a poll, whether it's for a political or
commercial client? I am interested in the techniques
involved in obtaining the information necessary for
the particular poll involved.
Q If we were doing a study among subscribers
to a magazine, we would request listings of subscribers
on a county by county basis throughout the United
States or on a state by state basis, depending on the
need, and select every one-hundredth, every tenth, or
even every one - thousandth subscriber for interviewing
purposes.
There are other ways to approach a random selection
of subscribers, but this should suggest a very basic
approach.
In a political survey, we would allot clusters of
interviews within a state on a random basis proportionate
to the description of the population within that state.
To clarify, we could decide that 100 interviewing
points at which ten interviews were to be done -- at
each of which ten interviews were to be done, that is --
would produce an accurate cross section of the entire
voting population.

We would then allocate those interviewing points
of ten interviews each to counties within a state at
random and porportionate to the size of those counties.
Now, if more than one point were to fall within
a larger county, we would then allocate these points at
random, proportionate to the size of population within
the county.
At a given interviewing point, we would specify
to an interviewer that he or she must begin at a given
point -- that is, a given point which had previously
been randomly selected -- and he would be directed
to begin at the third household at the northeast corner,
for instance, interviewing at every fifth household
around the block or down the street or all along the
rural route -- whichever was relevant to the local
situation.
Q What is the degree of accuracy with respect
to the entire population with which you are concerned
of the information which you obtain through investigation
of randomly selected cross sections of the population?
A The accuracy can vary, depending upon how intensively
you sample a particular population or universe. That
is to say, a national cross section of 2000 interviews
on such a question as, "Would you vote for Johnson

or Goldwater?" could be expected to produce an accurate
prediction, so to speak, within 2 or 3 per cent.
This has been the kind of experience that Gallup
has demonstrated during the last several presidential
elections.
A more intensive sample, that is to say, sampling
of one out of every ten people rather than one out of
every ten million people, will, of course, be much
more accurate.
There is, however, another factor to be considered
and that is that if a preference, as in the Goldwater-
Johnson illustration, is close to fifty-fifty, then
the accuracy would be less great than it would be if a
preference were ninety to ten, say.
However, there is no magic in doubling, tripling or
quintupling the sample size in the sense that accuracy
does not increase in direct proportion to the increase
in sample size.
I should add that to talk about percentage accuracies
I am doing this only very generally because accuracy
is based on the size of the universe or population being
considered and the intensity with which it is sampled,
and also the complexity of that population or universe.

Mr. Kraft, have you been satisfied that the results of
random sampling techniques are, in fact, very accurately
reflective of the particular kind of information which
you may be seeking in a particular poll?
A Not only are we satisfied but we have found, in hun
dreds of studies, that the sampling techniques I have
been describing here are really the only way to do a
proper job of producing the kind of cross section that
is needed in one situation or another.
Q I take it that, given these scientific random
sampling techniques, it is possible to investigate any
particular cross section of the population which would be
relevant to the study you are conducting?
A Yes.
Q What is the adaptability of the random sampling
technique to a different variety of problems presented
to you by anyone who might employ you?
To be more specific, if anybody wants to know
anything about a particular product or a particular
opinion in which they are interested, are you able to
provide this information to them accurately through the
random sampling technique?
A Yes. All that is required is knowledge of what
the population requirements are for that particular

product.
As I noted earlier, it may be housewives, it may
be people who smoke Philip Morris, it may be eligible
voters in the State of Washington, it may be beer drinkers
in New York City.
But once you understand the population you are
dealing with, then you can, and we have -- our colleagues
and competitors in this business have -- demonstrated
time and again the reliability of proper random sampling
of cross sections of the population on a scientific
basis.
Q Then you can provide any information of any
sort, just so long as it has to do with human behavior?
A That is right. Some are more difficult than
others.
Q To take a bizarre example, if you, sir,
wanted to know, for instance, how many people who owned
green cats would be interested in buying a narticular
brand of cat food, would you be able to establish
something of that sort?
A Assuming that there were green cats to be found,
proper random sampling methods could determine not only
how many green cats there were but also the preferences
for particular cat food as this affected the green cats

0 £0 you would describe, then, the random sampling
technique as a precise and scientific method for obtain
ing information of a great variety of sorts?
A It's indeed precise, within some of the limits I
have suggested -- the one or 2 or 3 per cent error
and it'sscientific because it removes the human element
from deciding whom to interview or what the universe may
be. It is impersonal.
Q If I put to you an example of this kind: Let
us assume there is a county in the State of Alabama
which has a population of approximately 15,000, which
consists of a Negro population of approximately 12,500
and a white population of 3000, and assume further that,
as in any representative community, there is not only
the description of population by race, but also by age,
education and economic status. And if I were to ask you
whether it would be possible to apply random sampling
techniques in order to obtain a very accurate cross
section of this particular community, in order to assure
that an accurate cross section of the community were
available for service on juries, would the techniques you
have described be applicable to this problem?
A There is no reason why they could not or would not
be .

