## Streaming Chats
--
**Video Feed + Social Chat: All in one screen.**
--
Popular among the younger generations.
- Twitch (Amazon)
- YouTube/YouTube Gaming (Google)
- Mixer (Microsoft)
- Facebook Lives

## Political Debates

### Bolsonaro's Facebook Lives

### Research Design
**We combine a large scale ''field" experiment" with data scrapped from Facebook streaming chats.**
--
**Three main experimental conditions**
- Control (standard NBC broadcast)
- Expert chat (538 website)
- Streaming chat (Facebook)

## Results
**Main Findings**:
- Creates worse viewing experience.
- Affects perceptions:
- Disproportionately negatively affect certain candidates subject to toxic, negative comments.
- Distort inferences about candidate viability.
---
## Next steps: contextual cues and majority illusion.
