Takeaways:
- Bayesian mindset in psychology: Why priors, model checking, and full uncertainty reporting make findings more honest and useful.
- Intermittent fasting & cognition: A Bayesian meta-analysis suggests effects are context- and age-dependent – and often small but meaningful.
- Framing matters: The way we frame dietary advice (focus, flexibility, timing) can shape adherence and perceived cognitive benefits.
- From cravings to choices: Appetite, craving, stress, and mood interact to influence eating and cognitive performance throughout the day.
- Define before you measure: Clear definitions (and DAGs to encode assumptions) reduce ambiguity and guide better study design.
- DAGs for causal thinking: Directed acyclic graphs help separate hypotheses from data pipelines and make causal claims auditable.
- Small effects, big implications: Well-estimated “small” effects can scale to public-health relevance when decisions repeat daily.
- Teaching by modeling: Helping students write models (not just run them) builds statistical thinking and scientific literacy.
- Bridging lab and life: Balancing careful experiments with real-world measurement is key to actionable health-psychology insights.
- Trust through transparency: Openly communicating assumptions, uncertainty, and limitations strengthens scientific credibility.
