public speaking practice

The only real cure for stage fright is talking a lot in a safe place. In a room where nobody is listening, with a timer running, out loud. Your brain only learns "speaking is not dangerous" through repetition.

The topics below are picked for starting out: things you already have opinions about, nothing that makes you sweat. Speak about one every day; you'll hear the difference in two weeks.

pull today's topic

• The odds of you existing were practically zero; you happened only through countless accidents stacking up just right. Given such an impossible stroke of luck, is living an ordinary life a waste of the universe's gift, or is even thinking that way an empty vanity?
• Why do some of the kindest, most honest people struggle in life while people who lie and cheat seem to thrive?
• Diffusion of responsibility: why does nobody in a crowd step in to help, with everyone assuming someone else will? Why does individual conscience weaken as responsibility gets spread across more people?
• Diogenes living in a barrel and telling Alexander the Great to stop blocking his sunlight: what Cynic philosophy asks of us.
• The Stoic divide between what is up to us and what is not, and where inner peace really comes from.
• Moral relativism: do right and wrong change from culture to culture, or is there a universal standard? When what is normal in one society is horrifying in another, who is right?
• Children who are taught philosophy improve at math, reading, and empathy. Why is philosophy still missing from most schools?
• A single idea can change the course of a life. Which ideas have that power?
• Buridan's ass: a donkey standing exactly halfway between two identical bales of hay cannot decide which one to choose and starves to death. Does perfect equality really paralyze free will and make decision impossible?
• The ship of Theseus: if every part of the ship is replaced over time, is it still the same ship? Our cells are replaced too, so what keeps us the same person?
• The trolley problem: a runaway trolley is about to hit five people; pull the lever and it switches tracks, killing one person instead. Is deliberately killing one person morally different from letting five people die?
• If you felt no pain, and no hunger even while starving, survival would become impossible. Maybe pain is not a flaw but the very thing that ties you to yourself. Would a being that never suffers really count as alive?
• To be happy, you have to stop thinking about happiness; chase it directly and it runs away. Maybe the things we want most only arrive once we stop wanting them. Is desire, then, something that sabotages itself?
• In a relationship, is it more important to be loved or to be understood?
• What is the real difference between justice and revenge?
• The first time you learn something, the world changes; you can never return to the person who did not know it. Some knowledge remakes you irreversibly. If you could have chosen never to learn, would you have wanted to stay your ignorant former self?
• Schopenhauer's hedgehog dilemma: hedgehogs huddle together for warmth in the cold, but their spines force them apart, and then the cold pushes them back together. Since human closeness brings both warmth and pain, are we all endlessly searching for that ideal distance?
• Utilitarianism: should the greatest happiness of the greatest number be our measure? If one person's suffering can be traded for the majority's happiness, what happens to justice?
• Is beauty objective or subjective?
• The trolley problem: is it right to pull the lever and sacrifice one person to save five? Why does actively killing one feel heavier than standing by while five die?
• What do you think happens after we die?
• The infinite monkey theorem: would a monkey hitting random keys for an infinite amount of time eventually type out the complete works of Shakespeare, letter for letter? Does infinity turn the seemingly impossible into a certainty?
• The face you see in the mirror is not your face; it is flipped left to right. In photos you look wrong to yourself because you are used to the mirror. So which one is your real face? Have you never actually seen yourself correctly, and can only other people see you?
• Is a hot dog a sandwich? Commit to a definition and defend it, then explain why people get so emotionally invested in categories.
• Isn't it strange how a smell can suddenly throw you years back, into a moment you thought you had forgotten? You never lost that memory; it was waiting for a door to open. Is forgetting really erasing something, or just losing the path to it?
• Nozick's experience machine: imagine being plugged into a simulation where you would believe you were living a perfectly happy life, getting everything you ever wanted, except none of it would be real. Would you plug in, or choose reality with all its pain?
• Brain rot, whether a steady diet of low-quality content actually changes how our minds work or just gives us a word for old guilt about wasted time.
• We see a face in a cloud, a startled expression in a wall socket, a figure in the dark. Why does the brain insist on finding faces even in random blotches? Why is seeing a face that isn't there less risky than missing one that is?
• Are things in the world actively getting worse, or is that just what getting older feels like?
• People in their thirties often talk about the price they paid for being lazy in their twenties. Which habits actually compound over a decade?
• Confirmation bias: once we believe an idea, why do we start seeing only the evidence that supports it? How does the mind filter the world to prove itself right?
• Before you learn a word, its concept is a blur; afterwards you suddenly see it everywhere. Hear 'schadenfreude' once and you start spotting it in everyone. Does the word create something new, or reveal what was always there? How many things sit in plain sight, invisible, in the world of concepts we haven't learned yet?
• System 1 and System 2: you answer two times two without thinking, but 17 times 24 stops you cold. How do these fast and slow modes of thought divide up our daily decisions?
• The foot-in-the-door technique: once we agree to a small request, why are we more likely to say yes to a bigger one? How does our wish to appear consistent get used against us?
• The jam experiment: shoppers stopped to browse a display of 24 jams, but a display of just 6 sold ten times more. Why does abundance leave us unable to buy at all?
• Day job or dream: should your passion also be your paycheck?
• Rationalization: not getting what we wanted and declaring 'I never wanted it anyway'. How fast does the mind work to justify what the heart already decided?
• The tip-of-the-tongue state: we know the word but just can't get it out. What does this strange mix of knowing and not knowing reveal about how memory is catalogued?
• Career success and personal happiness often have nothing to do with each other.
