※We have developed the HEXACO-JP Personality Assessment! It has more scientific basis than MBTI. Tap below for details.

Overview of HEXACO

What is HEXACO?

HEXACO answers the question “Why are people so different from each other?”
It’s a relatively new model that describes human personality through six factors.
It derives its name from the six letters H-E-X-A-C-O.
Each represents an important aspect of personality.

Specifically, it includes the following factors:

• H: Honesty-Humility
• E: Emotionality
• X: eXtraversion
• A: Agreeableness
• C: Conscientiousness
• O: Openness

You’ve probably wondered “What kind of person am I?” at some point.
HEXACO becomes the key to answering such questions.
It’s more accurate than the traditional Big Five, with the addition of the new factor of Honesty-Humility.
This allows for more detailed and precise analysis of human personality.

  • Low → Dark (D: Dark)
• E: Emotionality
  • High → Turbulence (T: Turbulence)
  • Low → Assertiveness (A: Assertiveness)

INTP-A (Logician-Assertive) Detailed Analysis with 10+ Papers

Characteristics of INTP-AD

Characteristic ①”Logical Thinking and Creativity”

Don’t you feel compelled to pursue something thoroughly when you wonder “Why does this happen?”
People with INTP-AD have logical thinking like a precision machine.
At the same time, they generate innovative ideas that no one else thinks of.
With an attitude of “Common sense? That doesn’t matter,” they confidently assert their own ideas.
However, they tend to prioritize curiosity of “this seems interesting” over ethical considerations.

Your mind probably works like this:

• Logical analysis like solving complex puzzles
• Abstract thought experiments of “What if this were the case?”
• Creating innovative ideas that no one else can think of

However, this intellectual strength can sometimes become a weakness.
Even when you think “It’s logically correct, so there should be no complaints,” others may get hurt.
Furthermore, the confidence that “my ideas are absolutely correct” makes it difficult to accept criticism.
As a result, you may be seen as “intelligent but difficult to get along with.”
In other words, your logical talent is wonderful, but balance with people is a challenge.

Characteristic ②”Confident Curiosity”

Have you ever felt the intuition that “This will definitely lead to interesting discoveries!”?
People with INTP-AD have curiosity like an explorer.
Rather than fearing failure, they have a strong mentality that views “failure as valuable data.”
This attitude becomes the driving force for groundbreaking discoveries and innovative ideas.
However, it can sometimes appear as arrogance of “I can do anything.”

Your curiosity manifests in these ways:

• Active participation in intellectual debates asking “Is this theory really correct?”
• Challenging difficulties with the attitude “Problems no one can solve are the most interesting”
• Learning motivation of “Let’s try learning this anyway” toward new technologies and theories

This confidence is usually based on your actual abilities.
That’s why you can believe “I can definitely do it” and tackle difficult challenges.
However, sometimes you might think “There’s no need to listen to others’ opinions.”
As a result, you might miss advice that would actually be helpful.
In other words, your confidence and curiosity are your greatest weapons, but a sense of balance is important.

Characteristic ③”Prioritizing Intellectual Curiosity over Ethics”

When told “This research seems interesting but what about ethically?”, have you ever thought “But I want to know” in your heart?
For people with INTP-AD, the pursuit of truth is more attractive than anything else.
You probably have the belief that “Understanding comes first, before good and evil.”
This attitude leads to innovative discoveries that transcend existing frameworks.
However, you may be misunderstood by others as a “cold person” or “lacking consideration.”

Your intellectual curiosity probably works like this:

• Questioning existing concepts with “Why does such common sense exist?”
• Constructing new frameworks with “What about this theory?”
• Unconventional problem-solving with “Normally we do it this way, but there are other methods too”

For you, acquiring knowledge might be life’s greatest joy.
However, this attitude can give the impression of being “someone who doesn’t care about people’s feelings.”
In reality, you’re not cold-hearted, your interests are just directed differently.
Therefore, it’s important to find a balance between intellectual pursuit and consideration for others.
In other words, your intellectual curiosity is a wonderful characteristic, but harmony with those around you is also important.

