Key Takeaways
- The Thinking-Feeling divide dominates decision-making. Nearly 96% of INTJs chose the head over the heart, while 75% of ENFPs chose the heart. Not a single Thinking type had more than 15% of respondents choosing the heart, making the Nature trait the strongest predictor in this survey.
- Masking sadness is nearly universal across all types. Even the lowest-scoring personality type (ISTPs at 68%) still had a clear majority who admit to hiding sadness behind a smile. The 14-point gap between the highest and lowest types was the smallest of any question in the survey.
- Thinking types and Feeling types clash most over arguments. When debating someone who’s talking nonsense, just 10% of ESTPs said they’d take care not to make the other person feel stupid, compared to 58% of INFJs. This nearly 50-point gap highlights one of the deepest divides in how personality types handle conflict.
- Emotional expression depends on both Energy and Nature traits. Extraverted Feeling types were far more likely to talk about their feelings, cry in front of others, and visibly show excitement. Introverted Thinking types scored lowest on all three measures, often by margins exceeding 50 percentage points.
- The Prospecting trait tempers confidence in pure rationality. Among Thinking types, those with the Prospecting trait were noticeably less likely to say their decisions always have clear rational reasons. INTPs agreed at 60%, well below the 84% of their Judging counterparts, INTJs.
Introduction
The tension between logic and emotion is one of the oldest debates in human experience. Should we follow our heads or our hearts when making important choices? Most people lean one way or the other, but just how strongly personality shapes that leaning may come as a surprise.
We surveyed over 31,000 respondents on questions ranging from decision-making style and sentimentality to emotional expression and vulnerability. The results paint a detailed picture of how different personality types experience and express their inner emotional lives – and where they draw the line between reason and feeling.
As expected, the Thinking and Feeling traits emerged as the primary dividing line on most questions. But the data also revealed some surprises, including one emotional behavior that nearly every personality type shares and telling differences that go well beyond the Nature trait alone.
A note on this survey: Our respondents are people who visited our website – not a balanced mix of the wider population. All results are self-reported, and personality is just one of many factors (alongside age, culture, and more) that shape responses. Think of what follows as a starting point for reflection, not a scientific conclusion.
Heart vs. Head: The Personality Divide
Agreement with "Do you mostly listen to your heart or your head when it comes to making important choices?"
Few survey questions produced as clear a divide as this one. The split falls squarely along the Thinking and Feeling personality traits, with Thinking types overwhelmingly choosing the head. INTJ personalities (Architects) led the way at nearly 96%, and ISTJ personalities (Logisticians) were close behind. On the other side of the divide, ENFP personalities (Campaigners) chose the heart at a rate of 75%, with INFP personalities (Mediators) at 71%.
The divide wasn’t entirely seamless, however. ISFJ personalities (Defenders) were the only Feeling type to lean slightly toward the head, at 52% – likely a reflection of their practical, duty-oriented nature. On the Thinking side, the consensus was strikingly uniform: not a single Thinking type had more than 15% of respondents choosing the heart. For these types, rational analysis doesn’t just play a role in decision-making – it dominates it.
Sentimental Keepsakes and Personality Types
Agreement with "Are there many things in your room that hold special sentimental value for you?"
Sentimental attachment to personal belongings appears to be a hallmark of Diplomat personality types. All four – INFPs, ENFPs, INFJ personalities (Advocates), and ENFJ personalities (Protagonists) – agreed at rates above 79%, with INFPs leading at 82%. These Intuitive, Feeling types tend to assign deep meaning to the objects around them, turning everyday items into emotional touchstones.
Analyst types, by contrast, were far less likely to fill their spaces with sentimental objects. INTP personalities (Logicians) and ENTP personalities (Debaters) both hovered around 48%, and INTJs were even lower at 43%. The Feeling trait, rather than the Intuitive trait, appears to be the key driver – Feeling types across all Roles consistently outscored their Thinking counterparts, making sentimentality one of the clearest markers of this trait in everyday life.
Sparing Feelings in Heated Arguments
Agreement with "When in a heated argument with someone who’s talking nonsense, do you take care to not make them feel stupid?"
