LAY, Chief Judge.

The issues on this appeal relate to the question left open in Witherspoon v. Illinois, 391 U.S. 510, 88 S.Ct. 1770, 20 L.Ed.2d 776 (1968): whether the exclusion of jurors who hold absolute scruples against the death penalty creates a "conviction-prone" jury as to the guilt of a defendant in a capital case. On an earlier remand from this court, Grigsby v. Mabry, 637 F.2d 525 (8th Cir. 1980), modifying 483 F. Supp. 1372 (E.D.Ark. 1980), the district court held a plenary hearing on the issues involved: (1) whether the sixth amendment right to a trial by jury is violated in capital cases by a jury from which the state has systematically excluded at voir dire all persons who hold inflexible scruples against capital punishment and (2) whether exclusion of the Witherspoon excludables (WEs) during the guilt-innocence phase of the trial violates a defendant's fourteenth amendment due process right to a fair and impartial jury. The trial court, the Honorable G. Thomas Eisele, in a learned and exhaustive opinion, found that both the sixth amendment right to have a jury selected from a representative cross section of the community, and the fourteenth amendment due process right to have an impartial jury, were violated. As a result, the trial court ordered that the state of Arkansas, in all capital cases, must hold bifurcated jury trials; first, as to guilt, and second, assuming guilt, as to punishment. Grigsby v. Mabry, 569 F. Supp. 1273, 1321-23 (E.D.Ark. 1983). Stay granted 583 F. Supp. 629 (E.D.Ark. 1983).

Based on the overall exhaustive record, we find substantial evidentiary support for the district court's findings. We find that substantial evidence supports the court's finding that a capital jury, with WEs stricken for cause, is in fact conviction prone and, therefore, does not constitute a cross-sectional representation in a given community. In view of our finding on the sixth amendment violation, it is unnecessary to discuss the issue whether the jury in the petitioners' cases was in fact a biased jury. We affirm, with modification, the judgment of the district court. We vacate that portion of the district court's judgment which requires the state to utilize two separate juries; one to determine guilt-innocence and another for the penalty phase of the trial. We leave the actual procedural remedy to the discretion of the state.

Although this was originally a consolidated proceeding, the district court granted a writ of habeas corpus only to the petitioner Ardia McCree. McCree was convicted of capital murder in Ouachita County, Arkansas in 1978. He is presently serving a life sentence without parole. His conviction was affirmed by the Arkansas Supreme Court. See McCree v. State, 266 Ark. 465, 585 S.W.2d 938 (1979). In McCree's trial, eight prospective jurors were excused for cause on the ground that they could not impose the death penalty. McCree made a timely objection to the exclusion of WEs in the guilt-innocence phase. Moreover, in the present case, the state expressly has waived any claim of exhaustion of remedies or other procedural bar.

I.

In Duren v. Missouri, 439 U.S. 357, 364, 99 S.Ct. 664, 668, 58 L.Ed.2d 579 (1979), the Supreme Court stated:

In order to establish a prima facie violation of the fair-cross-section requirement, the defendant must show (1) that the group alleged to be excluded is a "distinctive" group in the community; (2) that the representation of this group in venires from which juries are selected is not fair and reasonable in relation to the number of such persons in the community; and (3) that this underrepresentation is due to systematic exclusion of the group in the jury-selection process.

And in an earlier opinion, Taylor v. Louisiana, 419 U.S. 522, 538, 95 S.Ct. 692, 702, 42 L.Ed.2d 690 (1975), the Court stated:

[T]he jury wheels, pools of names, panels, or venires from which juries are drawn must not systematically exclude distinctive groups in the community and thereby fail to be reasonably representative thereof.

A threshold contention of the state here is that the cross-sectional requirement of the sixth amendment is not applicable to a petit jury. In making this argument the state relies on statements taken from Duren that such attack only applies to the panels or venires from which juries are drawn. Duren, 439 U.S. at 363-64, 99 S.Ct. at 668. Similarly, the state cites from Taylor the abstraction that "we impose no requirement that petit juries actually chosen must mirror the community and reflect the various distinctive groups in the population." Taylor, 419 U.S. at 538, 95 S.Ct. at 702. The state also argues that this court rejected a sixth amendment attack on a petit jury in United States v. Childress, 715 F.2d 1313 (8th Cir. 1983), cert. denied, ___ U.S. ___, 104 S.Ct. 744, 79 L.Ed.2d 202 (1984).

