Overview of HEXACO

What is HEXACO

“Human personality is actually more complex than we think, isn’t it?” Have you ever felt this way?
That intuition is correct.
The relatively new personality model “HEXACO” provides the answer.
It allows us to understand human personality more deeply through six elements.

The six elements of HEXACO are as follows:

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

The revolutionary aspect of this model is the new element of “Honesty-Humility.”
Parts that weren’t visible in the traditional Big Five become clear.
It’s like a blurry photo suddenly becoming sharp.
Your complex personality should be understood more accurately as well.

These are connected like 16personalities to express types. Now let’s introduce the various types!

What is INTP-T (Logician・Cautious Type)?

INTP-T is a type with low extraversion (I), high openness (N), low agreeableness (T), low conscientiousness (P), and high neuroticism (T) in the Big Five. Characteristics:

• High intellectual curiosity and analytical ability
• Self-doubt and perfectionism
• Creative and innovative thinking
• Anxiety about social interactions
• Strong desire for continuous self-improvement

They enjoy solving complex problems, but tend to underestimate their own abilities. While they explore new ideas, they may hesitate to put them into action.

In interpersonal relationships, they seek deep intellectual connections but tend to feel stressed in social situations. They have a tendency to fear failure, but this also becomes a driving force for their growth.

INTP-T (Logician-Turbulent) Scientific Analysis with 30+ Papers

For you as an INTP-TD, understanding things logically is as natural as breathing.
When you approach problems like solving complex puzzles, you feel genuinely enjoyable.
But sometimes, you may feel anxious wondering “Is this really correct?”

Your thinking characteristics are as follows:

• Preference for abstract concepts
• Building original theories

For someone like you, it’s important to trust your thinking ability more.
At the same time, don’t forget to maintain consideration for those around you.
The balance between logic and humanity brings out your true strengths.

Characteristic ②: “Valuing Independence and Freedom”

“Why do I have to do things the same way as everyone else?” Have you ever thought this?
For you as an INTP-TD, the freedom to act as yourself is more precious than anything else.
When someone tells you “do it this way,” you probably want to rebel.
That’s because you have a strong will to walk your own path.

Your independence manifests in these ways:

• Solving problems with your own methods
• Not easily influenced by others’ opinions
• Proceeding with things at your own pace

While maintaining your authenticity, cherish connections with trustworthy people.
Balanced relationships will enrich your life even more.

“They say it’s common sense, but is that really correct?” Have you ever had such doubts?
You as an INTP-TD are a valuable person who doesn’t take existing rules and values for granted.
When everyone accepts something as “just the way things are,” you can pause and say “wait a minute.”
This perspective is the source of groundbreaking ideas.

Your innovative thinking appears in these ways:

• Ideas not bound by existing frameworks
• Problem-solving beyond ethical constraints
• Building new theories that overturn common sense

However, this characteristic may sometimes create friction with your surroundings.
You may have been hurt by being told “you shouldn’t think about such things.”
Also, there must be times when you can’t be confident in your thoughts, wondering “Is this really okay?”

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。

ビッグファイブ(Big Five)診断とは？概要・遺伝・MBTIとの関連

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。
