Thеse consolidated appeals follow the convictions and sentences of a well-known recidivist tax protestor, Irwin Schiff, and two of his acolytes, Cynthia Neun and Lawrence Cohen. After Schiffs last release from prison in 1991 for income tax evasion, he opened a store in Las Vegas, Nevada, where he sold books, audio tapes, videos and instructional packages, many created by him, explaining how to “legally stop paying income taxes.” 1 Cohen and Neun worked at the store, and, together with Schiff, they provided “consultation services” to clients who wished to avoid paying federal income taxes. They encouraged their clients to file “zero returns,” federal individual income tax returns cоntaining a zero on every line related to income and expenses, and, in most cases, seeking an improper refund of all federal income taxes withheld during the tax year for which it was filed.
*1117 Following a twenty-three day joint trial in which Schiff represented himself, the jury returned guilty verdicts with respect to many of the counts in the indictment. In particular, Cohen was convicted of one count of aiding and assisting in the filing of a false federal income tax return in violation of 26 U.S.C. § 7206(2), for which he received a thirty-three month sentence. 2 At trial, the district court summarily convicted Schiff of fifteen counts of criminal contempt pursuant to 18 U.S.C. § 401 3 based on his unruly courtroom behavior. Schiffs total sentence for those convictions was twelve months in prisоn to be served consecutively to his tax evasion and conspiracy sentence.
Cohen argues that his conviction must be overturned because the district court wrongfully excluded the expert testimony of his psychiatrist who would have offered evidence of Cohen’s mental state. We agree, and we reverse Cohen’s conviction, vacate his sentence, and remand for a new trial.
Schiff challenges the contempt convictions and the resulting sentences. We vacate the contempt convictions due to the district court’s failure to properly file contempt orders for each of those convictions as required by Federal Rule of Criminal Procedure 42(b) and our precedent. We remand to allow the district court to file those orders in proper form, to then reinstate the contempt convictions and reimpose punishment for Schiffs contumacious behavior.
I
A
Schiffs convictions for criminal contempt arose primarily from his refusal to heed repeated warnings by the trial judge to cease arguing to the jury his erroneous views of the law. Schiff often instructed witnesses to read passages from his books explaining his characterization of the voluntary nature of the federal income tax. For example, one witness read, “There is no question that it is ... all correct. Paying and filing income tax[] are, by law, voluntary.” Schiff frequently couched misstatements of the law in questions to witnesses. For example, Schiff asked one witness, “Were you aware that none of those sections [of the Internal Revenue Code] said you ... were required to file a tax return?” On another occasion, Schiff asked a witness whether she was aware that “there’s no provision in the law that allows the IRS to put on liens[.]” Schiff also asked a witness whether a passage from one of Schiffs books “tr[ies] to estab *1118 lish the fact that income in the ordinary sense is not exactly income in the tax sense.” Schiffs defiance also took the form of his persistent refusal to cease particular lines of questioning after the district judge had previously ruled them improper and misleading.
During the first eight days of trial, the district judge dealt with Schiffs misconduct by sustaining the government’s objections and sometimes explaining to Schiff the legal basis for doing so. Schiff nonetheless persisted. On the ninth day of trial, following yet another transgression, the district judge warned Schiff at a sidebar conference that if his insolence continued, he would risk a contempt citation and sanctions.
Schiff still did not heed the warnings. The next day, Schiff suggested to the jury during his questioning of a witness that the law does not prohibit the concealment of one’s assets from the government. He also improperly suggested that the government lacked the power to investigate criminal violations of the Internal Revenue Code. He continued to ask similar questions even after two objections by the government were properly sustained.
At that point, the understandably exasperated district judge summarily held Schiff in criminal contempt and sentenced him to one day in jail, “deferred until the conclusion of this trial. The next time it will double and it will continue to double until you ... respect the rulings of the Court.” Despite fair warning as to the consequences of persisting in this manner, Schiffs contumacious behavior continued, and he was thereafter sanctioned fourteen more times during the trial. On each of these occasions, the district judge simply stated “sanctions” so as not to “let the sanctions overly influence the jury.”
