Criminal Profiling Slides Mind of the Offender
Criminal Profiling: Science vs. Fiction
Forensic Psychology • Lesson 1
The Hollywood Myth
The TV Profiler
• "Psychic" level intuition
• Solves cases in 42 minutes
• Can tell a person's life story from a shoe print
The Forensic Realist
• Based on statistical probability
• A supplementary tool, not a "silver bullet"
• Focuses on behavior, not mind-reading
"Profiling is about what the offender does, not just who they are."
What is Criminal Profiling?
Behavioral Analysis
Analyzing the methods and actions taken during a crime to infer personality traits.
Geographic Profiling
Determining the most likely home base of an offender based on crime locations.
Victimology
Studying the characteristics of victims to understand why they were targeted.
Core Assumption: "The way an offender behaves at a crime scene reflects their behavior and personality in non-criminal life."
The Profiling Process
1
Input
Crime scene photos, autopsy reports, witness logs.
2
Classification
Is the crime Organized or Disorganized?
3
Reconstruction
Determining the sequence of events and behavior.
4
The Profile
Predicting age, occupation, marital status, etc.
The FBI Typology
Organized
High intelligence
Socially competent
Plan the crime in advance
Brings tools/removes evidence
Disorganized
Lower intelligence
Socially immature
Spontaneous/Impulsive
Leaves physical evidence behind
Is it Science?
Barnum Effect
Profiles are often so vague they could fit almost anyone. Like horoscopes, people search for meaning and ignore the misses.
Lack of Empirical Evidence
Research shows professional profilers are only slightly more accurate than college students or detectives at predicting offender traits.

Subject: The Midnight Van Incident
A series of three residential burglaries occurred over the last two weeks in the suburb of Oakwood. All entries were forced through back windows. Notably, high-value electronics were ignored; instead, the intruder took personal items such as photographs, journals, and small kitchen appliances. A neighbor reported seeing a white, unmarked van parked nearby during the second incident. No fingerprints were found, but a muddy footprint (Size 10) was recovered from the flower bed.
Behavior Analysis
Based on the case details, identify three specific behaviors observed at the crime scenes:

Is this crime scene Organized or Disorganized ? Justify your choice with evidence.
The Offender Profile
Predict the following characteristics based on behavioral evidence:
Age Range:
Occupation:
Social Skills:
Marital Status:
Living Situation:
Critical Evaluation
Explain one way your profile could be prone to the "Barnum Effect" (being too vague or general).
If a white van is found registered to a 65-year-old woman with no criminal record, how does that impact the validity of your profile?

Lesson 1: Criminal Profiling Science vs. Fiction
Learning Objectives
Distinguish between media-mythologized "profiling" and clinical investigative psychology.
Apply the FBI's organized/disorganized typology to a hypothetical case study.
Analyze the limitations of behavioral evidence, specifically the Barnum Effect and lack of empirical reliability.
Quick Specs
Grade: 11th Psychology
Duration: 60-90 mins
Format: Direct + Case Study
1. The Hook (10 mins)
Before starting the slides, ask students: "If someone stole your backpack right now, what could a detective tell about them just by looking at the empty spot on your desk?" Briefly debate their answers. Transition into how Hollywood (Criminal Minds, Mindhunter) exaggerates this ability.
2. Visual Instruction (25 mins)
Use the Criminal Profiling Slides . Focus on Slide 5 (Organized vs. Disorganized). Emphasize that these are ideal types —real offenders often show traits of both (mixed offender).
3. Case Study: Midnight Van (30 mins)
Distribute the Midnight Van Case File . Have students work in pairs.
Key Insight for Teacher: The offender in this case is likely "Disorganized." Taking personal, low-value items (journals/kitchen appliances) suggests a fixation/impulse rather than profit. The forced entry via back window is messy. The "white van" is a red herring—students often jump on it because of media tropes.
4. Debrief & Critical Review (15 mins)
Discuss the "Barnum Effect." Ask: "Did you write 'lives alone' or 'has trouble with relationships'? Does that apply to almost every criminal?" Challenge the validity of the typology.
Midnight Van Analysis Key
Likely Traits
Classification: Disorganized/Mixed
Age: Younger (18-25) or socially stunted older male.
Motivation: Power-reassurance or emotional fixation.
Residence: Likely lives very close (oakwood suburb).
Critical Discussion
"Remind students that profiling is not used to identify a specific person, but to narrow a suspect pool. If the police have 500 leads, the profile helps them decide which 5 to interview first."
Eyewitness Testimony Slides Seeing is Believing?
The Reliability of Eyewitness Testimony
Forensic Psychology • Lesson 2
The Impact of Error
70%
Of wrongful convictions overturned by DNA evidence involved eyewitness misidentification.
"It is the single greatest cause of wrongful convictions in the United States." — The Innocence Project
Memory is NOT a Video Camera
Encoding
What you actually see and pay attention to. Stress, lighting, and distance can distort this initial "recording."
Storage
Memory fades over time. New information can overwrite or merge with old memories without you realizing it.
Retrieval
The act of recalling. Leading questions can "reconstruct" the memory in a way that matches the questioner's bias.
Elizabeth Loftus & Malleability
The "Car Crash" Study
Participants saw a video of a car crash. When asked how fast they were going when they smashed, estimates were higher than when asked how fast they hit.
One week later:
"Did you see any broken glass?"
"Smashed" group: Yes! (There was no glass)
Key Term:
Misinformation Effect
Incorporating misleading information into one's memory of an event.
Distortion Factors
Weapon Focus
Witnesses focus on the weapon rather than the perpetrator's face due to extreme stress.
Cross-Race Effect
The tendency to recognize faces of one's own race more easily than those of other races.
Leading Questions
Subtle phrasing that suggests a "correct" answer or implants a false detail.
Memory Decay
The interval between the event and the identification (forgetting curve).
What Did You Actually See?
We are about to test your collective memory. Take out your simulation logs. Be honest—your memory might surprise (and fail) you.

