Overview of HEXACO

What is HEXACO

“HEXACO” is gaining attention as a new method for understanding personality.
This is a model that represents human personality through six elements.
The name comes from the six letters H・E・X・A・C・O.
Each letter represents a different aspect of personality.

Specifically, it consists of the following elements:

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

The excellent point of this model is that it allows for more detailed personality analysis.
A new perspective called “Honesty-Humility” has been added to the traditional Big Five model.
This element makes it possible to measure human integrity and humility more accurately.
It will serve as a clue to understanding your personality more deeply.

64 Classifications by HEXACO

Based on whether each of the six elements is high or low, there are 64 types in total. The specific classification is as follows.

• H: Honesty-Humility
  • High → Light (L: Light)
  • Low → Dark (D: Dark)
• E: Emotionality
  • High → Turbulent (T: Turbulence)
  • Low → Assertive (A: Assertiveness)

  • Low → Introvert (I: Introvert)
• A: Agreeableness
  • High → Feeling (F: Feeling)

• C: Conscientiousness
  • High → (J: Judging)
  • Low → (P: Prospecting)
• O: Openness
  • High → Intuitive (N: iNtuitive)
  • Low → Sensor (S: Sensor)

These are combined like 16personalities to express them as one type. Now let’s take a detailed look at each type!

What is ISFP-T (Adventurer・Cautious Type)?

ISFP-T is a type with low extraversion (I), low openness (S), high agreeableness (F), low conscientiousness (P), and high emotionality (T). Characteristics:

• High sensitivity and creativity
• Self-doubt and perfectionism
• Deep empathy for others
• Sensitivity to social evaluation
• Internal conflict and self-exploration

They possess rich sensitivity and creativity, cherishing the present moment, but may also feel anxious about their abilities and decisions.

They learn through practical experience, but fear of failure sometimes makes them hesitant to express themselves. In interpersonal relationships, they seek deep empathy and harmony, but are sensitive to criticism and rejection from others.

They are open to change and new experiences, but tend to feel stressed by uncertainty. This internal conflict becomes the driving force for continuous self-understanding and growth.

Characteristics of ISFP-TL

Characteristic ①「Sensitive and Introspective Artist Soul」

Have you ever stopped in your tracks while walking through the city, captivated by the beauty of a sunset?

ISFP-TL individuals have a delicate sensitivity that allows them to be enchanted by such everyday beauty.
They find special meaning in the warm lighting of cafes and the rhythm of raindrops.
Your mind might constantly be swirling with creative ideas.

But when expressing those wonderful ideas, you might hesitate, thinking “Maybe no one will understand this.”

Your artist soul manifests in the following ways:

• Creating new worlds through rich imagination
• Sensing the world through all five senses
• Possessing a unique aesthetic sense

Above all, you have a strong desire to “be true to yourself.”
Even when you sometimes lack confidence in your expression, that very sensitivity is your charm.
You have the talent to listen to your inner voice and express your unique worldview.

Characteristic ②「Strong Ethics and Emphasis on Fairness」

Have you ever experienced heartache when seeing someone being treated unfairly at work?

As an ISFP-TL, you must strongly feel “this is wrong” in such situations.
Even if it doesn’t directly involve you, you feel others’ pain as if it were your own.
The belief that “everyone should be treated fairly” supports your actions.

When listening to a friend’s concerns, you never take a condescending attitude.
You try to genuinely empathize by putting yourself in their position.

Your ethics shine in the following situations:

• Putting the other person’s feelings first
• Disliking lies and falsehood, striving to be honest
• Trying to protect those in vulnerable positions

Also, your feelings of caring for animals and nature are exceptionally strong.
Sometimes you may struggle with the gap between your high ideals and reality.
Even so, that very kindness of yours brings warmth to those around you.

Characteristic ③「Tendency Toward Anxiety and Self-Criticism」

Do you ever find yourself thinking in circles on the way home, wondering “Was what I said strange?” or “What did everyone think?”

As an ISFP-TL, you might often become anxious by reflecting on your words and actions this way.
Even small things that others wouldn’t worry about can feel like major problems to you.
You blame yourself, thinking “I should have done better” or “Why am I so hopeless?”

