I've spent over 20 years studying conspiracy theory, perceptual psychology and the ways our cognitive systems function and process sensory data. Alan Moore's suggestion regarding information overload appears to be largely correct, and I would suggest that the surge in mental health issues we're seeing in civilized society may be related to this.
For all of our evolution, we are still primates and still run the same 'operating system', so to speak, as our ancestors. The human nervous system hasn't been configured to deal with this new influx of information, which has occurred exponentially faster than at any time in recorded history, and it shows no signs of stopping.
Whether we like it or not, our cognitive faculties are based on pattern recognition; intuition also depends on those same systems.
I could go deep on this, but it's not relevant to the thread and I have no wish to derail it.
Suffice it to say, I've explored this avenue extensively and without turning into David Icke (who is at least 96.531% full of shit).
Perhaps another thread, another time.
