• Admitting you don’t know is powerful
  Many people pretend to know things to protect their image, but this prevents learning. By saying “I don’t know” and committing to find out, you build trust and open the door to real discovery. Honesty about limits makes you smarter and more respected over time.

• We confuse beliefs with facts
  People often treat beliefs, things they feel are true, as if they were proven facts. This mistake leads to poor decisions and blind spots. To think clearly, separate what can be tested from what is just opinion, and be willing to challenge assumptions that may not reflect reality.

• Confirmation bias blocks learning
  Humans naturally seek information that supports their views while ignoring evidence that contradicts them. This makes us blind to reality and resistant to change. Recognizing this bias allows us to actively look for opposing proof, leading to deeper understanding and better solutions.

• Overconfidence creates errors
  Most people believe they are better than average at skills such as driving or decision-making. This overconfidence leads to poor judgment and risk-taking. By being humble about your abilities and open to feedback, you can avoid mistakes and grow faster than those who assume they already know enough.

• Consequences of guessing are small
  People often give confident answers even when unsure, because being wrong has fewer social costs than admitting ignorance. The problem is that this spreads misinformation. By choosing honesty, you may look unsure at first, but over time, people respect your integrity and reliability more than false confidence.

• Experiments reveal truth
  The best way to find out what works is to test it. Lab, field, or natural experiments give evidence that theory alone cannot. Running experiments helps you see if your ideas hold up in reality, reduces risk, and uncovers insights you would otherwise miss.

• Identify the real problem
  People often solve the wrong issue because they focus only on what looks obvious. To think like a freak, dig deeper to find the root cause instead of treating symptoms. Redefining problems leads to creative solutions that others overlook, making progress more likely.

• Think like a child
  Children ask simple questions, challenge assumptions, and see things with fresh eyes. By adopting this mindset, adults can uncover overlooked insights. Curiosity, playfulness, and openness help generate more creative ideas than relying only on experience and traditional thinking.

• Question the obvious
  We often accept familiar routines or “the way things are” without questioning them. Asking why things are done a certain way can uncover outdated practices and inspire innovation. What feels obvious may hide opportunities for smarter, faster, or simpler solutions.

• Generate many ideas without judging
  When brainstorming, separating idea creation from evaluation leads to more originality. Write down everything first, then filter later. This prevents self-censorship and allows surprising, unconventional ideas to emerge, which might hold the key to solving tough problems.

• Having fun sparks creativity
  When you enjoy what you’re doing, you ask better questions, spend more time practicing, and notice details others miss. Fun creates intrinsic motivation, which fuels innovation and persistence far more effectively than pressure or external rewards alone.

• Incentives drive behavior
  People respond to what benefits them, even if their stated reasons differ. By understanding proper incentives, what people actually do, not what they say, you can design systems that guide behavior effectively. Solutions that align with human incentives are more likely to succeed.

• Declared vs. revealed preferences
  People say one thing but often do another. Real behavior shows their true motivations. For example, many claim to save energy for the environment, but what actually changes behavior is knowing neighbors are doing it too. Observing revealed preferences uncovers real drivers of action.

• The herd mentality shapes choices
  Humans copy others to fit in. Social proof is a powerful incentive that can be stronger than money or morality. This can be used positively (encouraging good habits by showing that others do them) or negatively (falling for harmful trends).

• People act selfishly by default
  Most choices are guided by self-interest, not group benefit. This is natural, not evil. To design effective solutions, assume people will act for themselves first and build systems that align selfish motivations with collective good.

How 433 Investors Unlocked 400X Return Potential

Institutional investors back startups to unlock outsized returns. Regular investors have to wait. But not anymore. Thanks to regulatory updates, some companies are doing things differently.

Take Revolut. In 2016, 433 regular people invested an average of $2,730. Today? They got a 400X buyout offer from the company, as Revolut’s valuation increased 89,900% in the same timeframe.

No wonder 10K+ everyday people are taking the chance on Pacaso.

