Incorrect use of instance of (P31)[edit]

Hello –

This statement on "pharmaceutical industry" (Q507443) was incorrect, and I have removed it. Errors with instance of (P31) and subclass of (P279) lead to numerous false inferences.. When using instance of (P31) and subclass of (P279), check the description of your value item, and make sure the statement is valid per Help:Basic membership properties. (In this case, an industry is a collection of companies, and manufacturing is the activity they engage in.) There is often another property that can accurately express the relationship you had in mind; in this case, field of work (P101) works better. You can search through available properties here.
