In this opinion we construe and apply the Insanity Defense Reform Act of 1984. 1 Alvin Omega Owens was indicted and convicted for possession of a firearm in violation of 18 U.S.C.App. sec. 1202(a)(1) (as amended by the Armed Career Criminal Act of 1984 (ACCA)). 2 At trial, he presented expert witness testimony on the issue of his insanity at the time of the alleged' crime. The district court nonetheless declined to instruct the jury on insanity. Because there was sufficient evidence to require an instruction on insanity, Owens is entitled to a new trial.
BACKGROUND
In March 1986 Owens was arrested for possession of a pistol. He was later indicted for this offense: the indictment listed Owens’ five previous state convictions for burglary; it charged Owens with “unlawfully possessing] a firearm ..., which firearm had been shipped and transported in interstate commerce; all in violation of Title 18, United States Code, Section 1202(a)(1) App.” Pursuant to Fed.Rule Crim.Proc. 12.2, Owens’ attorney then filed a “Notice of Intention” indicating that “the defendant intends to rely upon the defense of insanity as of the time of the crime alleged in the indictment.”
At trial Owens attempted to describe the circumstances surrounding his arrest. 3 He testified that he was unaware that he possessed the gun in question until the police officer discovered it under Owens’ shirt; he denied ownership of the gun. 4
Another defense witness was Dr. Cook, who holds a Ph.D. and practices psychology. Dr. Cook testified regarding her evaluation of Owens in December 1985: “I gave [Owens] two personality tests, an intelligence test, a test for organic brain damage and an achievement test.... [Then,] I gave him about a twenty-minute interview.” Dr. Cook then stated that Owens “was severely emotionally disturbed and was experiencing a psychotic process and I gave him the diagnosis of simple schizophrenia.” She explained her diagnosis as follows:
[Psychosis] means that basically you’re out of touch with reality and in Mr. Owens’ case, I felt that he fluctuated in and out of touch with reality, that his problem solving ability to deal with day-to *434 day tasks was so weak and so limited that he had a very, very weak grasp of reality and at times, would lose all contact with reality.
Dr. Cook further explained that Owens’ “psychotic” state made him “unaware” of his “surroundings.” Following the testimony of Dr. Cook, Dr. Bohn, the Government’s expert, testified. Although Dr. Bohn concluded that Owens was not “psychotic”, he admitted that Owens “shows some evidence of disturbance”.
At the end of trial, the district court agreed to give an instruction on expert witness testimony. Nevertheless, the court declined to instruct the jury on insanity; instead, the court gave an instruction on the elements of “possession” and “consciousness.” Owens was found guilty and was sentenced to a term of fifteen years imprisonment.
JURY INSTRUCTION ON INSANITY
In the Insanity Defense Reform Act of 1984, Congress defined the insanity defense as follows:
(a) Affirmative defense.—It is an affirmative defense to a prosecution under any Federal statute that, at the time of the commission of the acts constituting the offense, the defendant, as a result of a severe mental disease or defect, was unable to appreciate the nature and quality or the wrongfulness of his acts. Mental disease or defect does not otherwise constitute a defense.
(b) Burden of proof.—The defendant has the burden of proving the defense of insanity by clear and convincing evidence.
18 U.S.C. sec. 17.
Owens attempted to present an insanity defense to the federal offense of gun possession; but the jury received no instruction on insanity. Although the district judge recognized that conscious possession of a gun was essential for guilt, 5 he seemingly doubted that insanity could constitute an affirmative defense to possession of a firearm. The district court also stated that the evidence would not “justif[y] a charge on the defense of insanity”.
Section 17 of Title 18, states that insanity is a “defense to a prosecution under any Federal statute_” 18 U.S.C. sec. 17(a) (emphasis added). Nothing in 18 U.S.C.App. sec. 1202(a) says that insanity is no defense. Therefore, we conclude that insanity can be an affirmative defense to a prosecution for possession of a gun.
Traditionally, in this Circuit, a defendant who requested an instruction on insanity was entitled to it “if there [was] some evidence supporting the claim of insani-ty_ This means only slight evidence.”
Blake v. United States,
*435
The change in the burden of proof necessarily altered our standard for determining whether there is sufficient evidence to require an instruction on insanity. Under
Blake
and its progeny, the “slight evidence” rule was inextricably intertwined with the Government’s burden of proof. As long as there was “some evidence supporting the claim of insanity”, the Government had to prove “sanity beyond a reasonable doubt”, and the jury needed to be informed accordingly.
Blake,
The Supreme Court has stressed that “a higher burden of proof should have a corresponding effect on the judge when deciding to send the case to the jury....”
Anderson v. Liberty Lobby, Inc.,
We hold that, where the issue of insanity has otherwise been properly raised, a federal criminal defendant is due a jury instruction on insanity when the evidence would allow a reasonable jury to find that insanity has been shown with convincing clarity. 7 Recalling the jury’s right to determine credibility, to weigh the evidence, and to draw justifiable inferences of fact, the trial judge must construe the evidence most favorably to the defendant. The court also needs to remember that, although the “clear and convincing” stan *436 dard is a fairly high one, “clear and convincing” does not call for the highest levels of proof. 8 If evidence would permit the jury to find to a high probability that defendant was insane, an insanity instruction is required.
