There's not much point in having data that "everyone agrees upon". That's not the difficult part. The problem is, what are you going to do with that data? Do you think that if types unquestionably "exist", then that's all that there is? You are and will always be limited to the current and previous observations of that "type". You can never predict what that type is going to do in the future. Or even in different situations that are yet to be observed, for that matter.

The problem has always been that this is simply Inductivism.
