In this article, you’ll find comparisons of two personality types — ISTPs and the Enneagram Type 8s — across four important personality domains: Interpersonal/Communication Style, Emotional Style, Intellectual Style, and Organizational Style.
TraitLab collected data about personality traits from thousands of participants who identified as a particular type from the 16 Personality or Enneagram typology.
For each comparison area below, you’ll see show the average similarities and differences between ISTPs and Type 8s. While these comparisons are useful for understanding broad trends across these types, it’s important to remember that all personality types are oversimplifications. For an assessment of your unique personality, you’ll want to use an assessment that goes beyond single personality types.

Your particular style of communicating and interacting with others can be described fairly well by two dimensions: assertiveness and warmth.
Assertiveness describes your tendency to assert yourself, lead, and influence others in social situations, while warmth describes your tendencies to empathize and put others’ needs ahead of your own.
People with the same personality type often share some similarities in assertiveness and warmth. In the graph below, you can see where most ISTPs and most Type 8s fall along both of these dimensions.
First, take a look at where people in each type, on average, fall in this interpersonal space.
ISTPs are forthright, firm, and speak their mind directly. At their best, they are fiercely independent and unaffected by the thoughts and opinions of others. ISTPs may be harsh, frank, or insensitive in their criticism of others. At their worst, they can be overly aggressive and too eager to fight and argue with others.
Type 8s are assertive, competitive, and like a good challenge. At their best, they are bold and confident leaders who are willing to take unpopular action. Type 8s may be overly proud, boisterous, and willing to manipulate others to achieve their goals. At their worst, they can be narcissistic, overly focused on their own needs, and lack empathy for others.
One aspect that ISTPs like you and many Type 8s have in common in your relative comfort around interpersonal conflict and disagreements. Both ISTPs and Type 8s are both likely to focus on their own point of view and goals, even if it leads to some interpersonal tension.
One important difference between you and most Type 8s is in your relative assertiveness or passivity in social situations. Like many ISTPs, you are often on the more passive, reserved side of the spectrum. In some cases, this is a perfect compliment to Type 8s’ more dominant, assertive style, and the two of you can make an effective team. However, you may find that you need to put extra effort into making your opinions heard when working with Type 8s.
Another characteristic of your personality is your emotional style — your tendencies towards different kinds of moods. There are two dimensions that influence emotional style: arousal and valence.
Arousal describes your relative energy level across different situations. Those with high baseline levels of arousal tend to be generally more alert, active, and engaged, while those with a lower baseline are more reserved, subdued, and inhibited.
Valence describes whether these moods tend to be positive (pleasant) or negative (unpleasant). People with a more positively valenced style are more likely to experience emotions like joy, enthusiasm, satisfaction, and serenity. People with a more negatively valenced style are more likely to experience sadness, frustration, dissatisfaction, and anxiety.
The graph below shows where each type, on average, usually sits in this emotional space.
ISTPs tend to be reserved, laid-back, and content. They often see the glass as half-full, confident that things will eventually work out for the best. ISTPs typically respond to challenges with quiet optimism and rarely become overwhelmed when things get difficult. When their efforts fail, they calmly dust themselves off and try again.
Type 8s tend to be energetic and enthusiastic across most situations. They take on new challenges with excitement, confidence, and a sense of adventure. Type 8s are usually more optimistic than most people, and they generally feel like they can handle what life throws at them.
As with most ISTPs, you tend to be more reserved, inhibited, and quiet than most Type 8s. Between the two of you, you are more likely to need more personal space, solitude, and time to decompress. While you can tolerate long periods of calm and quiet, your Type 8 counterparts often craves more engagement and excitement. In the best cases, a Type 8 can pull you out of your comfort zone and get you out into the world, while your quiet nature helps to balance out their intensity.
