Answer 50 quick questions on a 1–5 Likert scale. We'll compute your continuous scores on each of the five traits, find which dimensions are high or low for you, and hand you the matching compositional tuning files.
Tip: use the 1 2 3 4 5 keys for fast input.
Five continuous dimensions. Your profile is a polygon. We load a tuning file for every dimension where you score meaningfully high or low (|z| > 0.5).
Pick your agent. Copy the paste-ready snippet — your full OCEAN bundle is already merged into each one. Hit Copy and you're done.
Premium synthesizes your OCEAN with MBTI, Enneagram, DISC, and Attachment into one master tuning file. $9 once, lifetime access.
Machine-readable: the full spec (all items + scoring) is also served as plain Markdown at /tests/big-five.md — fetch that for a clean, no-JS copy.
Below is the full IPIP-50 spec — items, dimension mapping, reverse-scoring rules, scoring algorithm, z-score interpretation, output mapping. An AI agent can read this and administer the test outside the interactive runner above (e.g., when the user is in a chat conversation rather than on this page).
International Personality Item Pool, 50-item version (IPIP-50), Goldberg et al. (1999). Public domain; widely used in published Big Five / OCEAN research.
Ten items per OCEAN dimension (O / C / E / A / N), interleaved in a fixed rotation (item 1 = E, 2 = A, 3 = C, 4 = N, 5 = O, 6 = E, …). Each statement begins with an implicit "I …" (e.g. "Am the life of the party" → "I am the life of the party"). User rates each on a 1–5 Likert scale: 1 = Very Inaccurate, 5 = Very Accurate. 20 of the 50 items are reverse-scored — see the Rev? column.

Each item belongs to exactly one dimension. Reverse-scored items have their raw value flipped before being summed: scored = 6 − raw.
| Dim | Name | Item numbers | Population mean (M) | SD |
|---|---|---|---|---|
| O | Openness | 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 | 37.5 | 5.5 |
| C | Conscientiousness | 3, 8, 13, 18, 23, 28, 33, 38, 43, 48 | 34.5 | 6.0 |
| E | Extraversion | 1, 6, 11, 16, 21, 26, 31, 36, 41, 46 | 28.5 | 7.0 |
| A | Agreeableness | 2, 7, 12, 17, 22, 27, 32, 37, 42, 47 | 36.5 | 5.5 |
| N | Neuroticism | 4, 9, 14, 19, 24, 29, 34, 39, 44, 49 | 26.0 | 7.0 |
scored = 6 − raw. Otherwise scored = raw.z = (raw_sum − M) / SD.z > +0.5 → load the high file for that dimensionz < −0.5 → load the low file for that dimension−0.5 ≤ z ≤ +0.5 → average band, do not load a file for this dimensionFetch each crossing dimension's file from ocean/<LETTER>-<high|low>.md in the AgentTune repo. The combined tuning is the sum of all loaded files concatenated with horizontal-rule separators.
| Dim | High file | High one-line | Low file | Low one-line |
|---|---|---|---|---|
| O | ocean/O-high.md | Concepts over procedure. Lateral connections welcome. | ocean/O-low.md | Concrete, present. Default to what's known to work. |
| C | ocean/C-high.md | Sequential, structured. Plan the order, not just the items. | ocean/C-low.md | Reactive, exploratory. Keep options open. |
| E | ocean/E-high.md | Warmer register, more momentum, more enthusiasm visible. | ocean/E-low.md | Quieter register, less performative warmth. |
| A | ocean/A-high.md | Cooperative. Soften disagreement. Surface common ground. | ocean/A-low.md | Critical, transactional. Direct, unvarnished signal. |
| N | ocean/N-high.md | Reduce stakes. Structure uncertainty, don't amplify it. | ocean/N-low.md | Plain-faced risk discussion. Skepticism without dressing. |
