How much certainty can you swallow before it becomes dangerous?
Dr. Mara Voss has made a career out of asking one inconvenient question: How do we actually know that?
Then, during a university public-health symposium, celebrated researcher Adrian Bell holds up an enormous fountain drink and makes a joke destined for the internet: "Our soda sizes could drown a toddler."
Within hours, the remark becomes a viral headline. Activists embrace it. A beverage corporation attacks it. Journalists turn it into a national controversy, and Mara discovers something far more troubling than an unfortunate metaphor: the scientific evidence beneath Bell's confident public claims may not be nearly as certain as everyone has been led to believe.
As Mara digs into preregistered protocols, altered analyses, replication attempts, funding relationships, peer review, corporate counterstudies, and university politics, she finds herself trapped between two equally tempting mistakes-believing experts simply because they are experts and rejecting expertise simply because experts can be wrong.
But Mara's relentless skepticism has consequences outside academia too. Her aging mother is falling. Her estranged sister is tired of having every emotion subjected to cross-examination. And the grief Mara has spent years analyzing instead of feeling is becoming impossible to hide behind another study.
Darkly funny, intellectually provocative, and deeply human, Our Soda Sizes Could Drown a Toddler is a contemporary literary satire about scientific uncertainty, academic ambition, corporate influence, media sensationalism, family, grief, and our desperate appetite for simple answers to complicated questions.
Because sometimes the evidence is weak.
Sometimes the experts are wrong.
Sometimes the skeptics are wrong.
And sometimes we know enough to act-even when certainty never arrives.
