FAQ
What is the IPIP‑50?
A 50‑item public‑domain set from the International Personality Item Pool (IPIP) representing Goldberg’s Big‑Five factor markers. It yields five 10‑item trait scores.
How is it scored?
Each item is 1–5 from Very inaccurate to Very accurate. Some items are reverse‑scored. Each trait is the mean of its 10 items on a 1–5 scale.
Are there cutoffs or diagnoses?
No. The Big Five describes normal personality. We label ranges as lower, typical, or higher to help interpretation; these are not clinical severities or diagnoses. IPIP suggests interpreting relative to a sample mean and SD where possible.
Is it free to use?
Yes. IPIP items and scales are in the public domain; you may copy and use them with citation.
Will my answers be stored?
No. Everything runs on your device. The shareable link encodes your scores in the URL hash; our servers do not store responses.
