Honduras's national tax administration, SAR, underwent a major internal reform to address corruption, strengthening human-resource policies and renewing most of its existing personnel. The standard communication instinct for an institution that has genuinely cleaned itself up is to announce it directly -- tell citizens the corruption problem is being fixed, so they'll trust and comply with the institution again.

Prior research on anticorruption messaging in Latin America had already documented a recurring backfire effect: citizens holding entrenched, often overly pessimistic beliefs about how corrupt an institution is tend to interpret a reform announcement as confirmation that the institution really is that bad, reinforcing the very distrust the message was meant to fix rather than correcting it.

Ajzenman, Ardanaz, Cruces, Feierherd and Lunghi ran a survey experiment testing three message types against a Honduran taxpayer sample: a 'reform' message describing SAR's anticorruption efforts alone, a 'debiasing' message using an independent, non-government source (Latinobarometro) to show Honduras's tax-agency corruption was actually among the lowest in the region, and a 'sequential' message that showed the debiasing message first and only then the reform announcement.

Debiased first with an independent survey showing the agency was already among the least corrupt, so the reform landed as confirmation, not evidence of a bad one.

A reform announcement implies the problem was serious enough to need fixing, validating pessimistic priors.

An independent benchmark shifts the reference point before the announcement, so it lands as confirmation of a clean institution.

Correcting the belief first prevents the announcement from being misread through a distorted lens.

The effect held in real tax filings, not just surveys, showing the mechanism changes actual behavior.

Before announcing a fix, correct the audience's baseline belief about the problem's severity with an independent benchmark, or the fix reads as confirmation of the problem.

In the survey experiment, the reform-only message backfired: it increased taxpayers' self-reported willingness to evade taxes by roughly 11-14 percentage points and increased dishonest behavior in an incentivized dice-game measure by about 4 percentage points over an 8% baseline, while the sequential message reduced perceived corruption and evasion willingness. 1), rising to 875,000 lempiras among taxpayers already flagged as high non-compliance risk, while the debiasing message alone produced no statistically significant effect on its own.
