Sintesi	Deception in research—withholding information about study procedures, hypotheses, or true purpose—is ethically permissible under limited circumstances when specific criteria are met. The regulatory framework (45 CFR 46.116(a)(5) in the U.S.; APA Ethical Code Section 8.07) allows deception if: (1) it is not reasonably possible to conduct the research without deception, (2) the deception does not involve risks greater than 'minimal risk,' and (3) participants receive full disclosure and the opportunity to withdraw data after debriefing. Deception is particularly common in social and behavioral research (studying prejudice, conformity, ethical decision-making) where awareness of the true hypothesis would fundamentally alter behavior. Understanding when deception is justified and how to implement it ethically is essential for behavioral researchers.	Vulnerable populations are groups with limited capacity to protect themselves due to age, cognitive ability, institutional dependency, or social circumstances. Regulatory frameworks in the U.S. (45 CFR 46 Subparts B, C, D) and internationally identify specific vulnerable populations—children, prisoners, pregnant women, cognitively impaired individuals—and mandate additional ethical protections beyond standard informed consent. These protections include obtaining informed consent from surrogate decision-makers (parents, guardians), additional assurances of minimal risk, and enhanced monitoring for safety. Research ethics committees apply heightened scrutiny to studies involving vulnerable populations and may deny approval if special protections are inadequate.
