Habit Formation: The Science of the 21-Day Myth

    “It takes 21 days to form a habit.” I’ve heard this approximately one million times. Self-help books. Productivity blogs. Motivational Instagram posts. Life coaches. So I tried it. Day 1-7: Woke up at 6 AM to code before work. Felt great! I’m building a habit! Day 8-14: Woke up at 6 AM most days. Missed a few. Still committed! Day 15-21: Made it to Day 21! The habit is formed, right? ...

    Variable Rewards: The Psychology Behind Addictive Apps

    I checked Twitter 47 times yesterday. Not because I needed information. Not because I was expecting something important. Just… checking. Pull down to refresh. Scan. Nothing interesting. Close app. Five minutes later: Open app. Pull down to refresh. Scan. Find one mildly interesting tweet. Read. Close app. Repeat. All day. I wasn’t looking for something specific. I was looking for the possibility of something interesting. And that’s exactly how Twitter (and every other addictive app) is designed to work. ...

    The Psychology of Conspiracy Theories: Why Smart People Believe Irrational Things

    My uncle is intelligent, educated, and successful. He runs a business, reads extensively, and can hold sophisticated conversations about history, economics, and technology. He also believes: COVID-19 was created in a lab as a bioweapon The 2020 election was stolen A global elite controls world events through secret organizations Vaccines contain tracking microchips Climate change is a hoax to implement global government When I try to discuss evidence, he responds with: ...

    Free Will: A Psychological Illusion? (What Neuroscience and Psychology Really Tell Us)

    At 3:47 PM on a Tuesday, I decided to quit my job and start a company. Or did I? Maybe the decision was already made by unconscious neural processes seconds before I became aware of it. Maybe my genes, my upbringing, my brain chemistry, and the exact configuration of neurons firing that afternoon determined that choice, and the feeling of choosing was just a story my brain told itself afterward. ...

    Nature vs Nurture: What Twin Studies Really Tell Us (And What They Don't)

    When I was in college, a professor made a claim that stopped me mid-note: “Intelligence is about 50-80% heritable. Your genes, not your effort or education, largely determine how smart you’ll be.” I was stunned. And honestly, a little angry. I’d grown up believing that hard work mattered most. That anyone could achieve anything with enough effort. That your background didn’t determine your destiny. Was all of that naive? Were we just puppets dancing to our genetic programming? ...

    The Zeigarnik Effect: Why Unfinished Tasks Haunt Us

    It’s 2 AM. I should be sleeping. Instead, I’m lying in bed thinking about that bug I almost fixed. I know exactly where the problem is. I know how to solve it. I just ran out of time. My brain won’t let it go. Or that blog post I started writing three days ago. I have the outline. I wrote the intro. But I haven’t finished it, and it’s nagging at me every time I sit down to work. ...

    The Replication Crisis: Why Psychology Research Is Broken (And What It Means For You)

    I was reading a psychology paper that promised to change how I thought about willpower. The study claimed that ego depletion-the idea that willpower is a limited resource that gets exhausted-had been proven through rigorous experiments. Hundreds of studies supported it. It was taught in psychology courses. It was in textbooks. I built my productivity system around this concept. I scheduled important decisions for the morning. I avoided making choices when I was tired. I believed willpower worked like a muscle that could be depleted. ...

    Are Personality Tests (Myers-Briggs, Enneagram) Scientific BS?

    “I’m an INTJ, so I prefer working alone. That’s just how my brain is wired.” I’ve heard variations of this hundreds of times. In job interviews. In team retrospectives. In dating profiles. In therapy sessions. Myers-Briggs (MBTI), Enneagram, DiSC, StrengthsFinder-personality tests are everywhere. Companies use them for hiring. Therapists use them for counseling. People use them to explain their behavior, predict compatibility, and justify their preferences. But here’s the uncomfortable truth I’ve discovered after diving deep into the research: ...

    Loss Aversion: Why We Fear Losing More Than We Enjoy Winning

    I once turned down a $40,000 freelance contract because I was afraid of losing my $80,000 salary. The math was simple: take the contract, it would take 3 months, that’s $160k annualized. Way better than my salary. But my brain didn’t see “$160k potential.” It saw “giving up the guaranteed $80k.” The fear of losing my steady paycheck was stronger than the excitement of potentially making more. I said no. The person who took the gig finished it in 2 months, got referred to three more clients, and now runs a six-figure freelance business. ...

    Authority Bias: The Milgram Experiment Explained

    I once deployed code to production because a VP told me to, even though I knew it would break things. I was a junior engineer. They were a VP of Engineering. They said, “Ship it now. We need this for the demo tomorrow.” I tried to explain: “The tests are failing. The database migration isn’t ready. This will cause data corruption.” They responded: “I understand your concerns, but I’ve been doing this for 20 years. Trust me. Ship it.” ...