Lesson 2: Reliability of Eyewitness Testimony
Learning Objectives
Explain the three stages of memory (Encoding, Storage, Retrieval) and how each can be compromised.
Demonstrate the "misinformation effect" through a live classroom simulation.
Identify specific legal system vulnerabilities (e.g., weapon focus, cross-race effect).
Prep Required
Must recruit a "perpetrator" (colleague or student from another class) to interrupt the lesson.
Simulation Protocol (The Hook)
The Event: About 5 minutes into class, the "perp" should burst in, perhaps shouting something brief ("Where is it?!"), grab a specific object (like a stapler or a specific student's notebook), and run out. They should stay for no more than 10-15 seconds.
The Clothing: Instruct the perp to wear something standard but unremarkable (e.g., a blue t-shirt, NOT a hoodie).
Immediate Log: Hand out the Simulation Logs immediately. Students must complete Part 1 in absolute silence.
The Interrogation: During Part 2, read the questions aloud. Note: The questions are intentionally loaded. The "hoodie" and "dropping books" are false details. See if students "recall" them.
1. The Reveal (10 mins)
Bring the "perp" back into the room. Have students compare their logs to reality. Discuss how many people "remembered" the hoodie or the books simply because you mentioned them. This is the Misinformation Effect in action.
2. Direct Instruction (20 mins)
Present Eyewitness Testimony Slides . Focus on Elizabeth Loftus's research. Explain that memory is reconstructive, not reproductive.
3. Case Discussion (15 mins)
Discuss Ronald Cotton or other Innocence Project cases where eyewitnesses were 100% certain but 100% wrong. Ask: "If a witness is crying and shaking with certainty on the stand, should a jury believe them?"
Safety Note
Ensure the simulation isn't *too* realistic or threatening. Use a known faculty member if possible to minimize genuine alarm.
Discussion Prompt
"Why do you think juries find eyewitness testimony so much more compelling than DNA or fingerprints, despite its high failure rate?"
Insanity Defense Slides Madness or Malice?
Legal Competency and the Insanity Defense
Forensic Psychology • Lesson 3
The Psychology of the Courtroom
1
Competency (CST)
Does the defendant understand the charges RIGHT NOW and can they help their lawyer?
Timeframe: Current State
2
Insanity (NGRI)
Was the defendant responsible for their actions AT THE TIME of the crime?
Timeframe: Past State
The Standard: M'Naghten (1843)
"To establish a defense on the ground of insanity, it must be clearly proved that, at the time of the committing of the act, the party accused was laboring under such a defect of reason... as not to know the nature and quality of the act... or if he did know it, that he did not know he was doing what was wrong."
The Cognitive Test
Did they know what they were doing? (e.g., thinking a gun was a water pistol).
The Moral Test
Did they know it was wrong? (e.g., hearing "voices of God" ordering the act).
Clinical Mental Illness ≠ Legal Insanity
Clinical
Schizophrenia, Bipolar, Psychosis, PTSD
Diagnosed by Doctors
Legal
"Not Guilty by Reason of Insanity"
Determined by Jury/Judge
Crucial Fact: One can have a severe mental illness (clinical) but still be found legally sane if they understood their actions were wrong.
The Case of John Hinckley Jr.
• Attempted to assassinate President Reagan in 1981.
• Claimed he did it to impress actress Jodie Foster.
• Found Not Guilty by Reason of Insanity.
• Resulted in massive public outrage and the Insanity Defense Reform Act (1984).
Myths vs. Reality
Myth: Used frequently.
Reality: Used in < 1% of felony cases.
Myth: A "get out of jail free" card.
Reality: Defendants often spend MORE time in secure psych facilities than they would have in prison.
You are the Judge
We will now review three cases. You must decide: Competent? Insane? Or simply Guilty? The burden of proof is on you.

