The Saying-is-Believing Effect is a cognitive bias where individuals interpret information in a way that aligns with statements they have previously made. Essentially, once someone expresses an opinion or forecast, they are more likely to filter new information to support that position. In data analytics and business intelligence, this bias can subtly distort decision making.…
