While drawing an ideal world, you often blame yourself, thinking “I’m a worthless person.”

You can understand your friends’ troubles as clearly as if they were in your palm, yet controlling your own emotions is an extremely difficult task.
You probably recognize this contradictory feeling.

People with this personality type have the talent to shine in creative work, but it’s not uncommon to struggle with reconciling with the real world.
But don’t worry.

※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” is a new model that measures human personality along six dimensions.
It can analyze personality in more detail than conventional psychological models.
The six letters H, E, X, A, C, O each represent important aspects of personality.

Specifically, it consists of the following elements:

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

The innovative point of this model is the addition of a new element called “Honesty-Humility.”
This has made it possible to understand human personality more three-dimensionally.
Your own personality patterns will also become visible through this combination of six elements.

  • Low → Dark (D: Dark)
• E: Emotionality
  • High → Turbulent type (T: Turbulence)

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

What is INFP-T (Mediator・Turbulent type)?

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

• Strong idealism and sensitivity
• Self-doubt and perfectionism
• Creative self-expression
• Sensitivity to others’ opinions
• Internal conflict and desire for growth

They possess rich imagination and deep emotions, feeling a strong sense of mission to make the world a better place. However, they often feel anxious about their abilities and decisions.

In interpersonal relationships, they seek genuine connections but are sensitive to criticism and rejection from others. They tend to feel stressed by change and uncertainty, but this also becomes the driving force that promotes self-understanding and growth.

INFP-T (Mediator-Turbulent) Explained with 20+ Studies

Characteristics of INFP-TD

Characteristic 1: “The Inner Battle of an Idealist”

Have you ever dreamed of a perfect world while whispering “I’m nothing…” in your heart?
INFP-TD individuals envision ideals like an artist painting a beautiful picture.

But at the same time, they are also their harshest critics.
They offer kind words to others, yet pass merciless judgment on themselves.
You may be carrying such contradictions.

This inner battle can manifest in the following ways:

• Even when wonderful ideas come up, giving up thinking “it won’t work anyway”
• Accepting others’ mistakes as “unavoidable” while being unable to forgive one’s own
• Being caught between the ideal self and the real self

Actually, this characteristic is also a “misunderstood strength.”
It’s precisely because you have high ideals that you can create works that move people and generate deep empathy.
The pursuit of perfection can be said to be the source of uncompromising beauty.

Characteristic 2: “Seismograph-like Sensitivity of the Heart”

Have you ever worried “Did I say something wrong?” just because a friend’s expression clouded slightly?
INFP-TD individuals sensitively detect changes in surrounding emotions like a seismograph of the heart.

While they can feel others’ pain as their own, this overly rich sensitivity can sometimes become a burden.
Have you had experiences of crying uncontrollably while watching a movie, or feeling depressed all day after watching the news?

This emotional characteristic can manifest in the following ways:

• Never missing even subtle changes in others’ emotions
• Having intense emotional waves and struggling with control
• Critical words piercing deeply into the heart

But think about it.
It’s precisely because of this characteristic that you are a precious being who can empathize with people’s hearts.
If you learn emotional control methods, you’ll be able to make the most of this “superpower.”

Characteristic 3: “A Creator Lost in the Ocean of Possibilities”

Do you ever find yourself lost in thought, wondering “Which should I start with?” when ideas keep flowing in your mind?
INFP-TD individuals envision infinite possibilities like an explorer before a treasure mountain.

However, there are too many choices to decide.
In pursuit of perfection, they can’t take a single step forward.
You’ve probably felt such dilemmas.

This creativity and hesitation can manifest in the following ways:

• Coming up with innovative ideas one after another
• Taking a long time to make important decisions
• Postponing action thinking “there must be a better way”

Actually, this indecisiveness is also a manifestation of “careful perfectionism.”
If you develop appropriate decision-making skills, your creativity should shine even brighter.
Getting lost in the ocean of possibilities is also the first step toward new discoveries.

Strengths and Weaknesses of INFP-TD

Strengths of INFP-TD

Your heart is a special place where creative ideas spring forth like a magical fountain.

Weaknesses of INFP-TD

Do you ever find yourself caught in a storm of emotions, losing sight of who you are?
A challenge that INFP-TD individuals tend to face is being easily overwhelmed by emotional waves.

Even minor criticism can cut deep into your heart, or when faced with decisions, you might postpone them thinking “I want to think about it a little more.”
You’ve probably experienced moments of feeling down, wondering “Why am I so hopeless?”

The difficulties that INFP-TD individuals tend to face include:

• Intense emotional fluctuations that are difficult to stabilize
• Avoiding important choices and missing opportunities
• Tendency to escape reality and avoid facing problems

Additionally, you may be extremely harsh on yourself, falling into the belief that “I’m a worthless person.”
This self-critical voice can hinder you from showcasing your true talents.
You also tend to struggle between ideals and reality, experiencing frustration easily.

But please rest assured.
These “weaknesses” are actually the flip side of your rich sensitivity and high ideals.
With the right coping strategies, these are challenges you can definitely overcome.

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。