Childress must be read within its factual context. The significant issue in Childress was whether an alleged systematic exclusion of blacks by the prosecution in exercising its peremptory strikes constituted a sixth amendment violation. Childress, 715 F.2d at 1314-15. We agree the state may exercise peremptory challenges as it deems necessary. See Swain v. Alabama, 380 U.S. 202, 85 S.Ct. 824, 13 L.Ed.2d 759 (1965); but see Williams v. Illinois, ___ U.S. ___, 104 S.Ct. 2364, 80 L.Ed.2d 836 (1984) (Marshall, J., dissenting); Gilliard v. Mississippi, ___ U.S. ___, 104 S.Ct. 40, 78 L.Ed.2d 179 (1983) (Marshall, J., dissenting). No stated reason is necessary in exercising peremptory challenges. To establish a rule that jurors cannot be stricten by peremptory challenges on certain grounds seeks the impossible and limits the right of a party to eliminate jurors who appear to be biased. A correlative to Childress is the concept that no defendant has the right to select biased jurors who he feels might be more sympathetic to his case.

It would, of course, be impossible to obtain a petit jury that reflects all the distinctive groups in a community. In this sense it is easy to conclude that systematic exclusion, as it relates to the necessity of having a cross-sectional jury, is generally not an issue when dealing with the petit jury. Nevertheless, in given factual instances, the sixth amendment requirement of cross-sectional representation has been held applicable to the petit jury. See Adams v. Texas, 448 U.S. 38, 50, 100 S.Ct. 2521, 2529, 65 L.Ed.2d 581 (1980); Ballew v. Georgia, 435 U.S. 223, 236-37, 98 S.Ct. 1029, 1037-38, 55 L.Ed.2d 234 (1978); Witherspoon, 391 U.S. at 518-23, 88 S.Ct. at 1775-78. There is no justifiable reason to conclude that a statute which systematically eliminates distinct groups of citizens from sitting on a petit jury would not violate the sixth amendment requirement of a representative cross-sectional jury. We deal here with a right to eliminate for cause a distinctive group of prospective jurors. If prospective jurors, who would take an oath to decide a case on the basis of the law and facts presented, could be excluded for cause because they were white or black, or, based on questions elicited on voir dire, because they were pro-ERA, pro-life, Republicans or Democrats, such a systematic exclusion from the panel, would encroach upon a party's sixth amendment right to have a cross-sectional Jury.

We base our rejection of the state's argument on decisions of the Supreme Court. In Swain the Court noted that systematic exclusion from a petit jury of a distinctive group over a long period of time would be wrong. Swain, 380 U.S. at 223-24, 85 S.Ct. at 837-38. In Ballew v. Georgia, 435 U.S. 223, 98 S.Ct. 1029, 55 L.Ed.2d 234 (1978), the Court held that a petit jury of less than six persons would violate a defendant's sixth amendment right to have a cross-sectional representation. Id. at 230, 245, 98 S.Ct. at 1034, 1041. See also Williams v. Florida, 399 U.S. 78, 100-01, 90 S.Ct. 1893, 1905-06, 26 L.Ed.2d 446 (1970). And finally, Witherspoon itself is direct authority that a distinctive group, eliminated for cause from the petit jury, violates the sixth amendment principle that requires a cross-sectional jury. As Justice Stewart noted, in response to the argument that no actual prejudice had been shown: "But it is self-evident that, in its role as arbiter of the punishment to be imposed, this jury fell woefully short of that impartiality to which the petitioner was entitled under the Sixth and Fourteenth Amendments." Witherspoon, 391 U.S. at 518, 88 S.Ct. at 1775 (our emphasis). The Court went on to state:

Guided by neither rule nor standard, "free to select or reject as it [sees] fit," a jury that must choose between life imprisonment and capital punishment can do little more — and must do nothing less — than express the conscience of the community on the ultimate question of life or death. Yet, in a nation less than half of whose people believe in the death penalty, a jury composed exclusively of such people cannot speak for the community. Culled of all who harbor doubts about the wisdom of capital punishment — of all who would be reluctant to pronounce the extreme penalty — such a jury can speak only for a distinct and dwindling minority.

* * * * * *

Specifically, we hold that a sentence of death cannot be carried out if the jury that imposed or recommended it was chosen by excluding veniremen for cause simply because they voiced general objections to the death penalty or expressed conscientious or religious scruples against its infliction. No defendant can constitutionally be put to death at the hands of a tribunal so selected.

Witherspoon, 391 U.S. at 519-20, 521-23, 88 S.Ct. at 1775-76, 1777 (footnotes omitted) (our emphasis).

We conclude on the facts of the present case, which involves a challenge for cause, that the state cannot defeat a sixth amendment claim on the ground that we deal only with a petit jury, rather than the jury pool at large.

II.

