Too much information
What your brain lets through, and what it quietly filters out.
What Repetition Does to Truth
Hear a claim once and you shrug. Hear it five times and it starts to feel like common knowledge, whether or not anyone ever checked it.
Why Weird Things Stick
You've forgotten nearly everything about last Tuesday, except the man on the train in the banana costume. That's your memory working exactly as designed.
The Power of Contrast
A $40 shirt feels cheap next to a $300 jacket and absurd next to a $10 one. Your brain has no absolute scale, and today we look at what that costs you.
Seeing What You Already Believe
Your brain works less like a judge and more like a lawyer: it collects evidence for a verdict it reached a long time ago.
The Mirror Problem
Everyone can name the most biased person in their office, and almost nobody names themselves. Today is about that gap.
Not enough meaning
How thin facts get padded into confident stories.
Stories from Thin Air
A coin lands heads five times in a row, and something in you whispers that tails is due. It isn't — and today is about why that whisper sounds so sure of itself.
Filling the Gaps
A name on a résumé, a white coat, a queue outside a restaurant. Today is about the details your brain invents when all it has is a label.
Loving the Familiar
A confident handshake, a logo you recognize, an idea from your own team: today is about why the familiar and the likable get graded on a curve.
Bad at Numbers
A tax refund feels like free money, a fifty feels harder to break than five tens, and "it could happen" quietly becomes "it will." Today is about the games your brain plays with numbers.
Mind-Reading Illusions
You explained it twice and they still don't get it. Today is about why the view from inside your head looks nothing like the view from outside.
Time Travel Errors
Your brain rewrites last summer, grades old decisions by how they happened to turn out, and schedules next month for a version of you who doesn't exist.
Need to act fast
Why confidence, urgency, and sunk effort steer your decisions.
The Overconfidence Engine
Ninety-three percent of drivers rate themselves above average. Meet the machinery that keeps you feeling sure of yourself and in charge.
The Pull of Now
Future-you makes sensible plans, and present-you overrules them, usually within reach of a snooze button. Today: why the nearest thing always feels biggest.
In Too Deep
Forty minutes into a bad movie, the smart move is to turn it off — yet most of us watch to the end anyway. Today is about why quitting feels more expensive than it is.
Guarding the Status Quo
The gym you never visit still bills you monthly, and the whole family is driving to a restaurant nobody actually wanted. Today is about why we defend things as they are.
What should we remember?
How memory edits the past you rely on.
How Memories Get Made
You didn't forget that name from the meeting; your brain never saved it. Today opens the final theme: what memory decides to keep, and why.
The Highlight Reel
Your memory doesn't store the meeting. It stores the worst moment, the ending, and whatever someone said about it afterward.
When Details Fade
Your memory throws away the encounters and keeps the averages. Today: where those averages come from, and why old misery loses its sting.
Editing the Past
That family story you've told a dozen times has quietly rewritten itself with each retelling. Today is about memory's edit history, and the one memory quirk worth using on purpose.
Choosing Simply
Ten biases about tidy options: why committees argue about bike sheds and why you keep requesting data you'll never use.
