Separating who administers treatment from who assesses outcomes helps prevent bias from shaping results. If the same person both treats and tests, their expectations or care behaviors can unintentionally influence how outcomes are observed or recorded, leading to biased conclusions. Keeping testers independent or blinded to treatment allocation preserves objectivity and strengthens the study’s credibility. In practice, this means using different people for delivering the treatment and for evaluating the results, or ensuring the tester doesn’t know which treatment was given. While there are circumstances where full separation isn’t feasible, the guiding idea is to avoid letting the treater also act as the tester to maintain valid, trustworthy findings.