Turning to the specific elements of the Duren test, we find Witherspoon also is direct authority that the group of WEs excluded in this case is a distinctive group in the community. Witherspoon found a distinctive group in those venirepersons who were not "automatic-life" but still had scruples against the death penalty. The district court found "that the [ Witherspoon excludable] group is of substantial size both nationally and within the state of Arkansas, ranging between 11% and 17% of those eligible for jury service. So the group excluded is both distinct and sizeable." Grigsby, 569 F. Supp. at 1285.

The second element of the Duren test relates to venires. However, given our earlier discussion and finding that there is no practical difference between exclusion from the venire and systematic exclusion for cause from the petit jury, we analyze the resultant petit juries. In this case we find the representation of WEs on the juries is not "fair and reasonable in relation to the number of such persons in the community * * *." Duren, 439 U.S. at 364, 99 S.Ct. at 668. The district court found WEs constitute between eleven and seventeen percent of the population. However, WEs are totally excluded from guilt-innocence juries in Arkansas.

Finally, Duren requires the petitioners to establish that the WEs are systematically excluded. Here, the district court found the systematic exclusion results from the voir dire at trial. Grigsby, 569 F. Supp. at 1286. There is little argument offered by the state that in capital cases the exclusion is not systematic.

III.

It is necessary to emphasize that this case concerns only the exclusion of WEs from the guilt-innocence phase of a capital trial. The exclusion of jurors who will never consider a penalty of death, approved in Witherspoon, becomes irrelevant when the focus is on the first half of a bifurcated trial; on the guilt-innocence phase, rather than the penalty determination. Witherspoon does not hold that jurors unalterably opposed to the death penalty, but who nonetheless can swear to consider the evidence and follow the law in determining guilt, can be excluded from the guilt-innocence phase of a bifurcated trial.

The fundamental issue facing the court is whether the evidence supports the district court's finding that a jury with WEs stricken for cause is a conviction-prone jury. If the evidence supports this finding then we feel McCree has established his case that there has been a denial of his sixth amendment right. This conclusion finds analogous support in the Witherspoon court's holding that exclusion for cause of venirepersons who opposed the death penalty, but were found not to be automatic-life — i.e., able to consider the evidence and follow the law — created "a tribunal organized to return a verdict of death." Witherspoon, 391 U.S. at 521, 88 S.Ct. at 1776. Since the district court has exhaustively analyzed this evidence, see Grigsby, 569 F. Supp. at 1291-1308, we need only summarize the proofs.

A. Attitudinal and Demographic Surveys [18] 1. Bronson, On the Conviction Proneness and Representativeness of the Death-Qualified Jury: An Empirical Study of Colorado Veniremen, 42 U.Colo.L.Rev. 1 (1970). ( Bronson-Colorado).

The subjects of this study were 718 Colorado venirepersons. Interviews were done by trained students from the University of Colorado in 1968 and 1969. Each subject was asked whether they strongly favored, favored, opposed, or strongly opposed the death penalty. This was followed by five questions regarding attitudes on criminal justice issues. On each of the five questions the survey found the stronger the subjects' support for the death penalty, the stronger their support for positions most favorable to the prosecution.

2. Bronson, Does the Exclusion of Scrupled Jurors in Capital Cases Make the Jury More Likely to Convict? Some Evidence from California, 3 Woodrow Wilson L.J. 11 (1980). ( Bronson-California).

Two studies similar to the Bronson-Colorado survey are grouped together in this article. Trained students interviewed 755 Butte County, California, venirepersons regarding their position on the death penalty. Seven attitudinal questions, much like those used in Bronson-Colorado, followed. Once again a direct and significant correlation between death penalty beliefs and criminal justice attitudes was found.

The second survey involved interviews of 707 venirepersons from Los Angeles, Sacramento and Stockton, California. The results were consistent with the prior studies: the more strongly the subjects favored the death penalty, the more likely they were to endorse pro-prosecution positions.

3. Louis Harris Associates, Inc., Study No. 2016 (1971).

Harris randomly polled 2,068 adults throughout the United States in 1971. The respondents were asked about their attitudes on the death penalty and other criminal justice issues. The results parallel those of the Bronson surveys. In addition, Harris found more blacks than whites, and more women than men, would be excluded from jury service by death qualification.

4. Fitzgerald Ellsworth, Due Process vs. Crime Control: Death Qualification and Jury Attitudes, 8 Law Hum. Behav. 31 (1984). ( Fitzgerald 1979).

