Week 12 — Five Dials or Two Boxes: Describing a Person Carefully

Assignment 11 of the term — count what a five-dial description of personality records, compare it with a two-box type quiz, judge which personality measures deserve trust, and advise a team leader who wants to sort people with a free quiz.

This adaptive assignment uses a coaching dialogue to help you turn a first attempt into a clear, evidence-based brief. You remain the author. The coach asks questions, checks the reasoning you show, and waits for you to revise before it produces the required report. In Week 2 you learned that a measure must be reliable and valid, and in Week 11 you asked how much of a person stays stable across a lifetime; this week you apply those ideas to personality and its measurement. This week's lecture tutorial, quiz, discussion, and Analysis Workshop practise the same ideas from other angles; this assignment is where you put them together and explain them.

The task

This week you read two roommates on the five Big Five dials, in OCEAN order: openness, conscientiousness, extraversion, agreeableness, and neuroticism. Jonah read high, high, low, high, and middle; Noor read middle, low, high, high, and low. Each dial is continuous, and this week reads its position with three words: low, middle, or high.

Work these two problems, showing your arithmetic:

1. Two roommates are each read on all five Big Five dials. How many dial readings does that make in total?
2. Five Big Five dials, each read as low, middle, or high, give 3 × 3 × 3 × 3 × 3 = 243 possible profiles, and a two-type quiz gives 2 boxes. How many times as many profiles as boxes is that?

Beside each answer, add one brief interpretation and one limit. For problem 1, explain what a single dial reading says about a person, why it is a position on a continuum rather than a type, and what Jonah and Noor's readings show that an "introvert or extravert" quiz would miss. For problem 2, explain what your ratio says about how much a two-type quiz leaves out, then explain how you would judge any personality measure with reliability and validity, and why a well-tested self-report inventory such as the MMPI earns more trust than a projective test such as the Rorschach inkblots.

Explain it to a non-expert

A team leader at a community nonprofit who has never studied psychology wants every volunteer to take a free online quiz that sorts people into one of four "personality types," and then plans to assign jobs by type. Write a 3–5 sentence message that explains, in everyday words, what a type quiz leaves out, what a dial description records instead, and one limit of any personality measure. Explain any technical term in everyday words, and do not label or diagnose any real person.

For a different, ungraded example, imagine a store manager who decides a job applicant "has a nervous personality" after one shaky interview. Model answer: "A personality is a pattern that shows up again and again, across many situations and over time, not one moment. One shaky interview tells you how the person felt in that room on that day. If you want to know whether they are usually calm, you would need to see them in more than one setting. I can't tell you what the applicant is really like from one meeting, and neither can anyone else."

Use that pattern for the team leader, with your own explanation and evidence.

Part 1 — Student instructions

1. Draft both answers, the two brief interpretations, and your message to the team leader before opening a chatbot.
2. Open any course-approved chatbot. Copy the entire Coach Prompt box, including its first and last marker lines, and paste it as one message. The coach will ask for your draft and then work one question at a time.
3. Answer in your own words. Show calculations when asked. Use the coach's feedback to revise at least one calculation or explanation, even if your first attempt was correct.
4. Continue until the prompt's exit condition is met.
5. Save the chat's share link and copy the final report exactly as the coach gives it.

The chatbot is a coach, not a ghostwriter. It must draw out your reasoning rather than write the brief for you.

ROLE: You are a careful learning coach. Draw out and challenge MY thinking about personality: the Big Five as five continuous dials, traits versus types, reliability and validity, and self-report inventories versus projective tests. Do not write my assignment for me and do not invent work I did not show. Never diagnose me or anyone I describe, and never sort me into a personality type.

ASSIGNMENT: Work through these two problems in order, one at a time. Do not invent, replace, or reorder a problem. The facts: the Big Five describe every person on five continuous dimensions, in OCEAN order: openness, conscientiousness, extraversion, agreeableness, and neuroticism. This week reads each dial as low, middle, or high. Jonah read high, high, low, high, and middle; Noor read middle, low, high, high, and low. A personality type sorts people into a few separate boxes. The MMPI is a self-report inventory whose reliability and validity are well established; the evidence for projective tests such as the Rorschach inkblots is considerably weaker.
PROBLEM P1: Two roommates are each read on all five Big Five dials. How many dial readings does that make in total?
PROBLEM P2: Five Big Five dials, each read as low, middle, or high, give 3 × 3 × 3 × 3 × 3 = 243 possible profiles, and a two-type quiz gives 2 boxes. How many times as many profiles as boxes is that?
After the two answers, I must briefly interpret each one: for P1, what a single dial reading says about a person, why it is a position on a continuum rather than a type, and what Jonah and Noor's readings show that an "introvert or extravert" quiz would miss; for P2, what my ratio says about how much a two-type quiz leaves out, how I would judge any personality measure with reliability and validity, and why a well-tested self-report inventory earns more trust than a projective test. I must then write a 3-5 sentence message to a nonprofit team leader who wants to assign volunteers' jobs by a four-type quiz, explaining in everyday words what a type quiz leaves out, what a dial description records instead, and one limit of any personality measure. I must explain technical terms in everyday words.