Strengths and Weaknesses of INTP-AD

Strengths of INTP-AD

When you think “This problem looks interesting,” aren’t you the type who can think it through to the end even when others give up?
That’s exactly INTP-AD’s greatest weapon.
When you find complex problems, you analyze them logically like solving a puzzle.
And you can confidently propose innovative solutions that no one else thinks of.
This characteristic truly shines in projects requiring innovation and cutting-edge research.

The wonderful strengths you possess:

• Creative problem-solving with “There’s a completely different approach from previous methods”
• Calm and logical analytical ability with “The data makes the answer clear”
• Strong confidence and decisiveness that believes “I can definitely do it”

You find new paths without being bound by common sense.
This ability is particularly valuable in unknown fields like AI technology and space development.
Furthermore, you have the mental strength to approach difficult situations positively, thinking “It will work out somehow.”
Your insatiable curiosity for knowledge will continue to help you grow throughout your life.
In other words, you have the strongest combination of creativity and logic.

Weaknesses of INTP-AD

“I only said what was logically correct, so why is everyone in a bad mood?” Have you ever been puzzled by this experience?
That might be the moment when your shortcomings showed.
While you are intellectually brilliant, you tend to struggle with reading others’ emotions.
Also, your confidence that “my ideas are the best” sometimes intimidates those around you.
Furthermore, your attitude of “as long as it’s interesting, that’s fine” can lead to results that lack social consideration.

Shortcomings you should be mindful of:

• Dismissing emotions, being told “the logic is correct, but…”
• Arrogant attitude that makes people think “that person is always condescending”
• Lack of ethical awareness that gets you told “isn’t that a bit inconsiderate?”

You might think “there’s no problem because I’m saying the right thing.”
However, even correct arguments can hurt others depending on how they’re delivered.
Also, the conviction that “I am right” can cause you to miss valuable advice.
These characteristics make long-term relationships and teamwork difficult.
In other words, consideration for others is the key to leveraging your intellectual strengths.

FAQや注意点

HAXACOの結果と、16personalities（通称MBTI診断）やMBTI（本家）と結果が変わる

1. 性格は遺伝と環境の影響を受けるため、環境が変われば回答も変わります（例、疲れてると情動性が変化するなど）。遺伝について詳しくはこちら。
2. 年齢次第で回答のブレがあります。詳しくはこちら。
3. タイプ分類は各数値が3以上、3未満で行っているため、3に近い値だと、質問の聞き方やその時の環境次第で結果が変わりやすくなります。タイプよりも数値を見てください。
4. MBTI（本家）や16personalities（通称MBTI診断）は質問設計の段階でどの程度統計的な処理をしているか論文が見当たらないため不明確です。一方で、ビッグファイブやHEXACOはそういった論文が簡単に見つかりますし、今回のHEXACO-JP診断は論文ベースです。
5. MBTIや16personalitiesは普段の行動（学力・年収など）や、脳・遺伝などとの比較した研究論文があまり多くない一方で、ビッグファイブやHEXACOは数多く存在します。
6. そもそもHEXACOはビッグファイブの要素の変形なので似て非なるものです。HEXACOの正直・謙虚さは、ビッグファイブの協調性と神経症傾向から抽出されています。下記「補足」参考。

その他にもご質問があれば運営者のトキワ（@etokiwa999）までご連絡ください。

性格診断の結果はあくまで人生の「ヒント」まで

先にも書きましたが、性格は遺伝と環境の影響を受けます。遺伝の影響で、ブレ幅は一定ですが、環境次第である程度答えがブレます。

またビッグファイブやHEXACOの研究論文では学力や年収などと相関分析をしていますが、自然科学の実験ほど大きな相関係数ではありません。相関係数は最小-1、最大1ですが、だいたい-0.4～0.4ほどが多いです。もちろん高いものもあります。0.8や0.9ではなく、それに比べたら低いです。