At Schiffs post-trial sentencing hearing, the district judge reduced the sentence for ten of the fifteen sanctions to one month each:
So, on the first sanction, it was one day; on the seсond sanction, it was two days; on the third, four days; on the fourth, eight days; on the fifth, sixteen days for a total of approximately one month cumulatively as of sanction number five. Thereafter, what I have decided to do is impose one month for each successive sanction resulting in a total of twelve months as the sentence for contempt citations during trial. 4
The district court briefly explained on the record its reasons for remitting this sentence, but did not file contempt orders for any of the convictions. Schiff was not afforded the opportunity to address the court with respect to his contempt convictions. Nor does it appear from the record that the court notified Schiff in advance of the sentencing hearing that his contempt convictions would be addressed.
B
Schiff raises three challenges to his contempt convictions and sentence. First, he argues that the district court erred by failing to file contempt orders as required by Federal Rule of Criminal Procedure 42(b). Second, he asserts that the sentence violates his right to due process under the Fifth Amendment because he did not receive notice or an opportunity to be heard at the post-trial sentencing hearing. Third, he maintains that the sentence violated his Sixth Amendment right to a trial *1119 by jury because his sentence exceeded six months. We address each of these arguments in turn.
1
We review summary contempt convictions for abuse of discretion.
United States v. Flynt,
Here, the district court did not file the requisite contempt orders. The government argues that we should excuse the oversight because the district court “made the reasons for the sanctions abundantly clear on the record.” The government relies on
United States v. Marshall,
The government is mistaken. Our case law establishes that the district judge must file a contempt order setting forth in detail the factual basis of the contempt conviction and certifying that the district judge personally witnessed the conduct giving rise to the conviction.
See id.
at 374-75 (emphasizing that contempt orders are “ ‘more than a formality,’ ” and finding the contempt orders at issue insufficient because they contained “[c]onclusory language and general citations to the record”);
see, e.g., In re Contempt of Green-berg,
We see no choice under our precedent interpreting Rule 42(b) but to vacate Schiffs criminal contempt convictions and remand to allow the district court to comply with the rule. In doing so, we understand the difficulty posed by an irascible
pro se
defendant like Schiff who presents himself in such a challenging manner to a trial judge who is earnestly attempting to maintain a fair and impartial trial through order and decorum in the courtroom. We remand to the district court to allow it to file the requisite fifteen contempt orders.
See Marshall,
2
Next, we address Schiffs argument that his sentences for the contempt convictions were imposed in violation of his Fifth Amendment right to due process and Sixth Amendment right to a jury trial. The contours of Schiffs argument are less than clear. He seems to be arguing that, in effect, he was not summarily convicted and punished for criminal contempt fifteen times during trial, but rather, was cited fifteen times during trial and, at the post-trial sentencing hearing, was given a single sentence exceeding six months.
In Schiffs view, where a person is cited for criminal contempt during trial but punished after, that person is entitled under the Fifth Amendment’s Due Process Clause to notice and an opportunity to be heard at the sentencing hearing. Schiff also contends that where a person is given a single punishment for multiple acts of contempt, that person is entitled under the Sixth Amendment to a jury trial if the punishment exceeds six months. We do not disagree with those general legal propositions.
See Taylor v. Hayes,
However, we reject Schiffs premise based on his contention that he was cited during trial for contempt but convicted and sentenced after. The district court summarily convicted and sentenced Schiff at the time each of the fifteen separate contumacious acts occurred. The record clearly shows that Schiff was informed in advance of the progressive punishment that would be imposed for each repeated act in contempt of the district court’s mid-trial rulings committed in the presence of the court and the jury. He was not entitled to relitigate his misbehavior after the trial because each mid-trial contempt conviction and sentence became final at the time the contemptuous conduct occurred, and he was summarily sanctioned for it as the district judge tried as best he could to maintain order and coerce Schiff into complying with his rulings.
Schiff relies primarily on
Taylor v. Hayes,
The Court began its analysis by noting that the case before it did not involve the trial judge’s exercise of his summary contempt power.
Id.
at 497,
[N]o sentence was imposed during the trial, and it does not appear to us that any final adjudication of contempt was entered until after the verdict was returned. It was then that the [trial judge] proceeded to describe and characterize petitioner’s various acts during trial as contemptuous, to find him guilty of nine acts of contempt, and to sentence him immediately for each of those acts.
Id.
