Journalists who misrepresent the results of a study to get clicks. Companies that purposely design erroneous experiments to get the results they want (a la the tobacco example elsewhere in this thread). Individual scientists who corrupt their own studies or falsify data to advance their own careers.
>Also, science, the classical definition, has no meaning on its own. It’s simply way to describe reality. It’s usually up to engineers and people to put into practice.
This makes no sense. Science is the process of refining the model of the world by testing hypotheses by performing experiments and then revising the model as new data is collected. This is in contrast to something like religion, where the model is not to be altered regardless of the data.
