Bayesian Data Analysis for Babies

Finally: a statistics book that starts where knowledge actually starts

Everything you know started as a guess that got refined.

Your first taste of food. Your first time being left alone. Your first encounter with a stranger. Each began with uncertainty-a prior-and each was shaped by evidence into something more definite. This is how knowledge works.

Babies do this visibly. They form priors, observe outcomes, update, repeat. Dozens of times before breakfast. They're building models of the world from scratch, one data point at a time.

Bayesian Data Analysis For Babies is an illustrated field guide to this process. It names what babies already do: sequential updating when mom leaves and returns, likelihood estimation during bedtime negotiations, probability distributions when sniffing the air from the kitchen.

The goal isn't to teach babies statistics. It's to show the rest of us what learning looked like before we forgot to notice.

Written in gentle, bouncy rhyme and brought to life with warm illustrations, this book is for curious babies, nerdy parents, and anyone who's ever wanted to explain conjugate priors using a high chair.

Inside this book:

• 7 beautifully illustrated pages of Bayesian wisdom + 17 page isomorphic epilogue in the style of Douglas Hofstadter in the style of Lewis Carroll (to meet Amazon's minimum length requirements)
• Core concepts: priors, posteriors, likelihoods, probability distributions, sequential updating, and more
• Friendly guide "Dr. Quack, PhD"-a rubber duck with glasses who offers technical footnotes for the grown-ups
• 100% compatible with bedtime routines