The Court devotes the remainder of its opinion to explaining why, in the context of a non-summary contempt conviction, the contemnor is entitled to “reasonable notice of the specific chаrges and opportunity to be heard in his own behalf.”
Id.
at 499,
Unlike the trial court in Taylor, the district court convicted and punished Schiff immediately as each act of contempt occurred. During the first eight days of trial, the district court warned Schiff innumerable times to obey court orders. On the ninth day, after Schiff continued to disregard the court’s admonishments, the court explicitly held Schiff in criminal contempt and punished him immediately by imposing one day of incarceration. We have no difficulty concluding that this constituted a final adjudication and punishment for the first contumacious act that occurred in the court’s presence.
The closer question is whether the district court’s simple utterance of the word “sanction” after each of the subsequent fourteen contumacious acts in an apparent attempt to prevent Schiff s contemptuous behavior from distracting the jury, constitutes a final adjudication and sentencing. We hold that it does. At the time of the first contempt conviction, the district court expressly provided Schiff with a formula for determining the punishment that would attach to further acts of contempt. Under that formula, he was fairly warned that the sentence imposed for each successive contumacious act doubled. The district court also informed Schiff at the time of the first contemptuous act that rather than bring the proceedings to a halt each time Schiff engaged in contempt of the court’s rulings, the district court would simply state “sanctions.” That word thus had a two-fold meaning: first, it meant that Schiff was being held in criminal contempt; second, it provided, based on the punitive formula previously announced, the specific punishment for each act of contempt. We see nothing wrong with a district court employing such progressive punishment and providing fair warning in advance to the contemnor in order to curb persistent misconduct and maintain order in the proceedings.
When the district court stated “sanctions,” that word did not denote simply a citation whose implications would be discussed after trial in conjunction with other contempt citations. Rather, the district court treated each instance of contemptuous conduct as a “discrete and separate matter,”
Codispoti,
Our conclusion is not altered by the fact that after the trial, the district court chose to reduce the respective punishments for ten of the contempt convictions to one month each. The function of that hearing was not to determine whether Schiff should be held in criminal contempt, and if so, to impose a sentence. Schiff had already been convicted and sentenced on fifteen separate occasions. Rather, the function of that hearing was to sentence Schiff for the guilty verdicts that the jury had returned on the tax and conspiracy counts charged in the indictment, to add up the fifteen contempt sentences Schiff had already received, and to determine whether the sentences should run concurrently or consecutively. The district court’s discretionary decision to remit the punishments for some of those later mid-trial contempt convictions does not, in our view, bring this case into line with those such as
Taylor
and
Codispoti,
where the contemnor was citеd during the trial, and the final decision of whether to hold him in criminal contempt, and if so, the punishment to be imposed for that crime, was deferred until the trial’s conclusion. The concerns expressed in
Taylor
and its progeny about the “heightened potential for abuse posed by contempt power,”
Taylor,
In sum, we conclude that Schiff was summarily cited and contemporaneously sentenced fifteen separate times during the trial for criminal contempt. As a result, he was not entitled under the Fifth Amendment’s Due Process Clause to additional notice or an opportunity to be heard with respect to contesting those convictions or the summary punishments imposed at the post-trial sentencing hearing.
See Taylor,

A
The more troublesome issue we address concerns the district court’s handling of proffered expert psychiatric evidence on behalf of appellant Cohen in the face of our precedent. On June 14, 2005, Cohen’s lawyer filed a notice, pursuant to Federal Rule of Criminal Procedure 12.2, that he intended to offer expert testimony by psychiatrist Dr. Norton A. Roitman relating to Cohen’s “mental disease ... bearing on ... the issue of guilt.” Attached to that notice was a report prepared by Dr. Roit-man, who had met with Cohen on two occasions at the request of Cohen’s attorney.
In the report, Dr. Roitman diagnoses Cohen as suffering from a narcissistic per *1123 sonality disorder, and concludes that Cohen “did not intend to violate the law, as would be the case with a criminal who acted out of a desire for personal gain” but rather “[h]is behavior is driven by a mental disorder as opposed to criminal motivation ... Althоugh it is true Mr. Cohen was not delusional or psychotic and was in possession of basic mental faculties, his will was in the service of irrational beliefs as a result of narcissistic personality disorder.” The report also notes that
Because [Cohen’s] beliefs are fixed and have led him to significant adverse consequences, he is irrational to the point of dysfunction, demonstrated by his stubborn adherence in the face of overwhelming contradictions and knowledge of substantial penalty. ... Despite evidence to the contrary, his psychological needs dominated his mentation.... This is the nature of the narcissistic personality in which the sufferer could essentially pass a lie detector test when asked commonsensical questions while giving improbable answers.
