Keeping participants from knowing the true purpose of the observation is the best way to make it less likely that they will be influenced by demand characteristics. This way, they are less likely to try to guess what the researcher is looking for and give answers that they think are expected or desired. Additionally, randomly selecting participants from the population can also help to reduce demand characteristics, as it reduces the likelihood of the researcher selecting individuals who have specific biases or motivations. Paying participants for their participation and requiring them to sign their name to each survey are not as effective at reducing demand characteristics as these methods do not directly address the issue of participant biases.