Founded by a former Zillow exec, Pacaso’s co-ownership tech reshapes the $1.3T vacation home market. They’ve earned $110M+ in gross profit to date, including 41% YoY growth in 2024 alone. They even reserved the Nasdaq ticker PCSO.

The same institutional investors behind Uber, Venmo, and eBay backed Pacaso. And you can join them. But not for long. Pacaso’s investment opportunity ends September 18.

Invest While You Still Can

• Fear of embarrassment guides actions
  In situations like sports, people sometimes make suboptimal choices just to avoid looking foolish. This shows how much social pressure shapes behavior. Recognizing this helps explain irrational actions and allows leaders to design environments that reduce unhelpful social fears.

• Design self-selecting incentives
  Smart systems encourage people to reveal who they are. For example, tough job applications filter out uncommitted candidates. Designing incentives that attract the right people and discourage the wrong ones helps organizations align actions with goals without direct enforcement.

• Beware of backfiring incentives
  Poorly designed incentives can create the opposite of what you want. Offering money to reduce bad behavior may encourage people to produce more of it for profit. Always consider unintended consequences when building incentive systems.

• The cobra effect is real
  History shows that incentives can be abused. Paying for cobra skins in India led to the development of cobra farming. Similar schemes today show that people will exploit systems for gain. Smart problem solvers anticipate these loopholes before incentives are launched.

• Opportunity costs matter
  Every choice means giving up other opportunities. Many people overlook this, wasting time on less valuable goals. Evaluating what else you could be doing helps you choose better paths and avoid regret. Wise thinkers compare trade-offs, not just direct benefits.

• Quitting is not failure
  Sometimes quitting is the smartest choice. Sticking with a dead-end project wastes time, money, and energy. Quitting frees resources for more promising opportunities. Knowing when to stop is as important as knowing when to persist.

• The sunk cost trap holds people back
  People continue to invest in failing projects because they don’t want to “waste” what they have already spent. But those resources are gone. Smart thinkers cut losses quickly instead of letting sunk costs drag them further down.

• Premortems prevent disaster
  Instead of waiting for failure to analyze mistakes, plan ahead by asking, “If this failed, why would it have failed?” This exercise surfaces hidden risks and allows you to prepare in advance, reducing the chances of failure later.

• Luck is often mistaken for skill
  People admire bold predictions when they turn out right, but often it is just luck. With many people making guesses, someone will always be right by chance. Don’t confuse luck with skill; instead, focus on consistent methods that improve outcomes.

• Social perception shapes truth
  People are more influenced by how actions look than by actual results. For example, players or leaders often act to avoid looking foolish rather than to optimize outcomes. Being aware of perception bias helps you make smarter, less pressured decisions.

• Fun can motivate others too
  When you make tasks enjoyable, you encourage participation. Gamification, rewards, or playful competition can encourage people to act in ways that benefit themselves and the group. Fun is a powerful tool for driving positive behavior change.

• Think in experiments, not guesses
  Approach decisions like a scientist: form a hypothesis, test it, and learn from results. This prevents you from relying only on instinct or tradition. Even small tests can reveal useful insights and prevent large, costly mistakes.

• Children’s mindset uncovers hidden insights
  Kids ask endless “why” questions and notice details adults miss. By adopting this habit, adults can reframe problems and find creative solutions. Curiosity and fresh perspectives break patterns that block innovation.

• Persistence has limits
  Hard work and grit are important, but blind persistence can trap you in failure. Smart persistence means balancing effort with reflection, knowing when to push harder and when to pivot or quit entirely.

• Thinking differently leads to breakthroughs
  The core lesson is to think differently from the crowd: admit ignorance, test assumptions, focus on incentives, and don’t fear quitting. This unconventional approach creates surprising but effective solutions that traditional thinking often overlooks.

What’s Next?

Next time you face a problem, pause before following the usual path. Ask a childlike “why” question, test your assumptions, and explore incentives. If the path feels wrong, don’t be afraid to quit and redirect. Thinking like a freak means daring to see what others ignore.