The survey upon which this article is based was a sample of 811 jury eligible persons in Alameda County, California, in 1979. An independent professional polling organization, Field Research Corporation of San Francisco, drew the sample and interviewed the subjects. Respondents who could not be fair and impartial, i.e., nullifiers, were excluded. Of the remaining 717 subjects, over seventeen percent were found to be WEs. Questions regarding attitudes on criminal justice issues showed that death qualified respondents were more favorable to the prosecution than the WEs.

5. Precision Research, Inc., Survey No. 1286 (1981). ( Precision Survey).

This survey was conducted by an Arkansas polling organization in 1981. A sample of 407 adults in the state of Arkansas were asked the same questions used in Fitzgerald-1979. The survey found that approximately eleven percent of those who could be fair and impartial in determining guilt-innocence were WEs.

B. Conviction-Proneness Surveys [30] 1. H. Zeisel, Some Data on Juror Attitudes Toward Capital Punishment (University of Chicago Monograph 1968). ( Zeisel).

In 1954 and 1955 Zeisel questioned jurors who had served on felony juries in Brooklyn, New York, and Chicago, Illinois. The subjects were asked about the first ballot votes of their jury and whether they had scruples against the death penalty. The study controlled for the weight of evidence in each case and found jurors with conscientious scruples against the death penalty voted to acquit more often than jurors without such scruples.

2. W. Wilson, Belief in Capital Punishment and Jury Performance (1964) (unpublished). ( Wilson).

This study presented 187 college students with written descriptions of five capital cases in 1964. Each student was asked whether he or she had scruples against the death penalty. They were then asked to assume that they were jurors in the five cases. The students without death penalty scruples voted for conviction more often than those with scruples.

3. Goldberg, Toward Expansion of Witherspoon: Capital Scruples, Jury Bias, and Use of Psychological Data to Raise Presumptions in the Law, 5 Harv.C.R.-C.L.L.Rev. 53 (1970).

A set of sixteen written descriptions were given to 100 white and 100 black college students in Georgia. Those without scruples voted to convict in seventy-five percent of cases, compared to sixty-nine nine percent for those with scruples.

4. Jurow, New Data on the Effect of a "Death Qualified" Jury on the Guilt Determination Process, 84 Harv.L.Rev. 567 (1971). ( Jurow).

Audio recordings of two simulated murder trials were played for 211 employees of Sperry Rand Corporation in New York. The subjects filled out questionnaires which measured their attitudes toward the death penalty and various criminal justice issues. The subjects were then asked to listen to each "trial" and vote on guilt-innocence. Those persons who more strongly favored the death penalty were found to be more likely to convict.

5. Cowan, Thompson Ellsworth, The Effects of Death Qualification on Jurors' Predisposition to Convict and on the Quality of Deliberation, 8 Law Hum. Behav. 53 (1984). ( Cowan-Deliberation).

This 1979 study began by identifying the WEs in its sample of jury eligible residents of San Mateo and Santa Clara Counties, California. Those WEs who could not be fair and impartial in determining guilt-innocence (nullifiers) were excluded from the sample. The remaining 288 subjects were shown a realistic two and one-half hour videotape of a murder trial. The subjects filled out questionnaires regarding their criminal justice attitudes and were assigned to panels of twelve in order to simulate jury deliberations. Some panels were death qualified, while others included WEs. Ballot forms were filled out by each subject before and after the panel deliberations as a means of examining the quality and importance of the deliberations.

The study found that death penalty attitudes were closely linked to conviction proneness — subjects favoring the death penalty were more likely to convict. In addition, the study concluded that jury panels containing a mix of WEs and death-qualified subjects tended to view all witnesses more critically and remember the facts of the case more accurately than death-qualified jury panels.

C. Other Surveys [42] 1. Thompson, Cowan, Ellsworth Harrington, Death Penalty Attitudes and Conviction Proneness, 8 Law Hum. Behav. 95 (1984). ( Thompson-Attitudes).

A videotape of two witnesses' conflicting testimony in a criminal trial was shown to twenty death-qualified subjects and sixteen WEs, all of whom had participated in the Cowan-Deliberation survey. The subjects then filled out a questionnaire regarding the testimony they had viewed. The death-qualified subjects gave answers more favorable to the prosecution than the WEs.

2. Haney, On the Selection of Capital Juries: The Biasing Effects of the Death-Qualification Process, 8 Law Hum. Behav. 121 (1984).

This study investigated the process of death qualification on the jurors who undergo it. A sample of sixty-seven jury eligible residents of Santa Cruz County, California were selected after screening out those who could not be fair and impartial in determining guilt-innocence (nullifiers). The subjects were randomly divided into two groups and shown a realistic two hour videotape of a murder trial. One group, in addition, saw a half-hour of voir dire in which prospective jurors were death qualified. The study found that the members of the group which viewed the voir dire were more likely to believe the defendant was guilty than members of the other group.

