Pay transparency laws were supposed to fix this. Read the fine print.

Over the past few years, most of the states clinical research workers live in started requiring employers to post salary ranges in job ads. It sounds like the end of pay secrecy. The research on what these laws actually did is more sobering, and it matters for how much you can trust a posted range when you see one.

Where the laws are

As of 2026, 18 states plus Washington, DC have enacted pay-transparency laws, and a growing set require an actual range in the job posting. Colorado went first, on January 1, 2021. California and Washington followed on January 1, 2023; New York City in late 2022 and New York State in September 2023; Illinois in January 2025. Virginia's took effect July 1, 2026, with Ohio's Columbus and Delaware close behind. If you apply for clinical research roles in these states, employers are legally required to show you a range.

What the ranges actually did

Here is where the optimism meets the evidence. A study of Colorado's first-in-the-nation law, using millions of job postings, found it raised the share of postings that disclosed pay by about 30 percentage points, a real gain, but with substantial non-compliance remaining. And for employers who posted before and after, posted salaries rose only about 3.6 percent on average. The law revealed pay; it did not meaningfully raise it.

Worse, the disclosure is often too vague to use. Because the laws say little about how wide a range can be, employers post enormous ones to technically comply. A 2026 Cornell analysis of roughly 10 million postings found that these very wide ranges actually deter female applicants and dampen negotiation: when the range is huge, applicants cannot tell where they realistically stand and negotiate less assertively. A posted band of, say, $70,000 to $180,000 satisfies the law and tells you almost nothing.

What this means for you

The practical lesson is to treat a posted range as a legal minimum of disclosure, not as real salary intelligence. A tight range on a posting is genuinely useful; a range wide enough to fit three career levels is compliance theater. When you see one, look at its width before you trust it, and know that the midpoint is not a promise. The transparency laws made pay visible in the technical sense without making it legible in the useful sense.

This is, in a way, the whole thesis of the site playing out in public policy. Even a government mandate to disclose pay produces ranges too coarse to negotiate against, for the same reason the salary aggregators are: a number without a tight level and a real sample tells you little. The fix is the same everywhere. Precise, level-specific, real numbers beat wide, blended, technically-compliant ones.

What the posted range cannot tell you

A posted range tells you the band an employer will admit to in a state that forces it. It cannot tell you where in that band a specific role actually lands, what the person hired last year got, or what the number is in the states with no law at all. That precision only exists if workers share what they were actually paid, at what level. If you have seen the gap between a posted range and a real offer, add your datapoint, and make the disclosure mean something.
