ESFJ-TD (Consul Anxious Dark) Love & Work Guide

Have you ever felt like you wanted to consider things more carefully while everyone in a meeting was rushing to conclusions?
Can you relate to the experience of being unable to express your own opinions because you’re too focused on reading other people’s feelings?

If this sounds like you, you might be an ESFJ-TD type.
Your compassion for others runs so deep that sometimes you lose sight of yourself…
But this is definitely not a weakness.

In this article, we’ll explain in detail the characteristics of ESFJ-TD and their tendencies in love and work.
We’ll empathize with the feelings deep in your heart and share hints for living a better life.

Overview of HEXACO

What is HEXACO

There’s a new approach called “HEXACO” that understands personality through six dimensions.
It reflects your true self better than traditional models.
The six letters H-E-X-A-C-O each represent different aspects of personality.

Specifically, these elements include:

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

You might find answers to the question “Why do I feel this way?”
The new element of “Honesty-Humility” in particular helps explain complex feelings in relationships.
You’ll experience a sensation like obtaining a map of your heart.

What is ESFJ-T (Consul – Turbulent)?

Perhaps you’re someone who sensitively notices changes in people’s facial expressions?
You might have the natural inclination to lend a helping hand when someone is in trouble.
But at the same time, don’t you often worry, “Is my judgment correct?”

• Strong empathy and other-oriented nature
• Sensitivity to social evaluation
• Practical support skills
• Self-doubt and perfectionism
• Pursuit of harmony and stability

In your heart, you are constantly thinking “Is there something I can do for others?”
On the other hand, you must also be harboring anxiety about “What if I can’t meet their expectations?”
This sensitive heart is precisely your greatest strength.

ESFJ-T (Consul-Turbulent) Explained Scientifically

Characteristics of ESFJ-TD

Characteristic ①”Excessive Focus on Sense of Duty and Social Status”

I understand well your feeling of constantly thinking “I must meet everyone’s expectations.”
When you hesitated about whether to give up your seat on the train, haven’t you worried about the gazes around you?
Even when you come up with new ideas at work, you hesitate thinking “Is it okay to say something like this?”

For you, other people’s evaluations carry more weight than just mere opinions.
This is not necessarily a bad thing.
Your attitude of valuing social rules is also a source of trust from those around you.

The following are behavioral patterns commonly seen in you:

• Valuing social norms and traditions
• Hiding your true feelings due to concern about others’ eyes
• Working excessively hard to gain approval from those around you

But sometimes, please also value your own feelings.
By balancing the expectations of those around you with your true feelings, you can be more naturally yourself.
Even if you’re not perfect, you are already a sufficiently valuable person.

Characteristic ②”Hypersensitivity to Criticism and Low Self-Esteem”

Don’t you have moments when the anxiety “Maybe I said something wrong again” crosses your mind?
A single word from your boss stays in your head and you keep thinking about it until late at night…
Just because someone’s email reply is late, you worry “Maybe they hate me now”…

These emotions are also expressions of your kindness and sense of responsibility.
Because you take words from others seriously, you get deeply hurt.
But by the same token, your ability to understand people’s feelings should be exceptionally strong.

The characteristics commonly seen in you are as follows:

• Hesitating to challenge new things for fear of criticism
• Prioritizing others’ opinions over your own
• Excessively fearing failure and easily falling into perfectionism

Criticism sometimes becomes a seed for growth.
Not all criticism determines your worth.
The warmth and compassion you possess are beautiful qualities that no one can deny.

Characteristic ③”Excessive Dependence on Others and Self-Sacrifice”

When friends come to you for advice, don’t you want to help them even if it means putting your own matters aside?
Even in situations where you want to say “no,” you can’t refuse when you see the other person’s troubled face…
You often find that you have almost no time left for yourself.

You feel deep joy in being needed by others.
But at the same time, you also have a side that becomes anxious when you’re not acknowledged.
This is not weakness at all, but proof that you value connections with people.

The behavioral patterns commonly seen in you are as follows:

• Sparing no time or effort to meet others’ expectations
• Becoming too enthusiastic about solving other people’s problems, neglecting your own life
• Suppressing your own opinions and emotions to maintain relationships

But please remember:
You yourself are also a being who deserves to be valued.
Sometimes prioritizing your own feelings is also necessary for healthy relationships.

Lying in bed at night thinking “Was that comment I made today okay?”…
Haven’t you had experiences where you were too scared to jump into new environments and missed opportunities?

What you think are your weaknesses are actually the flip side of your rich sensitivity.
Being prone to anxiety is because you care so much about those around you.
Fearing change is because you have feelings of not wanting to break current relationships.

Even if you’re not perfect, you are already loved by many people.

Compatible Types for ESFJ-TD

Compatible Types: People with S

Don’t you feel a deep connection with realistic, grounded people?
Relationships where you feel “This person is trustworthy” and feel at ease together…
Bonds where you understand each other’s efforts and thoughtful considerations…
Such stable connections are what you can build with S-type people.

You’ll likely feel a sense of “mutual understanding” especially with ISTJ and ISFJ people.
You can share values that emphasize strong responsibility and cherish traditions and promises.
With ESTJ as well, you should often find common ground in your shared feelings about valuing organizations.

The reasons for good compatibility with S-types are as follows:

• You can share practical problem-solving approaches
• You’re likely to align on values that respect tradition and order
• Both have high attention to detail and can understand each other’s efforts

However, sometimes your mutual perfectionism can clash.
Being too similar in thinking can make it difficult to generate new perspectives.
The difference between T-types and F-types may create emotional temperature differences.
Even so, this is a compatibility where basic trust relationships are easy to build.

Compatible Types: People with D Included

Don’t you sometimes have reliable people who make you think “I’ll be okay if I follow them”?
People who show you clear direction when you’re lost…

With extroverted D-types like ENTJ and ESTJ, role division works well.
When their vision combines with your execution ability, wonderful results are born.

The reasons for good compatibility with D-types are as follows:

• D-type vision and ESFJ-TD execution ability complement each other
• D-type decisiveness and ESFJ-TD attention to detail create balance
• Each other’s different perspectives generate new ideas and solutions

However, you may sometimes be hurt by D-types’ direct expressions.
Their adaptability to change might feel a bit too fast for you at times.
You might feel anxious about D-types’ fearless attitude toward risk.
But if you can understand each other’s differences, it becomes a very growth-promoting relationship.

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。