ただそれでも様々な研究はありますので、「占い以上、自然科学未満」と思ってください。心理学や占いを100％否定しているわけではありません。

補足

16personalities（通称MBTI診断）の概要

16personalities（16タイプ性格診断）は、MBTI（Myers-Briggs Type Indicator）とビッグファイブをベースにして作られています。

厳密には16personalitiesとMBTIは別物なのです。

MBTIは、ユングの心理学的類型論を基に開発された性格診断ツールです。

16personalitiesはMBTIの4つの指標（E外向-I内向、S感覚-N直観、T思考-F感情、J判断-P知覚）を採用しつつ、アイデンティティ（AとT）という指標の追加、独自の質問項目・評価基準を設けています。

この性格診断の良いところとしては、韓国アイドルが広めたり、恋愛マッチングアプリでも使われたりするなど、とても有名で、回答数がとても多いことにあります。それを利用して分析して論文として公開すれば信頼性は高いかもしれません。

ただし、悪いところとしては、科学的な裏付けが弱いところがあります。査読付き論文の数が少ない、統計処理の方法が不明確、性格と学力・収入・脳機能・遺伝的要因などとの関連性について十分な根拠が提示されていない、などが理由です。

16personalitiesとは？科学的根拠やMBTIとの違いを解説

MBTI（本家）の概要

MBTIは性格を16タイプに分類する心理学の理論です。

そもそもMBTIとは、マイヤーズ・ブリッグス・タイプ・インジケーター（Myers-Briggs Type Indicator）の略称です。

MBTIでは、以下の4つの指標を組み合わせて性格を16タイプに分類します。

• 外向性（Extraversion）か内向性（Introversion）
• 感覚（Sensing）か直観（iNtuition）
• 思考（Thinking）か感情（Feeling）
• 判断（Judging）か知覚（Perceiving）

つまり、MBTIでは自分の性格傾向を「ISTJ」や「ENFP」などの4文字で表現するのです。

16personalitiesよりは論文は存在しますが、ビッグファイブやHEXACOほど頑健な研究結果が出ているわけではありません。

MBTIとは？16タイプ性格紹介(恋愛や仕事)・科学的根拠を解説

ビッグファイブの概要

性格心理学において最も有力な特性理論の一つが「ビッグファイブ（Big Five）」です。

ビッグファイブは、開放性、誠実性、外向性、協調性、神経症傾向の5つの特性を測定します。

また、16personalitiesやMBTIはタイプ分類（例、外向的か内向的かのどちらか）を用いるのに対して、ビッグファイブが特性を連続的な数値で評価する（例、外向性3.5）点も大きな違いです。

さらに、古くから研究されており、論文数も多く、学力や所得、脳や遺伝など、他の分野でも多くの研究が行われています。ビッグファイブの方が比較的、科学的な裏付けが強いと言えます。

MBTI・ビッグファイブ・HEXACOの相関関係

MBTIの4指標とビッグファイブの5因子には相関関係があります。

この相関を示した代表的な研究に、「The relationship between the revised NEO-Personality Inventory and the Myers-Briggs Type Indicator」という論文があります。

また、MBTI（本家）とビッグファイブを参考にして作られた16personalities（通称MBTI診断）では、ビッグファイブの神経症傾向が「アイデンティティ」と呼ばれており、自信（Assertive）か、慎重（Turbulent）かで分類されています。

これらの関係をまとめたのが以下の図です。

一番右には、比較的新しい性格診断である「HEXACO（ヘキサコ）」があります。ビッグファイブに1つ指標「正直・謙虚さ」を加えて改良され、ダーク特性（倫理観）が分かるようになりました。

今回のHEXACO-JP性格診断では16personalitiesの5文字に加えて、ダークD/ライトLを付けてより詳細に分析できるようにしています。