In this case sufficient evidence supports the giving of an instruction on insanity. Particularly important, Dr. Cook, Owens’ expert witness, testified that she diagnosed Owens as a “psychotic” who would lose touch with reality. Viewing the evidence in the light most favorable to the defendant, Owens presented enough evidence to require an instruction pursuant to 18 U.S.C. sec. 17.
Accordingly, we VACATE Owens’ judgment of conviction; we REMAND this case for a new trial. 9

. Owens testified that he had been drinking the night that he was arrested. He could not remember the name of the bar where he was arrested; nor could he remember the names of his drinking companions.
. When asked if the police officer said why he arrested Owens, Owens stated, "He said for possession of a gun.” Owens testified that he told the officer that “I didn't have no gun.” On cross-examination, Owens again asserted that he "didn’t have a gun" — that he "didn’t know about it.”
. On appeal, Owens contends that the district court improperly limited the testimony of Dr. Cook to the issue of “consciousness”. Our examination of the Record indicates, however, that Dr. Cook was allowed to testify fully regarding her examination and diagnosis of Owens. To the extent that Owens complains that “[t]he jury was never told whether this expert believed that defendant’s mental disease prevented him from being able to appreciate the nature and quality or the wrongfulness of his acts”, we find no error: Rule 704(b) of the Federal Rules of Evidence prohibits expert witnesses from testifying regarding such “ultimate issues" as "whether the defendant did or did not have the mental state or condition constituting an element of the crime charged or of a defense thereto.”
See United States v. Alexander,
. This change in law can make a difference in the outcome of criminal trials:
Prior to the Act, evidence short of proof of sanity beyond a reasonable doubt would entitle defendant to an acquittal. The Act, by allocating the burden of proof to defendant, results in an acquittal by reason of insanity *435 only if insanity is proven clearly and convincingly.
There is a substantial middle ground or “grey area” between government proof of sanity (beyond a reasonable doubt) and clear and convincing proof of insanity. Prior to the Act, if the evidence raised a reasonable doubt as to defendant’s sanity or showed him to be possibly insane, he should be acquitted. Under the Act, the same state of the evidence, where his sanity is in doubt or he is possibly but not clearly and convincingly insane, i.e. in the same middle ground, he would not be entitled to an acquittal. The Act thus denies a defendant acquittal if he falls in the middle ground or grey area whereas the pre-Act law would require acquittal in such circumstances.
United States v. Kowal,
. Section 4242(b) of Title 18 says that “if the issue of insanity is raised by notice as provided in Rule 12.2 of the Federal Rules of Criminal Procedure, ... the jury shall be instructed to find ... the defendant — (1) guilty; (2) not guilty; or (3) not guilty only by reason of insanity.” We do not understand this statute to be a command — regardless of the lack of an eviden-tiary foundation for the defense — to instruct the jury on the insanity defense and to use a special verdict form just because a Rule 12.2 Notice has been filed. The headline to section 4242(b) is "Special Verdict." This headline, along with our study of the legislative history, tells us that the intended purpose of 4242(b) was not to define fully what constitutes effectively raising the insanity defense, but to demand special verdicts once the court has concluded that the procedural and evidentiary prerequisites for an insanity defense have been met.
. The Supreme Court has described "clear and convincing evidence” as an "intermediate standard” of proof: the "clear and convincing" standard lies somewhere between “proof by a preponderance of the evidence” and "proof beyond a reasonable doubt.”
See Addington v. Texas, 441
U.S. 418,
Arizona has adopted a statute that—like the federal statute, 18 U.S.C. sec. 17(b)—requires a defendant affirmatively to prove the defense of insanity by "clear and convincing evidence."
See
Ariz.Rev.Stat.Ann. sec. 13-502 (1984). In
State v. Renforth,
The defendant in this case was not required to eliminate ambiguity from his proof or to instill certainty in the minds of the jurors. His lesser burden was to persuade the jury that his position on the psychiatric issue was highly probable....
In summary, a party who has the burden of proof by clear and convincing evidence must persuade the jury that his or her claim is highly probable. This standard is more exacting than the standard of preponderance of the evidence, but less exacting than the standard of proof beyond a reasonable doubt.
Id.
. Owens has raised other issues in this appeal. He argues that (1) the police officer who searched Owens and discovered the pistol violated Owens' Fourth Amendment rights; (2) there was insufficient proof at trial to show that the pertinent pistol travelled in interstate commerce; and (3) due to an alleged deficiency in the indictment, Owens was improperly sentenced to a mandatory minimum term of fifteen years imprisonment under 18 U.S.C.App. sec. 1202(a). These arguments are unpersuasive.
