Final answer:
Participant bias is one of the biggest problems in conducting psychic research as it can lead to inaccurate or skewed responses.
Step-by-step explanation:
One of the biggest problems in conducting psychic research is participant bias. Participant bias occurs when the participants in a study intentionally or unintentionally provide inaccurate information or skew their responses. This can undermine the credibility of the research results as it introduces a potential source of error.
Participant bias can arise due to various factors such as social desirability bias, where participants respond in a way they believe aligns with societal expectations, or demand characteristics, where participants respond based on cues from the experimenter. For example, in a psychic research study, participants may consciously or subconsciously provide responses that they think the researcher expects, leading to biased results.
