Section 1
The premise
Content moderation AI exhibits documented bias against marginalized communities; addressing it requires deliberate design.
What AI does well here
- Audit moderation outcomes by community/topic/language for disparate impact
- Diversify training data to reduce bias
- Build appeal pathways accessible to affected communities
- Engage affected communities in moderation policy
What AI cannot do
- Eliminate moderation bias entirely
- Substitute statistical parity for substantive justice
- Replace community voice in policy
Key terms in this lesson
Section 2
Content Flag Thresholds: Calibration Across Stakes
Section 3
The premise
Content moderation thresholds reflect values; calibration to stakes matters.
What AI does well here
- Calibrate thresholds per use case stakes (CSAM zero-tolerance vs PG-rated entertainment)
- Provide appeal pathways for false flags
- Track false-positive and false-negative rates by category
- Engage affected communities in threshold setting
What AI cannot do
- Get one threshold right for all stakes
- Eliminate both false positives and false negatives
- Make threshold setting purely technical
Section 4
AI and Content Moderation: Reducing Reviewer Trauma
Section 5
The premise
AI can assist with using AI pre-classification to reduce human moderator exposure to traumatic content, but ethical and legal accountability stays with the humans deploying it.
What AI does well here
- Draft policy memos covering content moderation obligations.
- Generate vendor diligence checklists referencing trauma reduction.
What AI cannot do
- Substitute for counsel on jurisdiction-specific obligations.
- Resolve the underlying value tradeoffs between competing stakeholders.
Section 6
AI and Content Moderator Trauma: Pre-Filtering Without Hiding the Cost
Section 7
The premise
AI classifiers handle the high-volume CSAM and gore filtering, leaving humans the ambiguous cases. The reduced volume can hide the increased per-case severity moderators still face.
What AI does well here
- Auto-action high-confidence violations without human view
- Blur and pixelate edge-case content before reviewer load
- Produce dashboards of harm categories and trends
What AI cannot do
- Eliminate the residual human review of ambiguous cases
- Heal a moderator with PTSD from prior exposure
- Substitute for licensed mental-health benefits and tenure caps
