Arguably our storytelling was an efficient hack in an age before writing. A story is a very high-overhead, low SNR way of communicating kernels of truth, but it's robust over time, so it allowed transfer and accumulation of knowledge across societies and generations.

But then we've invented and perfected writing, developed symbolic languages and notations (e.g. math, musical), long-duration storage media for text, and eventually networked digital computers. In terms of communicating and preserving knowledge, stories are pretty much the worst possible option you can choose.

We're comfortable with narratives because we didn't have anything else for hundreds of thousands of years. Stories are pretty much hardwired into our brains. But that doesn't make them the right choice, now that we've figured out much better alternatives.

More than that, I'm personally suspicious of stories being used in communication. There's no good reason to use them, and there's plenty of bad ones - it so happens that what makes a good story robust over time is the same thing you need to manipulate people into believing lies and shut off critical thinking.

The main benefit of stories is that they are easier for people to remember than dry details. In terms of communicating knowledge, they are the form that are most likely to stick with us as opposed to going in one ear and out the other. Especially when it comes to areas where someone doesn’t have expertise. This is as you noted incredibly prone to manipulation, but it doesn’t change that it you want a random person picked off the street to actually synthesize the knowledge you’re trying to tell them, a story is by far the way most likely to work. And I’d say that’s important, since knowledge written down somewhere that no one remembers or cares about does nothing to change the way people act.

As far as preserving information goes, no argument there. Stories aren’t a good way to preserve the truth of matters for future generations. To look and determine if the stories told have truth in them requires more detailed writing.

Stories place ideas into context, not only making them easier to remember (as mentioned by another comment) but also easier to understand. Analytic philosophers are used to dry, precise language, but even they often rely on scenarios and narratives -- this can help reveal what the reader thinks intuitively and bring that into sharper contrast. By remaining story-free you're giving pedagogy the short shrift.

What has empirically brought more folks into careers in science, dry textbooks foisted by teachers or Star Trek? I'd argue Star Trek and science fiction more generally. You can chalk that up to human failings if you like, but inspiration is a need that can't be avoided if you wish to convince.
