How we score a locality, and what we refuse to fake

People ask, reasonably, where our numbers come from, and why they should trust a safety score or a water reading from a young company they have never heard of. It is a fair question, and the honest answer is more useful than a slogan. So here is the whole method, including the part almost every product in this space quietly hides: what we do when we simply do not know.

Three kinds of source, never just one

For every locality we build a reading from more than one direction. There are official and public records where they exist, for things like policing, civic works and water. There are on-the-ground checks that no dataset contains, like the real walk to the nearest metro along a route a person would actually take. And there is what residents themselves say, in their own words, on public forums where they have no reason to flatter the place. A number that survives all three is worth something. A number that rests on one is a rumour with a decimal point.

The interesting cases are when the sources disagree, and they often do. We do not quietly average a conflict into a smooth middle number and move on, because that hides exactly the thing you would want to know. Instead the disagreement itself becomes information: it lowers our confidence in that reading, and we say so on the page, rather than laundering doubt into false precision.

What we will not do

• Invent a figure to fill a gap. If we do not hold a reading for something, the report leaves it blank and tells you it is blank, instead of guessing and hoping you never check.
• Round the uncertainty away. Every score carries a confidence flag, High, Medium or Thin, so you always know how hard the number can bear your weight before you lean on it.
• Let anyone pay to move a score. The ranking is not for sale, to a builder, a broker or an owner, because the moment it is, every other number on the site is worthless too.

We know a blank space looks worse on a marketing page than a bold, confident number, and a rival will always be happy to print the confident number. We think the blank is better for you, because a made-up figure you cannot check is precisely the thing that got you burned the last time you trusted a listing, and printing one more would just make us part of the problem we started this to fix.

This is not modesty for its own sake. It is the whole product. The only reason to use Locara over the portal you already have open is that our numbers are ones you can act on, which means they have to be honest about their own limits. A confident wrong figure quietly makes the decision for you and hides that it did. An honest range, flagged for what it is, hands the decision back to you, where it belongs.

A score you cannot trust is worse than no score at all.
