We want the public record we publish to be usable by everyone. This page explains the tools we build in and how to reach us if something gets in your way.
Open the accessibility button in the bottom-right corner of any page to adjust how the site looks and behaves. These tools run entirely in your browser. We do not use a third-party overlay, and your preferences are stored only on your device.
Increase or decrease text from 90% to 150% across the whole site. Your choice is remembered on this device.
Stronger text and border contrast for easier reading in bright conditions or for low-vision users.
Turns off animations and transitions for anyone sensitive to movement.
Switches to a more legible typeface with wider letter and word spacing.
Every link and control is reachable with Tab and Enter, with a clear, always-visible focus outline.
We aim to meet the spirit of the Web Content Accessibility Guidelines (WCAG) 2.1 at level AA. That means readable contrast, text that scales, content that works with a keyboard and a screen reader, and clear, plain language. Accessibility is part of our review process, not an afterthought.
If any part of this site is hard to use, please tell us. Email accessibility@humansignalindex.org with the page address and a short description. We treat accessibility reports as a priority and will respond with a plan to fix the issue.
