Preface Summary

Although not prized in modern culture and frequently teased or criticized as a defect, high sensitivity is “normal, a basically neutral trait” (xxxix). High sensitivity is usually inherited and is present in 15-20 percent of the population. It offers both challenges (like difficulty handling overstimulation) and marked advantages (including a subtle awareness of surroundings). Aron introduces the book as a guidebook for highly sensitive persons (HSP). It will provide information about the trait, advice about challenges HSPs face, and guidance for non-HSPs (as well as those who are moderately sensitive) on having close relationships with HSPs. Aron will also discuss different kinds of therapy for symptoms of high sensitivity.


More specifically, the book will follow a “fourfold approach” consisting of the following elements:


  1. Self-knowledge
  2. Reframing
  3. Healing
  4. Help with achieving the right level of involvement in the world


Aron lays out her own background and credentials as a psychologist, professor, psychotherapist, and novelist who is an HSP. She provides some details about her childhood, education, and personal life, and she describes the therapy session that opened the door to exploring her own high sensitivity. The book is the product of several years of research and teaching about high sensitivity, a trait about which almost nothing had been written before. Aron emphasizes that the book will foster solidarity among HSPs and will help them evaluate their lives in light of the trait.

Chapter 1 Summary: “The Facts About Being Sensitive: A (Wrong) Sense of Being Flawed”

This chapter introduces “basic facts” about high sensitivity, using two individuals as case studies. Kristen was highly sensitive to noise and stimulation as a child and later, as a young adult, became depressed before joining Aron’s experiment group. Aron uses Kristen’s case as a springboard to discuss two facts about high sensitivity:


  1. “Everyone, HSP or not, feels best when neither too bored nor too aroused” (6).
  2. “People differ considerably in how much their nervous system is aroused in the same situation, under the same stimulation” (6).


HSPs are able to notice different levels of stimulation, including subtle physical sensations—a trait that makes HSPs “more intuitive” and even “visionary” and that almost constitutes a “sixth sense.” The downside of this special gift is that HSPs tend to shut down amid “more intense levels of stimulation” (7). Stimulation (See: Index of Terms) can operate on HSPs on a subliminal level, wearing them down subconsciously until they crack.


Aron stakes a claim that societies traditionally have consisted of two groups, the “royal advisors” and the “warrior kings.” This dichotomy can be traced to the Indo-Europeans, the group that migrated to various areas in Europe, the Middle East, and South Asia in prehistoric times and brought slavery, domination, and war to those areas. The Indo-Europeans established the two governing classes that continue to exist in different forms today and that balance each other’s qualities. In a major claim, Aron identifies the royal advisor class with HSPs, consisting today of “writers, historians, philosophers, judges, artists, researchers, theologians, therapists, teachers, parents, and plain conscientious citizens” (18). The role of these professions is often to make the more aggressive majority stop, think, and consider their actions. Aron argues that this role as fulfilled by HSPs is vital to society.


Aron poses one more real-life example: that of Charles, another of her interviewees. In contrast to Kristen, Charles is secure and confident in his high sensitivity. He was brought up in a cultured family that fostered and respected his trait and, as a result, today he is highly successful and well adjusted. He has managed to organize his life around his trait and has thus achieved contentment.


To conclude the chapter, Aron sums up the main points and stresses the need to take pride in high sensitivity going forward in the book. She encourages readers to think carefully about major changes in their lives and analyze how they reacted or should react now to those changes in light of their high sensitivity.

Chapter 2 Summary: “Digging Deeper: Understanding Your Trait for All That It Is”

Aron proposes to convince readers that high sensitivity is real by means of a case history and scientific evidence. Rob and Rebecca were twins who had opposite temperaments: Rob sensitive, Rebecca nonsensitive. Rob was troubled with bad dreams and upset by loud noises and strange sights; he was also imaginative, funny, loved music, and was highly perceptive. Rebecca did not show the sensitive traits of her brother but acted as “the anchor in her brother’s life” (27).


Aron considers the reasons for the twins’ differing personalities. Some researchers believe that sensitivity results from the balance of two different systems in the brain: the “behavioral activation” system (which moves us toward desirable things) and “behavioral inhibition” system (which makes us attentive to dangers). Aron renames the latter “the automatic pause-to-check system” (30) and specifies that HSPs have a more active version of this system, caused by their “subtle processing of sensory information” (30). The two systems are often in conflict in HSPs, with one or the other predominating in a “power struggle” that mirrors the dichotomy between the warrior and advisor classes.


Sensitivity differs at each stage of a child’s development, a development that Aron charts in the section “You Are More Than Genes and Systems.” A baby starts out reacting to the world around it with irritability, but gradually it learns to filter things in the outside world according to whether they are helpful or harmful. In this way, the child learns to balance the behavioral-activation and behavioral-inhibition systems. Parenting is very important here, as sensitive children who are “securely attached” to their mother will not develop excessive levels of cortisol, a harmful product of stress. Having an attentive caretaker can mitigate the effects of high sensitivity, allowing the sensitive child to more securely try unfamiliar experiences.


