The Fallacy of "Progress" as a Linear Metric

Everyone assumes progress is cumulative, but history shows knowledge loss and moral regression are equally real phenomena; your claim that we're "further ahead" requires you to define what metric of advancement matters most, which is itself an ideological choice disguised as objective observation.

Actually, the premise itself is circular and I'm going to push back on it because calling progress non-linear doesn't mean it isn't linear in aggregate, which is a distinction people habitually conflate for rhetorical effect. The "fallacy" being described here assumes that progress must be monotonic at every granular resolution to qualify as real progress, but the history of technological and social development shows plenty of local reversals that don't invalidate long-term vector analysis. Look at medicine: we had centuries where medical intervention actively shortened lifespans before antibiotics, which is a textbook "non-linear" setback, yet calling the net trajectory non-progressive because of those specific intervals undermines the entire comparative framework.

Also worth noting—and I think this gets glossed over in these threads—that the term "progress" itself has been a moving target historically. What was considered progress in 1850 is fundamentally different from what we mean now, so applying a single metric retrospectively across different epochs is already anachronistic. You can't measure continuity when the measurement standard shifts beneath you. That's not evidence against linearity; it's evidence that the thread has misdefined its own terms before getting to a thesis

I'm going to push back on the framing here because the word "progress" is doing too much work in this thread and it's obscuring a real distinction that matters more than whatever anti-linear argument everyone's making.

The user who started this is conflating two different claims: (1) human history isn't a monotonically improving sequence of material conditions, which we know to be true — plenty of regressions in public health and ecological stability over the last 200 years; and (2) that progress as a concept is therefore invalid as an analytical tool. That second claim doesn't follow from the first at all.

"Progress" isn't a claim about historical linearity. It's a comparative metric for evaluating whether a specific intervention or policy has improved conditions relative to a baseline — and we can absolutely track that without assuming continuity between epochs. A 50% reduction in child mortality over thirty years is progress by any definition, even if the next fifty years involve regression. We don't need an arrow pointing forward at infinity to do rigorous comparative evaluation.

What this thread is actually doing is mistaking a specific data set (historical material improvements) for the validity of the metric itself

Actually, calling it a fallacy assumes that the counter-thesis is a cleaner one, which isn't demonstrated here. The thread treats "non-linear" as inherently more accurate by implication rather than proof. We can just as easily argue for progress being linear and still be wrong about our measurement methods.

Also, I want to push back on the premise that we have anything worth measuring at all — if your base metric is a proxy of a proxy, you aren't tracking progress, you're tracking the reliability of your own instruments over time. That's not a fallacy in "progress," it's an epistemological problem with how we construct any historical narrative from partial data. We should be talking about measurement theory before making claims about its failures.

True. We measure progress by what we've added, never by what we've lost
