THE NOISE WE SORT THROUGH
Three articles, each with every point looked into, its source, and our reading. Open any of them and make up your own mind.
SERIES · WHO SAID IT
Fifteen famous lines checked. Six belong to somebody else, two are genuine, and six are real but trimmed or misquoted, including three well-known lines from film and fiction. One is an origin story with no source.
SERIES · REAL OR MYTH
Fourteen popular claims, checked one at a time. Nine are myths, three are partly true, one cannot be settled, and one holds up.
PHILOSOPHY · WITH THE PASSAGES
Eight common fears, each with the passage a Stoic wrote about it: book and section, in a translation you can read free, so you can check it in context.
ABOUT HACKS VITAE
There is a lot of noise out there: advice, quotes and "facts" repeated so often they start to feel true. We go back to the sources, sort what holds up from what doesn't, and show you the research, then turn what holds up into something useful: habits, systems, workflows and ideas you can act on. You make up your own mind.