The research of Carl Jung and depth psychologists has confirmed the importance of being connected to one’s unconscious as key to living a fulfilling life, and Aron argues that HSPs have this connection to a high degree. Although our culture at large sees only the darker aspects of high sensitivity and the psyche (including “fear, timidity, inhibitedness, and distressed overarousal” [37]), this is a bias that ignores the main, positive feature of HSPs: their “sensitive processing of subtle stimuli” (37).


At the end of the chapter, Aron invites readers to practice a deep-breathing exercise and observe and record their feelings.

Preface-Chapter 2 Analysis

In this initial section, Aron introduces the themes and purposes of the book. She identifies her credentials to speak on the topic of high sensitivity, stressing not only that she is a psychologist who has spent years researching the topic, but also that she herself identifies as an HSP. Aron’s use of case histories drawn from her own research solidifies her credibility and experience on the topic, as well as personalizing the topic for readers. These case histories are closely integrated into the text and serve to give an anecdotal context to the ideas Aron discusses. The book’s structure frames it as a manual for living with high sensitivity: After the preface, Aron offers a diagnostic self-test, and subsequent chapters focus on specific areas of life, addressing The Challenges and Benefits of High Sensitivity and offering advice for how HSPs can ensure that their needs are met and their unique contributions recognized. She proposes that HSPs practice a “total immersion,” in which they examine various aspects of their lives in terms of their trait. To this end, Aron includes a variety of self-tests and assessments (either in the middle or at the end of a chapter) for HSPs to do. 


In the Preface, Aron specifies the audience for the book: HSPs as well as those who have close relationships with HSPs and would like to understand their loved ones better. Further, the book aims to connect HSPs and foster understanding, solidarity, and pride in their trait. An important theme of the book (first articulated in Chapter 1) is Challenging Societal Misconceptions About High Sensitivity: The contemporary world is increasingly under nonsensitive influences, meaning that HSPs are misunderstood and marginalized; indeed, they are an “invisible” minority. Aron intends to equip HSPs to take charge and make their influence felt in all areas of human activity, because their influence is especially needed today. As she notes in Chapter 1, “HSPs do more of that which makes humans different from other animals: We imagine possibilities” (12). To build a better, more just world, one needs to be able to see what’s wrong with the world as it is and imagine how it could be otherwise. These are two areas, Aron argues, in which HSPs excel. 



This purpose of the book is closely related to Aron’s theory of the two classes of society. From ancient times, she claims, society has been balanced between “warrior kings” and “royal advisors.” She uses this broad framing of human history as a metaphor for the relationship between HSPs and non-HSPs. In recent times, she argues, the more aggressive character and values of the first group have become dominant. But for the warrior kings, and the societies they lead, to survive, they need the wisdom and guidance of the royal advisors. The book thus aims at increasing HSPs’ self-confidence so they can take their place as leaders in society. Aron hopes to clarify and defend high sensitivity as a personality trait of great benefit to humanity.


Especially in the earlier part of the book, Aron errs on the side of portraying HSPs in as positive a light as possible. This, as she explains, is to act as a counterbalance to the general neglect and negativity associated with high sensitivity. However, in the latter part of the book she brings more complexity to the portrayal, emphasizing the specific liabilities that come with the trait—especially a tendency to become overstimulated or “overaroused” and a corresponding need for quiet and rest—and how HSPs can counterbalance those qualities to optimize their lives. This advice—a thread running throughout the book—advances the theme of Personal Growth and Self-Care for HSPs. In the end, the book drives home the point that sensitivity is a personality type that confers both advantages and challenges. Aron’s comparative method aims to help readers see high sensitivity in relation to other personality types and in a variety of real-life contexts. She defines sensitivity as consisting of various components (depth of processing, overstimulation, etc.) and stresses that degrees of sensitivity exist throughout the population (including among HSPs themselves), thus avoiding the impression that sensitivity is an all-or-nothing matter.


Throughout the book, Aron makes a point to include herself in the group she labels HSPs. She uses “we” and “our” frequently and thus establishes her solidarity with HSPs. The tone of sympathy helps draw readers in and establish a positive aura around high sensitivity, as well as a sense that HSPs are all in it together. Occasionally Aron steps in with a comment directed at HSPs about what they might be feeling at that point in the narrative: “This first chapter may have been very stimulating! All sorts of strong, confusing feelings could be arising in you by now” (20). These interventions serve to convey the sympathy and compassion that are central to Aron’s style.


Aron’s specific goal in the first two chapters is to orient readers to see and identify high sensitivity. To this end, Aron debunks various misconceptions and biases about the trait, and identifies its key components in a more objective light than society typically allows. For example, Aron argues that the traits that modern Western societies typically value less (like restraint and reticence) are the very ones that are typical of HSPs; but these traits are in fact very common in the population and not at all abnormal. Also, sensitivity in boys is discouraged, yet just as many male babies as female babies exhibit sensitivity. Essentially, Aron argues that society and culture mold human beings in a way that contradicts the facts of nature.
