Answer: True
Step-by-step explanation:
Psychologists do indeed find it necessary to have to use deceit in their research to get the best response because if they do not, subjects in the research may not give the most accurate response to avoid being judged or ridiculed.
Indeed the practice is even allowed by the American Psychological Association (APA) in Ethical Standard 8.07, Deception in Research. Under this standard, deception is allowed if the study requires it. They are however to disclose this deception as quickly as possible without harming the integrity of the study.
