Defendant-appellant Charles Dewire pled guilty to using a means of interstate commerce to induce a minor to engage in a sexual act, in violation of 18 U.S.C. § 2422(b). Dewire thereafter moved for a downward departure on grounds of aberrant behavior. The district court refused to depart and imposed a sentence of one year and a day, the minimum authorized by the Sentencing Guidelines. Dewire appeals, arguing: (1) that the district court’s refusal to depart was based on an erroneous factual finding that he had downloaded child pornography from the Internet; and (2) that the district court abused its discretion by denying a continuance to permit him to gather evidence to show that he had not solicited the pornographic images that had been mailed to his Internet account. We hold that the denial of a motion for a departure based on an alleged mistake of fact does not present an appealable issue. Accordingly, we lack jurisdiction to hear this appeal, and we therefore affirm the district court.
1. BACKGROUND
Using America Online (“AOL”) Instant Messenger, 1 Dewire engaged in a sexually explicit conversation with an individual whom he believed to be a twelve year-old girl. Toward the end of the conversation, he arranged to meet the girl the following afternoon at a local restaurant. In reality, the “girl” was an adult swim team coach, working on the family computer while visiting the girl’s home. The coach printed the exchange with Dewire and turned it over to law enforcement authorities. De-wire was observed the next day entering and leaving the restaurant. Confronted later at his home by FBI agents, Dewire confessed.
After his indictment, Dewire filed a motion to dismiss. With its opposition to the motion, the government submitted a sealed exhibit containing images of children in graphic sexual poses, in many cases with adults. These images had been sent as e-mail attachments on three occasions between 1996 and 1998 to screen names listed to Dewire’s AOL account. The district court denied Dewire’s motion to dismiss, and the guilty plea followed. The Sentencing Guidelines, after an adjustment for acceptance of responsibility, prescribed a Category I offense level of 13, with a resulting sentencing range of twelve to eighteen months. Dewire moved for a downward departure claiming aberrant behavior.
See United States v. Grandmaison,
At the sentencing hearing, Judge Wolf expressed concern about the instances of child pornography being sent to Dewire’s e-mail account. He asked, “[w]eren’t all of those events or some of those events possibly a crime?” He further questioned whether Dewire had been fully candid with his doctors about his previous involvement with child pornography. He also inquired whether, given the prior receipt of pornographic images of children, Dewire’s conduct could fairly be characterized as aberrant. “I wonder whether this is properly a single act of -aberrant behavior.... [I]f he committed, even though he was not convicted or even charged with, other crimes, I wonder if I could fairly and properly call this a single act of aberrant behavior.” Commenting further, Judge Wolf said,
I am not persuaded that the crime here was a single act of aberrant behavior. The defendant received child pornography from the Internet on at least three occasions from 1996 to 1998....
He downloaded these materials himself at least one time. Then he said he didn’t recall, when he was initially interviewed by the FBI, downloading the others. Knowing receipt of such materials is a crime but not part of this offense.
In response to Judge Wolfs comments, Dewire’s counsel moved for a continuance for the stated purpose of exploring the possibility that Dewire had received the images as unsolicited e-mail attachments. Judge Wolf denied the motion to continue and imposed a committed sentence of one year and one day, to be followed by three years of supervised release.
In denying the continuance, Judge Wolf stated that despite his concerns about the images and Dewire’s apparent lack of candor, these were not determinative factors in his sentencing decision. “In my estimation, the only question was what were the circumstances of the downloading. And I think ... while that is relevant, it is not what is at the heart of this matter.” Judge Wolf further stated that were the images the “sole” or “dominant” factor in his decision, he would have granted a continuance to “clarify the record.” “[I]f this, in my estimation, were pivotal, decisive, I might have allowed the request but not in these circumstances.” In explaining his sentence, Judge Wolf stated that,
perhaps decisively, in this instance, the nature and seriousness of the offense does not justify a sentence of probation, even if this were an isolated aberrant act.
... And I find in this case it is appropriate in part to deter others who might be tempted to use the Internet to pray [sic] upon children and to recognize the seriousness of the offense.
Following the hearing, Dewire moved to stay the sentence pending appeal. At the hearing on the stay motion, Judge Wolf *337 commented again on his reasons for denying a downward departure, explaining “while there was a lot of discussion about the images, they were not material to the outcome of the case.” He repeated his observation that even if Dewire’s conduct had been aberrant, he did not believe that a departure was warranted because of the extremely serious nature of the offense. He added that a continuance “would not have been useful” because he “would have given the same sentence anyway.” He did, however, grant the stay.
II. DISCUSSION
The issue that we are asked to decide is whether a district court’s refusal to depart is appealable when it is based on an allegedly erroneous mistake of fact. 3 We answer the question “no” on the basis of well-established precedent in this Circuit.
Where a refusal to depart is appealable, a trial court’s decision is reviewed against an abuse of discretion standard.
See Koon v. United States,
To be sure, this Court has never squarely addressed the issue before us. 4 In Pietro, however, while acknowledging a degree of confusion regarding the application of the rule and its exceptions, we were emphatic that in the context of departures, the touchstone of appealability is a mistake of law. As we explained,
[i]f the judge sets differential factfinding and evaluative judgments to one side, and says, in effect, “this circumstance of which you speak, even if it exists, does not constitute a legally sufficient basis for departure,” then the correctness of that quintessentially legal determination may be tested on appeal. But if the judge says, in effect, either that “this circumstance of which you speak has not been shown to exist in this case,” or, alternatively, that “while this circumstance of which you speak might exist and might constitute a legally cognizable basis for a departure in a theoretical sense, it does not render this particular case sufficiently unusual to warrant departing,” then, in either such event, no appeal lies.
