The Classroom Series · Drafted by the Clerk
Same Facts, Different Bar
This lesson was drafted by the Clerk on request, and the case in it is invented. The parties, the facts and the jurisdiction are fictional, written to argue well rather than to report anything. Nothing here is a real case, and nothing here is legal advice. Read it before you teach it: it has not been through the human review our published cases get.
What this lesson teaches
Reasonable doubt is not a feeling. It is a specific, demanding standard that sits at one end of a spectrum of burdens the law uses depending on what is at stake. Students hear this phrase constantly on television and have almost no working sense of what it actually requires them to do as jurors, or how differently a case comes out when the bar for proof moves. The only way to make that visible is to make them decide the identical case twice, under two different instructions, and watch their own verdicts split.
This lesson uses the instruction mechanism: one record, two burdens. Half the room is told to convict if they believe the defendant more likely than not committed the act. The other half is told to convict only if they have no reasonable doubt. Same facts, same witnesses, same exhibits. The only variable is the instruction. That isolation is the whole point of the doctrine, and no other mechanism gets there as cleanly, because reasonable doubt is not about what evidence comes in, it is about how sure that evidence has to make you.
Before class
- Print one copy of the Case File per student. It is identical for everyone; do not print two versions of the facts.
- Print Instruction Card A (preponderance of the evidence) for half the class and Instruction Card B (proof beyond a reasonable doubt) for the other half. Shuffle seating or count off by twos so the split is not visible by seat.
- Prepare two ballot slips or two colors of index card, one color per instruction group, so you can tally verdicts by group at the board.
- Draw two columns on the board labeled "Group A verdict" and "Group B verdict" before students arrive.
The run sheet

- Setup. Do not explain the split yet. Hand out the Case File to every student face down. "This is a case I built for today. It is not real, no part of it happened, and you will not find it in any court record. Read it once, quietly, on your own."
- 0:05
- Silent read. Students read the Case File alone. Walk the room. Do not answer questions about the law yet; redirect to "just the facts for now."
- 0:12
- Instruction handout. Hand Instruction Card A to one group and Instruction Card B to the other, face down, telling them not to compare with neighbors yet. "Everyone just got a card telling you the rule you must use to decide this case. Read your card only. Do not read anyone else's."
- 0:16
- Private verdicts. Each student writes guilty or not guilty on their colored card, silently, using only their own instruction. No talking.
- 0:20
- Tally on the board. Collect and count both groups separately, write both totals on the board before anyone explains anything. "I want you to look at these two columns before I tell you why they might be different."
- 0:24
- Reveal. Explain that half the room got a lower bar, "more likely than not," and half got the higher bar, "no reasonable doubt." Let the room react.
- 0:28
- Discussion. Run the questions below in order, cold-calling across both groups.
- 0:41

The case file
State of Ashford v. Dana Reyes
This case is fictional, built for classroom use. Any resemblance to real people or events is unintended and irrelevant.
Dana Reyes managed the equipment room at Coldwater High School for six years. In March, the school discovered that the lock box holding a set of newly purchased laptops, valued near four thousand dollars, was empty. Reyes had the only master key besides the athletic director, who was on medical leave the entire month the laptops went missing.
A security camera outside the equipment room recorded Reyes entering alone at 6:40 a.m. on the morning the laptops were last confirmed present, thirty minutes before the building officially opened. The footage shows her leaving eleven minutes later carrying a large athletic duffel bag she did not have when she arrived. No camera covers the inside of the room.
Reyes testified that she arrived early that day to prepare uniforms for a track meet and that the duffel bag held washed jerseys she had taken home the night before to launder, a task she says she performed regularly and which two team parents confirmed she had done in the past, though neither parent could confirm she did it that specific week.
Three weeks after the laptops disappeared, Reyes sold a laptop of the same model and generation on an online marketplace for two hundred dollars, listing it as "used, some wear." She testified she bought it two years earlier at a yard sale and could not produce a receipt. The serial number on the sold laptop did not match any serial number on the school's purchase invoice, but the school's inventory records for that batch of laptops were incomplete; only nine of the twelve serial numbers had ever been logged.
No fingerprints were taken from the lock box. No other student, teacher, or staff member has been identified as having access to a key or a known motive. Reyes has no prior disciplinary record in six years of employment and volunteered for two additional unpaid hours a week coaching track.
Instruction Card A
You are a juror. Use this rule and no other: find the defendant guilty if, weighing all the evidence, you believe it is more likely than not, that is, more than fifty percent likely, that she took the laptops. If the evidence is evenly balanced or points the other way, find her not guilty. Write your verdict now. Do not discuss it with anyone.
Instruction Card B
You are a juror. Use this rule and no other: find the defendant guilty only if the evidence leaves you with no reasonable doubt that she took the laptops. A reasonable doubt is a doubt based on reason and common sense, not a fanciful or invented one. If any honest, reasonable explanation consistent with innocence remains open to you, you must find her not guilty, even if you think she probably did it. Write your verdict now. Do not discuss it with anyone.
Discussion
"How many of you in the fifty-percent group voted guilty, and how many of you in the reasonable-doubt group voted guilty? Why do you think the numbers moved?"
Expect Group A to convict more often than Group B on the identical facts. If it does not split cleanly, ask a few students from each side to explain their reasoning aloud; the gap in logic will usually still be visible even if the raw numbers are close.
"Group B, was there a moment in the facts where you personally thought she probably did it, but still voted not guilty? What was that moment?"
Push for the duffel bag and the mismatched serial number. Students will often admit suspicion coexisted with a not-guilty vote once they understand the standard is not "what do you believe" but "has doubt been eliminated."
"Is 'probably guilty' ever supposed to be enough to convict someone of a crime? Why require more?"
Let students sit with the asymmetry: the criminal system tolerates guilty people going free more readily than it tolerates innocent people being convicted. Some will resist this instinctively. Do not rush past the resistance.
"Could a juror honestly follow Instruction A and still feel like they were doing justice? Could a juror follow Instruction B and still feel like a guilty person got away?"
This surfaces the discomfort baked into any burden of proof: the rule is chosen in advance, before anyone knows whether it will free a guilty person or convict an innocent one.
"If the incomplete inventory records had been complete, and the serial number definitely matched, would that move Group B's verdicts? What if it definitely did not match?"
Use this to show that reasonable doubt is not a fixed quantity of evidence, it is a relationship between the evidence you have and the certainty it produces. A single fact can flip a verdict without touching the standard itself.
Where the law lands
In a criminal case, the government must prove every element of the charge beyond a reasonable doubt before a jury may convict. That is the highest standard used in ordinary courts, well above the "more likely than not" standard used in most civil disputes, and it exists because a criminal conviction can cost someone their liberty, their record, and their name. A reasonable doubt is not the same as any conceivable doubt; jurors are not asked to achieve mathematical certainty, only to reach a firm conviction of guilt that leaves no honest hesitation grounded in reason. Where reasonable people genuinely disagree is in applying that standard to circumstantial cases exactly like this one: two jurors can look at the same duffel bag and the same mismatched serial number and one will call it proof, the other will call it suspicion, and both will be following the instruction faithfully. The standard tells jurors how sure they must be. It cannot tell them how to feel about ambiguous facts, and that gap is where every real jury deliberation actually lives.
Exit ticket
Write four to six sentences: Using only the "no reasonable doubt" standard, name one specific fact in the case file that, if it had come out differently, would have changed your own verdict, and explain exactly what certainty it would have added or removed. Do not simply restate whether you think she is guilty.
