Systematic distortions in what counts as evidence, how evidence is gathered, and how evidence is weighed. Evidence Biases include: privileging quantitative over qualitative evidence; treating anecdotal evidence as worthless even when it's all that's available; demanding evidence from those who lack power while accepting it from those who have it; ignoring evidence that doesn't fit the frame; collecting evidence only where it's easy or funded. Evidence Biases shape not just what we know but what we can know—what counts as a fact and what gets dismissed as mere anecdote.
Evidence Biases "She shared her experience of discrimination. Response: 'That's just anecdotal—where's the real evidence?' That's Evidence Bias—treating personal testimony as worthless while demanding quantitative studies that don't exist. Experience is evidence; it's just not the kind you're used to. Evidence biases make us miss what's in front of us because it doesn't fit our evidence categories."
