You might read every message twice, looking for what it really means. You might keep people at arm's length, or wait for the moment a kind person shows another side. Part of you would like to relax. Another part is sure that relaxing is how you get hurt.
This article looks at what trust is, why it can be hard to give, how hypervigilance differs from reasonable caution, and when distrust is a signal about safety rather than a pattern from the past. It does not diagnose you or anyone in your life.
What makes trust possible?
The American Psychological Association's (APA) dictionary describes interpersonal trust as "the degree to which each party feels that they can depend on the other party to do what they say they will do." It adds: "The key factor is not the intrinsic honesty of the other people but their predictability."
That may help explain why trust can be hard for people who grew up with care that came and went, or who have been with someone whose moods set the weather. Trust is not only a belief about whether someone is good. It is a sense of being able to predict them.
Why does trust become hard?
Often because of something that happened. A Cleveland Clinic article quoting psychologist Ramone Ford, PhD, says that, unlike paranoia, "trust issues are rooted in the reality of our experiences." It names behaviors that can damage trust, including lying, manipulation, breaking promises, withholding important information and doing something intentionally hurtful. Signs of trouble trusting include "Second-guessing yourself or others" and "Being guarded, closed-minded or withdrawn."
The APA dictionary defines betrayal broadly, as any act by one partner "that violates the other's expectations of that partner," including lying, disloyalty, revealing secrets, lack of support or broken promises. Psychologist Jennifer Freyd introduced the research term betrayal trauma for when "the people or institutions on which a person depends for survival significantly violate" that person's trust or well-being, as in abuse by a caregiver. It is a research term, not a diagnosis.
Can early experiences make trust harder?
They can. Dr. Ford puts it this way: "Early in life, you form expectations and beliefs that the world and certain people will act a certain way," and "If your needs aren't met earlier in life, it becomes harder to build those connections and to open up and be vulnerable in relationships."
In Erik Erikson's theory of development, an infant's first task is basic trust versus mistrust. The APA dictionary says that, in this theory, trust grows with a caregiver who is "responsively attuned to the infant's individual needs," and mistrust with "neglect, lack of love, or inconsistent treatment." It also notes that "The child must experience both trust and mistrust to know how to truly trust." This is a theory, not proof that adult distrust comes from infancy. Later betrayals matter too. How early adversity can carry into adult life is covered in childhood trauma in adults.
Hypervigilance or reasonable caution?
The APA dictionary defines hypervigilance as "a state of abnormally heightened alertness, particularly to threatening or potentially dangerous stimuli." A Cleveland Clinic article quoting psychologist Susan Albers, PsyD, is clear that "hypervigilance isn't a diagnosis. It's a symptom" that can occur with many conditions. In relationships, it says, a hypervigilant person may watch others closely "for slight changes in behavior, tone, cadence, body language, written communication or even sentence structure." These traits are "especially common in people who've endured abuse or been exposed to violence."
The same article makes a fair point: hypervigilance is "a legitimately helpful instinct." A child who learns to read a parent's mood may be keeping themselves safe. Caution is reasonable when you are getting to know someone, or when someone has given you real reason for concern. It can become costly when it never switches off, even with people who have been reliable for a long time.
Dr. Albers adds that if hypervigilance is chronic or severe, "it's usually a symptom of a mental health disorder." The UK's National Health Service, for example, lists "looking for danger all the time (hypervigilance)" among the symptoms of post-traumatic stress disorder (PTSD). Feeling watchful does not by itself mean you have PTSD or any other condition. Only a clinician can assess that.
When is distrust a sign to look at your safety?
Sometimes distrust is accurate. The National Domestic Violence Hotline describes abuse as "a pattern of behaviors used to gain or maintain power and control." Warning signs it lists include "Preventing or discouraging you from spending time with others," "Controlling finances in the household without discussion" and "Intimidating you through threatening looks or actions." It notes that "even one or two of these behaviors in a relationship is a red flag that abuse may be present."
If a partner is controlling, threatening or hurting you, the problem is not your capacity to trust. The Hotline does not encourage couples counseling with an abusive partner: "Abuse is not a relationship problem." You can talk with an advocate at the National Domestic Violence Hotline, free, confidential and open 24/7, at 1-800-799-7233 or by texting START to 88788. In Massachusetts, SafeLink is at (877) 785-2020. If you are in immediate danger, call 911.
Can trust be rebuilt, and how can therapy help?
It can take time. The Cleveland Clinic article on trust issues says "it may take months or even years to feel like you're able to fully trust someone" and that "Healing isn't linear." It adds that "Therapists can validate your fears and feelings and help you identify the problem areas where trust becomes difficult for you."
Trust is also part of therapy itself. The APA dictionary notes that trust is considered by most psychologists to be "a primary component in mature relationships with others, whether intimate, social, or therapeutic." Dr. Rabin's individual therapy for relationship patterns works with trouble trusting, fear of abandonment and recurring conflict. Her approach is psychodynamic and attachment-based. It traces how early relationships shape present ones and uses the therapy relationship itself as a place to notice patterns as they happen and to practice relating differently.
