Final answer:
The statement is false; the correct term for an experiment carried out without people knowing they are part of it is naturalistic observation, which allows for the collection of data in a natural environment to increase ecological validity.
Step-by-step explanation:
An experiment that is carried out without people knowing they are part of it is called a naturalistic observation, not a naturalistic experiment. Therefore, the statement is false. Naturalistic observation is a research method commonly used by psychologists and other social scientists. This technique involves observing subjects in their natural environment. This type of research is often utilized in situations where conducting lab-based research is unrealistic, cost prohibitive, or would unduly affect the subject's behavior.
Blind experiments, on the other hand, are scientific experiments in which subjects do not know in which experimental group they have been placed. This is done to help avoid bias in the outcome. When the people scoring the tests are also unaware of the group assignments, this is referred to as a double-blind study and helps control for experimenter bias.
The validity, or accuracy, of information collected through naturalistic observation is often higher due to the increased ecological validity or realism of the setting. The behavior observed is more likely to reflect natural behavior because it is unobtrusively recorded in a real-world environment. Thus, naturalistic observation is valued for the honesty of the data collected in a realistic setting.
