Science here, and in real life, means two things.
Science is a hermeneutic. It’s a focus on proof-by-induction, empiricism, mathematical formalism and falsifiability.
But it’s also something capable of being analyzed by another hermeneutic: politics. Science is something done by scientists, by human beings. And they’re susceptible to bias.
I find the chronic fatigue syndrome focus particularly fascinating because you can see a parallel to the so-called obesity epidemic: science that, when you really look at it, is relatively meaningless: no study has actually shown long-term success, but each one is twisted and spun to imply long term success is both easy and obtainable, thereby implying that the victim of these diseases is to be blamed.
Of course, there’s that clumsy hermeneutic again – science should never be about blame, it should be about what is. Politics is more often about blame, so we should be warned whenever any study could be used to imply fault.
Let’s not even start on the replicability crisis hitting psychology right now.