Jurist:
Case Alpha: The Silent Defendant
Status: Pre-Trial
Defendant Sarah L. is charged with grand larceny. During meetings with her lawyer, she refuses to speak, stares at the ceiling, and insists that the judge is actually a hologram projected by a rival corporation. She cannot name the charges against her or explain the role of a jury.
Legal Question:
Is Sarah Competent to Stand Trial (CST)?
Yes
No
Reasoning (Reference CST Standards):
Case Beta: The Command Hallucination
Status: Trial Phase
Defendant Marcus V. suffers from chronic paranoid schizophrenia. He assaulted a stranger in a park, claiming a voice he believed to be an angel told him the stranger was a demon about to destroy the world. Marcus stayed at the scene and told arriving officers he was "saving humanity."
Legal Question:
Does Marcus meet the M'Naghten Rule for Insanity?
Did he know the nature of the act?
Did he know it was wrong?
Case Gamma: The Planned Revenge
Status: Trial Phase
Defendant Elena R. has been diagnosed with Clinical Depression. After being fired, she waited in the parking lot for four hours for her boss to exit, then intentionally rammed his car. Evidence shows she deleted her browser history and hid the car keys afterward.
Can Elena use the Insanity Defense? Explain why "Clinical Illness" does not automatically equal "Legal Insanity" here.

Insanity Defense Teacher Guide Teacher Guide: Madness or Malice?
Lesson 3: Legal Competency and the Insanity Defense
Learning Objectives
Distinguish between Competency to Stand Trial (present state) and the Insanity Defense (past state).
Apply the M'Naghten Rule (Cognitive and Moral prongs) to case scenarios.
Critically evaluate the societal and legal impact of high-profile NGRI verdicts.
Essential Question
"How does the law balance the need for public safety with the principle that a person must be mentally responsible to be punished?"
1. The Hook (10 mins)
Present the John Hinckley Jr. case (Slide 5). Ask students: "If someone tries to kill the President because they think it will make a movie star fall in love with them, are they evil or just broken?" Let them debate before introducing the legal definitions.
2. Visual Instruction (25 mins)
Use Insanity Defense Slides . Focus heavily on Slide 2 (CST vs. NGRI). Students often confuse these. CST is about the now ; NGRI is about the then .
3. Case Analysis Activity (30 mins)
Distribute Mental State Case Studies Worksheet . Have students work in small "judicial panels."
Assessment Key
Case Alpha (Sarah L.)
Verdict: Incompetent (CST). Sarah fails both prongs: understanding the charges (believes they are holograms) and assisting her lawyer (refusal to speak). The trial must be paused for "restoration of competency."
Case Beta (Marcus V.)
Verdict: Likely Insane (NGRI). Meets the Moral Test of M'Naghten. Because he believed the victim was a demon and that he was "saving humanity," he did not know his act was wrong in his own mind.
Case Gamma (Elena R.)
Verdict: Guilty. While clinically depressed, she showed planning (waiting 4 hours) and consciousness of guilt (deleting history, hiding keys). She understood the nature and wrongfulness of the act.
Extension Idea:
Have advanced students research the "Guilty But Mentally Ill" (GBMI) verdict used in some states as an alternative to NGRI. What are the ethical implications?
Jury Selection Slides The Twelve Angry (or Biased) Men
Jury Selection and Courtroom Psychology
Forensic Psychology • Lesson 4
Voir Dire: "To Speak the Truth"
The preliminary examination of a juror by a judge or counsel.
The Attorney's Goal:
To identify and remove jurors who are biased—or to select jurors who are likely to favor their side of the case.
?
Can you ever truly find a "neutral" juror?
Striking a Juror
Challenge for Cause
• Must provide a specific legal reason (e.g., related to the defendant).
• The juror is clearly biased or unfit.
• Unlimited number of these.
Peremptory Challenge
• No reason needs to be given.
• Based on "gut feeling" or strategy.
• Limited number (usually 6-10 per side).
• Cannot be used solely based on race or gender (Batson Challenge).
The Psychology of Strategy
Demographics
Attorneys look for correlations between age, income, and political leanings and trial outcomes.
Non-Verbal Cues
Eye contact, posture, and clothing choices are analyzed by trial consultants.
Implicit Bias
Unconscious attitudes or stereotypes that affect our understanding and decisions.
"The trial is often won or lost before the first witness ever speaks."
Who Would You Strike?
Traditional (though sometimes flawed) Attorney Strategy:
Defense tends to like:
"Social workers, creatives, people with anti-authoritarian streaks, those with personal struggles."
Prosecution tends to like:
"Business owners, military, engineers, people who value order and rules."
⚠️ Note: These are generalizations used in strategy, not universal truths!