Even when asked for your opinion in meetings, you hesitate, thinking “What if I say something wrong?”
You become afraid of showing others your imperfect self.

This anxiety tends to manifest in the following ways:

• Procrastinating on important decisions
• Remembering past events at night and feeling depressed
• Feeling nervous when meeting new people

But actually, that very sensitivity is also the source of your creativity.
Because you feel deeply, you can create beautiful things.
If you start by accepting yourself, you’ll surely find your own unique brilliance.

Strengths and Weaknesses of ISFP-TL

Strengths of ISFP-TL

Your greatest charm is the creativity that springs from the depths of your heart and your warm, caring nature toward others.

When a friend is feeling down, you sense their emotions before words are even exchanged.
Before you can say “Are you okay?”, you’re already empathizing with their heart.
Your presence is like a healing light for those around you.

You also have the talent to find beauty in ordinary everyday moments.
You can sense special meaning in the shape of a coffee cup or the movement of clouds.

Your wonderful strengths include:

• Adaptability to flexibly respond to change
• An honest and trustworthy character that can’t tell lies
• A fair heart that wishes for “everyone’s happiness”

Most of all, your way of cherishing “this present moment” is attractive.
You don’t get too bound by plans and try to do your best according to the situation at hand.
Your sensitivity and sincerity surely light a warm flame in the hearts of those around you.

Weaknesses of ISFP-TL

But to be honest, you might have a habit of convincing yourself that “I’m no good.”

Even when choosing from a menu at a restaurant, you keep hesitating, thinking “Is this really the right choice?”
When a friend asks you “Which one is better?”, you can’t decide because you don’t want to trouble them.
And later you might regret it, thinking “I should have chosen the other one after all.”

Even when a colleague gives you just a little criticism, you worry in your heart, thinking “Maybe they hate me now.”
It’s quite difficult for you to accept yourself when you’re not perfect.

Here are things you tend to find challenging:

• Thinking about long-term plans like “Where do you want to be in 5 years?”
• Being satisfied that “this is perfect”
• Saying “I think this way” even when opinions differ

Sometimes you might impose your values on others because you cherish them so much.
But these “weaknesses” are actually misunderstood strengths.
Because you’re sensitive, you can perceive beautiful things, and because you’re careful, you avoid hurting people.

ISFP-TL’s Friendship Tendencies and Improvement Strategies

Friendship Tendencies

For you, time with friends is a special moment where you can truly feel at peace, isn’t it?

When a friend confides their troubles to you, you’re the one who empathizes saying “That must have been hard” before giving advice.
You listen to their stories to the end and never say anything critical.

For your friends’ birthdays, you’d rather give handmade cards than store-bought ones.
You can show your true self to those you trust, thinking “This person will surely understand.”

Your friendships have this kind of beauty:

• Being a trustworthy friend who doesn’t break promises or betray others
• Accepting others’ personalities and values as they are
• Building deep connections through shared hobbies and interests

However, you might become a bit reserved in lively places like parties.
It might take time for you to make friends with new people.
But once you build a friendship, it often becomes something deep that lasts a lifetime.

When Friendships Become Problematic and Solutions

Don’t you often find yourself declining invitations from friends, saying “I’m tired today…” even when they ask you to hang out?

Even though you really want to see them, the anxiety of “What if they think I’m boring?” takes precedence.
And as you continue to decline, you gradually stop getting invited and end up feeling lonely.
When you see your friends having fun with other people, you feel like “I’m the only one being left behind.”

Also, even when there are differences of opinion, you swallow your own thoughts because you “don’t want to be disliked.”
But the frustration continues to linger in your heart.

In such situations, try the following methods:

• Once a month, take the initiative to ask “Want to meet up?”
• Gently express your opinion by saying “I think this way, what do you think?”
• Practice expressing gratitude in words

Your friends don’t view you as critically as you think they do.
Rather, they should be grateful for your kindness and thoughtfulness.
Even if it’s little by little, try to enjoy friendships being your natural self.

Have you ever forgotten you were an adult and become completely absorbed while playing in the sandbox with your child?

When your child is crying, don’t you blame yourself thinking “It might be my fault”?

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。