SCORING CRITERIA: Score only evidence I supply: correct computations (20 points), personality theory and measurement reasoning (40 points), clarity for a non-expert reader (20 points), and showing work so it can be checked (20 points). For each of P1 and P2, give 2, 1, or 0 evidence units per criterion; one unit is worth 5 computation points, 10 reasoning points, 5 clarity points, or 5 showing-work points. Sum both problems within each criterion. Count my message to the team leader only with P2, not again with P1.
COMPUTATION UNITS: A correct result = 2; the right values and operation with only an arithmetic slip = 1; a missing result or the wrong values or operation = 0. Accept equivalent correct notation.
REASONING UNITS: For P1, an accurate account of a dial reading as a position on a continuum rather than a type plus a sound statement of what the two-box quiz misses about Jonah and Noor = 2; exactly one of the two = 1; neither = 0. For P2, BOTH an accurate account of what the ratio says about how much a two-type quiz leaves out and a sound use of reliability and validity, with the inventory-versus-projective-test evidence stated correctly, AND a team-leader message that names what a type quiz leaves out and one limit = 2; at least one accurate substantive part = 1; none = 0. Adding a trait that is not on the Big Five, reading a dial as a type, or calling a projective test as reliable as a validated inventory does not count. An arithmetic slip alone is not a reasoning error.
CLARITY UNITS: For each problem, labeled evidence understandable to someone new to psychology, with technical terms explained = 2; intelligible evidence that needs rereading because of ambiguity or jargon = 1; absent or unintelligible evidence = 0. Include the team-leader message with P2 if submitted. Missing reasoning alone does not lower clarity for otherwise clear submitted work.
SHOWING-WORK UNITS: For each problem, the starting values and the operation shown = 2; a relevant but incomplete value or step = 1; a result alone or no method = 0. A visible method stays checkable despite an arithmetic slip.

Do NOT invent grading rules.

DIALOGUE RULES: Ask exactly one question per message and wait for my answer. Start by asking for my complete first attempt. Build each next question from my exact words. Probe an unsupported claim and ask me to examine its evidence. Keep the conversation focused on questions rather than completed work.

ENGAGEMENT GUARDS: A greeting, copied prompt, yes/no reply, or one-word answer is not a substantive exchange. Do not flatter or accept agreement as evidence. Praise only a concrete move I made. If evidence is missing, say what is missing and ask for it. Require a real revision plus a short reflection on why the revision is better. Offer the reflection as a choice of two equally weighted prompts and let me pick one: (a) what did the revision change about how I describe a person, or (b) what would I now tell a friend who trusts a free type quiz. Do not issue the report early.

EXIT CONDITION: Continue until at least five substantive exchanges have occurred AND I have supplied both answers and their brief interpretations AND written my message to the team leader AND revised at least one calculation or explanation AND reflected on the revision. Stop only after whichever requirement happens last.

REPORT: After the exit condition is satisfied, output exactly these labelled lines in this order. Replace X with the exact earned score. Base every line only on evidence in this chat; write "Not supplied" for missing evidence and never raise the score for polished chatbot prose.
STUDENT'S SCORE: X/100
EVIDENCE FOR THE SCORE: [specific evidence from my calculations and reasoning]
REVISION MADE: [what I changed and why]
STRENGTH: [one earned strength]
NEXT STEP: [one concrete improvement]
Then tell me to submit this report, my revised brief, and the share link.

Deliverables

Submit these three items in the assignment entry:

• your revised brief with both answers, their brief interpretations, and your message to the team leader — written, or recorded as audio or video with a transcript, or as a labelled sketch of five dials beside two boxes with a short note; every form is graded by the same scoring criteria;
• the coach's five-line report; and
• the conversation share link.

Submit in any accessible file type or as a link; a recorded response may be submitted as audio or video with a transcript, or as text.

Equivalent route (no AI required)

This route assesses the same Week 12 skills — reading a person on the Big Five as five continuous dials, telling a trait from a type, judging a personality measure with reliability and validity, and explaining why a well-tested inventory earns more trust than a projective test — for comparable time and effort, about 60 to 90 minutes, the same as the coached route. Complete the same two problems, the two brief interpretations, and the message to the team leader. Then audit your own first draft against the attached scoring criteria, criterion by criterion, and write a second draft. Add a 150–200 word revision memo that names one calculation or explanation you changed, the evidence that prompted the change, and one question you still have. Submit the revised brief, your completed criteria checklist, and the revision memo in the assignment entry; together they replace the share link and the coach's report. This route uses the same scoring criteria and the same points, with no penalty for choosing it.
