Intuition the name we give to the human capacity to process subjective data that often combines a mixture of perception, experience, expectation, understanding of context, and reading of how a shift can reflect a change between some of these factors.
To use
@fairnymph 's example - I might have had prior experience of driving along the highway at a certain time of the month, during a certain time of the year, on a certain night of the week, and particular hours of the night, to expect more police presence, especially when it's springtime and a game is happening in the city, and we're close to the weekend, and people have seemed more prone to drinking/driving lately based on recently observed swerving behavior I"ve noted over the past few weeks....
I can both rightly assume that police are also keying into these factors, AND, I'm more apt to note that I was correct to myself when I finally do pass police, thus further reinforcing whatever pattern and context I'd noted as being representative of an accurate predictive pattern. While I couldn't sit there and watch a video of the same traffic flow at random and likely predict whether it would be a night more likely to have police out, sitting within it and having sat within it more and more times previously will make me more apt to notice it.
Also, If I'm someone who believes that I'm capable of this type of predictive pattern recognition and intuition might make me better at it than someone who thinks about things through primarily an objective or sensing style of mentation.
This type of mentation is reflected by xN/Sxx in the Meyers Briggs Type Index, with N representing intuition whereas S represents sensing (reasoning based on what is directly observable in the moment rather than relying on ones gut or deduction of what's probable).
