" ... And if neutrinos and this new scalar field interact in this exact way, we'll not only have our explanation for dark energy, we'll actually be able -- experimentally -- to tell. It's the best kind of new theory: testable, falsifiable and Universe-changing, if it's correct! ... "
" ... Instead, whether something is "science" is most useful to convey to the layperson how much weight they should put on various research. And to this end I think Gobry is completely wrong that "randomized trials good, non-randomized trials bad" is a useful heuristic. After all, there are plenty of randomized trials done with 12 people in laboratory conditions that have little to do with reality that should receive little weight in our beliefs. And there are large scale, well-done econometric studies that should be given a fair amount of weight in our beliefs. Whether something is a randomized trial or not is but one dimension among many in determining how we should think about it. If you need to boil what is scientific down to a single heuristic, a better criteria than "randomized trials or not" is whether it is falsifiable. You can falsify a lot without randomized trials. The long-run Phillips curve, the idea that productivity shocks can fully explain the business cycle, the claim that the gold standard will lead to economic growth, and a litany of other zany ideas have been thoroughly debunked by economists using tools that Gobry finds unscientific. While there may not be as many economic claims that we know are true, there are certainly a good amount that we know are false. ... "
" ... Significance also depends on the structure of the hypothesis. Alejandro started with a hypothesis that declared, “Some of the people in my target audience will like my idea.” This is falsifiable, though too general. It can only be rejected if absolutely no one finds any redeemable feature in his proposed service. This evolved into, “At least 5% of the people entering Yellowstone National Park show sufficient desire for additional information that they would stop at a road-side kiosk.” The conditions for falsifying this assumption are much clearer and actionable. However, the thresholds for significance must be tailored to each venture, with little assurance that they hit the sweet spot between overly strict (which would cause an entrepreneur to ignore a feasible but non-obvious business idea) and overly loose (which might signal the entrepreneur to launch an unprofitable idea). ...
