Many definitions of story emphasize the fictional part. However, there’s one major definition that gives a wider, and in my view more accurate, interpretation: “A narrative, either true or fictitious, in prose or verse, designed to interest, amuse, or instruct the hearer or reader.”
But back to hypotheses — and vocations. People become scientists because they want to tell stories, preferably exciting, original ones; and once trained in their discipline they weave stories without cease — stories that attempt to explain how the universe and its inhabitants are made (they also explain why, unless someone insists on intelligent design or intent). Before the stories go into the testing crucible, they’re called hypotheses. Observations or measurements are done in the framework of a story at its hypothesis stage. If a story jibes with reality, it gets renamed to theory. To put it succinctly, science cannot be practiced without stories, without the call and response between story and world. The stories dictate what experiments/observations get done; the stories, to some extent, dictate what conclusions are drawn (and thereby can bias the venture, as all powerful stories do).
Athena Andreadis, who knows whereof she speaks. The sociologically-minded will note the clear echoes from e.g. Haraway and Latour and other STS headz in this description of (techno)science as a narrative endeavour. However, the importance of the “sensawunda” aspect doesn’t always make it through, and I’m interested in working with the notion of the technoscientific imaginary to see if there’s a way to bring that forward.
