How ISTP and ISFP Get Along

ISTPs and ISFPs have some common themes that often arise when they get to know each other. As an ISTP, you'll want to keep these issues in mind when you get to know an ISFP.

As a Sensing Perceiver type, your approach to relationships is perhaps the most straightforward of all the types—you look for connections with people who are up for joining you on all of life's adventures. You may tend to gravitate towards people with a similar background to yours, but you just as easily accept people from all walks of life, so long as you can enjoy your time together. You especially value relationships with people who share your hobbies and interests and a can-do approach to life.

Your counterpart is a Sensing Perceiver type, which means their core focus is enjoying the moment. In relationships, this means that they look for people that they have an easy synergy with, and often prioritize one thing: FUN. As an SP type, your counterpart doesn't think too hard about whether they connect with other people on a deep level. They're simply looking for companions to keep them company on this crazy ride called life.

The two of you share a casual, spontaneous approach to life and and interest in enjoying the moment. You both like to experience the world rather than analyze it, and you’ll probably bond when you discover the things you like to do together. 

Although there are some common problems that can arise in ISTP/ISFP relationships, it's important to remember that there's no such thing as a perfectly compatible pair in personality typing. Whether you get along with someone has more to do with your own self-knowledge and your sensitivity to your friend's needs and preferences—not some magic formula. Learning more about your own type with an in-depth assessment is a great place to start to build the self-awareness that is key to successful relationships.

Communication Between ISTP and ISFP

Communication can be a challenge between any two people, and communication between ISTP and ISFP personality types is not the exception. By being aware of the issues that often arise when ISTPs and ISFPs communicate, you can learn how to reach an understanding more quickly.

Be aware that when communicating with this person, your usual style may come off as overly blunt or even confrontational. Your counterpart pays a lot of attention to the quality of relationships and is constantly monitoring the emotional overtones of any conversation. This means that they are reluctant to say anything controversial or possibly upsetting.

You, on the other hand, have a tendency to call it like it is, without too much concern for how people will react. This can create an imbalance in your dynamic, where your Feeling counterpart is desperately trying to maintain emotional harmony while you relentlessly rock the boat.

You'll be more successful in your communications if you take time to consider the emotional impact of your words. Sure, everyone wants honesty, but most people also like tact. If you're delivering news that may be hard to hear, think about how you can soften the message. And be aware that your ever-so-charming habit of offering unsolicited "constructive criticism" may not always be taken in the spirit it was intended.

ISTP vs. ISFP Values

Values are intensely personal, and while an ISTP and an ISFP can find common ground, there will always be some differences in what you hold dear. However, understand how your ISTP approach to values compares with your ISFP counterpart's will help you to appreciate and overcome your differences.

Both of you are traditionalists and there are many similarities in what you value. You each put faith in the past and trust what has worked for many generations before you. The two of you share an appreciation for the rules and feel comforted, rather than restricted, by institutions and traditions. You are likely to feel a strong connection with this person based on your fundamental similarities in values and approaches.

At heart, you are both deeply practical and logical people. You have a strong sense of duty, and will both play your parts as morally upstanding and socially responsible members of your communities. You both embrace responsibility, and seeing your commitments through to completion is an ethical obligation for both of you. It is unlikely that you would carelessly let the other person down.

You have somewhat different values when it comes to relationships. You tend to be more emotionally distant, and may hurt your counterpart with your blunt and sometimes tactless words. Your counterpart tends to take criticism personally and may get overly emotional and defensive in the face of negative feedback. In your defense, you may not understand the depth of your counterpart’s people-orientation and desire for emotional connection, and may not realize that you are being insensitive. To smooth the waters, you may have to dig deep into your feelings and find an emotional connection, which is your counterpart’s preferred way of navigating the world.

Your counterpart, on the other hand, tends to be intensely interested in people and are eager to serve them in practical ways. They are compassionate and emotionally engaged, and they seek harmony in their relationships. Unlike you, they prioritize closeness and connection and tend to over-worry if they are not getting the intimacy they desire.

Fundamentally, you counterpart tends to show affection much more naturally than you do. While you may initially be attracted to your counterpart’s kind and tender heart, there’s a chance that you will feel frustrated by their complicated emotions. On the flip side, your partner may feel unfulfilled by your objective and tough-minded approach.

There’s an opportunity here to introduce one another to new ways of thinking. You both excel in sticking to values that are important to you, but your counterpart can help you understand the emotional consequences of your behavior, while you can help your counterpart lead with the head instead of the heart. The challenge for you is to not get too annoyed if your partner is a little too needy or becomes defensive to the point of passive-aggression if you criticize their habits or beliefs.

ISTP and ISFP in Daily Life

Lifestyle is an under-appreciated—but extremely important—element of compatibility. Your values and ideals may coincide perfectly, but if you can't agree on how to conduct day-to-day matters, your relationship will always have friction. As an ISTP in a relationship with an ISFP, you can expect certain issues to arise in your daily life. Discussing these in advance, and figuring out how to deal with them, will make things go much more smoothly as you develop your relationship.

You take a similarly unstructured approach to life and are fairly relaxed about schedules, plans and household systems. If you share space, it’s likely that neither of you will be motivated to take on household responsibilities. You both prefer to play first and work later, and there may need to be some discussion about getting the chores done.

Since neither of you want things to be fully planned and predictable, you’re rarely overwhelmed by disorganization. You both enjoy leaving room for creativity, and enjoy setting a pace together that will allow you to do things on the fly.

The two of you want to know who and where you are in the world, and you likely will share a fondness for upholding traditions you can respect and value. While you may not share specific hobbies, you both will be concerned with history and tradition and celebrating important rituals like birthdays and anniversaries.

For both of you, actions speak louder than words. You enjoy experiences and probably share a mutual interest in activities that will stimulate your senses or your body in some way, whether that’s cooking, bungee jumping or arts and crafts. In fact, you may find that doing things together is a great way to bring you closer.

You recall events as snapshots of what actually happened, and have a low tolerance for metaphorical language and esoteric thinking. You both live life in the moment, and are good at thinking on your feet. This mutual taste for ‘doing’ things in the here and now is stimulating for both of you, and helps keep things running smoothly between you. However, during periods of unplanned changes in your life, it's likely that you'll both be a bit hesitant and cranky. Bear in mind that future planning, with all its associated flexibility, is key to both of your long-term happiness.

You both get overstimulated by too much activity and both enjoy spending quiet time alone. You and your partner might often find yourself at home with takeout and Netflix, or even in the same room without actually talking to each other, and you’re both okay with that. You likely both have small but intimate circles of friends and there may be no great urgency to work your way into each other’s friendship circles as a way of deepening your own bond. Personal boundaries are important to you, and you respect each other’s personal space by default.

You likely share a slower pace of life and appreciate the need for down time to balance out the busyness. Neither of you feels a burning desire to attend party after relentless party, and it’s likely that you’re on the same page regarding the booking of your social calendar. The problem is that when you do make plans, it can be dangerously easy for you to talk each other out of them. Hiding away is not healthy or practical. If your relationship is a priority, one of you must bite the bullet and motivate the other to follow through.

Despite both being introverts, one partner may need more down time than the other, or you may have different social needs. It’s a balancing act to sync your calendars and maintain a balance between your respective needs. Communication is key, although that too can be challenging as you both tend to shy away from confrontation because it’s overstimulating. Acknowledge when you’re bottling up feelings. Making a conscious effort to focus on conversations that take your both out of your comfort zones is the key to discovering new aspects of your relationship.