This question revealed one of the starkest contrasts in the entire survey. ESTP personalities (Entrepreneurs) were the least likely to worry about making someone feel stupid during a heated argument – just under 10% said they would take care to avoid it. ENTPs were barely more diplomatic at 11%, and ENTJ personalities (Commanders) came in at 15%. For these Thinking types, if someone is talking nonsense, sparing their feelings isn’t a priority.
Feeling types told a very different story. INFJs led the way at 58%, followed closely by ENFJs and ISFJs. Even in the heat of an argument, these personality types appear to weigh the other person’s dignity alongside the substance of the debate. The nearly 50-point gap between the most compassionate Feeling types and the most direct Thinking types is one of the largest in this survey, showing just how differently the Nature trait shapes interpersonal conflict.
Masking Sadness Behind a Smile
Agreement with "When feeling sad, do you still put on a smile because you don’t want people to know how you feel?"
Unlike many other items in this survey, masking sadness behind a smile produced surprisingly little variation across all personality types. INFJs topped the list at 82%, with INFPs close behind at 81%, but even the lowest-scoring type – ISTP personalities (Virtuosos) at 68% – still had a clear majority agreeing. The gap between the highest and lowest types was a mere 14 percentage points.
This near-universal tendency is notable given how divided these same types were on every other emotional question. People who insist they listen to their heads and people who proudly follow their hearts both admit to the same behavior: hiding their true feelings behind a pleasant expression. It suggests that concealing sadness is less about personality and more about broader social norms – the unspoken rule that we should appear fine, even when we aren’t.
Which Personalities Struggle with Emotional People?
Agreement with "Do you often find it difficult to relate to people who let their emotions guide them?"
The Thinking trait reasserts itself powerfully here. A striking 85% of INTJs said they often find it difficult to relate to people who let emotions guide them, and ISTPs, INTPs, and ISTJs all exceeded 80%. For types that prize logic and objectivity, watching others make decisions based on feelings can be genuinely puzzling – not necessarily out of judgment, but out of a fundamental difference in how they process the world.
ENFPs, naturally, saw things very differently – they were the least likely to report this difficulty, at just 15%, with INFPs at 18% and ESFP personalities (Entertainers) at 21%. For these types, emotional decision-making isn’t something to relate to – it’s simply how they operate. The 70-point gap between INTJs and ENFPs on this question stands as one of the most dramatic in the entire survey.
Rational Reasons Behind Every Decision
Agreement with "Do your actions and decisions always have clear and rational reasons behind them?"
Personality types that combine the Thinking and Judging traits stood apart on this question. INTJs led at 84%, and the other Thinking-Judging types – ENTJs, ISTJs, and ESTJ personalities (Executives) – all landed above 73%. These types share a strong confidence that their actions are driven by logic and careful reasoning, consistent with their broader approach to life.
At the other end, Feeling types with the Prospecting trait were the least likely to agree. INFPs came in at just 24%, and ISFP personalities (Adventurers) at 31%. Even among Thinking types, the Prospecting trait made a noticeable difference: INTPs landed at 60%, well below their Judging counterpart INTJs. This suggests that the Prospecting trait’s openness to spontaneity tempers the confidence some types have in the pure rationality of their own decisions.
Honesty vs. Sensitivity Across Personality Types
Agreement with "Would you tell the truth even if you knew the other person would be offended by it?"
Would you deliver an uncomfortable truth, even knowing it would hurt? For Thinking types, the answer was a resounding yes. ENTPs led at nearly 84%, with ENTJs, INTJs, ESTPs, and ESTJs all surpassing 79%. These personality types tend to view honesty as a matter of principle – softening the truth to spare someone’s feelings can feel, to them, like a form of dishonesty itself.
For Feeling types, the answer was more complicated. INFPs were the least likely to deliver a potentially hurtful truth, though 43% still said they would – meaning that even among the most sensitive types, nearly half chose honesty. ESFJ personalities (Consuls) landed at 55%, and ENFJs at 63%. This range within Feeling types suggests a real internal tension: they value both truthfulness and harmony, and when those values collide, the outcome is anything but predictable.
Who Talks Openly About Their Emotions?
Agreement with "Do you often talk about your own feelings and emotions?"
