Disclosure effectiveness measured

Disclosure effectiveness measurement is the mechanism by which a financial product proves its disclosures actually work — not just that they exist. ISO 25010:2011 §4.2.4 (usability quality characteristics) treats measurability as a component of quality assurance. A product that ships TILA disclosures, fee tables, and a dispute notice but never tracks whether users view or engage with them cannot demonstrate "clear and conspicuous" compliance under CFPB standards — because clarity is a function of user comprehension, not document presence. Analytics on disclosure pages also surface the difference between required content that users find helpful and content so buried that it functions only as legal cover.

Wrap all compliance-critical disclosure sections in a shared component that fires analytics events on mount. In src/components/DisclosureSection.tsx:

// src/components/DisclosureSection.tsx
import { useEffect } from 'react'
import { trackEvent } from '@/lib/analytics'

export function DisclosureSection({ id, title, children }: {
  id: string
  title: string
  children: React.ReactNode
}) {
  useEffect(() => {
    trackEvent('disclosure_viewed', { disclosure_id: id, title })
  }, [id, title])

  return (
    <section className="disclosure" aria-labelledby={id}>
      <h2 id={id}>{title}</h2>
      {children}
    </section>
  )
}

Use this component for every fee schedule, APR block, TILA section, and dispute notice. Review the disclosure_viewed event data quarterly to identify disclosures with low view rates and move them higher in the page.