The government moved to bar Dr. Roit-man from testifying and the district court agreed, reasoning that Dr. Roitman failed to explain “how the alleged mental disorders negate mens rea. Rather, [his] opinion[ ] merely explain[s] or justifies] [Cohen’s] conduct.”
B
“We review for abuse of discretion a district court’s decision to admit or exclude scientific evidence.”
United States v. Finley,
C
Federal Rules of Evidence 702 and 704(b) govern the admissibility of Dr. Roit-man’s testimony, and we examine the exclusion of his testimony under both of these rules.
5
See, e.g., Finley,
1
The threshold issue is whether Dr. Roitman’s testimony would have assisted the trier of fact within the meaning of Rule 702. According to Cohen, Dr. Roitman’s testimony would have bolstered the contention that Cohen had a good faith belief that he was acting in accordance with the law, thereby negating the
mens rea
element of 26 U.S.C. § 7206(2), which requires that a defendant “[w]illfully”
6
assist
*1124
in the filing of a false return.
See Cheek v. United States,
that defendant was not capable of forming the requisite mens rea for the charged offenses. On the contrary, as the District Court found, Dr. Roitman’s report did no more than explain why defendant intentionally violated his known legal duties. The report does not remotely suggest that defendant lacked the mental aptitude to understand his legal duties or the ability to act volition-ally.
Cohen argues that
United States v. Finley,
We reversed, reasoning that the excluded testimony
would have offered an explanation as to how an otherwise normal man could believe that these financial instruments were valid and reject all evidence to the contrary. While Finley could and did tеstify about how and why he believed the instruments were valid, only a trained mental health expert could provide a counterweight to the government’s allegations against Finley.
Id. at 1013.
The facts in Finley are strikingly similar to those in the present case. Schweitzer convinced Finley that certain financial instruments were genuine; Schiff convinced Cohen that one could legally submit a zero return. Expert testimony proffered by Finley and Cohen suggested they had a tendency to cling doggedly to their beliefs even in the face of overwhelming contradictions. The Finley court determined that the expert testimony could have helped the defendant counter the government’s argument that he knew the financial instruments were false; similarly, Dr. Roitman’s testimony would have helped Cohen counter the government’s suggestion that Cohen knew the zero returns were false.
We disagree with the government that Dr. Roitman’s report can only be read to mean that Cohen knew what he was doing was wrong but did it anyway. In fact, the opposite is true: a fair reading of Dr. Roitman’s report suggests that once Cohen adopted Schiffs views, Cohen would not change his mind. The report specifically states that Cohen “did not intend to violate the law.” If Dr. Roitman had been allowed to testify to that effect, his testimony would have assisted the trier of fact within the meaning of Rule 702.
*1125
The government’s reliance on
United States v. Scholl,
Scholl is easily distinguishable from the present case. According to his expert’s report, a narcissistic personality disorder like Cohen’s can cause a person to continue to believe something to be true despite overwhelming evidence оf its patent absurdity. By contrast, there was no evidence in Scholl that an addiction to gambling could cause a person to believe that a false tax return omitting winnings was true.
Neither
United States v. Byers,
2
Rule 704(b) is a limitation on Rule 702. Even if expert testimony would “assist the trier of fact” within the meaning of Rule 702, such testimony may be excluded under Rule 704(b) if the testimony “state[s] an opinion or inference as to whether the defendant did or did not have the mental state or condition constituting an element of the crime charged.... ” Fed.R.Evid. 704(b). With respect to the type of inference precluded under Rule 704(b), the court has stated that the expert may not “draw[ ] an inference which would necessarily compel the conclusion” that the defendаnt lacked the requisite
mens rea. Morales,
United States v. Morales,
In Finley, we concluded that the psychologist’s testimony did not violate Rule 704(b) because
The jury could have accepted the atypical belief diagnosis and still concluded that Finley knowingly defrauded the banks. If credited, [the expert’s] testimony established only that Finley’s beliefs were rigid and he would distort or disregard information that ran counter to those beliefs. [The expert] did not, and would not be allowed to, testify about Finley’s specific beliefs with regard to the [bogus] financial instruments. The jury was free to conclude that Finley knew the notes were fraudulent, despite the rigidity of his belief system.
