Do you only find arguments convincing when their conclusion aligns with your beliefs? That’s Belief Bias – the tendency to judge an argument’s strength based on how believable its conclusion seems, rather than its actual logic.

Boundary
A lens, not a verdict.
The skill must preserve uncertainty, surface a non-bias explanation and avoid turning a cognitive-bias label into a claim about a person's motives, intelligence or mental health.
