High
The pull has to be there, and you've stopped trying to argue yourself out of it — probably because you've tried and it didn't take. There's more honesty in that than in the profiles that call attraction a bonus, and it protects you from a specific unhappiness: the sensible relationship everyone approves of and nobody inside enjoys. The thing worth knowing is when this bar does its work. Pull is loud at the start and quiet later, so a high standard here selects hardest at the moment you know least about who the person actually is. It isn't a bar that needs lowering. It's a bar that works better with a month between the pull and the decision.
Moderate
You want to be drawn to someone without needing to be knocked over. Attraction has to be somewhere in the picture, and it doesn't have to arrive in the first ten minutes — the pull that builds over a few meetings counts with you just as much as the one that shows up instantly. That is the most durable version of this standard, because it uses attraction as information rather than as a verdict. The place it costs you is the beginning. Deciding whether a moderate pull is the kind that grows or the kind that stays moderate is genuinely hard, and this bar makes you do that work case by case rather than handing you a fast answer either way.
Low
Attraction isn't your gate. It's welcome when it's there, but its absence doesn't end anything, and you're capable of the thing many people say is impossible — growing into wanting someone whose company came first. That is a real advantage: pull is the fastest-moving of the three standards, loudest exactly when you know the person least, and a low bar here immunises you against the specific mistake of reading chemistry as compatibility. The cost is quieter and arrives later. A relationship where attraction was never really present doesn't usually fail; it goes flat, and flatness is harder to name out loud than a problem, so it tends to get carried for years before anyone says it.
