Understanding people is both an art and a science. They’re complicated creatures—walking mysteries with motivations, emotions, and thoughts that often change in an instant. Yet, understanding people can profoundly transform how we interact with others, improve our relationships, and influence outcomes in both personal and professional settings.

In this blog, I’m walking you through key takeaways from Patrick King's bestselling book, Read People Like a Book. King has spent years studying social behaviors and explains how anyone can develop the skills needed to "read people" like an open book. Whether you want to decode body language, detect lies, or enhance communication, these insights will help you sharpen your natural intuition while applying practical frameworks. Let’s dive in! 🎯

Why Understanding People is a Mystery

Every individual’s internal world is a "black box." What's going on inside their mind—their thoughts, feelings, motivations—isn't always visible on the surface. In fact, as Patrick King explains, it’s common for the words people speak to misalign with what they truly think or feel.

So, how can you decode someone when they don’t outwardly express their inner emotions?

The good news: reading people is a skill anyone can learn. King’s book suggests starting with external signs, like expressions and body language, to form educated guesses about a person’s intentions or feelings. Mastering this skill can lead to better communication, stronger relationships, and even the ability to spot deception.

The Role of Context and Baselines in Reading People

Start With Context  

Let’s say someone stumbles over their words. Are they lying—or just tired? Context matters. A student nervously giving a presentation behaves differently from someone hiding a secret. Similarly, cultural influences shape how behaviors are expressed. Be mindful of the situation and background before jumping to conclusions.

Establish a Behavioral Baseline  

One of King’s standout tips is to always establish a baseline for a person’s normal behavior. For example, how do they act when relaxed, as opposed to stressed? Observing regular patterns will sharpen your ability to detect anomalies. When someone strays from their baseline—speaking too quickly, avoiding eye contact, or using different tone variations—it’s often an indicator something is off.

> Pro Tip: Be patient. Observing a baseline, even in short interactions, can provide critical clues about a person’s state of mind.

Behavior and Motivation: What Fuels Us?  

Understanding Jung’s Shadow Theory  

Carl Jung’s concept of the "Shadow Self" offers an intriguing perspective. The "Shadow" refers to the parts of ourselves we ignore or suppress, but it still influences our behavior. For instance, someone insecure about their intelligence may overcompensate by belittling others. Recognizing this projection of insecurities allows for increased compassion—or strategic influence.

Imagine complimenting such a person on their intellect. This might disarm their defensiveness and create an opportunity for connection or persuasion.

Freud’s Pleasure Principle  

Sigmund Freud’s Pleasure Principle explains that much of human behavior revolves around avoiding pain and seeking pleasure—even when it’s irrational. Procrastination, for example, often stems from prioritizing immediate comfort over long-term goals.

Take this idea into social contexts. If someone clings to a toxic habit like gambling, understanding that they’re seeking short-term pleasure over long-term well-being can guide your approach in connecting with them or helping them see the bigger picture.

> Quick Tip: When influencing someone’s decisions, ask yourself, what pain are they avoiding or what pleasure are they chasing?

Becoming a Human Lie Detector

The Challenges of Detecting Lies

Contrary to popular belief, there are no universally foolproof signs of lying. Some liars grow talkative and animated, while others retreat into awkward silence. Nervousness isn’t automatically deception—it could just be discomfort.

Here’s the catch: while lying may not come with a flashing neon sign, it does take considerable mental effort. Lies need to be fabricated, rehearsed, or adjusted in real time, which often results in inconsistencies or a subtle “coolness” to emotions.

How to Spot a Lie  

King outlines practical strategies:

1. Ask Open-Ended Questions: Encourage a liar to expand on their story. Lies often require rehearsing details, so deviations or inconsistencies are easier to spot this way.
2. Introduce the Element of Surprise: Start asking unrelated or unexpected questions. This disrupts their train of thought and adds mental strain.
3. Observe Emotional Disconnects: Someone lying about a happy event (e.g., claiming they spent a fun evening with friends) may lack the matching emotional enthusiasm in their tone or expression.

> Fact: Genuine behavior feels effortless, while lying introduces cognitive overload. Push a liar to keep track of "their story," and they’re more likely to slip up!

Reading Body Language Like a Pro  

Macro and Micro Expressions  

Psychologist Paul Ekman famously categorized facial expressions into two types:

1. Macro Expressions: Big, obvious responses like broad smiles or scowls, lasting up to four seconds.
2. Micro Expressions: Quick, involuntary flash reactions, lasting just a fraction of a second.

Observing fleeting micro-expressions can reveal someone’s true feelings before their conscious mind corrects it. For instance, a brief look of annoyance may escape during a polite smile.

Body Language Signals  

Key observations include:

• Self-Soothing Gestures: Rubbing the neck, fiddling with a tie, or touching the face can indicate stress.
• Leg or Lip Movements: Rubbing thighs or biting lips may show anxious energy.
• Overcompensating Confidence: Exaggerated gestures could denote discomfort or insecurity.

By tuning into these nonverbal cues, you can pick up on hidden emotional states—even when someone insists “everything’s fine.”

Trusting Your Gut Instinct  

While tools like observational analysis are tremendously helpful, don’t underestimate your own instincts. Ample research, as discussed in Malcolm Gladwell’s Blink, shows that gut feelings can be surprisingly accurate when paired with conscious deliberation.

King stresses a balanced approach:

1. Allow your initial snap judgment to surface naturally.
2. Back up or challenge your gut instincts with an analysis of body language, context, and verbal cues.

A Real-Life Example  

Imagine you’re at a job interview. Within moments, something feels off about the interviewer. During the conversation, you notice inconsistencies in their story and fidgety movements. Later research reveals the company has high turnover due to toxic management. Your initial gut feeling, supported by observed data, kept you from stepping into a potentially damaging situation.

Conclusion: Reading People is a Skill You Can Master
