Ethical reviews are an integral part of psychological research, increasingly supported by digitalized platforms that guide the process from early information gathering to final feedback. Although researchers and evaluators are both primary users of said platforms, the interface between them is often characterized by asymmetry, with limited transparency regarding the rationale for evaluations and the implications of providing specific information items about the project. A transparent interface could transform ethical review into a self-auditing process, prompting researchers to reflect upon and systematically organize the ethical aspects of their projects. A common concern is that supplying transparency-related information might make the process more demanding for the user. This study reports on a test conducted during the streamlining of the platform for the Ethical Committee of the Human Inspired Technologies Research Center at the University of Padua. We tested whether integrating callouts that provide contextual definitions and procedural guidance would affect the researchers' experience during the application process. Eight participants (mean age = 31; females = 4) were randomly assigned to submit a project through a platform, either with or without the callouts. Contrary to concerns that additional instructions might impede users, the callouts appeared to enhance efficiency instead. Participants in the callouts condition completed the form more quickly (in minutes: M_control = 72.85; SD_control = 32.72 vs M_exp = 44.88; SD_exp = 21.32). They also reported higher usability (M_control = 3.3; SD_control = 0.8 vs M_exp = 4.1; SD_exp = 0.4) and transparency (M_control = 2.7; SD_control = 1.2 vs M_exp = 3.6; SD_exp = 0.9), lower negative emotions and reduced psychological reactance (M = 2.8; SD = 1.2) compared to the control group (M = 3.6; SD = 1.2). These preliminary findings suggest that applying user-centered design principles can improve ethical review platforms and foster more researcher-friendly evaluation systems.
