Humans often believe that having more information always leads to better decisions. However, this isn’t always true. The tendency to seek excessive information even when it doesn’t improve outcomes is called Information Bias.

1. What Is Information Bias?

• The tendency to overvalue information and assume it improves decision quality.
• People often gather more data than needed, even if it doesn’t change the decision.
• This bias can appear in business, healthcare, investing, and daily life.

2. How Information Bias Works

• Illusion of Control: More information makes people feel confident, even if irrelevant.
• Overthinking: Gathering excessive data can slow decisions without improving accuracy.
• Preference for Certainty: Humans dislike ambiguity and try to reduce it with more information.
