Confirmation bias is a cognitive bias that causes us to seek confirmation of our preconceptions, while we avoid information that might contradict them. It can also cause us to tend to overvalue information supporting our preconceptions, and undervalue information in conflict with them.
Last time, we explored indicators that confirmation bias might be taking place. Let's now explore how confirmation bias affects our thinking. Here are five ways people use confirmation bias — often outside their awareness — to reinforce their preconceptions.
- Hear no evil, see no evil
- We use many techniques for avoiding information that conflicts with preconceptions. In meetings, we deprive people of the floor if we regard their positions as threats to our preconceptions, or we're inattentive when they speak, or we place their agenda items last, hoping to run out of time. We ignore what they write and we distract others from paying attention to their contributions. For conferences, we use peer review to exclude them from programs altogether; we assign them to small, undesirable, or out-of-the-way venues; we schedule them for undesirable time slots; or we schedule them opposite events that we expect to be heavily attended.
- Consider carefully the spectrum of information sources to which you do pay attention. When others make choices for you (as happens in conferences), think about what has been excluded from the program.
- False memories
- Most research about false memories relates to the recovered memory techniques in common use a decade ago. In the workplace, false memories also play a role. When we recollect what someone said or wrote, we're risking confirmation bias.
- Take extra care when retrieving memories that support positions you hold — memory tends to provide data that supports what we believe, and it tends not to provide data that conflicts with what we believe.
- False reasoning
- When reasoning is subtle, we sometimes make mistakes. But when reasoning isn't especially challenging, we can still make errors, especially when we hurry or we're under stress.
- Because of confirmation bias, these errors tend to favor our preconceptions. Examine carefully any reasoned argument that supports preconceptions.
- False accusations
- Accusations that survive being subjected to testing against evidence are more likely to be valid. By limiting such testing, confirmation bias tends to increase the likelihood that accusations are false.
- Accusations need not be verbalized. Even when they're merely thoughts, they affect how we interact with the accused. Such accusations are especially prone to confirmation bias, because they are rarely subject to confrontation with evidence.

often takes the form of

our preconceptionsoften takes the form of information that contradicts what we hope to be true — information that contradicts our preconceptions. Confirmation bias helps us defend against these contradictions.
- When you sense the presence of an elephant in the room, check for contradictions of the group's hopes, dreams, and preconceptions.
