presentation and interview practice

What makes interviews and presentations hard isn't missing knowledge, it's thinking on your feet under pressure. Recovering from the "I never thought about this" moment takes reps, and those reps come from speaking on topics you didn't choose.

Pull one topic a day and talk for 5 minutes: your structure builds itself, your openings and closings become automatic. It's also a perfect warm-up right before a presentation; it opens the voice and sets the tempo.

• Implementation intentions, Gollwitzer: saying 'if X happens, I'll do Y' instead of just 'I'll do it' dramatically raises the odds of following through. Why does tying an intention to a specific situation work so well?
• Professional jealousy: why we envy our peers and what it does to us.
• Maslow's hierarchy of needs: is it really impossible to climb to the higher needs before the basic ones are met, or can a starving artist still create?
• Rogers's unconditional positive regard: how does making love conditional shape a child? What does conditional love break in us once we grow up?
• The IKEA effect: why do we find things we made with our own hands more valuable than they really are? How does effort inflate an object's worth in our eyes?
• The overjustification effect: attach an external reward to something we do for pleasure, and the motivation drains away. Is this why people who turn a hobby into a job so often fall out of love with it?
• Freud's defense mechanism of repression: is it truly possible to forget a painful memory entirely, or does that memory just come out somewhere else?
• What is it like to be a slow thinker in a world that rewards quick wit?
• Sometimes a doctor saying 'you'll get better' works almost like the medicine itself; even a sugar pill can dull real pain. How does belief turn into actual chemical change in the body? How far can expectation steer biology?
• Post-decision dissonance: after agonizing between two options and picking one, why do we start praising our choice and running down the one we left behind? Does deciding really bring relief?
• Only the person who has faith in himself is able to be faithful to others.
• Deaf signers dream in sign language and carry out their 'inner speech' with their hands, without any sound at all. The inner voice isn't necessarily a voice; it's language itself. What does thinking actually require: sound, words, or just a structure, a grammar?
• Brotherly love is love for all human beings; it is characterized by its very lack of exclusiveness.
• The halo effect: when we find someone attractive or friendly, why do we assume they are also smart and honest? How does a single positive impression color our entire judgment?
• The generation effect: we remember an answer better when we produce it ourselves than when we read it ready-made. Why does struggling write things into memory?
• You look at a wedding photo years later and remember what's in the picture, not what you actually felt that day. Sometimes the photo devours the memory. Does recording a moment get in the way of living it and remembering it?
• Flashbulb memories: we recall the moment we heard big news with photographic clarity, yet that clarity is often deceptive. Why can the memories we trust most be wrong?
• Just as you drift into sleep you jolt awake, as if falling. You're lying perfectly still; you're not falling anywhere. Why does the brain invent a danger alarm right as the body relaxes? Some say it's a reflex left over from ancestors who slept in trees.
• The 36 questions experiment: strangers who answer a set of increasingly personal questions together can develop closeness, even love. Is intimacy woven slowly over time, or built in a moment of the right shared vulnerability?
• In Dweck's research, telling children 'you worked so hard' instead of 'you're so smart' made them more resilient. Why does the way we are praised shape how we handle failure?
• The self-fulfilling prophecy: how does believing something trigger the very behavior that makes it come true? Does a teacher's faith in a child actually change that child's success?
• If I am what I have and if I lose what I have who then am I?
• Cognitive dissonance: why does it bother us when our behavior clashes with our beliefs, and why do we bend our opinions to make the discomfort go away? What is a smoker really doing when they say 'my grandfather smoked and lived to ninety'?
• Working memory: how many things can we hold in mind at once? How does this mental scaffolding let us reach the end of a sentence without forgetting how it began?
• The spacing effect: why does spreading study across several days beat cramming it all into one night? What exactly does the brain do with the time in between?
• Two people with different mother tongues can hear the same music differently; speakers of tonal languages like Mandarin develop absolute pitch far more often. The language you speak tunes your ear. Is language a lifelong ear-training course, or is a musical ear something you're born with?
• Get sick after one particular meal and even the name of that dish can turn your stomach for years; yet you never blame the dozens of other things you did that day. How does the brain decide, from a single trial, which suspect is guilty, so quickly and so stubbornly?
• Deindividuation: why do people in a crowd, or behind a mask, do things they would never do alone? Does anonymity loosen our moral brakes?
• The Zeigarnik effect: waiters remember the unpaid bills and forget them the moment they're settled. Why does an unfinished relationship or an unsaid sentence take up so much more space in the mind than anything completed?
• Hedonic adaptation: the new phone, the new home, the new relationship... every joy becomes our new normal within months. If no choice makes us permanently happy, what is choosing even for?
• The bystander effect: if someone faints in a crowded place, why does nobody move, when the same person would rush to help if they were the only witness? Why do crowds make us passive?
• Semantic and episodic memory: is 'Paris is the capital of France' stored in a different system than 'I went to Paris last summer'? Are knowing and remembering different things?
• The endowment effect: why does something suddenly become more valuable the moment it's ours? Why do we ask more for an item we're selling than we would ever pay to buy it?
• Religion would thus be the universal obsessional neurosis of humanity.
• Love for the helpless one, love for the poor and the stranger, are the beginning of brotherly love.
• People fluent in a foreign language say that swearing, or saying 'I love you', comes easier in it; the words don't carry the emotional charge of the mother tongue. A learned language becomes a kind of emotional armor. Why are we braver and more cool-headed in a foreign language?
• The mind reading distortion: assuming the person across from you is judging you. With no evidence at all, why are we so sure we know what others are thinking?
• If the use it or lose it theory of the brain is right, what will outsourcing our thinking to AI do to our minds over a lifetime?
