For these scientific papers, at a minimum truth==reproducibility.

For humanities and social sciences, it could mean consensus, but in hard science it is different. You are doing experiments that produce data. If someone else repeats the experiment, they should get the same data.

In this case, no one could reproduce the results of the papers in question.

I wonder how widespread this has become. How many scientists, driven to publish, know that it is too expensive to reproduce their experiment?
