Here I am living in the Netherlands, 2019 AD. In my perception there is no two-way explicit communication with non-human intelligence, no space travel. Artifical intelligence is in it's infancy (at least, as seen by the general public). All my evidence to today tells me I this current objective reality is certain.
But now I am asking myself from a rationality perspective: How is this perception of reality is bounded by my intelligence (in whatever way my biological system has implemented this intelligence) and (unaware) filtering of evidence?
If I were able to enhance my intelligence by just 1 bit, changing some personal absolute certainty into something probabilistic, what would be the effect on my objective reality? What would be the effect on our shared objective reality? What experiment could be designed to find out?