Two traits converge powerfully on this question: Extraverted and Feeling. All four Extraverted Feeling personality types exceeded 60%, with ENFPs leading at 67%. These types not only experience emotions deeply but also feel a natural pull to share them with others – talking about feelings is less a chore for them than a way to build connection and understanding.
Introverted Thinking types, by contrast, were strikingly reluctant to discuss their emotions. INTJs and ISTPs both came in around 12%, and none of the Introverted Thinking types exceeded 16%. The combination of drawing energy from within and preferring logic over feelings creates personality types that tend to process emotions privately – if they address them openly at all. The gap between the most and least expressive types here exceeds 50 percentage points.
Crying in Front of Others
Agreement with "Would you let yourself cry in front of others?"
Willingness to cry in front of others may be one of the most revealing measures of emotional openness – and it divided personality types dramatically. ESFJs were the most willing at 61%, with ENFPs and ENFJs both above 55%. For these Extraverted Feeling types, vulnerability in the presence of others is not something to suppress but a natural extension of emotional expression.
INTJs and ISTPs were the least willing, both at around 12%, with INTPs only slightly more open at 14%. Even among Feeling types, Introversion made a noticeable difference – INFPs, despite their deep emotional nature, agreed at just 38%. This suggests that the Energy trait plays nearly as large a role as the Nature trait in determining whether someone will let themselves cry when others are watching.
How Personalities Show Their Excitement
Agreement with "In your opinion, is it easy for other people to tell when you’re excited?"
When it comes to visible excitement, Extraverted Feeling types were nearly unanimous. Over 89% of ENFPs, ENFJs, ESFPs, and ESFJs agreed that others can easily tell when they’re excited, with ENFPs at the very top at 92%. For these personality types, enthusiasm is an energy that radiates outward – and they’re well aware of it.
INTJs stood out as the only type where fewer than half – just 47% – believed their excitement was easy for others to detect. Other Introverted types scored higher but still trailed their Extraverted counterparts considerably. The primary driver here is the Energy trait, but the Feeling trait amplifies the effect as well – ENTPs, for instance, came in at 80%, still a full 12 points below ENFPs despite sharing three of their four core traits. How much of our excitement the world gets to see depends heavily on how outgoing and emotionally expressive we naturally are.
Open Affection Divides Personality Types
Agreement with "Do you enjoy openly showing your affection for people you care about?"
ENFJs were the most enthusiastic about openly showing affection, with 92% agreeing that they enjoy it. ENFPs were nearly as high at 90%, while ESFJs topped 89% and ESFPs came in near 87%. The common thread is unmistakable: all four are Extraverted Feeling types who naturally channel their emotions outward. For these personalities, showing affection isn’t just something they tolerate – it’s something they actively enjoy and seek out.
INTJs sat at the opposite end, with just 38% agreeing – followed closely by ISTPs at the same level and INTPs at 40%. Both the Energy and Nature traits appear to influence this question. ENTJs, for instance, came in at 66%, nearly 28 points above their Introverted counterpart INTJs despite sharing three core traits. Likewise, INFPs agreed at 75%, well above INTPs. The pattern is consistent: Introversion pulls the numbers down, and the Thinking trait pulls them down further. When both traits combine, they create types that may care deeply about the people in their lives but prefer to show it quietly – or simply don’t feel the urge to put it on display.
Conclusion
Across nearly every question in this survey, the Thinking and Feeling traits served as the clearest predictor of how people relate to emotion. Thinking types consistently prioritized logic, honesty, and emotional restraint, while Feeling types leaned toward empathy, sentimentality, and open expression. The gaps were sometimes staggering – exceeding 70 percentage points between the most and least emotionally driven personality types.
Yet the data also revealed important nuances. Masking sadness, for instance, was nearly universal, suggesting that social pressure to appear fine cuts across all personality lines. The Energy trait shaped how visibly people expressed their emotions, and the Prospecting trait tempered even Thinking types’ confidence in the pure rationality of their own decisions. No single trait tells the whole story.
Perhaps the most telling insight is that these patterns describe tendencies, not absolutes. Even the most logic-driven INTJs sometimes follow their hearts, and even the most heart-led ENFPs sometimes choose reason over feeling. The head and the heart are not opposing forces so much as two instruments that every personality type uses – just in very different proportions.
