Is this Big Five test free?

Yes. No account, no trial, no ads. The scoring runs in your browser and nothing is uploaded.

Where do the 120 questions come from?

From the IPIP-NEO-120 (Johnson, 2014), a public-domain inventory of 120 items covering 30 facets. The English item text is the original. The Chinese text is our own first-person translation.

Why is there no personality type?

Because types are a lossy compression of five continuous dimensions. Four letters cannot carry 30 facets, and people treat the label as an identity rather than a snapshot.

Are the scores percentiles?

No. They are positions on a 0–100 scale built from item means. We have no population norms, so we do not claim you are above a certain percentage of people.

A 120-item Big Five test, without the type label

Q: What is the difference between 50 and 120 items?

The 50-item version gives the five broad domains. The 120-item version splits each domain into six facets, so you can see which part is driving the score.

Five domains, thirty facets, scored in your browser. Twenty minutes. No account, and no four-letter code at the end.

Public-domain items. Nothing leaves your device.

What it measures

Five continuous dimensions. Every one of them is a scale, not a category — you are not "an introvert", you are somewhere on a line, and that position moves.

Domain	What it is about
Neuroticism · 情绪敏感度	How easily you are pulled into worry, anger, low mood. Six facets: anxiety, anger, depression, self-consciousness, immoderation, vulnerability.
Extraversion · 外向度	Where your energy comes from. Six facets: friendliness, gregariousness, assertiveness, activity level, excitement-seeking, cheerfulness.
Openness · 开放度	Appetite for ideas, beauty, novelty. Six facets: imagination, artistic interests, emotionality, adventurousness, intellect, liberalism.
Agreeableness · 亲和度	How much you accommodate other people. Six facets: trust, morality, altruism, cooperation, modesty, sympathy.
Conscientiousness · 尽责度	Planning and follow-through. Six facets: self-efficacy, orderliness, dutifulness, achievement striving, self-discipline, cautiousness.

Why 120 instead of 50

A 50-item version gives you the five headline numbers. That is enough for an outline and not enough for an explanation. If your extraversion comes out low, the useful question is which part — you may be low on assertiveness and perfectly fine on friendliness. Those lead to very different next steps. The 120-item version splits each domain into six facets so that question becomes answerable.

The trade is time: about twenty minutes instead of eight. If you have not done the short one yet, do that first.

How it is scored

Each item is answered on a five-point scale from "very inaccurate" to "very accurate".
Some items are reverse-keyed and flipped (6 minus the answer).
A facet is the mean of its four items; a domain is the mean of its twenty-four.
Means are mapped linearly onto 0–100 for display.

We checked this against an independent reference implementation of the same inventory: the reverse-keyed item list matches exactly, the item-to-facet assignment matches on all 30 facets, and the facet sums are identical across four published answer sets. What we cannot do is turn those numbers into percentiles — that needs population norms by age and sex, which we do not have. So we do not print them.

What it is not

Not a diagnosis. It says nothing about your mental health, and a high or low score is not a disorder.

Not a type. No four-letter code, no number, no animal. A label is convenient to repeat and useless to think with.

Not a ranking. There is no better or worse profile. A trait that hurts in one job helps in another.

Not permanent. Take it in a bad month and again in a good one; the difference is the interesting part.

How to read your result

Start with the two extremes and ignore the middle. Most of the middle is noise. Then open the facets under your extremes — that is where the sentence you can actually use lives ("I am not low on sociability, I am low on assertiveness").

Then wait. One measurement is a snapshot; two measurements six weeks apart are a signal.

Questions

Is it really free?

Yes — no account, no ads, no trial. Scoring happens in your browser.

Where do the questions come from?

The IPIP-NEO-120 (Johnson, 2014), a public-domain inventory. The English wording is the original. The Chinese is our own first-person translation, not a validated Chinese edition — we say so on the test page too.

Can I keep the results?

They stay in this browser and stack up as a history, so you can compare across months. Export your data from Settings if you want a file.

Do you use the results for AI?

Not unless you explicitly hand them over. Nothing is uploaded by default.

120 题的大五人格，不给你贴一个类型

五个方向、三十个面向，在你自己的浏览器里算分。二十分钟，不用注册，最后也不会发给你四个字母。

开始测试 →

公有领域题目。数据不离开你的设备。

它测什么

五个连续的维度。每一个都是刻度，不是格子——你不是「一个内向的人」，你是在某条线上某个位置，而这个位置会动。

方向	说的是什么
情绪敏感度	多容易被担心、愤怒、低落拉走。六个面向：焦虑、愤怒、低落、自我意识、冲动、脆弱。
外向度	你的力气从哪来。六个面向：友善、合群、果断、活跃、寻求刺激、愉快。
开放度	对想法、美、新东西的胃口。六个面向：想象、审美、情感、冒险、思辨、开放立场。
亲和度	你为别人让多少。六个面向：信任、直率、利他、合作、谦逊、共情。
尽责度	计划与坚持。六个面向：自我效能、条理、尽责、成就追求、自律、谨慎。

为什么是 120 题，不是 50

50 题给的是五个大数，够看轮廓，不够解释。如果你的外向度偏低，真正有用的问题是「低在哪一块」——你可能只是低在果断，友善一点不低。这两种情况，下一步该做的事完全不同。120 题把每个方向拆成六个面向，这个问题才答得出来。

代价是时间：二十分钟，不是八分钟。短的还没做，先做短的。

分数怎么算的

每题按五档作答，从「非常不像我」到「非常像我」。
反向题翻转（6 减原值）。
一个面向＝它那 4 题的均值；一个方向＝24 题的均值。
均值线性映射到 0–100 显示。

这套算法我们跟同一量表的独立参考实现比过：反向题清单完全一致，30 个面向的题目归属全部一致，四组公开作答的面向求和完全相同。做不到的是把这些数变成百分位——那需要按年龄和性别的常模，我们没有，所以不印。

它不是什么

不是诊断。它说明不了你的心理健康状况，分数高低不等于任何障碍。

不是类型。没有四个字母、没有编号、没有动物。标签好记，但没法用来思考。

不是排名。没有更好的画像。一个特质在这份工作里是拖累，在另一份里是长处。

不是定终身。状态差的月份测一次，状态好的月份再测一次，中间那段差别才是信息。

怎么看结果

先看两个极端，忽略中间——中间大部分是噪声。然后展开极端下面的面向，那句话才用得上（「我不是不合群，我是低在果断」）。

然后等一等。一次是快照，隔六周的两次才是信号。

常见问题

真的免费吗？

免费。不注册、没有广告、没有试用期，算分在你浏览器里完成。

题目哪来的？

IPIP-NEO-120（Johnson, 2014），公有领域量表。英文是原句；中文是我们按原文重译的第一人称版本，不是经过校验的中文修订版——测试页上也这么写。

结果能留住吗？

留在这个浏览器里，会按时间堆成记录，可以对比几个月的变化。想要文件，去设置里导出。

会把结果用于 AI 吗？

除非你明确交出去，否则不会。默认什么都不上传。
