Let’s get specific and see if you’re right. The theory of classical conditioning says if you present a neutral stimulus together with a biologically significant one, an animal will eventually show the same response to the neutral stimulus alone as it does to the biologically significant one.

Is this falsifiable? Seems like it. You’d just have to show cases where qualifying stimuli are repeated and the neutral stimulus alone provoked no reaction.

In this world, however, we observe that the Behaviorists, who were uniquely concerned with holding psychology to strict scientific standards, where ganged up upon and hounded out of the field. The hounders can't be trusted.
