<b>YMYL is a spectrum with a multiplier, not a category you're in or out of</b>

The question: is a page either YMYL or not, like a checkbox?

The guidelines describe it as a gradient. Per the QRG's treatment of Your Money or Your Life topics, a page can be 'clearly YMYL,' 'possibly YMYL,' or 'clearly not YMYL,' and raters are told to consider the potential to cause harm — to the individual, to other people, or to society — as a matter of degree. A page on choosing running shoes is low on the spectrum; a page on medication interactions is at the ceiling.

The operational consequence is a multiplier effect. The standard of trust required does not switch on; it scales with potential harm. The same thin author bio that is acceptable on a hobby-craft page becomes disqualifying on a page about cancer treatment, because the cost of being wrong differs by orders of magnitude.

Supporting evidence: the four harm types in the guidelines — health/safety, financial, civic/societal, and 'other' high-stakes — give raters a structured way to place a topic on the gradient rather than sorting into two bins.

Counter-evidence and caveat: this is the rater's framework. We have no public confirmation that systems compute a continuous YMYL harm-score per query. They may use topical classifiers that behave more like coarse buckets.

What we still don't know: where the boundaries sit for ambiguous topics — pet health, amateur legal advice, nutrition for general wellness. These sit in the murky middle of the spectrum and almost certainly get inconsistent treatment.
