Emoji
Whether the title contains any emoji character (excluding pure punctuation). Specific emoji types (flag, urgency) are tracked separately.
Emoji are visually distinctive in browse feeds and signal platform-native engagement. They tend to skew younger and more social-media-native audiences. Effect varies sharply by specific emoji — a flag emoji codes as patriotic, a fire emoji codes as informal/youth — so the generic 'has_emoji' binary captures the broad effect while specific emoji binaries refine.
Average Video is the effect on a typical video. Top 10% Video is the effect on the videos that broke out (top decile of views) — so you can see whether a factor helps most videos a little, or pushes the top performers much higher.
