Final answer:
The principle of research that indicates that researchers should not engage in practices that risk participant well-being is known as the no harm principle.
Step-by-step explanation:
The principle that states researchers should not engage in any practices that may risk the well-being of participants is known as no harm. This ethical principle is paramount in research involving human subjects. Informed consent is a process where participants are fully informed about the study's purpose, procedures, risks, and benefits, and voluntary consent is obtained. Still, it does not, in itself, ensure that no harm will come to the participants. Debriefing is a process that takes place after the experiment has ended, where participants are informed about the true nature of the study, especially if deception was used. Confidentiality is about ensuring that the data collected will be kept private and participants will not be personally identifiable based on the results. However, it is the no harm principle that is specifically aimed at protecting participants from physical, psychological, or emotional harm during the research process.
