Hegel is trying to understand everything, so he has a tough mission. Anyhow, his lecture notes are clear enough.

>What are logical truths?
A lot of work is done using mathematical reasoning, not testing observations against predictions.

Also, plenty of science isn't predictive. Shit gets falsified all the time and then people just generate ad hoc reasons about why they aren't wrong. Intro to economics textbooks still almost all teach that productivity growth is what drives wage growth despite the two being observably decoupled for 50 fucking years now. They also claim that the velocity of money is static despite that being falsified by 30 years of data.

Much of the research on brain imaging is unfalsifiable. See also, pic related.

Popper is bullshit. No observation can falsify a theory because you can always generate another plausible reason for why X is happening. Popper isn't how science is actually done. Newton's theory was falsified quickly by the planets orbits. Did we throw it out? No, we posited an unseen planet, and lo and behold we found it. Saying something isn't science because it isn't falsifiable is bullshit, it's not how science is actually done, it's just how the very brief intro to philosophy for scientists is framed.

It leads to people calling all of quantum foundations unfalsifiable. But Mach famously thought atoms were unfalsifiable. Quarks were also called pseudoscience because they were unfalsifiable. Now people are upset about parallel universes, even though wave function collapse is totally as hoc itself and also not falsifiable.

Anyhow, if you want to focus of predictability, go Bayesian.
