I find it bizarre that people find this problematic.

Even Einstein tried to find flaws in his own theories. This is how science should actually work.

We need to actively try and falsify theories and beliefs. Only if we fail to falsify, the theories should be considered valid.

If scientific studies aren’t reproducible with the reported confidence, it fails as science.

It would be worse if the experiments were not even falsifiable, yes.

But it’s pretty damn bad when the conclusion of the original study can never be confirmed when once in a rare min they try.

These studies didn’t try to find theories, they tried to find results.

In your example, it’s the same as someone publishing a paper that disproves Relativity - only for us to find that the author fabricated the data.
