I think categorization is a survival tool. We have all this data coming at us, and we have to process it SOMEhow (or miss the tiger/layoff/sleezoid coming our way), so we tend to filter/group it as best we can, which includes categorization. As The Police sang, "Too much information, running through my brain!" and we're going MORE in that direction, not less. Like so many of the internal tools we evolved with, there's not a lot of fine-tuning available; not easy to turn off filtering for just some data, unless we get better at pre-processing. Or something.