3. A. Young, Arkansas Archival Study (1981) (unpublished). ( Arkansas Study).

This study consisted of a review of forty-one transcripts of voir dires in capital cases from 1973 to 1981 which were on file at the Arkansas Supreme Court. The survey found that over fourteen percent of the venirepersons were WEs and one-half of one percent were ADPs.

D. Expert Testimony 1. Edward J. Bronson, B.S., J.D., LL.M., Ph.D.

Dr. Bronson is a Professor of Public Law and Political Science at California State University at Chico. He has experience working with a variety of officials in the criminal justice system including prison officials, law enforcement officers, and parole officers. At trial, Dr. Bronson testified for petitioners about his own empirical evidence and evidence developed by others. He discussed how death qualification affects the attitudes and demographic composition of the resulting juries.

2. Craig W. Haney, B.A., M.A., Ph.D., J.D.

Dr. Haney is a Professor of Psychology at the University of California, Santa Cruz. He has conducted research on a wide range of criminal justice subjects including plea bargaining, eye witness testimony, the effects of television on witness perception, the impact of imprisonment on personality and the effects of voir dire on prospective jurors. Dr. Haney's testimony for petitioners concerned the relationship between death penalty attitudes and other criminal justice attitudes. In addition, Dr. Haney presented his study on how death qualification voir dire tends to bias the resulting jury against the defendant.

3. Reid Hastie, B.A., M.A., Ph.D.

Dr. Hastie is a Professor of Psychology at Northwestern University. He has focused his research on juries and their decision-making process. In his testimony for petitioners, Dr. Hastie reviewed research on the effect of death qualification on the resulting jury and the quality of that jury's deliberation and fact finding. He also compared the relative conviction proneness of death-qualified and nondeath-qualified juries.

4. Gerald H. Shure, B.S., Ph.D.

Dr. Shure is a Professor of Psychology and Sociology at the University of California, Los Angeles. His research in the field of jury behavior is limited; however, Dr. Shure has considerable expertise in the effects of communication channels in problem solving, bargaining and negotiation, and pacifist behavior. Dr. Shure, in his testimony for the state, critiqued petitioners' studies and offered one of his own.

E. Discussion

After examining all of the surveys and considering extensive testimony, the district court concluded that petitioners had proven a jury with WEs stricken for cause is a conviction-prone jury. Grigsby, 569 F. Supp. at 1293-1305. The district court found that "[a]lthough Dr. Shure has made some reasonable criticisms and suggestions concerning the possibility of improving research techniques and better interpretation of existing studies, he has not, in his general comments, successfully impeached the clear thrust and effect of petitioner's [sic] case." Grigsby, 569 F. Supp. at 1307. Dr. Shure's own study did not contradict the basic findings introduced by petitioners and he acknowledged there were problems with his results. Id. at 1307-08. Indeed, the district court found "[i]n many ways his testimony reinforces that of the petitioners' experts." Id. at 1307. Judge Eisele was impressed with the consistency of all evidence in supporting the conclusion that death-qualified juries are conviction prone. Id. at 1307, 1322-23.

On appeal, the state challenges petitioners' evidence on many grounds: (1) petitioners compared the wrong groups — WEs versus death-qualified jurors instead of WEs and ADPs versus death-qualified jurors; (2) petitioners succeeded in showing only that WEs are biased because they are more acquittal prone than death qualified jurors; and (3) the behavior of jurors cannot be predicted on the basis of the studies and testimony presented. Moreover, Arkansas complains that much of the evidence was based on statistical significance, which the state calls "the lowest form of proof."

Arkansas' first argument is based on the fact that some of the early studies do not identify WEs or properly differentiate between WEs and death-qualified jurors. In addition, the state contends petitioners have failed to account for ADPs. Of course the pre- Witherspoon studies did not specifically identify WEs, nonetheless they do show that death penalty attitudes are directly related to general criminal justice attitudes and conviction proneness. The later studies identified WEs properly and their results were consistent with the earlier ones. Later studies also identified ADPs and found them to be a negligible group. For this reason we are not limited in our conclusions the way the California Supreme Court was in Hovey v. Superior Court, 28 Cal.3d 1, 63-64, 616 P.2d 1301, 1343-44, 168 Cal.Rptr. 128, 170-71 (1980).

