Sometimes a new construct is built from items that already belong to other constructs: the name is new, the items are not. The Collider helps you see whether yours is genuinely new. It compares the items you pick against every construct on the map, shows how much of your idea the constructs you borrowed from already cover, and points to the closest construct you did not borrow from, the one most likely to already be what you built.

How to read this. There are two reads, both based on meaning.
Nearest by meaning (shown the moment you pick a construct, and on every construct page) compares a construct with every other by the meaning of its written definitions, and surfaces the closest one. It works from the definitions, so every construct is covered. A single closeness number does not tell you much on its own, so what matters is the ranking. Every construct on the site has a closest match, and we show where this one falls among all of them. A match near the very top is one to read side by side, since it may be one idea wearing two names. Hold it as a prompt to compare the two meanings yourself, not proof that they are the same construct.
The panel above lets you build a proposed construct out of individual survey items, one level down. You pick items from one or more existing constructs, and your proposed construct is placed next to the constructs closest to it in meaning. Parent-coverage is the share of your proposed construct that the constructs you borrowed from can already account for on their own. The rest, the part they cannot account for, is the open space between existing constructs where a genuinely new construct could live; the nearest construct you did not borrow from is shown next to it.
This flags recombination; it never certifies novelty, which needs discriminant evidence on real data. Item wordings are illustrative paraphrases, not published scale items. Something wrong? Report it.