0 Do you mean that there isn't any question
that it could be?
A I mean there is no question that it could be done.
Q In other words, the technique is trans
ferable to this particular situation?
A Not only that, but it would be easier than some
of the problems I have described to you earlier'.
Q Why do you say that?
A The information on the population of a county
in Alabama is much more complete in terms of sex, age,
economic level, race, average rental and other kinds
of information than it is for any other universe or kind
of population I have discussed before.
There is really no census material on who used
Pyrex. There is inadequate information on who owns new
Ramblers, and there is not much information on who switched
from Marlboros to L § Ms last week.
Q But the kind of characteristics which I have
described are -- I assume what you are saying is that
they are readily identifiable?
A That is right.

0 Could you describe how the random sampling
technique could be adapted to the selection within
Lowndes County, for example, of a cross-sectional list
of prospective jurors?
A I would assume that the kind of county you are
talking about, as would be true of any other county,
would have the same Bureau of the Census information
on enumeration districts, census tract or block statistics
as any census would.
0 You are referring, I assume, to the Federal
decennial census.
A That's right. And in using this information, you
should select at random and‘impartially a relevant
number of enumeration districts which would be designed
to provide the number of jurors which might be needed.
For example, in that county you might pick forty
blocks, or forty enumeration districts, depending upon
the characteristics of the county, and within each of
those randomly selected blocks do what in effect would
be a census of every fifth household in those blocks,
and within those households make a random selection of
citizens eligible to serve on juries -- that is to say,
men and women over 21, upper income and lower income
people, whites and Negroes, and so on.

Q And it wouldn’t affect your judgment, would it,
if, as in Alabama, women are restricted from jury service?
Your technique would be adapted to that fact, would it
not?
A Well, there would be two approaches we would
consider. We could automatically eliminate, again, in
scientific fashion, the women from such a sampling or,
on the other.hand, they could be included in a sampling,
which would necessarily be a larger sampling, in
anticipation of most of these women expressing a disinclinp
tion to serve on a jury.
0 Would it be very difficult to set up the
mechanics of operating a jury selection system on a random
sampling basis?
A I assume you mean from the point of view of a
local --
0 Could a local resident of Lowndes County, of
common intelligence and average education, do whatever
would be necessary in order to set up and, administer
such a jury selection system?
A Yes, but with this qualification:
The sampling approach T have been talking about
would have to be summarized for that local person
to put into action.

The summarization could be simple and quite
straightforward, perhaps adding up to a page or two or
three of directions specifying such things as, "Go to
the corner of Maple and Ash Streets and get the names of
the people in every third household", as I have described
the procedure earlier.
0 So this initial preparation would have to be
done by experts, but it could be implemented with
easily-understood instructions?
A Yes, but the experts would not have to take a
great deal of time to set up such a system.
For someone trained in the business of sample
selection, it would be a relatively straightforward and
simple operation provided the kind of census material
I have talked about were made available.
It could be done, for example, I am sure, by people
in the Bureau of Labor Statistics within a state, or
a Chamber of Commerce, or comparable organizations with
census material available.
0 Do you know of any other system of selection
which might achieve the same accurate cross-sectional
results in the jury selection process as the random
sampling technique you have described?
A No. There is none that we have heard of and none

that we have been able to discover.
Q As you no doubt know, there are a variety
of selection techniques used in drawing jurors around
the country, not including the random sampling techniques
but rather using such devices as telephone directories
or property tax rolls or gas and electric company
records or voting records.
Do you have an opinion about the cross-
sectional accuracies of those kinds of lists?
A Yes. And let me take up a couple of them.
You mentioned telephone listings. In some sections
of the country, for example in New York City, there are
as many as 400,000 unlisted telephones, so that any
survey sample is going to omit representation of the
kinds of people who do not want their telephones listed
in New York City.
For quite different reasons, there are many
unlisted telephone numbers in a city like Houston.
Secondly, where telephones are concerned, this is
an expense,so that resorting to telephone listings would
automatically exclude from any sound sampling procedure
those people who are too poor, or consider themselves to
be too poor, to have a telephone in the home.
In other words, you would have a bias in the

