Plain answers about hyperfocus, flow and deep work — what the research actually shows, where it runs out, and where HYPER fits.
- What is hyperfocus?How researchers define and measure hyperfocus, and what is still unknown about how long it lasts, what the brain does and whether it can be triggered.
- Hyperfocus vs flow: are they the same thing?Researchers disagree on whether hyperfocus and flow are one state or two; here is what each side argues and what the thin data show.
- How to protect a deep-work sessionDecide the one thing, let messages wait, catch stray thoughts, make leaving deliberate and mark the way back in, with what the research does and doesn’t show.
- Why streaks can backfire when work comes in surgesWhat a streak counter actually measures, and HYPER’s stated reasons for keeping none — a design position, with no research claims.
- HYPER, Forest, Opal and Focusmate: how do they differ?Forest grows a tree, Opal blocks apps, Focusmate finds you a partner, HYPER keeps a ritual and a record: a dated, sourced comparison by HYPER’s maker.
How these pages are sourced
Every research claim on these pages comes from HYPER’s evidence ledger: 141 claims about hyperfocus and the research around it, each one read at its original source, recorded with how the study was done, and kept together with its caveat. If a claim isn’t in the ledger, these pages don’t make it.
The caveat travels with the claim. A finding from 85 students is described as a finding from 85 students. A proposal is called a proposal. A number that can’t be traced to a validated measurement isn’t repeated, however often it circulates.
The ledger also keeps a list of claims we refuse to make — popular lines about hyperfocus that the sources don’t support. Many of the most-repeated lines about hyperfocus are on that list, which is why these pages say “nobody knows yet” more often than most.
And one line is kept apart from all of it: that going deep is worth protecting is HYPER’s conviction, not a research finding. Where a page argues a position rather than reporting evidence, it says so at the top.
