What leads to confirmation bias in data collection?

Confirmation bias shows up in data collection when researchers let their own beliefs or expectations steer what data they gather and how they interpret what they find. If someone strongly believes a result will be true, they may seek out sources that support that belief, overlook evidence that contradicts it, or use measurement methods that produce confirming outcomes. This self-reinforcing loop can skew the data toward what was hoped to be true rather than what is actually present. In contrast, randomly selecting data sources helps prevent this bias because it aims to create a representative sample rather than a sample that only confirms a preconceived idea. That’s why the idea that random data sources lead to confirmation bias isn’t accurate; random selection tends to reduce bias. The situation described in practice would be more about how beliefs shape the data collection process rather than about objective or accurate results, which would not inherently cause bias.
