Stage 8 of LOGOSGBITS — the capstone: seven trials in finding the fault in an argument without first having to build the argument that would replace it. A term arriving from nowhere, a conclusion outrunning its premises, an argument run backwards against its own arrow, a middle term joining nothing — and one case, well chosen, that ends a universal claim for good. Each check names what was missing — and that is where correction begins.
Each trial is locked until you clear the one before it. Every level scores out of 1000 — 600 for accuracy, 400 for speed — so speed alone can't clear the bar; you have to solve most problems, and quickly. Reach 650 to unlock the next.
You can find the fault in an argument in seconds without building its replacement — a term with no source, a conclusion broader than its evidence, a conditional taken the wrong way round, a middle term that only repeats — and you can end any universal claim with a single well-chosen case. Eight stages from the first definition to the last audit: that is LOGOSGBITS.
These checks are not a licence to dismiss. Each one names what an argument lacked — a term with no source, a link never made, an ending that could have arrived another way — and naming the lack is where the better argument starts. You learn to reject quickly so that your effort goes to the reasoning that deserves it.