Key Terminology
Voir Dire • Peremptory Challenge • Implicit Bias • Batson Challenge • Scientific Jury Selection
1. The Hook (10 mins)
Ask: "If you were on trial for a crime you didn't commit, would you want a jury of 12 people who are exactly like you, or 12 people who are completely different?" Discuss the idea of "impartiality" vs. "favorability."
2. Instruction (25 mins)
Present Jury Selection Slides . Emphasize that while peremptory challenges seem arbitrary, they are often based on massive amounts of statistical research conducted by "Trial Consultants."
3. Activity: Voir Dire Simulator (30 mins)
Distribute the Juror Profile Cards .
Strategy Notes: Split the class into Prosecution and Defense teams. Each team must look at the 4 cards and decide their "Strikes."
Prosecution Logic: Would likely strike Juror #02 (empathic art teacher) fearing she might be too lenient or anti-authority.
Defense Logic: Would likely strike Juror #01 (retired military) fearing a "law and order" bias, or Juror #03 (accountant) if the defense relies on emotional appeal rather than hard logic.
The Psychology of the Batson Challenge
Remind students that while peremptory challenges don't require a reason, they cannot be used to exclude jurors based on race, gender, or religion. If an attorney suspects this is happening, they can issue a "Batson Challenge," requiring the other side to prove a race-neutral reason for the strike.
"Is jury selection about finding 12 'fair' people, or is it about finding the 'right' 12 people for your side?"
Forensic Capstone Case File Document Federal Investigative Bureau • Division of Behavioral Science
CASE FILE: COLD CASE #88-RED
DECLASSIFIED FOR ANALYSIS
Subject Overview
Victim: Thomas Miller, Age 34
Crime: Aggravated Assault / Robbery
Status: Wrongful Conviction Suspected
Critical Evidence
I. The Investigation
The initial profile constructed by local police suggested an organized offender due to the lack of fingerprints at the scene. They focused their search on high-intelligence professionals. However, the scene was chaotic; multiple items were broken without reason, and the perpetrator left a partially eaten sandwich on the kitchen counter.
II. The Eyewitness
A neighbor, Ms. Gable (Age 72), identified the suspect in a lineup three weeks later. Police interrogation records show the detective asked: "You saw the man with the dark jacket and the scar, didn't you?" Ms. Gable replied "I think so," and later testified she was "certain" of the scar, though no scar was mentioned in her initial 911 call.
III. The Defendant's State
Defendant Leo K. was arrested. At trial, he insisted he was being framed by "interdimensional spiders." His lawyer did not request a competency evaluation, and Leo was found guilty. He is currently serving 15 years.
IV. The Jury
Post-trial interviews reveal that the jury consisted entirely of engineers and accountants. They noted that the "scientific-sounding" profile provided by the prosecution was the deciding factor in their verdict.

Project Goals
This capstone requires students to synthesize information from all four prior lessons. They must identify how multiple psychological failures cascaded into a wrongful conviction.
Cold Case #88-RED Answer Key
I. Profiling Error
Investigators misclassified the scene as Organized. The broken items and partially eaten food are hallmarks of a Disorganized offender. By focusing only on professionals, they missed local suspects.
II. Memory Error
The detective used a Leading Question ("...dark jacket and the scar, didn't you?"). This triggered the Misinformation Effect, implanting the memory of a scar that didn't exist in the initial 911 call.
III. Mental State Error
The defendant's belief in "interdimensional spiders" indicates a lack of Competency to Stand Trial (CST). He was unable to rationally assist his lawyer. This trial should have been paused for clinical evaluation.
IV. Jury Bias
The defense failed to strike jurors who were overly analytical/rigid (accountants/engineers). These jurors were swayed by the "scientific" appearance of the flawed profile, failing to see the human errors in the investigation.
Grading Rubric
Criteria Mastery (4) Developing (2) Beginning (1) Concept Application Correctly identifies and defines all 4 psychological concepts. Identifies 2-3 concepts; some definitions are vague. Concepts are misidentified or missing. Evidence Usage Cites specific details from the Case File for every claim. Cites some evidence but remains general in parts. Claims are made without citing the Case File. Legal Reasoning Clearly explains how the error led to a flawed verdict. Mentions the error but impact is unclear. No logical link between error and outcome.
Pacing Tip:
Give students 45 minutes of quiet analysis time, then allow them 15 minutes to "confer with colleagues" (partners) before finalizing their reports. This mirrors the collaborative nature of legal review.