The focus on particular groups of jurors does give insight into the difference between a death-qualified jury and a normal criminal jury. The state argues that the comparison should center on the two types of juries rather than the characteristics of WEs and death-qualified jurors. However, by examining and defining the elements of the normal criminal jury which are missing on a death-qualified jury — the WEs and ADPs — reasonable conclusions about the differences between the two juries can be drawn. In addition, one study did compare death-qualified with nondeath-qualified panels.

Arkansas next echoes the Fifth Circuit's argument that the only thing the evidence shows is WEs are acquittal prone. The state contends petitioners have not proved death-qualified juries are necessarily biased. First, we must note the systematic exclusion of any distinct qualified group from jury service violates the cross-sectional requirement of the sixth amendment whatever the bias of that group. As we discussed previously, WEs who can follow the law and fairly try guilt-innocence are a distinct qualified group. Second, the state ignores its own previous argument that the proper comparison is not between WEs and death-qualified jurors but, instead, between a normal criminal jury and a death-qualified jury. The evidence presented by petitioners amply supports the district court's finding that death-qualified juries are more conviction prone than a normal criminal jury.

Arkansas also contends that the behavior of real jurors cannot be predicted from the studies presented by petitioners. However, some of the studies included real jurors, and one involved a realistic simulation of jury deliberations. The state of California raised the same objection in Hovey and it was flatly rejected. Hovey, 28 Cal.3d at 61-62, 616 P.2d at 1342, 168 Cal. Rptr. at 169. Furthermore, it is the courts who have often stood in the way of surveys involving real jurors and we should not now reject a study because of this deficiency.

Finally, Arkansas complains about the court's reliance on social science data and belittles its statistical significance. Other courts have accepted some of the studies presented here and similar social science data. See Keeten v. Garrison, 578 F. Supp. 1164, 1171-77 (W.D.N.C.), rev'd, 742 F.2d 129 (4th Cir. 1984); Hovey, 28 Cal.3d at 26-60, 616 P.2d at 1314-41, 168 Cal.Rptr. at 141-68. Moreover, in Witherspoon, the Supreme Court invited development of this type of evidence. Witherspoon, 391 U.S. at 517, 520 n. 18, 88 S.Ct. at 1774, 1776 n. 18. In other sixth amendment cases the Supreme Court has relied on similar data. See Ballew v. Georgia, 435 U.S. 223, 232-39, 98 S.Ct. 1029, 1035-39, 55 L.Ed.2d 234 (1978); Colgrove v. Battin, 413 U.S. 149, 158-60, 93 S.Ct. 2448, 2453-54, 37 L.Ed.2d 522 (1973); Williams v. Florida, 399 U.S. 78, 101-02, 90 S.Ct. 1893, 1906-07, 26 L.Ed.2d 446 (1970). All of the studies introduced were consistent in their conclusions that death penalty attitudes are related to criminal justice attitudes and conviction proneness. Arkansas introduced no contrary studies. The consistency over a wide range of survey methods and respondents is impressive. The state's attack is not well founded. The district court's finding of fact that a petit jury without WEs is "conviction prone" and, therefore, not an impartial or cross-representative jury is not clearly erroneous.

The state raises two additional issues which merit discussion. First, the question is raised whether or not those who are not WEs, but still possess scruples against the death penalty, will adequately represent WEs on the jury so as to nullify the argument that the jury is conviction prone or not cross-representative. The second question is whether the fact that ADPs are excluded from the jury in Arkansas undermines the studies relied upon by the district court. Cf. Hovey, 28 Cal.3d at 63-69, 616 P.2d at 1343-47, 168 Cal.Rptr. at 170-74.

The district court rejected both arguments. We agree with its conclusions. In considering the first argument, the court addressed our holding in United States v. Olson, 473 F.2d 686 (8th Cir.), cert. denied, 412 U.S. 905, 93 S.Ct. 2291, 36 L.Ed.2d 970 (1973), and found there was no evidence in that case to suggest that the criminal justice attitudes of the excluded eighteen to twenty year old group would not be represented by other eligible jurors. Grigsby, 569 F. Supp. at 1282-83. By contrast, in this case, the district court found that one element of the WEs' distinctiveness as a group is that no other group of death-qualified jurors shared their attitudes or perspectives. Id. at 1283. The court considered petitioners' attitudinal studies and concluded: "[s]uch evidence undercuts the idea that the mildly scrupled jurors who are not excluded under Witherspoon would adequately represent the attitudes of those who are excluded under Witherspoon." Id.

