Is progress the exception and degeneration the rule in evolution?

But, Popper was careful to label value judgments as “extra-scientific” ones.

The human scientific enterprise itself is driven by one value judgment: “Knowledge is good.” That is, it is better for human beings to have accurate, tested knowledge about the universe than to remain ignorant.

But that judgment is external to the process of scientific research. The scientific method can never make a value judgment as such, can never abstract an “ought” from an “is.” Science can only try to describe the universe, as it finds it, as accurately as possible.

In that sense, science is “value free.”
