Many people struggle with connection and conflict because the skills they need—validation skills—aren’t widely taught. But with her 2025 book Validation, clinical psychologist Caroline Fleck aims to fill this gap. Fleck breaks validation down into eight practicable skills you can use to change people’s behavior, make life feel more meaningful, and enhance any relationship, including your relationship with yourself.

Validation Summary Part 1: Why Validation Matters

You’ve probably heard of validation, but do you really know what it means? Fleck argues that we bandy the word about in popular culture but rarely define it precisely. As a result, most people don’t understand what validation is or how powerful it can be. Ahead, we’ll explore Fleck’s definition of validation and explain why it’s useful both in and outside of therapy.

(Shortform note: When a word with a specific meaning—like “validation”—becomes popular and gets used in ways that don’t reflect that meaning, linguists call it semantic drift. Semantic drift is also responsible for the way we often use “literally” to mean “figuratively” today. In the case of “validation,” some note that we often say things are “valid” to indicate that we see them as acceptable, when traditionally, to validate something meant seeing it as reasonable. But this isn’t the first time the meaning of validation has changed. When the word first came about in medieval times, we used it to mean to ratify or to make legally binding. Before that, [the root word...

Validation Summary Part 2: The Basics of Validation

Now that you understand what validation is and why it’s worth learning, let’s talk about how it works. Remember, there are three aspects to validation: being fully present, legitimizing, and supporting. In this section, we’ll break down some skills that can help you do each of these effectively.

How to Be Fully Present for Someone

Fleck says validation begins with being fully, nonjudgmentally present as you witness someone’s internal reality or the aspects of it they share with you. (Shortform note: Other experts suggest that while you want to give the other person your full attention, you don’t have to drop what you’re doing and stare into their eyes to hold space for them. In fact, engaging in activities together can make being fully present feel more relaxed and natural. Consider, for example, the “stitch ’n bitch”—a tradition where women work on fiber arts like knitting, crochet, or embroidery together while discussing their lives and the issues that matter to them.)

Fleck describes two...

Validation Summary Part 3: Validation in Everyday Life

In addition to the eight validation skills, Fleck offers tips for tailoring validation to fit different kinds of situations. Let’s explore her advice for self-validation, validation during conflict, and workplace validation.

Self-Validation

As we discussed in Part 1, many of us habitually invalidate ourselves, which needlessly amplifies our suffering and worsens mental health. But Fleck explains that you can start validating yourself by following a seven-step process:

1) Relax: When you feel overwhelmed, breathe slowly and try to relax your muscles. This calms your body, creating space for you to engage with your internal experience. (Shortform note: Asking a loved one for a hug may also help you relax. In The Body Keeps the Score, Bessel van der Kolk argues that physical touch such as hugging has a soothing effect, helping even victims of trauma feel protected and calm. If there’s no one around to ask for a hug, you can achieve a similar effect by hugging and rocking yourself.)

2) Engage: Put aside...

Shortform Exercise: Validate Yourself

Fleck explains that validating yourself can help you change your behavior, develop a deeper, more positive connection with yourself, and find a sense of meaning in your life. In this exercise, you’ll get some practice with self-validation.
