reasoning

You ignore information that disagrees with your prior beliefs.

The disconfirmation bias leads you to spend more cognitive effort scrutinizing and attacking evidence that contradicts your existing opinions.

When presented with balanced arguments on a topic, you treat opposing evidence as inherently flawed while accepting supporting evidence with minimal scrutiny. This creates an uneven standard of proof that shields your current worldview from external challenge. The more firmly you hold an opinion, the more aggressively you dismantle conflicting data.

You do not seek truth; you seek validation.

One of these every day, and every one names the study it came from. When a finding is contested, it says so.
