Asking leading questions is the most evident practice of confirmation bias. These questions lead people to a certain answer. Compare these two questions:

1. "Our previous feedback survey showed that most people prefer breakfast as their favorite meal. Do you agree?"
2. "If you had to choose just one, which meal do you prefer: breakfast, lunch, or dinner?"

The first question introduces an assumptive statement and then asks the respondent for feedback. As a result, respondents are more likely to agree with the statement.

Leading questions tends to collect bad data that can skew your research findings and lead you to incorrect conclusions.