• Overlearning: continuing to practice past the point of 'I've got it' makes knowledge far more durable. What separates knowing something well enough from true mastery?
• A song gets stuck in your head and loops for hours; the harder you chase it out, the harder it comes back. Why does the brain get trapped in the cycle of an unfinished melody? And why does playing it once from start to finish set you free?
• Getting older often brings a feeling of being lost. Why, and what helps?
• FOMO: the constant feeling that something better is happening somewhere else. Did social media invent this feeling, or just inflate something that was always inside us?
• Overgeneralization: turning one bad experience into 'it always goes this way'. How does a single event become a rule for your whole life?
• The serial position effect: why do we remember the beginning and end of a list better than the middle? Are two different memory systems at work?
• The framing effect: '90 percent survival' and '10 percent mortality' describe the same thing, so why do we say yes to one and not the other? How does the packaging of a fact flip a decision?
• Hearing your own voice on a recording, you say 'that's not me'; it sounds strange and foreign. Yet that's the voice everyone else has always heard. So which voice is the real you: the one inside your head, or the one the world hears?
• The forgetting curve: we lose most of what we just learned within the first 24 hours. So is forgetting a malfunction, or the brain's way of clearing out what it doesn't need?
• Chunking: why do we memorize a phone number in groups of three and four instead of digit by digit? How does packaging information let the mind hold so much more?
• Social loafing: why does everyone put in a little less effort when working in a group? Do we slack off once we sense our individual work is invisible in the crowd?
• Do adults need a best friend, or is that a childhood idea we outgrow?
• The need for competence: feeling yourself getting better at something is motivating all by itself. Are video game leveling systems tapping exactly this need?
• Realizing in your mid thirties that you no longer want the career you trained for feels like a video game where you cannot reset your skill tree. How should people think about starting over midlife?
• The grass is always greener: restless with what we have, forever suspecting something better is out there. Does that feeling push us to grow, or condemn us to never being satisfied by anything?
• How do you come to terms with getting older?
• Growth mindset and fixed mindset, Dweck: whether we believe abilities are innate or developable changes everything. Is 'I'm just not a math person' really a fact, or a cage?
• Someone across from you on the bus yawns, and you yawn. Even reading the word 'yawn' is enough. It has nothing to do with your own tiredness. Why is your body so permeable that it involuntarily mimics someone else's state?
• All-or-nothing thinking: failing once and concluding 'I'm a total failure'. Why is it so hard to see shades of gray?
• The primacy effect: why does the impression from a first meeting overshadow everything that comes after it? Why is a judgment formed at the start so hard to change?
• The reciprocity principle: why does a small favor make us feel we owe someone? Can even a free sample change what we decide to buy?
• The Von Restorff effect: we remember the item that stands out from a list better than all the others. Why is being different the easiest way to be remembered?
• The dress photo split the internet between blue and black and white and gold. What did that moment teach us about perception, and about arguing with people who literally see differently?
• How does anyone stay disciplined for years rather than days?
• The need for relatedness in self-determination theory: when people we're attached to care about something, we start caring too. Is that why falling in love with a subject so often starts with loving the teacher?
• Once you learn about something, you start seeing it everywhere; the car model you just bought suddenly appears on every street. Nothing changed in traffic; what changed is you and your attention. How much of our reality is what's out there, and how much is what we've chosen to notice?
• Social proof: when we don't know what to do, why do we look at what everyone else is doing? When would the assumption 'everyone's doing it, so it must be right' lead us badly astray?
• Regret minimization: Jeff Bezos made his leap by asking 'when I'm 80, will I regret not having done this?'. Is imagining your future regret a good compass for today's choices?
• The scarcity principle: why do we suddenly want something more when it's running out or labeled 'last chance'? How does the fear of missing out inflate desire?
• Parasocial relationships, why watching someone talk to a camera for years can feel more like friendship than many real friendships.
• The word is right on the tip of your tongue; you even know its first letter, but it won't come. If you don't know it, how can you 'almost' know it? What happens in that gap between knowing and recalling?
• Looking in the mirror you say 'this is me', but that image is the exact reverse of what everyone else sees; it's why you look 'off' to yourself in photos. Is the face we know as our own a face no one else has ever seen?
• Denial: rejecting a truth even while looking straight at it. When something is too painful to accept, how does the brain manage not to see it?
• Show people a meaningless shape and ask them to name it: the spiky one gets 'kiki', the round one gets 'bouba', all over the world, in every language. There's a hidden universal bridge between sounds and shapes. Are words purely arbitrary, or do sounds have a taste and a shape of their own?
• Is it ever too late to completely turn your life around?
• The bandwagon effect: once something becomes popular, why do we lean toward it regardless of whether it's true? Where does the assumption 'everyone's doing it, so it must be right' break down?
• 'Saudade', 'hygge', 'iktsuarpok'... some feelings take one word in another language and a whole sentence in yours. If your language lacks the word, do you never have the feeling, or do you have it and simply fail to notice it for lack of a name? Does the word create the emotion, or just make it visible?
• Intrinsic versus extrinsic motivation: do we do things for their own sake, or for a reward waiting outside? How much does it matter for learning whether you study out of curiosity or just to pass the exam?
• Procedural memory: we can't explain how to ride a bike, but we can ride one. Why can't knowledge that lives in the body be put into words?
• Bilingual children don't mix their two languages; they learn astonishingly early which language belongs to which person, speaking one with their mother and the other with their father. Even a one-year-old switches languages based on the face in front of them. How does a mind that small route languages to people so cleanly?
• Why is it so hard not to take criticism of your work personally?
