1. Your brain has three parts: old, mid, and new, all working together

What really makes us human is that we have all three.

The triune brain. Our brain consists of three interconnected parts: the old brain, mid brain, and new brain. The old brain, our most primitive part, is responsible for survival instincts, automatic functions, and constantly scanning for danger. The mid brain processes emotions and drives impulsive behavior. The new brain, or cortex, handles language, reasoning, and conscious thought.

Interplay of brain parts. These three brain systems work in concert, influencing our perceptions, decisions, and actions. For example, while driving (old brain), we might think about an argument (new brain) and feel upset (mid brain). This interplay explains why our physical state affects our emotions and thoughts, and vice versa.

Evolutionary perspective. This three-part structure reflects our evolutionary history, with each part developing at different stages. Understanding this helps explain why we sometimes act irrationally or against our conscious intentions – our older brain systems can override our newer, more rational ones.

2. The unconscious mind drives most of our decisions and actions

Our unconscious minds are very smart. But we don't control them.

Unconscious power. The unconscious mind processes an estimated 11 million bits of information per second, compared to only 40 bits processed consciously. This vast computational power allows us to navigate complex environments and make rapid decisions without conscious effort.

Hidden influences. Research shows that our behavior is often influenced by factors we're unaware of:

• In word-scrambling experiments, participants' subsequent behavior was influenced by the types of words they unscrambled, without their knowledge.
• In gambling experiments, participants' physiological responses indicated awareness of optimal strategies long before they consciously realized it.

Implications. Recognizing the power of the unconscious mind has profound implications for marketing, design, and personal decision-making. It suggests that appealing to unconscious processes may be more effective than purely logical arguments.

3. We are powerfully influenced by social validation and the need to belong

People look to others to decide what they should do. This is especially true when they are uncertain about whether or what action to take.

Social creatures. Humans have a deep-seated need to fit in and belong, which is wired into our brains and biology. This drive often leads us to look to others for cues on how to behave, especially in uncertain situations.

Power of social proof. Social validation significantly influences our behavior:

• In emergency situations, the presence of others can actually reduce the likelihood of an individual helping (bystander effect).
• Online, the number of positive reviews or ratings can greatly influence our perception of a product or service.
• Even in trivial matters, like choosing cookies, we tend to prefer options that others have chosen.

Leveraging social validation. Websites and marketers can harness this tendency by:

• Displaying customer reviews and ratings prominently
• Showing how many people have purchased or used a product
• Highlighting popular choices or "trending" items

4. Reciprocity and concession are potent tools of persuasion

If I give you a gift or do you a favor, you will feel indebted to me.

The reciprocity principle. When someone does something for us, we feel a strong urge to reciprocate. This principle is deeply ingrained in human societies and has been crucial for cooperation and survival.

Reciprocity in action:

• In experiments, people were more likely to buy raffle tickets from someone who had given them a soda earlier.
• Providing free samples or information can create a sense of obligation in potential customers.
• Even small gestures, like personalized address labels in donation requests, can significantly increase response rates.

The power of concession. A related principle is concession, where rejecting a larger request makes people more likely to agree to a smaller one. This "rejection-then-retreat" technique can be highly effective in negotiations and sales.

5. Scarcity makes us want things more, but too many choices paralyze us

If it's scarce, we think it is more valuable and more desirable. We'll want it more.

Scarcity's allure. When something seems rare or limited, we tend to value it more highly. This principle applies not just to physical goods, but also to information and opportunities.

Examples of scarcity in marketing:

• Limited-time offers
• "Only X left in stock" notifications
• Exclusive access or memberships

The paradox of choice. While we think we want many options, having too many choices can actually hinder decision-making:

• In the "jam study," more flavors attracted more people, but fewer actually purchased.
• Too many options can lead to decision paralysis and less satisfaction with our choices.

Implications for design. When presenting options, it's often better to offer a carefully curated selection rather than an overwhelming array of choices.

6. We are self-centered beings, attracted to danger, food, and sex

To the old brain, everything is all about you. You are all that matters.

The self-centered brain. Our old brain is primarily concerned with our own survival and well-being. This self-focus is not a moral failing, but a fundamental aspect of our neural wiring.

Attention-grabbing stimuli. The old brain is particularly attuned to:

• Danger: Anything threatening captures our attention quickly
• Food: Images of food are inherently engaging
• Sex: Even subtle sexual cues can be powerful attention-grabbers

Implications for communication. To engage the old brain effectively:

• Use the word "you" frequently
• Incorporate images or themes related to danger, food, or sex when appropriate
• Ensure content changes or moves to maintain attention

7. Fear of loss is a stronger motivator than the prospect of gain

We are programmed to pay attention to, and to avoid, loss.

Loss aversion. Humans are generally more motivated to avoid losses than to acquire equivalent gains. This tendency is deeply rooted in our psychology and influences many of our decisions.

Examples of loss aversion:

• People are more likely to take risks to avoid a loss than to secure a gain
• Framing a medical treatment as having a "90% survival rate" is more effective than saying it has a "10% mortality rate"
• In marketing, emphasizing what customers might lose by not acting can be more persuasive than highlighting potential gains

Unconscious awareness. Our bodies and unconscious minds often detect potential losses before we're consciously aware of them, as shown in experiments where physiological responses precede conscious realization.

8. Stories and pictures are the most effective ways to communicate

If you want to get and hold someone's attention, tell a story.

The power of narrative. Our brains are wired to process and remember information in story form. Stories engage multiple brain areas, making the information more memorable and impactful.

Visual processing. A significant portion of our brain is dedicated to visual processing, making images particularly effective for communication:

• We can remember more than 2,500 pictures with 90% accuracy
• We remember only 10% of what we hear or read without pictures

Combining stories and visuals. The most powerful communication:

• Uses both narrative and visual elements
• Breaks information into digestible "chunks"
• Engages emotions as well as intellect

9. We are inherently social animals, always seeking connection

We are social animals. Being human means being social.

The social imperative. Throughout history, humans have consistently adapted new technologies to serve social purposes. This tendency is deeply rooted in our evolution as a species.

Examples of technology becoming social:

• The printing press enabled mass communication
• Telephones, initially intended for business, became household items
• The internet, originally a military project, became a global social network

The rise of social media. Platforms like Facebook, Twitter, and LinkedIn are natural extensions of our social nature, enabling unprecedented levels of connection and information sharing.

10. Effective Web design leverages our psychological tendencies

Web sites that "speak" to all three brains (old brain, mid brain, new brain) are the most effective.

Holistic design approach. To create compelling websites, designers should consider how to engage all aspects of the brain:

• Old brain: Use danger, food, or sex-related imagery; incorporate movement or change
• Mid brain: Evoke emotions through stories and visuals
• New brain: Provide logical arguments and data

Key design principles:

• Use social proof (reviews, ratings, user numbers)
• Create a sense of scarcity or urgency
• Offer a carefully curated set of choices
• Incorporate storytelling and strong visuals
• Leverage reciprocity (e.g., free information or tools)

Ethical considerations. While these principles can be powerful persuasion tools, it's crucial to use them ethically and in ways that genuinely benefit users.
