Cherry picking data is not just done by scientific "denialists" but also some "respected" theorists who are seeking support for their scientific theory.
I recently realised that some experimentalists cherry pick theories to describe their experimental data. I heard a talk by a theorist who reported having several disturbing conversations along the following lines.
Experimentalist: We fitted our data to your theory.
Theorist: But the theory is not valid or relevant in the parameter regime of your experiment.
Experimentalist: We don't care. The theory fits the data.