Turning to the second argument, the district court noted "the State, by embracing the ADP issue, has effectively conceded the validity of the a priori, intuitive, gut feelings of all who actively and routinely participate in jury cases in nisi prius courts — the 'fireside induction' — that WEs are acquittal prone and ADPs are conviction prone." Id. at 1306. The court also pointed out that the present case can be distinguished from Hovey because "the Court in Hovey, like the United States Supreme Court in Witherspoon, did not feel that it had adequate empirical data before it to permit it to deal with the important constitutional issues at stake." Id. In this case the ADP issue was squarely addressed and both expert testimony and an empirical study were introduced by the state. The district court found that neither significantly undermined the studies presented by petitioners. Id. at 1307-08. Furthermore, Arkansas' expert admitted there were basic deficiencies in his survey. Id. The court concluded the number of ADPs was negligible and found that their removal from a death-qualified jury "contributes only to the appearances of fairness." Id. at 1308.

In upholding the district court's finding based upon the evidentiary record we must note: (1) the record here is exhaustive; it is difficult to perceive how any petitioner could make a record and an objection to death-qualified juries, as constituting an improper jury for the determination of guilt-innocence, more complete than that presented here; and (2) there are no studies which contradict the studies submitted; in other words, all of the documented studies support the district court's findings.

IV.

Only a few cases have been decided with a similar question. We note Hovey in California, the Fifth Circuit cases of Smith v. Balkcom, 660 F.2d 573 (5th Cir. 1981), modified, 671 F.2d 858 (5th Cir.), cert. denied, 459 U.S. 882, 103 S.Ct. 181, 74 L.Ed.2d 148 (1982), and Spinkellink v. Wainwright, 578 F.2d 582 (5th Cir. 1978), cert. denied, 440 U.S. 976, 99 S.Ct. 1548, 59 L.Ed.2d 796 (1979), and the well-written opinion of Judge McMillan of the district court in North Carolina, Keeten v. Garrison, 578 F. Supp. 1164 (W.D.N.C.), rev'd, 742 F.2d 129 (4th Cir. 1984). We are very much aware that our affirmance of the district court here creates a conflict among circuits; this is an important issue since the decision relates to hundreds of prisoners now on death row. We are hopeful the Supreme Court will grant a writ of certiorari and resolve the issue. However, in doing so, it is our hope that the Supreme Court will agree with this court that the record is no longer fragmentary and now presents the issue with proofs adequate for review.

Nonetheless, although we are not fully cognizant of the records presented in Spinkellink and Keeten, in all due respect, we cannot follow the reasoning of our sister circuits. First, and foremost, it would appear that Spinkellink, without an evidentiary record, concluded as a matter of law that there can be no constitutional violation. See Spinkellink, 578 F.2d at 593-98. As we will discuss, we disagree and feel this approach forecloses the invitation within Witherspoon that a litigant "in some future case might still attempt to establish that the jury was less than neutral with respect to guilt." Witherspoon, 391 U.S. at 520 n. 18, 88 S.Ct. at 1776 n. 18 (emphasis original). The reasoning of Spinkellink, however, was adopted by the Fourth Circuit in Keeten, despite the fact that the court had before it an evidentiary record somewhat modeled after the trial here. See Keeten, 742 F.2d at 133-34.

We feel the reasoning of Spinkellink and Keeten fails to analyze or decide the fundamental issue. In Spinkellink the court observed:

The petitioner complains of jury partiality. He alleges that the * * * "death-qualified" jury that [tried him] was "prosecution-prone." From this he concludes, by implication, that a nondeath-qualified jury * * * would be impartial with respect to the question of guilt or innocence. This is not necessarily so. When the petitioner asserts that a death-qualified jury is prosecution-prone, he means that a death-qualified jury is more likely to convict than a nondeath-qualified jury. Proof that this proposition is true is far from conclusive, but for the moment we will assume its validity. Even if it is true, the petitioner's contention still must fail. That a death-qualified jury is more likely to convict than a nondeath-qualified jury does not demonstrate which jury is impartial. It indicates only that a death-qualified jury might favor the prosecution and that a nondeath-qualified jury might favor the defendant.

Spinkellink, 578 F.2d at 593-94 (footnotes omitted).

We think this not only closes the door, as a matter of law, for a petitioner to present an empirical record to the contrary, but also fails to understand the fundamental issue.

In adopting this reasoning, the Keeten court followed Spinkellink and added that "members of the venire who are irrevocably opposed to capital punishment would engage in jury nullification if permitted to sit at the guilt stage of a capital case and, therefore, would not be impartial fact finders." Keeten, 742 F.2d at 133. And, in rejecting the due process claim, the court again followed Spinkellink's faulty reasoning:

The fact that a death-qualified jury may be more conviction prone than one which includes jurors strongly opposed to the death penalty does not demonstrate which jury is impartial. Rather, "[i]t indicates only that a death-qualified jury might favor the prosecution and that a nondeath-qualified jury might favor the defendant." Spinkellink v. Wainwright, 578 F.2d at 594.