We have little doubt that if Dr. Roitman had been permitted to testify as to all of the conclusions contained in his report, some of that proffered testimony as contained in his report would have invaded the province of the jury and violated Rule 704(b). However, the best way for the district court to have insured the exclusion of the potentially inadmissible aspects of Dr. Roitman’s testimony was not to bar him from testifying altogether, but to sustain the government’s objections to particular questions likely to elicit inadmissible evidence undеr the rule. The district court also could have discussed with the parties before he testified the limits that would be imposed on the scope of Dr. Roitman’s testimony.
See Finley,
If the district court had followed that course of action, then Dr. Roitman’s testimony, like the expert testimony at issue in Morales and Finley, would have gone to a predicate matter — whether Cohen suffered from a Narcissistic Personality Disorder. Even if the jury had accepted this diagnosis, the jury would still have been required to determine what impact, if any, that condition might have on Cohen’s ability to form the requisite mens rea — the intent to evade the tax laws. As in Finley, the jury could have accepted the Roitman diagnosis but determined nonetheless that Cohen knew the zero returns were false.
The government relies on
United States v. Campos,
Campos is easily distinguishable. If Dr. Roitman’s testimony was limited in the manner described above, the jury could still have concluded that Cohen knew the zero returns were false but chose nevertheless to assist others in filing them. But in Campos, if the jury believed the polygraph expert, the conclusion that the defendant lacked the requisite mens rea was inescapable.
3
The government argues that even if Dr. Roitman’s testimony was admissible under Rules 702 and 704(b), it should have been excluded under Rule 403. 7 We dis *1127 agree. Dr. Roitman’s testimony would have been highly probative on the issue of whether Cohen could have formed the requisite mens rea, and was unlikely to cause significant confusion with the jury if properly constrained by compliance with the rules of evidence.
4
“Under our test for nonconstitutional error, which we apply to errors as to the admissibility of expert testimony, we must reverse unless it is more probable than not that the error did not materially affect the verdict.”
United States v. Rahm,
The court in
Finley
concluded that the exclusion of the expert’s testimony was not harmless because that testimony was “essential to the defense.”
III
SchifPs criminal contempt convictions are vacated, and the case is remandеd to allow the district court to file the requisite contempt orders pursuant to Federal Rule of Criminal Procedure 42(b). Any sentence reimposed must not exceed eleven months. The district court retains the discretion to impose the contempt punishment to run consecutively to the sentence for the tax convictions. Cohen’s conviction is reversed, his sentence vacated, and the case is remanded for a new trial. The remaining issues are addressed in the accompanying memorandum disposition.
AFFIRMED in part, REVERSED in part, and REMANDED.
Notes
. In
United States v. Schiff,
. Schiff was convicted of cоnspiracy to defraud the government for the purpose of impeding and impairing the Internal Revenue Service in violation of 18 U.S.C. § 371 (also known as a
“Klein
conspiracy”;
see United States
v.
Klein,
. 18 U.S.C. § 401 states, in relevant part, "A court of the United States shall have power to punish by fine or imprisonment, or both, at its discretion, such contempt of its authority, and none other, as — (1) Misbehavior of any person in its presence or so near thereto as to obstruct the administration of justice....”
. The district court made a mathematical error in calculating Schiffs punishment for criminal contempt. If the combined punishment for the first five contempt convictions totals thirty one days (1 + 2 + 4 + 8 + 16 = 31), and the punishment for the remaining ten convictions are each one month, then the total punishment is eleven months, not twelve. We will discuss the implications of this error below.
. Rule 702 provides, "If scientific ... knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert ... may testify thereto in the form of an opinion or otherwise.” Rule 704(b) prohibits the expert from offering “an opinion or inference as to 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.”
. "Willfulness requires that an act be done knowingly and intentionally, not through ignorance, mistake or accident.”
Morales,
. Federal Rule of Evidence 403 provides that relevant evidence may be excluded “if its pro *1127 bative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury...."
