• Yes Karl Popper says that science must limit itself to working on ideas that are falsifiable.

    But that doesn’t mean that we can just go about making life-changing decisions for ourselves or for others based on any beliefs we want and claim science has no say because those beliefs are unfalsifiable. Its the other way around: public policy must be constrained by fact and evidence even if our individual beliefs are influenced by more than that.

    When Hugo Grotius was working on the law of the sea, which became one of the bases of modern international law, he imagined laws that would hold fast even in the absence of God. If we cannot do the same then we are doing no better than throwing rocks at each other for our individual betterment.
