How do we collect data to test theories about syntax and semantics? For most of us, the process is very simple: We have a hypothesis, we construct sample sentences to test it, introspect about their grammaticality or meaning, and move on to modify our hypothesis as necessary. It would be fair to say that the standard method of data collection in syntax and semantics is personal introspection. This personal introspection is not totally uncontrolled, of course: Doubtful cases are checked informally with friends or colleagues; and there is an implicit, check when the referees accept a paper or an audience listens without objecting. What we have, in effect, is the introspection of the professionals, the people who know what the issues are.
This standard method has been enormously successful: Linguists have produced precise and interesting theories about syntax and semantics; and the bulk of the data on which these theories depend is undisputed and, we believe, undisputable.
