Yes. In experiments that easily *could* give results contrary to what QM predicts, the actual results agree with QM. That often involves very elaborate devices to detect the results. Sorry if that offends you.<quoted text>
Under carefully contrived and controlled experiments?
But, the results of QM also work even in the 'wild'. It is at the heart of our understanding of solids, for example: why do metals conduct electricity bu elements like sulfur do not? How to atomic bonds form? Why do materials react to light the way they do?
Once again, quantum mechanics is part of the best predictive theory of physics we have ever had.
