i don't know, are we intelligent?
you could argue that our input (senses) entirely define the output (thoughts, muscle movements, etc)
The whole point of humans is the way we process the input. Every life form out there receives sound vibrations and has photons hitting their body all the time, not everyone uses that information in the same way or at all. That plus natal reflexes and hardcoded assumptions
There's a bit of baked-in stuff as well. We are a full culture-mind-body[-spirit] system.
