Begin with evidence doctrine
Character doctrine focuses on the inference. Evidence is generally barred when offered to prove a trait and then infer conduct in accordance with that trait on the occasion. Other-act evidence likewise cannot support a disguised propensity chain. It may be offered for a genuine non-propensity purpose such as motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident. The familiar mnemonic is a memory aid, not a test. The proponent must articulate the precise intermediate inference, relevance, sufficient proof, notice where required, and permissible scope; balancing and limiting instructions remain separate.
Propensity prohibition
The character and prior-act rules prohibit specified propensity uses. official-source fixture (not neochart). Verbatim selected rule text: “Evidence of a person’s character or character trait is not admissible to prove that on a particular occasion the person acted in accordance with the character or trait. Evidence of any other crime, wrong, or act is not admissible to prove a person’s character in order to show that on a particular occasion the person acted in accordance with the character.” Source: Fed. R. Evid. 104, 201, 301, 401-405, 501, 601-611, 702, 801-804, 901, 1001-1004; https://www.uscourts.gov/sites/default/files/document/federal-rules-of-evidence.pdf.
Permitted purposes and proof methods
The rules list non-propensity purposes and distinguish reputation, opinion, and specific-instance proof. official-source fixture (not neochart). Verbatim selected rule text: “This evidence may be admissible for another purpose, such as proving motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident. When evidence of a person’s character or character trait is admissible, it may be proved by testimony about the person’s reputation or by testimony in the form of an opinion. On cross-examination of the character witness, the court may allow an inquiry into relevant specific instances of the person’s conduct. When a person’s character or character trait is an essential element of a charge, claim, or defense, the character or trait may also be proved by relevant specific instances of the person’s conduct.” Source: Fed. R. Evid. 104, 201, 301, 401-405, 501, 601-611, 702, 801-804, 901, 1001-1004; https://www.uscourts.gov/sites/default/files/document/federal-rules-of-evidence.pdf.
Relevance balancing remains
A permitted purpose still must pass relevance, other admissibility rules, and unfair-prejudice balancing. official-source fixture (not neochart). Verbatim selected rule text: “Evidence is relevant if: it has any tendency to make a fact more or less probable than it would be without the evidence; and the fact is of consequence in determining the action. The court may exclude relevant evidence if its probative value is substantially outweighed by a danger of one or more of the following: unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence.” Source: Fed. R. Evid. 104, 201, 301, 401-405, 501, 601-611, 702, 801-804, 901, 1001-1004; https://www.uscourts.gov/sites/default/files/document/federal-rules-of-evidence.pdf.
Pin the synthetic evidence record
A synthetic payment-account allegation and an earlier access anomaly are represented with actors, systems, methods, dates, similarity, differences, adjudication status, stated purposes, alternate explanations, and requested limiting use.
Work the admissibility application
The table rejects a direct bad-character-to-conduct inference. It tests identity by asking whether distinctive similarities genuinely support authorship and tests absence of mistake through the claimed knowledge chain. Each purpose must be consequential and supported without propensity, after which proof sufficiency, notice, balancing, and limiting instruction are evaluated.
Read the populated evidence record
The character record contains item, person, trait, charged event, other event, offered purpose, forbidden propensity chain, permitted intermediate proposition, consequential fact, similarity, difference, proof source, character exception, proof method, notice, balancing, limiting instruction, ruling, and unresolved objection. The record contains 14 populated rows.

Read the complete record
The complete record keeps sources, stated facts, and questions for review separate. Pinned sources: Verbatim snapshot or official authority. Fed. R. Evid. 104, 201, 301, 401-405, 501, 601-611, 702, 801-804, 901, 1001-1004: Propensity prohibition: Propensity prohibition. Fed. R.

Charged event: Employee is accused of altering a vendor payment account. Prior event: Earlier access-log anomaly involved a different vendor and was never adjudicated. Purposes: Proponent states identity and absence of mistake; opponent argues the reasoning is forbidden propensity. Admissibility trace: Purpose, rule, foundation, objection, response, ruling, and limitation. Inference path: Item to intermediate proposition to consequential fact; reject person did it before therefore did it now. Non-propensity uses: Motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident; familiar mnemonic is illustrative, not exhaustive. Genuine issue: Purpose must matter and reasoning must not merely relabel propensity. Method and controls: Character exception, reputation or opinion, essential-element specific acts, notice, proof, balancing, limiting instruction.
Narrow summary
Expose the inference chain, reject propensity reasoning, and require a genuine consequential non-propensity purpose plus ordinary admissibility safeguards.
