Impostor contributors threaten the integrity of well being analysis, and by extension, the insurance policies and medical selections constructed on it, warn consultants in The BMJ right now.
Eileen Morrow and colleagues on the College of Oxford say the analysis group “must acknowledge the problem and dedicate resources to testing and implementing safeguards… to ensure that the data guiding clinical care reflect the real patient voice.”
Impostor contributors are people who present misleading or inaccurate information with a view to participate in well being analysis, or automated pc bots that mimic human habits and responses.
The difficulty has grown in recent times as on-line recruitment has grow to be central to fashionable well being analysis and might affect all sorts of research, from surveys to randomized managed trials.
The motivations of impostor contributors stay unknown, clarify the authors. Though some stories counsel that financial profit is a driver, not all research provide monetary incentives, so different motives, similar to boredom, curiosity, and even an ideological intent to disrupt analysis, may additionally play a task.
But their affect is demonstrable. A 2025 evaluation confirmed that 18 of 23 research in search of impostor contributors of their information units discovered them, with charges starting from 3% to a excessive of 94%.
Researchers ought to routinely combine impostor participant detection and prevention into on-line analysis, whereas contemplating the potential impact on their research inhabitants, write the authors. Frequent safeguards embrace id verification procedures or CAPTCHA assessments (asking contributors to finish a activity similar to to learn and kind distorted letters).
At a minimal, they are saying, research ought to transparently report which safeguards have been used and acknowledge their limitations, and journals ought to encourage constant and clear reporting of those safeguards.
Funders and establishments must also spend money on infrastructure and coaching to assist researchers maintain tempo with evolving ways, whereas clinicians and policymakers needs to be cautious when decoding research that use on-line recruitment if impostor participant prevention is just not talked about.
They conclude, “Impostor participants are more than a nuisance; they are a systemic threat to health research. Their effect is demonstrable and their detection inconsistent. In an age where online recruitment underpins everything from randomized controlled trials to surveys, they risk undermining the integrity of health research and the decisions built on it.”
