Why ParentData is different

Not all parenting advice is created equal. Here's how we ensure every piece of information you read is backed by the highest-quality research and rigorous analysis.

icon

Comprehensive evidence review

We review hundreds of studies on each topic, using Google Scholar, PubMed, and medical databases to find the complete picture.

200+ papers reviewed for major topics

icon

Deep dive analysis

We focus on the most cited, high-quality studies from respected journals, understanding their methods and limitations.

Focus on peer-reviewed research

icon

Quality over quantity

We prioritize the best quality studies - those with randomized data, large sample sizes, and objective measures that show causation, not just correlation.

Causation, not correlation

icon

Rigorous skepticism

We're more skeptical than most about non-randomized studies and always work to explain why we prioritize some studies over others.
