Confirmation bias is the tendency to interpret new information as confirmation of one’s existing beliefs and theories (more on that here). Although confirmation bias can distort our judgment, there are reasons it can sometimes feel useful or efficient:
- More efficient decision-making. Confirmation bias can help us process information more quickly and arrive at decisions sooner, although faster decisions are not necessarily more accurate.
- Deeper engagement in topics we are already interested in. Our tendency to focus on what we already know can sometimes help us develop deeper expertise in those areas.
- Recognizing familiar patterns. Relying on past experiences can sometimes help us notice familiar warning signs and red flags. However, it is still important to consider evidence that does not fit our expectations.
- Team cohesion. Shared beliefs and goals can sometimes help bring people together. However, when people focus only on information that supports the group’s existing views, it can also make it harder to consider alternative perspectives.
On the other hand, the negatives include flawed decision-making, resistance to new information, and reinforcement of incorrect beliefs. It’s important to be aware of our biases and work to reduce their negative impact.
How to Complete the Confirmation Bias Test:
The test below lists behaviors associated with confirmation bias and explores how we process information in general. Think about your social interactions, your opinions about certain people, your investment decisions, your ideas about a healthy diet or lifestyle, or work scenarios where you are presented with new information, and check the statements you can relate to.
