Episode notes
How Expecting Better Started As A Personal Project
- Emily Oster began writing about pregnancy because she was frustrated by patronizing advice and wanted to apply her data skills to her own pregnancy decisions.
- She sent a book proposal on a whim, pitched it as a hobby while untenured, and turned it into Expecting Better that blends memoir and meta-analysis.
Why Raw Pregnancy Correlations Mislead
- Observational correlations often disappear after controlling for confounders like age and nausea, so simple raw links (e.g., coffee and miscarriage) can be misleading.
- Emily shows that adding relevant controls can drive associations toward zero, implying small or no causal effect.
Frame Decisions By Listing Real Alternatives
- Frame decisions by specifying realistic alternative options rather than vague 'or not' choices, then commit to a final decision and move on.
- Example: compare daycare to hiring a nanny, having grandparents care, or quitting work, not just daycare versus nothing.
