    Crosscut: revisiting behavioral icons

    It’s striking how certain mid-century experiments linger long after their findings fall apart. Writing in early June, Claire L. Evans looks back at the planarian worms of the 1960s—creatures once thought to transfer memories through cannibalism. While those specific results dissolved under scrutiny, the search for memory outside the brain continues in the stranger corners of biology. Then, Ian Bogost, in a piece from just this week, turns to the famous marshmallow test. Instead of trying to fix the science, the focus shifts to the toll of the "delayed gratification" cult. There’s a puzzle here: when a scientific myth breaks, does it reveal a hidden biological mechanism or a flaw in how we measure a successful life? Claire L. Evans leaves the listener standing on the icy banks of the Charles River with Zachary Kelso, wondering why the planarians won’t perform their old tricks. It’s a story about the ghost of a 1960s experiment—the idea that memory could be eaten—and the persistent hope that some biological truth still hides in those flatworms. If Evans looks at a mid-century scientific myth and sees a mystery worth solving, Ian Bogost looks at another icon from that same era and sees a trap worth escaping. The marshmallow test, much like McConnell’s worms, became a cultural shorthand for how brains are supposed to function. But where the researchers in the Harvard lab are trying to get their subjects to learn again, Bogost suggests the real lesson isn’t in the waiting, but in the eating. It’s a striking contrast in how to handle a legacy. One piece treats a failed experiment as a prompt to look closer at the cells; the other treats a famous experiment as a reason to look closer at the clock. Read together, they suggest that the 1960s didn’t just give us data—the era gave us scripts for how to live and think that are only now beginning to crack. The ground shifts when the icons of the psych lab—the ground-up flatworms and the lonely marshmallows—lose their status as truth. There is a freedom in seeing these mid-century myths crumble. Memory might not be a locked vault in the brain, but something fluid and chemical, just as the choice to eat the marshmallow might be a refusal to trade the present for a promise. What lingers is the vastness still hidden under the skin. If the old maps of how people work are wrong, what else is being missed by looking for order where there is only life?
