Why does daniel dennett think that change blindness--that is, incomplete perception that feels complete--poses a challenge for descartes's view of there being an intellect that isn't just a collection of sensory data? (review the video clip on daniel dennett below if you need to refresh your understanding of change blindness and dennett's conclusion about it.)

Change blindness forbids us from seeing, perceiving or collecting data.

Explanation:

Change blindness is the effect in humans where a change passes unadverted by our senses, it could be and it is most often studied in the field of visuals, but also in our other senses, our brain often shuts down stimuli that are not favorable or worthy of the attention in an effort to save us all energy, Daniel Dennett thinks and afirms that in this case there´s nothing like us being a recollection of experiences since we can shut down the perception of worl at will.