However, both ISTPs and Type 8s are generally more positive than negative. They are more likely to express enthusiasm, satisfaction, happiness, and other positive emotions across most situations. Like everyone else, they occasionally experience negative emotions like sadness, anxiety, and anger, but they soon return to their usual pleasant state. Together, ISTPs and Type 8s tend to share an optimistic outlook and a resilience to stress.
Your intellectual style describes how you receive, process, and pursue different kinds of information. Differences in intellectual style are captured well by two dimensions: ideas and aesthetics.
Ideas describes your appetite for new information and your interest in complex, challenging material. People high on the ideas dimension have an appreciation for complexity and technical details. People lower on ideas are less interested in learning for learning’s sake, and they prefer to simplify complex topics down to the essential details.
Aesthetics captures your relative interest and sensitivity to aesthetic information and its emotional impact. People higher on the aesthetics dimension usually have strong artistic interests and a deep appreciation for beauty in many forms. Those lower on aesthetics tend to value practical application over artistic merit and usually adhere to more conventional standards of beauty.
In the graph below, you’ll see where ISTPs and Type 8s, on average, fall in this intellectual space.
ISTPs are practical realists. They focus on building practical skills and essential knowledge and are less likely to spend time learning for learning’s sake. In addition, they usually value conventional, tangible accomplishments over artistic expression and rarely feel compelled to develop a creative outlet.
Type 8s are usually highly effective, efficient thinkers, capable of processing large amounts of complex information and distilling it down to its most useful elements. They are pragmatic and grounded and prefer to apply their knowledge to conventional, practical pursuits.
Like most ISTPs, you are less interested in learning purely for learning’s sake, compared to most Type 8s. You’d prefer to focus on the essentials and the practical issues at hand, while your Type 8 counterpart typically wants to dig deeper and understand the bigger picture. In conversations, you may find that your Type 8 partner often gets caught up in theoretical or abstract details, and you need to bring them back down to earth.
Likewise, ISTPs and Type 8s share an appreciation for practical, tangible accomplishments over artistic expression. ISTPs and Type 8s are both likely to embrace conventional ways of thinking, and both types are more skeptical of eccentric or unusual approaches to solving problems.
Your organizational style describes your habits around organization and planning. Your organizational style influences how you structure your time and physical space. Differences in organizational style fall along two dimensions: industriousness and orderliness.
Industriousness describes your persistence, need for achievement, and intensity of focus. People higher on industriousness usually organize their behavior around a few important long-term goals. People lower on industriousness are usually more focused on the present and will more easily change their focus when new opportunities appear.
Orderliness describes your need for regularity, order, and structure in your environment. People higher on orderliness prefer tidy, organized physical spaces, detailed schedules, and reliable routines. People lower on orderliness can tolerate more disorganization and prefer a more spontaneous, unstructured approach.
The graph below shows the average position of ISTPs and Type 8s along these dimensions of organizational style.
Most ISTPs and Type 8s share a similar organizational style.
ISTPs and Type 8s often have big, ambitious goals, and they can be unusually resourceful. Once they’ve set their mind on a goal, they often pursue it with tremendous effort. However, ISTPs and Type 8s often resist highly structured, tedious approaches to achieving their goals. They’d rather avoid creating detailed plans and are more comfortable improvising and moving quickly with the resources they have on hand.
As a ISTP, you and most Type 8s share a natural drive to achieve and perform at a high level. Both of you enjoy setting goals and pushing yourselves to accomplish them, and you likely share an interest in self-improvement and productivity strategies. As a result, you and your Type 8 counterpart can fuel each other’s ambition and keep each other accountable as you work towards your long-term goals. However, between the two of you, nobody usually reminds you to slow down and enjoy the present.
Similarly, ISTPs and Type 8s share a more intuitive, unstructured approach to most areas of their lives. Both of you take life as it comes, and you avoid overly detailed plans and high levels of organization. Compared to most people, the two of you also have higher tolerances for messiness and disorganization.
Most people have complex personalities, and they don’t fit perfectly into a single personality type.
