The rule in one paragraph
If a criminal statute requires that a defendant act "knowingly," can someone escape liability by making sure he never quite finds out? United States v. Jewell, 532 F.2d 697 (9th Cir. 1976) (en banc), said no. A driver who strongly suspected drugs were hidden in his car, and deliberately avoided looking, could be found to have known. The court's core sentence: "The substantive justification for the rule is that deliberate ignorance and positive knowledge are equally culpable." This doctrine is usually called willful blindness (or deliberate ignorance), and Jewell is the case that made it a standard jury instruction. For mental states generally, see our mens rea and actus reus guide.

| Majority | Judge Browning, for the en banc court |
| Dissent | Then-Judge Anthony M. Kennedy, joined by Judges Ely, Hufstedler, and Wallace |
| Result | Convictions affirmed |
| Rule | Knowledge includes acting "with an awareness of the high probability of the existence of the fact in question." Deliberately avoiding confirmation does not defeat knowledge. |
Key terms before you read the case
| Term | What it means here |
|---|---|
| Knowledge | Awareness that a fact exists. Under MPC § 2.02(7), awareness of a high probability can be enough. |
| Willful blindness / deliberate ignorance | Suspecting a fact is very likely true and deliberately avoiding confirmation. Treated as knowledge when both parts are proven. |
| Recklessness | Consciously disregarding a substantial and unjustified risk. Not enough when a statute requires knowledge. |
| Negligence | Failing to perceive a risk a reasonable person would have noticed. Never enough for knowledge. |
| Deliberate ignorance instruction | A jury instruction (often called a Jewell instruction) explaining when avoiding the truth can satisfy a knowledge element. |
The instruction the jury heard
Jewell was charged with knowingly importing a controlled substance (21 U.S.C. §§ 952(a), 960(a)(1)) and knowingly possessing it with intent to distribute (21 U.S.C. § 841(a)(1)). Over a defense objection, the trial judge instructed:
"The Government can complete their burden of proof by proving, beyond a reasonable doubt, that if the defendant was not actually aware that there was marijuana in the vehicle he was driving when he entered the United States his ignorance in that regard was solely and entirely a result of his having made a conscious purpose to disregard the nature of that which was in the vehicle, with a conscious purpose to avoid learning the truth."
Jewell was convicted. The Ninth Circuit heard the case en banc, explaining that it did so partly "to perform a simple but necessary "housekeeping" chore": an earlier opinion had loosely called drug possession a "general intent" crime, and the court wanted to clarify what the knowledge element actually requires.
Holding and reasoning
The court affirmed. Its definition of knowledge became the most-cited part of the opinion: to act knowingly is "to act with an awareness of the high probability of the existence of the fact in question. When such awareness is present, 'positive' knowledge is not required."
Model Penal Code § 2.02(7)
When knowledge of a fact is an element of an offense, "such knowledge is established if a person is aware of a high probability of its existence, unless he actually believes that it does not exist."
Applied here, "the jury would have been justified in accepting all of the testimony as true and concluding that although appellant was aware of facts making it virtually certain that the secret compartment concealed marihuana, he deliberately refrained from acquiring positive knowledge of the fact." The majority also stressed the doctrine's limits, quoting the principle that "A court can properly find wilful blindness only where it can almost be said that the defendant actually knew." It acknowledged the instruction was not ideal but found no reversible error.
The Kennedy dissent
Then-Judge Kennedy, joined by Judges Ely, Hufstedler, and Wallace, accepted the Model Penal Code approach but said this instruction didn't follow it. The MPC provision "requires an awareness of a high probability that a fact exists, not merely a reckless disregard, or a suspicion followed by a failure to make further inquiry."
The dissent identified two gaps. The instruction never required the jury to find that Jewell was aware of a high probability that drugs were in the car, and it never told the jury to acquit if he actually believed there were none. The danger, in the dissent's words, was that the instruction might "permit the jury to convict on an "objective" rather than "subjective" theory of the knowledge requirement." Its core principle: "true ignorance, no matter how unreasonable, cannot provide a basis for criminal liability when the statute requires knowledge."
The dissent lost the vote, but its insistence on a real finding of high-probability awareness is now built into modern deliberate ignorance instructions and into the Supreme Court's Global-Tech test.
What later courts did with Jewell
| Source | Awareness required | Avoidance required |
|---|---|---|
| Jewell majority (1976) | Awareness of a high probability | Conscious purpose to avoid learning the truth |
| Jewell dissent (1976) | Awareness of a high probability, stated in the instruction | Plus: acquit if the defendant actually believed otherwise |
| MPC § 2.02(7) | Aware of a high probability | No separate avoidance element; actual belief otherwise defeats knowledge |
| Heredia / 9th Cir. Instr. 4.9 | Aware of a high probability | Deliberately avoided learning the truth |
| Global-Tech (2011) | Subjectively believes a high probability | Deliberate actions to avoid learning the fact |
How Jewell shows up on exams
Look for a defendant who says "I didn't know" in a crime that requires knowledge: a courier with a sealed package, a buyer of suspiciously cheap goods, an employee who never reads the invoices. The professor wants you to decide whether this is knowledge, recklessness, or negligence.
On homicide questions, the same mental-state ladder matters for grading; see our guide to felony murder and homicide grading.

Frequently asked questions
What was the holding in United States v. Jewell?
The en banc Ninth Circuit affirmed Jewell's drug convictions. It held that the knowledge element can be satisfied when the defendant is aware of a high probability that a fact exists and deliberately avoids confirming it, because deliberate ignorance and positive knowledge are equally culpable.
Is willful blindness a defense?
No. Willful blindness works against a defendant: it is a way for the prosecution to prove knowledge. A defendant can't avoid a knowledge requirement by deliberately refusing to confirm what he strongly suspects. Genuine ignorance, even if unreasonable, is different and can defeat a knowledge element.
What are the four levels of intent?
Under the Model Penal Code, the four culpable mental states are purpose, knowledge, recklessness, and negligence. Willful blindness counts as knowledge. Recklessness (consciously disregarding a substantial risk) and negligence (failing to perceive a risk a reasonable person would notice) do not satisfy a knowledge requirement.
What is the Model Penal Code definition of willful blindness?
MPC § 2.02(7) provides that when knowledge of a fact is an element of an offense, "such knowledge is established if a person is aware of a high probability of its existence, unless he actually believes that it does not exist." Jewell relied on this provision.
Is the Model Penal Code still used?
The Model Penal Code is a model, not binding law, but many states drew on it when revising their criminal codes, and courts borrow its definitions. Jewell is an example: a federal court relied on MPC § 2.02(7) to define knowledge in federal drug statutes.
What test did Global-Tech v. SEB set for willful blindness?
In Global-Tech Appliances v. SEB (2011), the Supreme Court said the defendant must (1) subjectively believe there is a high probability that a fact exists and (2) take deliberate actions to avoid learning of that fact. It cited Jewell and said these requirements give the doctrine a scope that surpasses recklessness and negligence.