direction of upper income people by going to the
telephone listings in this situation.
Taking the example of the utilities, in many rural
areas there are a great many people who still rely on
coal, kerosense, candlelight and just plain daylight,
and resorting to such lists would, again, automatically
exclude people who were too poor, or too far down the
economic ladder, to afford utility service.
You mentioned voter lists. There are wild
variations in this area because a great many people in
a great many counties are unregistered, or just do not
vote or, in fact, in counties or states where there is
a large transient population, inevitably an effort to use
voting lists may omit as many as 15 to 25 per cent of
the resident population.
You also mentioned using property tax rolls.
Again, this strikes against lower income people, whether
they be people with large families, people who are
sporadically employed, or what have you.
0 Is there any kind of list, except census
material, which can be used to get a representative
c t o s s -section of a given population?
A Not if you are undertaking to do a survey, for

a product which is in general use throughout a county,
a state or a region.
You can, of course, go to specific lists where you
have a very narrowly defined population, such as
subscribers to a magazine, or new car owners, as I
suggested earlier, but that would be doing a disservice
to the client and guaranteeing, in fact, inaccuracies
to do a survey, for example, for a political client from
some of the lists we have been discussing here, because
we would be guaranteeing the omission of key groups of
people, such as women, people who didn't own property,
people who didn't own telephones, people who preferred
kerosene to electric power, and so forth.
0 In your opinion, Mr. Kraft, what would be
the cross-sectional accuracy of a list of jurors
selected by jury commissioners, for example, on the
basis of their personal acquaintances or by their
writing large numbers of letters to different groups of
people, or even to individuals within a community?
A Well, if they were to communicate with their
friends and acquaintances, they just conceivably might be
reproducing a cross-section of their friends and
acquaintances, but they certainly wouldn't be reproducing
a cross-section of a total population in an area because

it is an incredibly rare person who has an acquaintance
ship with a representative cross-section of an entire
population.
With regard to writing letters to large numbers of
people, first we have to face the problem of whether or
not mail delivery is available to all of the people in
the population, whether addresses are correct and
whether in fact his signature will spur or discourage
response to his letter.
So the two examples you ask about seem to me to
insure unrepresentativeness, quite the opposite from
a representative cross-section.
0 In the random sampling selection technique
of jurors which you have described,is there any room
whatsoever for the exercise of subjective discretion in
the selection of jurors by the persons administering the
selecton process?
That is to say, do the personal preferences of
the person administering this random sample jury selection
technique enter into the selection process at all?
A Not the process we have been describing, not in any
way.
Let me explain it this way: The whole focus of
our approach is to remove human discretion from

scientific sampling, to remove the possibility of
bias in selecting the sample, and the kind of sample
selection I have been describing here is one which will
effectively do that, and I believe it is really the only
way to insure selecting a random representative cross-
section of a given population and be totally unbiased.
0 In conclusion, do you know of any system
other than the random sampling system based upon
Federal census material that can produce the same highly
accurate cross-section of a population?
A There would be no other material available as of
right now to produce a better approach.
There is another system, though, which might be
employed, which would in effect add up to a re-census.
I will explain that last by saying that you could impose
a geographic grid system on a state or country or county
or town you are concerned about, and then select squares
from that grid, and if you will visualize a grid system
of let's say 100 by 100 squares, for a total of 10,000
squares, in other words, you could select at random
some 100 squares and do a census within each one of
those squares of the adult population,and then apply
similar methods to those that I have described earlier,
which is to say, a random sampling of people within each

of those squares proportionate to the distribution of
the population.
0 Doesn't that in effect come to the same
thing as the random sampling technique?
A In effect, yes, it does.
It is more complicated and more complex, and it is
a harder way to do it, and you would only employ it in
the absence of adequate census material.
0 Do you have any douht about the feasibility
and the practicality of applying random sampling
techniques to the jury selection process?
A No, I don't, if it would be understood that a
random sampling technique in the county you mentioned
earlier with the population of 15,000 were to be based
on, for example, a cross-section of 1,000 potential
members of a panel -- well, it is possible that we might
under-represent or over-represent upper income people
to the tune of one per cent or two per cent, and
similarly, we might over or under-represent people with
large families by one or two per cent -- but if this
margin of error on that kind of a sample is acceptable,
which it is in my opinion, then there is absolutely
no question that this is the sound and proper approach.
0 You wouldn't think that would be a critical
