Investigating Higher Story Consumption on Instagram vs. Facebook
Context
You observe that Stories are consumed more on Instagram than on Facebook. For concreteness, assume "Story consumption" refers to normalized engagement such as views per Story viewer per day (or time spent on Stories per Story viewer). Your goal is to diagnose why the gap exists and how much each factor contributes.
Question
How would you investigate the reasons behind higher Story consumption on Instagram compared with Facebook?
Hints

- UI/UX differences (tray prominence, autoplay, navigation, latency)
- Social graph structure and norms
- Cohort analysis and within-user comparisons
- Controlled experiments and quasi-experimental designs
- Measurement parity and logging differences
