Inquiries impact your credit score negatively not because you took on more credit, but because you (most likely) didn't.

The correlation is that if you get rejected by lender A, and try a new application at lender B, and again at lender C, you will have a lot more inquiries than some-one who got credit extended at the first try. FICO don't know if you actually got rejected, or if you were just checking rates, nor do they know what the reason for rejecting you was (maybe they don't even serve your area but their funnel doesn't filter on that early enough) - they just know you were checked.

This particular one is a bit iffy, my bank's UI essentially tricked me into a credit check. Then again, all of them are quite iffy and based on a few datapoints that FICO has access to, which omits many of the things you'd look at during any kind of manual underwriting.