Since
Pietro,
we have consistently adhered to the position that “a refusal to depart is unreviewable unless the district court based [its decision] on an error of
*338
law.”
United States v. Santos,
Dewire argues that notwithstanding
Piern
and a phalanx of contrary First Circuit precedent, this Court should adopt the reasoning of the Court of Appeals for the District of Columbia Circuit in
United States v. Sammoury,
[c]learly erroneous factual determinations used in determining adjustments ... may lead to a sentence imposed as a result of an incorrect application of the Guidelines, even though the judge thoroughly understood the pertinent guideline. ... The same may be said of clearly erroneous factual mistakes used in determining whether to depart.... It is no more an infringement on the discretion of trial judges to set aside a sentence when the refusal to depart rests on a clearly erroneous factual mistake than to set aside a sentence when the refusal stems from a misinterpretation of the Guidelines.
Sammoury,
The result is, of course, different if a factual mistake, say a miscalculation of the drug quantity to be attributed to a defendant, results in an improper Guideline application. This is the instance, in our view, to which section 3742(e)’s admonition that a district court’s findings of fact are to be accepted unless “clearly erroneous,” is directed.
See United States v. Cali,
The precedents to which we adhere in today’s decision rest on sound policy grounds. Because a trial court’s refusal to depart is inherently discretionary and fact-based, a rule contrary to our precedent would invite frivolous appeals, discourage trial judges from explaining a refusal to depart, 7 .and require this court to second- *340 guess, on a cold, and often factually dense record, the subjective influence that a questionable fact may have exerted on a trial judge’s ultimate sentencing decision. 8
III. CONCLUSION
In this case, Dewire does not contend that the district court misapprehended its authority to depart. To the contrary, the record is clear that the trial court understood it had such discretion: “[I] assume that I have the discretion provided by Grandmaison [and] its progeny to allow the motion for downward departure.” Instead, the district court stated that it did not believe that Dewire satisfied the Grandmaison criteria. The district court noted that: (1) in light of Dewire’s receipt of child pornography on three previous occasions, it was not convinced that the offense was an aberrant act; (2) because Dewire had not been fully candid with his doctors about the details of the offense and his past history, it had discounted their opinions as to the risk of recidivism; and (3) the crime itself was not spontaneous or thoughtless. Moreover, the district court stated that even if De-wire had qualified on the facts for a downward departure, it would as a discretionary matter decline to depart because it felt that a prison sentence was necessary to vindicate the goals of specific and general deterrence and to appropriately recognize the seriousness of the offense.
Given that the district court did not misunderstand its authority to depart and therefore made no mistake of law, we hold that we lack jurisdiction to entertain this appeal. Consequently, we need not address the appellant’s other arguments. 9

. Section 5K2.20, an amendment to the Sentencing Guidelines addressing departures *336 based on aberrant behavior, went into effect on November 1, 2000. Prior to this amendment, Grandmaison established the parameters for such departures in the First Circuit. The parties and the district court agreed that Grandmaison, and not the new amendment, governed Dewire's case because his offense occurred prior to section 5K2.20’s enactment. We accept the soundness of this conclusion.
Dewire also argued that the circumstances of his offense lay outside the "heartland” of the typical offense of its kind, thus justifying a departure pursuant to U.S.S.G. § 5K2.0. De-wire does not pursue this argument on appeal.
. While the parties have appropriately framed the issue in terms of a district court’s refusal to depart downward, our reasoning would apply equally to a district court’s denial of a motion by the government to depart upward.
. In
United States v. O'Connell,
. Our view is shared by the Fourth, Eleventh, and Seventh Circuits, which have also declined to hear appeals of fact-based denials of downward departures.
See United States v. Underwood,
. Several other Circuits have appeared at times to have aligned themselves with the District of Columbia Circuit. The Ninth Circuit has reviewed a district court’s factual findings for clear error where the denial of a downward departure was in the court's discretion.
United States v. Roe,
. As Judge Wolf noted in the hearing on the motion for a stay of execution of sentence, "it’s clear that if I had just said, denied, and not had a lengthy hearing or given any reasons, this would not be an appealable issue. But I'm not trying to avert an appeal. If I made a mistake, I don't want [the defendant] to be injured by it.” As we observed in
United States v. Tucker,
. An example may illuminate this point. Suppose a trial court provides three fact-based reasons for refusing to depart. A defendant then shows that one of the court's reasons was based on a mistaken factual assumption. An appeals court would then have to consider whether either of the other two stated reasons would have been sufficient to justify the trial court's decision, and moreover, the degree to which one or the other of the factually correct premises influenced the judge’s thinking. This exercise would essentially vitiate the broad discretion granted to trial judges in matters of sentencing. Alternatively, if the appeals court were to remand such cases to the trial courts, the interests of judicial economy and finality would be compromised, without any likely change in the outcome of the vast majority of cases. This is not to say that we cannot envision a case where a trial judge's factual mistake was so egregious as to require intervention by an appeals court — say the trial judge mistook the defendant for someone else — although we are of the view that the issue raised by a mistake on this order would be one of due process and not sentencing error.
See United States v. McDavid,
. If, however, we were to consider this appeal on the principal ground urged by appellant (factual mistake), we would conclude that the record clearly shows that the district court's decision to deny a departure was ultimately based not on the alleged downloading of the child pornography, but on other considerations concerning the nature of the crime.