• A crowd watches someone collapse and nobody steps in; everyone assumes somebody else will. Why does a crowd reduce helping instead of multiplying it? When 'someone' is around, why does 'I' disappear?
• The framing effect: 'ninety percent survive' and 'ten percent die' describe the same fact, so why do they lead to different decisions? Is how information is presented as important as the information itself?
• Maslow's self-actualization: living out your full potential. How many people actually reach that step, and how many stay stuck on the lower rungs?
• There is no meaning to life except the meaning man gives his life by the unfolding of his powers.
• Immature love says: 'I love you because I need you.' Mature love says: 'I need you because I love you.'
• Most of us talk to ourselves inside our head; we hear a voice when we think. But some people have no inner voice at all and think without words. What is thinking like without the inner monologue? Do we need language to think, or is language just the outfit thought puts on?
• The Yerkes-Dodson law: performance drops when arousal is too low and again when it is too high, peaking somewhere in the middle. Why does a little excitement help you while a lot of it paralyzes you?
• The feeling of knowing: even when we can't answer a question, we can sense in advance whether we would recognize the answer. Where does that inner hunch come from?
• State-dependent memory: we recall something better when we return to the mood we learned it in. Is our internal state itself a retrieval cue?
• What happens when you discover that something you have done your whole life is wrong?
• The Romeo and Juliet effect: the more the families oppose a relationship, the more devoted the couple becomes. Does the obstacle genuinely deepen the love, or just fuel the defiance?
• Ainsworth's secure attachment: the child is upset when the mother leaves and soothed when she returns. Why do securely attached people worry less in their relationships?
• You miss a place, you go back, and it's no longer the place in your memory; it has shrunk and turned ordinary. What changed isn't the place but the meaning you gave it. Is what we miss a real location, or a time that no longer exists?
• Religious doctrines are all illusions and insusceptible of proof; no one can be compelled to think them true, to believe in them.
• Everything that irritates us about others can lead us to an understanding of ourselves.
• The most important sphere of giving, however, is not that of material things, but lies in the specifically human realm.
• Repeat a word forty times in a row and it suddenly sheds its meaning, collapsing into a pile of noise. The word didn't change and neither did you. What exactly got lost in that moment? Does meaning live in the thing itself, or in a temporary stamp of approval from the brain?
• Orientational metaphors: why is good always 'up' and bad always 'down'? When spirits are 'high' or someone feels 'low', why do we pin emotion to a direction in space?
• I do not want children. I do want children. How can a person actually know whether they truly want to become a parent?
• The fundamental attribution error: when someone else messes up it's their character, when we mess up it was the circumstances. Why do we judge the same behavior so differently depending on who did it?
• The just-world belief: how does the idea that 'everyone gets what they deserve' sometimes lead us to blame the victim? What does believing the world is fair stop us from seeing?
• On exams they tell you 'never change your first answer', yet people change it anyway and usually regret it. We fall into the same trap again and again. Why are finding the right answer and trusting it two such different skills?
• Analytics dashboards turn creativity into constant self-surveillance, checking numbers becomes checking your own worth.
• To have faith requires courage, the ability to take a risk, the readiness even to accept pain and disappointment.
• Algorithm anxiety, what it does to a person to build their work life around a recommendation system they cannot see, question, or appeal to.
• Attachment styles: the anxiously attached person fights for closeness while the avoidant one suffocates in that same closeness. Why do these two keep attracting each other while running from each other at the same time?
• The false belief test: a child watches Sally leave her marble in a basket, then sees it moved while she's away. Can the child predict where Sally will look for it? Exactly when does this ability switch on?
• Wanting to master many things while knowing one lifetime is not enough.
• Levels of processing: we remember information better when we process its meaning rather than just its sound. What does 'studying with understanding' actually change in the brain?
• Personalization: taking everything as being about you. Why do we treat someone else's bad mood as our own fault?
• Diffusion of responsibility: how dangerous is the thought 'someone else will take care of it'? As the crowd grows, why does each person's share of the responsibility seem to shrink?
• Social comparison theory: why do we constantly measure ourselves against other people to know where we stand? Does our happiness depend less on what we have and more on our position relative to those around us?
• Curating your media diet like a nutrition plan, whether deliberate consumption is genuine self-care or just another optimization trap.
• Anchoring: why does the first number we hear pin down all our later estimates? In a negotiation, why does the side that names a price first hold the advantage?
• A story you're forced to abandon halfway sticks in your mind far longer than one that reaches its ending. Curiosity creates an almost bodily tension, a hunger for information. Why is not knowing sometimes a stronger drive than knowing?
• Sleep and memory: why does the brain replay what we learned during the day while we sleep at night? If you want to remember something, which matters more, studying or sleeping?
• Choice overload: why do more options leave us less happy and less decisive? Faced with endless choice, why do we sometimes prefer not to choose at all?
• As a child, one summer felt endless; now a whole year flies by. Yet the clock still ticks at the same speed. If time itself hasn't changed, what exactly is speeding up: the life we live, or the mind that measures it?
• Beck's cognitive distortion of catastrophizing: spinning a small mistake into the worst-case scenario. Why does the mind rehearse the most terrifying ending instead of the most likely one?
• Everyone in the group gives the wrong answer, and even though you know the right one, you go along with them. You report what the majority says, not what your own eyes see. Why does standing alone weigh heavier than being wrong?
• 'Should' statements: the pressure of 'I should have done it this way'. Do the rigid rules we set for ourselves motivate us or just make us feel guilty?
• The fact that millions of people share the same vices does not make these vices virtues.