Keeten, 742 F.2d at 134. This analysis misses the point. The issue is not whether a jury would be biased one way or the other, but whether an impartial jury can exist when a distinct group in the community is excluded by systematically challenging them for cause. As the district court noted, the petitioners were not seeking a jury composed entirely of WEs; what petitioners sought was a "jury drawn from the entire cross section of the community as a whole, including both those who strongly favored the death penalty and those who strongly opposed it." Grigsby, 569 F. Supp. at 1311.

Judge James McMillan, one of America's most distinguished trial judges, observed in the district court opinion in Keeten:

Common sense suggests that people who favor the death penalty are more likely to convict defendants charged with capital crimes, and that people who do not favor the death penalty are less likely to convict defendants charged with capital crimes. The Supreme Court recognized those contentions in Witherspoon v. Illinois, 391 U.S. 510, 88 S.Ct. 1770, 20 L.Ed.2d 776 (1968), but prudently did not then adopt them as a basis for decision because of the lack of sociological testimony, juror opinion polls and other evidence.

Such evidence has now been developed and occupies hundreds of pages of the record of these cases.

A fair jury has not been provided when the prosecutor is able to keep on the jury those persons most likely to convict and to exclude from the jury for cause all those persons most likely to acquit.

Nor does a jury so constituted represent, even in theory, a representative cross-section of the community.

Keeten, 578 F. Supp. at 1167.

V.

One last point urged by the state is that McCree should not succeed because there is no showing of actual prejudice. In a sixth amendment claim prejudice is not an element of proof. See, e.g., Duren v. Missouri, 439 U.S. 357, 99 S.Ct. 664, 58 L.Ed.2d 579 (1979); Ballew v. Georgia, 435 U.S. 223, 98 S.Ct. 1029, 55 L.Ed.2d 234 (1978); Taylor v. Louisiana, 419 U.S. 522, 95 S.Ct. 692, 42 L.Ed.2d 690 (1975); Peters v. Kiff, 407 U.S. 493, 92 S.Ct. 2163, 33 L.Ed.2d 83 (1972). The underrepresentation of a distinct group from a petit jury brought about by systematic challenge for cause affects the integrity of the entire jury system and no actual prejudice need be shown.

The district court recommended a bifurcated trial with two juries. In a subsequent opinion the Arkansas Supreme Court found this to be impractical and the worst of all solutions. Rector v. State, 280 Ark. 385, 396, 659 S.W.2d 168, 173 (1983). We think the procedure to be followed to secure an impartial jury in the guilt-innocence phase of a trial should be left to the states. In this regard, we modify the district court's requirement that the state utilize separate juries in a bifurcated trial. Other alternatives are apparent: selecting enough alternate jurors at the outset to replace WEs at the penalty phase; shifting the sentencing duty to the judge; or using an advisory jury at the penalty phase which need not be unanimous in its recommendation. We have no doubt that, when put to the challenge, the state will be able to construct a fair process which guarantees each defendant's sixth amendment rights.

Since Arkansas already has a bifurcated trial in capital cases perhaps the best possible procedure, rather than have two separate juries, would be to add to the number of alternates who sit in the guilt phase of trial. If the defendant is convicted a new voir dire could take place and the same jury could be qualified, with WEs excluded, to hear the penalty phase of the trial. As another alternative the WEs could be identified at the initial voir dire and a sufficient number of alternates retained to take their place on the sentencing jury. We note, however, the California Supreme Court has concluded this form of voir dire tends to bias the jury. Hovey, 28 Cal.3d at 70-73, 616 P.2d at 1347-50, 168 Cal.Rptr. at 174-77. We need not pass upon that issue at this time. Neither procedure should significantly affect the cost or efficiency of the trial.

We therefore modify the district court's direction, to the extent it mandated a bifurcated trial with two juries, but otherwise find the writ should be issued unless the state begins proceedings to re-try McCree within such reasonable time as the district court may fix. Judgment affirmed as modified.

Even so, a defendant convicted by such a jury in some future case might still attempt to establish that the jury was less than neutral with respect to guilt. If he were to succeed in that effort, the question would then arise whether the State's interest in submitting the penalty issue to a jury capable of imposing capital punishment may be vindicated at the expense of the defendant's interest in a completely fair determination of guilt or innocence — given the possibility of accommodating both interests by means of a bifurcated trial, using one jury to decide guilt and another to fix punishment. That problem is not presented here, however, and we intimate no view as to its proper resolution.
