Fair enough, I think Kuhn was referring to things like the world-models and you're referring to finding out if the predictions of the model matches reality.

The heliocentric model of the solar system made less accurate predictions than the geocentric model for years, because the geocentric model was mature and had had lots of tweaks applied to it. In that time, you could have asked the heliocentric model to make a prediction, and shown that it was wrong compared to the geocentric model. You would have been wrong to conclude that heliocentrism was wrong though, it just hadn't matured as a theory enough yet.

All models are wrong, but some are useful.
